Cooling tips

[Harry Bloomfield]

Yes so if you had no windows and never opened the front door or letter box then or had any appliances that produce heat - then a well insulated house will stay nice and cool in the summer.

Only for a while, until the heat seeped through the insulation, then you would need to find a way to cool the interior down.

That's all you need to get your head around.

You mean that insulation which reduces the amount of heat leaving a building also reduces the amount of heat entering the building?

Sounds lovely like a conspiracy theory to me.

Ideally, you would also avoid any human occupants.

In Spain I have seen that they have external metal shutters that you operate from the inside that keep the sun out totally. If you have a particular facing aspect - shutter down when you go to work and come home later when the sun is off that part and then open them.

Limited numbers of inhabitants don't alter the summertime internal temperatures significantly, on their own. The biggest issue there is winter temperatures and moisture.

Again - insulation is your friend.

External shutters is the traditional way in many hot countries. It completely avoids the tremendous solar gain through glass. Along with white exteriors and white roofs. External blinds are becoming more popular here. A few years ago they simply didn't seem to exist. But many are now putting in massive patio doors as a feature and realising that the solar gain is a big problem. But external blinds seem to be ridiculously expensive. When I had a quick Google, they seemed to start at £2K+ for a patio door.

An awning makes more sense, as it serves not only as a solar blocker from heat gain, but also offers shelter from both blazing sun and drizzle / rain.

I looked into an awning that winds out but struggled to find a waterproof one as I wanted it to wind out when I had a BBQ planned but rain is forecast. I found "shower resistant" and that was about the best I could but we all know what shower resistant means

My point was that a shutter is a lot of money for only one purpose, whereas an awning would serve an additional purpose, but for much less cost.

Yep but I suppose shutters will add security

Poor conductors of heat don't cease to be poor conductors of heat after breakfast, lol.

So are you saying that normal house insulation is 100% effective and lets no heat pass.
Unless you live here.

Fair point, but I would expect that my house would be pretty secure to start with, without the addition of £k's worth of shutters per door and window.

No, I'm not saying anything of the sort.

 

[motorbiking]

Nonsense.

Please read more thoroughly. And at least understand what you do read.

I genuinely thought that you would need knowledge of this subject in your day to day work. But it seems not.
