What tips do you have for keeping your house cool in these temperatures?

[-]

heatherbee84@reddit

Close curtains/blinds on the sunny side until the sun clears them. If you have a loft hatch, it can help to open that at nighttime as in theory the warm air from your house moves into the cooler loft.

[-]

sneezetree@reddit

If you can set any sort of shade OUTSIDE the glass, it’s even better. I had some old bedsheets that I attached suction cups to the corners and stuck to the outside of the big south facing bifold doors we had in my previous house. It made so much of a difference compared to shading inside.

This morning I set up a sun sail awning outside the new place’s biggest window. It looks much less diy than the bed sheets 😂 we’ll see if it works as well over the next couple of days.

nathderbyshire@reddit

Tinfoil works on the inside in a pinch as well, dramatically reduces the heat from direct sunlight. I'll be prepping my windows for tomorrow. I wish I did it today

https://ibb.co/SDyzXx49

My bedroom and kitchen window are on the same side, the blinds do a lot of the work but because the kitchen one has been open a bit it's way hotter in there than the bedroom which has been fully closed.

I keep meaning to get some of the reflective boards but for each big window it costs way more than foil which I can just fold up and reuse until the heat goes then it gets folded up and used as tin foil should again lol

[-]

ChelseaMourning@reddit

I’ve tinfoiled my bedroom windows at 7am today. The sun beams in until midday and even with the curtains closed, it still heats up. The curtains were hot to the touch yesterday, but cool the same time today with the foil.

[-]

SeaIntelligent4504@reddit

Exactly this. Inside, but against the glass works as well. It means that none of the air inside the room becomes heated.

[-]

sneezetree@reddit

I’ve been told to be careful with inside/against the glass, mostly in the context of the reflective privacy/uv vinyl stuff and double glazing. The sun gets through the outside glass & super heats the glazing void which can cause thermal shock cracks. I don’t know how common this is, but the theory sounds reasonable. Plus the window becomes a radiator.
Better than nothing I suspect, but thermal curtains with a bit of air flow is safer.

[-]

SeaIntelligent4504@reddit

eek good to know! I just sellotaped some underfloor insulation to the windows (white side out) in desperation last year and it worked really well to I put them on again. They aren't completely flat to the glass as they still have the bow from being wrapped in a cylinder and not taped the whole way round, so hopefully ok.

[-]

sneezetree@reddit

ha, good use of what you have to hand! I suspect you are fine with that setup.

AirIndex@reddit

I remember in 2022 when we had that week of 30+ temperatures. By the last day our upstairs was 30 degrees and it was unbearable, and then we opened the loft hatch and it INSTANTLY cooled a few degrees.

EmperorsChamberMaid_@reddit

Same. I often find my loft is still 28 degrees while the house starts cooling to 24. Opening the loft door just warms up the house

[-]

sneezetree@reddit

hot air rises, its about giving that air somewhere to escape to. if your loft floor is really well insulated but the roof itself is ventilated, opening the loft hatch gives hot air a route out of your upstairs rooms & out of the house. it creates a draft too as the hot air gets replaced at ground level (like a chimny). if your loft is converted then hopefully the roof itself is well insulated and cracking any velux type windows is needed to give the air that route out past the insulation.

[-]

mootymoots@reddit

My loft is the hottest area of the house. Easily +3C than upstairs. Stays much hotter in summer than rest of house

geekroick@reddit

Exactly.

First time I went to Italy in the summer of 2021 I was amazed to see how quiet and abandoned the residential areas seemed, because they all had shutters and blinds and whatnot fully closed, to prevent the sun from making it inside their homes in the first place.

[-]

karthie_a@reddit

open all windows curtains early in morning and when sun comes up close the blinds and curtains leave the window open after sun set open the curtains and blinds. Avoid ice cold drinks and ice creams they actually increase the body heat. Drink a large glass of coconut water in morning. Batch your chores and go out only if required. Try to wear cotton clothes and do not skip wearing inner garments they soak the sweat and keep you cool.

Stinkinhippy@reddit

big b*stard fan.. like the floor standing 24inch air circulator jobs. On low if i just need some relief during the day. in the evening as soon as the outside air is cooler than inside, i'll pop it in the open front doorway and crank it... Can feel it pushing cooler air all the way up the stairs and into the furthest bedrooms.

Aedaxeon@reddit

Search for "floor fan", they're usually 18 inch. I have a Challenge one from Argos and it's fantastic in a plastic-roofed conservatory. You don't point them at yourself to cool you directly, you use them to force air flow in the direction you want.

If you're going to use fans, have two, spaced apart. (Think of a triangle, they're at two points and you sit yourself as the third.)

Old sandstone is also quite good for regulating temperature. Though for the loft conversion bedroom air conditioning is required when the sun is beating down on the slate roof.

What brand/kind did you get? I'm shopping. I've never lived in a house with the tilt from the top windows, only old sash windows, and I'm worried about how to fit the a/c pipe duct hose thing.

disastrousgreyhound@reddit

If you’ve got sash windows then you should look into getting a proper window unit. They cool the outside air before blowing it inside and the whole hot side of the ac stays outside. This means they’re much more efficient than the standing units!

[-]

SallyJaneCooper@reddit

No, I wish we still had sash windows because then I would get a proper US style window unit. Pop in pop out. But we moved I to a "new" Victorian with double glazed windows that move outward from a hinge at the top.

I grew up in the southern US so all I know is central air. These portables and mini splits are confusing.

[-]

cypherspaceagain@reddit

I bought one last year too. I figured the summers aren't going to get cooler, the units aren't going to get cheaper, so why continue to suffer through the heat just because of some misplaced sense of pride? I probably waste more money on uneaten food every year than the cost of an aircon unit.

I got one two weeks ago as I knew as soon as it got hot they would sell out. So far it is worth the money. I have not felt hot once! I decided to spend a little extra money on one which is an air con, fan, heater and dehumidifier all in one as that way can be used all year round so seems more worth the money.

I “borrowed” a large piece of Perspex from work after Covid and cut it to the size of my window and put a whole the size of the hose in it then used strong double sided tape to attach it to the window and left the actual window open.

We did what the other have commented (the fabric window kits) last year. Although they work they aren't the prettiest and can be a bit of a faff to put up due to different sized windows etc if you leave them up over winter they get dirty, but a faff to install again every year.

We got a seal kit from Amazon. Can't seem to find a legitimate retailer that sells them.

After testing last year the one that works best for us is one designed to go over a door (ie it covers the entire frame rather than trying to just seal the triangular gap between the window and the frame) and then I just moved the Velcro so it fit properly.

insulation on most houses is designed to work with winter temperatures meaning that it is designed to keep the heat inside the house. believe it or not, the PIR insulation or glass fibre insulation won't help much in the summer when you want to keep the house cool

PersonalityWinter382@reddit

Pretty sure insulation doesn't care which way around it is. It stops heat transfer, so if it's warmer outside than in then insulation will help to keep it that way.

This works if the heatwave is short but the temperature gradually increases inside the house the longer the heatwave lasts

[-]

gyroda@reddit

My family insist on doing the opposite and it drives me crazy. And the moment it gets dark they have to close all the curtains and blinds, restricting all the airflow that would cool the house!

Also, if you're going to have a shower at 9pm, open the fucking window and blind and shut the bathroom door afterwards! The glass is textured, nobody will see you, and we don't want all that warm water and air in the rest of the house.

Your house is a thermal battery/thermos - it'll keep the heat/cold for as long as you let it. You wouldn't open all your windows in the winter when you want to keep the heat in, so don't do it in the summer when you want to keep it out!

Competitive-One-8210@reddit

Get a loft fan. It replaces the loft hatch and sucks all the hot air from inside the house and blows it out via the attic where the build up of hot air sitting above habitable rooms is the greatest. You need to have windows very slightly open in the rooms you want to cool so allowing air to be sucked in from outside. There are several examples of these easy diy attic fans on YouTube. Leave running at night for a comfortable nights sleep.

How much is that much? A router can easily 50/60°, it's just a small area so it's not majorly noticeable but the more you have the more it adds up. My router and all my bulbs are quite warm to the touch, Xbox absolutely roasts in summer I'm surprised it works at all, because it's semi enclosed in a unit with just the front exposed along with the TV the whole area feels noticeably warmer when they've been on for an hour or so.

The cupboard that stores all my tech and has a couple mini PCs and some drives, network switch and so on is really warm as well, haven't checked it today actually. The cat likes it in there it's so warm which makes it a pain to dust all my tech

Yeah if you’ve got a gaming pc or a console it’s gonna get hot of course, but watching tv for an hour etc isn’t gonna add much if at all. I avoid gaming in summer tbh and just go for a walk so coming into a cooler house is nice then lol.

LettusLeafus@reddit

It works well for us and my husband is like the geek ultimate boss with his own server rack in the garage and a man cave with more flashing lights than an arcade.

Being in a new build with great insulation really helps keep the heat out and slow down how quickly the house heats up. Making sure I get a through draft from one side of the house to the other and adding a fan blowing out about half a metre from the window to draw more hot air from the room.

For when things get really bad a 2L come bottle filled with water and frozen to use as a cold water bottle at night really helps. Wrap a towel round it and press against the femoral artery.

[-]

annedroiid@reddit

The logic is the same regardless of how hot or cold it is outside. If it's hotter inside than it is outside and you want it to get colder, open the window. If it's hotter outside and you want to stay cool, shut the window.

If your electronics heat up your flat enough that it's warmer than it is outside right now you've got bigger issues.

LolaWithTheGreenEyes@reddit

I think it very much depends on how the house is situated. I keep the windows closed on which ever side of the house the sun is on and open the others on the shaded side. I have a cantilever parasol over my patio doors and it makes a ton of difference. Upstairs I have to rely on venetian blinds. We should be building houses with shutters!

Live in Australia for a while and you might rethink that. You also have to insulate the windows, though. Cheap foam sheets cut to size over the windows make a noticeable difference, even more so if they block sunlight from entering too.

Real_Chard5666@reddit

Top floor windows open, a few windows open on the ground floor, curtains shut where the sun is shining. Natural convectional air flow will draw cool air in low down and exhaust hot air out of the higher windows.

[-]

SassySirennn@reddit

Tried, tested, and genuinely works. I’ve done this every summer for the last 10 years.

During the warmer months, open the house up as early as possible, ideally between about 6am and 9:30am, while the air outside still feels cooler than inside.

Open windows on opposite sides of the house to create a through-draught. Open internal doors too. If you have upstairs windows, open those as well so the warm air can escape.

Then, before the sun properly gets going, shut the house down. For me, that’s usually around 9:30am, but it depends on the time of year and which way your house faces.

The basic rule is:

If it’s hotter outside than inside, keep the windows shut.

If it’s cooler outside than inside, open them.

Also, close curtains or blinds on any sun-facing windows. If you need some windows open, at least close the east-facing ones in the morning, south-facing ones through the middle of the day, and west-facing ones in the afternoon/evening. Personally, I just shut the whole house down once the cool morning air has been let in.

Fans also work, but only if you use them properly.

In the early evening, once the sun is no longer shining directly through the windows but it’s still light outside, I open my north-facing landing window and my south-facing bedroom window.

Then I place a fan about a metre away from the bedroom window, facing out of the window. Yes, blowing air out, not in.

This helps pull warm air out and encourages cooler air to be drawn in from the other side of the house. It creates a through-flow and can cool the house down surprisingly quickly.

You can also do this between downstairs and upstairs windows. Warm air rises, so open a cooler, shaded downstairs window, then use a fan upstairs facing out of a warmer window to help pull the hot air out and draw cooler air through the house.

It sounds counterintuitive, but it works: cool air in when it’s cooler outside, windows shut when it’s hotter outside, and fan blowing out in the evening to flush the heat out.

[-]

karamban@reddit

Do you know if it's better to have the sun facing windows open a crack when you close the curtains? Prevent too much hot air building up through the day

[-]

SassySirennn@reddit

No I would not recommend that at all. The aim is to get the house as cool as possible in the early morning and then trap that cooler air in. We have a new build so while it’s made of cardboard it’s fairly good insulation.

If your home is older, then it made dissipate that cooler air air quicker. I would not recommend opening the south facing windows even a crack.

If you must then I would open the north facing. There will be cooler air sitting there is the shade which could be pulled in.

[-]

another_awkward_brit@reddit

Other than keeping our the heat as much as possible when it's hotter outside than in (including keeping blinds & curtains closed on the sunny side), and getting as much cooler air in when the other way round there's not much else.

It takes some planning, and making sure everyone understands the laws of thermodynamics, but it can be highly effective.

Insulation. My house is a comfortable 18c today with the windows open. Toasty in the winter too as we barely turn the heating on and when we do it's low.

Sorry not super practical for today but honestly, insulation is the only real answer. Get a high powered fan and create a draft from opening windows and/or doors when it's cooler outside.

Railuki@reddit

Things that save me:

Keep curtains closed before the hottest part of the day is over (usually 2/3pm) - especially important if the sun is in your window in the morning.

Get a cooling towel (you can use any flannel really) and use it to rub cold water over your body, then hang it around your neck so it cools your veins

Keep overhead lights off. They generate a lot of heat. I have some rechargeable lights I use instead so I can see with the curtains closed.

Keep as much electrics off as possible. You’ll probably want a fan on though, and you can get some with water which cools the air - if you live somewhere humid already then skip that and stick worth a regular fan.

Been much better since I started keeping all the blinds closed until the sun clears, windows closed in the day and open during the night, fans to keep the air circulating. When it’s cooler I try and create a wind tunnel by opening windows/doors front and back. We have had to buy portable air cons for the bedrooms as my kids struggle with the heat

JonJo42@reddit

We purchased thermal blackout blinds and fixed them to the window frames. They are pulled down when the sun is shining on that side of the house. We also use fans in the rooms to move the air around. The fans and blinds reduce the indoor temperature by 5°C.

At night we open all the windows to let the cooler night time air into the house.

Seriously looking at installing air conditioning soon.

Stop radiation entering the house....so keep windows and curtains closed....the when sun sets, open as cool night air blows through

If you want to help have a fan...facing the open window so will help move warm air out

vishbar@reddit

There’s honestly no replacement for AC.

You can do all these tricks that may or may not work, might make a bit of difference or whatever. Or you can just spend the £1800 (for a split system) or £300 (for a portable unit), push a button, and solve your temperature issues in a heartbeat.

[-]

InevitableFuture26@reddit

yes, we have the split units, had them about 8 years I think now, and were worth every penny.

[-]

TheZZ9@reddit

Yep. I have a conservatory and have a split unit AC which heats in winter and cools in summer. And they are very efficient and economical heaters. Keeps the conservatory comfortable all year round.
You can get ones that use R290 which is not an F Gas so you can DIY install them. Easily doable by a reasonably competent DIYer. You don't even need gauges, vacuum pump etc.
And they come with wifi so you can program them to come on at a certain time etc.
Just remember, when using it keep the door closed! So many people think opening the door "and getting a breeze" helps the AC when all it does is let hot air in and the cold air out.

shut curtains on the side with the sun and open the window behind them. also open the window on the opposite side of the house to create a flow of air.

shutting all windows during the day is a bad idea, your house is going to be as hot a a oven when cooking a roast

ice cream in the fridge is also nice to keep the brain fresh

Keep the curtains closed to block the sunlight from getting into your house.

tandtjm@reddit

First, if you have a loft, open the hatch. The hot air rises into the roof space rather than your bedrooms. Second, get a small electric fan and point it to flow over a bowl of ice and onto your bed while you sleep. It melts throughout the night but the air from it is cooler overall.

My best tip is this - go into the loft for something and stay in there for a good 5 minutes. Back down the ladders, onto the landing and BOOM, man’s not hot.

[-]

No-Reason-8205@reddit

Shut the windows and curtains in the day. Open the loft hatch. In the evening open the window furthest from the front door and the front door. Put a fan facing away from the front door pointing up the stairs to help push the cooler air in.

I did it the cheap way. Half a fridge box opened up and covered in tin foil. It's been up I'm my south facing bedroom window for what is now it's 6th summer. It's getting a bit battered, mostly from up and down (I take it down at night to open the window) and winter storage, but I reckon it's got a couple of of years left.... When, as I haven't needed a new fridge in that time, I will have to either go scouting for a new box side, or buy a car shade.

We installed ceiling fans throughout the house, back curtains closed as that's the sunny side, currently laying on my sofa nicely cooled.

kipha01@reddit

All all curtains closed on the light side with he windows wide open. Any heat generated because of the glass just goes out the window. The all windows open the shaded side because it lets cool air in.

Keep the hot air out, close windows & doors
Keep the sun out, close curtains
Keep the sun off your brickwork, block that radiation with a solar canopy where you can.

If it drops down enough at night you can open windows high upstairs and low downstairs.

When the heat finally sinks through I've used a sprinkler on the south roof and wall to get some evaporative cooling going.

[-]

FourCats44@reddit

Embrace the heat, surrender to it and become one with it.

Take hot showers. It's like 10 minutes of uncomfortable and you feel cool for like 40 minutes afterwards. Also exercise, staying hydrated. Body warms up so you don't feel so bothered by the heat

[-]

Puzzledandhangry@reddit

Embrace the heat, have hot showers and exercise?? Are you nuts?? lol

[-]

FourCats44@reddit

Firstly probably yes.

In the same way that water isn't wet, your skin feels the wet sensation, the same applies to heat. If you try to make your body cool, the difference between your skin and the air is greater and you will feel the heat more.

If you make your body warmer then the heat is less pronounced and less bothersome.

[-]

My mum always drinks tea in the heat, same principle. I just can’t imagine having a hot shower but I totally see your point.

As well as the other things mentioned I've found that the snow/ice covers for car windscreens work. The quilted ones with a shiny side. Put them against the window, shiny side out and they are great at reflecting the sun.

[-]

thatbloke83@reddit

Wife is Spanish and is frequently aghast at the lack of knowledge here...

In short - keep windows closed, and especially on the sunny side of the house keep all windows/blinds fully closed. Consider solar blackout blinds/curtains if it continues to be a problem.

Use a fan to keep air moving around

Also consider a portable AC unit... Now that I have a 10 month old I now have 3 such units - one for my own bedroom, one for kiddo's room and one to move around the house

[-]

SaintJudy@reddit

I'm currently halfway through today's job of putting reflective film on all the windows. They do block out a lot of light so I take most of them off in the winter, so this is an annual job. Worth it though, it makes a difference of several degrees

[-]

bondinchas@reddit

Open all the windows on the shady side of the house, upstairs and downstairs. When the sun moves round, close the windows where it's now sunny, and open those now in the shade.

With all windows open on the shady side only, the coolest outside air is on the ground next to the house, this encourages warm air inside to convect out the upstairs windows.

Also keep curtains closed or partly closed on the sunny side, the glass and curtains may then get hot, but not the contents of the room.

[-]

Netlifeathome@reddit

Insulate the loft to the minimum 270mm and then insulate it some more if you can. If renovating at any point, insulate all the walls in each room as it helps a massive amount during the winter too to keep heat in.

[-]

Last night, I discovered my other half had only turned down the temperature on the heating with the override instead of on the schedule like he was supposed to do it reset as soon as it got to the next time slot.

If you're going to use fans, have two, spaced apart. (Think of a triangle, they're at two points and you sit yourself as the third.)

It creates what I call the "zone of tranquility". I'm actually a little bit cold now.

Buy a fucking portable aircon unit BEFORE summer hits. They’re £200-£300 on Amazon. I’ve got one in each bedroom. Can’t afford multiple? Cool one room down then shut the door and wheel it to the next. Christ, we’ve got electricity and people complain year after year about being hot. Do yourself a favour and just buy one lol. I’m not well off btw, I live in a 2.5 bed (third room is a box) mid terrace. I just decided one year to use a few quid from my savings to change my life.

So the windows you mentioned are a good start.

[-]

regulator202@reddit

Every heatwave I decide I need to heatproof the house for future waves but I never bother. Ideal solution from what I've read is, on top of the usual strategies, to shade the windows externally with external blinds, shutters or awnings.

I'm sure these will become much more common as we get more frequent and longer lasting heatwaves

[-]

annedroiid@reddit

Not sure if it's just me but every year I forget to do it until the heatwave starts, at which point it's too late. Then by the time it cools I have other projects on my mind.

No-Prune5287@reddit

What works for our house is to open up all the internal doors followed by the loft hatch, to allow the air to circulate round and move up.

[-]

Anxious-Designer9315@reddit

Open all your windows at night when it is coolest to let the air in and cool the house down. Then in the morning close all your windows and close the blinds/curtains too to keep the heat out. Don't open the windows again until the sun is on its way down.

Once it's cooler outside than in, you can put fans near windows (pointing into the room) to draw the outside air in, and help things circulate.

Bowls of icy water in front of fans can help you feel cooler too.

Probably obvious, but don't use things that create heat during the day - washing machine, dishwasher, oven etc. You can turn your boiler off too unless you need hot water. Leave it all until later in the evening/ night if you can.

Use fans to conduct airflow. Vent the roof/top floor rooms so heat will rise. Dehumidifier.

I am considering a portable a/c, but am wobbling because I've been told that they put heat in the house which they then work harder to pull out so it's sort of a circular battle.

[-]

just_jason89@reddit

If you're getting an "real" portable AC then you'll want a window kit that let's you put a extract duct out the window.

Shorter the duct the better.

I say "real" because I've seen a lot of fans lately claiming to cool down your house.

You also get the units you have to fill with water, work a little in 20c(ish) temps bit not in the higher. Also need to replace the water often. They basically pull air through the water to cool the air down.

But PROPER portable AC will have a ductthat goes out a window.

[-]

NoodleCheeseThief@reddit

Water ones are called air coolers (not air conditioners).You are right they work in lower temps. They can also work in higher temps if there is plenty of ventilation (i.e cooler is bringing air in from outside and humid air is going out from a far away window. Otherwise, you are creating a stream room.

[-]

gyroda@reddit

Yeah, the water ones work by evaporating water. This increases humidity and gets less and less efficient the more humid the air is.

[-]

QuaintStaircase@reddit

They don't technically put heat back in the house (as long as it vents out a window) however they do pull hot air back in from outside. Everything it vents out the window needs to be replaced, and the only place to replace it from is the hot outside air.

If your house is warmer than outside, e.g. at night, it'll work incredibly well and you almost get 2 for the price of 1.

If outside is warmer than inside, then yeah it'll keep the room it's in cold but it'll be working hard for it.

[-]

BobKickflip@reddit

Yeah, in previous house I've had two fans in the living room, one to pull cool air from the hallway, another at the window to put hot air out. Later bought an aircon unit but you need the window cover to put the pipe through, then they really do work well. They make noise but it's better than the heat!

[-]

fatknits@reddit

I have a portable AC and it's a lifesaver for the hottest days. It can usually get my room a good 10 degrees cooler than outside, and it costs about £1 an hour to run. Which I know is a lot, but I will happily pay £5 a day to run it in the hottest parts to be comfortable.

I've never noticed an issue with it putting heat in the house, especially if the vent hose is insulated through the window (I just have a big sheet of cardboard with a hole for the hose)

[-]

Sea_Lawfulness_9254@reddit

Honestly we’ve just bought a new house (new build) and the first thing I did was pay to have air con installed. I’ve got a unit in the living room and main bedroom and it honestly didn’t cost as much as you’d think. It’s not even that bad in running costs as the units are very efficient. It was great for when it was colder too as we used it to blast some heat in when we need it. The house uses a heat pump so it takes a little while to heat up. Best money I’ve spent to be comfortable.

[-]

KelpFox05@reddit

Other people have given good advice, but also consider cooling your body down in addition to the house.

If you don't have to be anywhere/be presentable at all, dunk your hair in cold water. Evaporation will cool you off. Otherwise, towels soaked in cold water around the nape of your neck where blood runs close to surface, it cools your blood off which cools the rest of you off very efficiently. You can do a similar thing with running cold water over your wrists.

Stay hydrated, if you're not peeing every 3-4 hours then you need to drink more water. Ice lollies are good (you can make them yourself, ice lolly moulds are a tenner on Amazon and you can fill them with whatever hydrating fluid you may desire. Avoid alcohol, it's fun for sure but it's a diuretic so it means you need to drink even more fluid to keep up and it increases your risk of dehydration and heatstroke.) Sunhats if you're going outside, especially between midday and 3pm, it protects your skin but keeping the sun off you helps to keep you cool. Loose, baggy clothing in breathable fabrics.

Your main goal here is to avoid dying of heatstroke, which a remarkable number of people do every summer. Everything else in your life should be secondary to not dying, because if you're dead then you can't do much of anything.

In our house I rotate which windows are open, as soon as the sun starts hitting a window I close them and shut the blinds. I keep to rest of the windows open to encourage airflow.

I have various wireless thermometers around the house and I use that to gauge when to open the windows.

Check the hourly temperatures for where you live. Here (south east), it doesn't really cool down til 1am and doesn't heat about again really til 9am so if you're closing at first light you're missing a good few hours of cool air. I open when I go to bed and close again around 8am.
