Triple glazing windows turning my house into an oven

stevek93 · 20-07-2021 8:20am #1

Hi all,

I got triple glazing installed in my home last year and now with the warm weather they are like a door into a stove, the sun is beaming on them all day until the evening when I touch the glass I could nearly fry an egg on them.

I thought triple glazing would stop some of the heat from the sun? Is there anytime I can do about this, it is like having a radiator in each room on all day it is ridiculous.

Thanks 🙂

I'm surprised the windows are like a frying pan. I would have thought that the windows would let the light in which would then convert into heat inside the room which is causing the furnance like effect.

Is there a possibility of putting window shades on the outside?

Just draw the curtains in the rooms facing the sun, leaving the windows open. Then when the sun moves, open the curtains again.

Even in mobile homes in France, this is what you have to do. Its to do with the strength of the sun, not the windows. If it was ongoing, you might consider getting the reflective blinds. But by the looks of things, Friday is the end of the good weather.

That is also happening, once the sun hits the window the whole room heats up and gets very stuffy.

I was looking at putting some solution outside the window alright, when I was in the Netherlands they had external roller shutters on the windows which I thought was very smart.

Maybe get some cheap static cling window films to experiment with, and then consider a more permanent solution.

e.g. random Amazon result

French Shutters could be your solution.

In the same boat here - luckily enough im working from the other side of the house in the shade.

As mentioned - if you have curtain/blinds keep them closed with windows open while the sun is shining.

Would be reluctant myself to apply a permanent solution as its not something we have to deal with very often throughout the year.

Something like external film will reduce the actual benefit you get from solar gain in the colder months when the sun is shining.

And the price of installing shutters, internal/external, wouldnt merit the fact you will need to use them for a couple of weeks a year if you are lucky. (Unless you like the aesthetic of shutters, thats a different story)

Actually, odd as it may sound, pulling the curtains and keeping the windows shut is a better solution during the main heat of the day.

But you do need to darken the room to keep the sun out. I’m not even sure the triple glazing is the problem: I think single glazing would have the same effect except that when it cools down in the evening (unlike really hot places like Spanish cities where the nights are nearly as hot) the single glazing lets the heat back out again.

None of the windows have curtains just PVC Venetian blinds closing them stops the sun beaming on you but doesn’t stop the heat from coming into the room.

I going to order some window film and test it on the kitchen window which is south facing.

Perfect I’m going to order these and test. 🙂

The things you seen in Holland were probably these .... https://www.rolladenplanet.de/vorbaurollladen/rollladen-standardmasse/380/vorbaurollladen-alu-halbrund-37-mm-aussenrolladen?c=2152&gclid=EAIaIQobChMIkISE-sLx8QIV5O3mCh3i6gznEAYYASABEgJrlfD_BwE

Have been looking for a company in Ireland to install them in my own house, great if like me you do shift work and want to sleep during the day. Side effect is they keep the heat out in summer. Basically, security shutters you would see on shops, just made of light weight alu elements.

Mullaghteelin · 20-07-2021 11:24am

In places where temperatures climb well over 30C, I'ld imagine leaving the windows closed to keep the heat out is the lesser of two evils.

In Ireland, however, open windows is probably a better bet.

mrslancaster · 20-07-2021 11:42am

What about blackout blinds?

Oh very good but how you pull them down? The windows in Germany and Holland open inwards so you can put your hand out to pull them down.

We get maybe 3-4 weeks a year max of this heat and thats in a lucky year. Do you really need to invest in something for such a short period?

If you have windows at the front and window back then try opening both to create a wind tunnel to reduce heat might be an option

They could work but I think the solution would be something external to stop the heat from every come in, the roller blinds RedCardKid posted is what you want but you have to be careful making your house looking like fort knoxs or the local scumbag might think there is something nice inside.

Outkast_IRE · 20-07-2021 12:04pm

Dont get external blinds , they are really not required in this country and will look so out of place.

Close blinds on the sunny side during the day. If opening windows do it on two opposite sides of the house and leave the doors open and it will cross ventilate the space.

If you are really feeling the heat get some fans for inside or maybe splash out on the dyson hot/cold fan .

Triple glazing won't keep the heat out, unless you get speciality glass which isn't used in domestic situations here, but it'll definately keep whatever heat form the sun gets in.

https://boards.ie/discussion/comment/117636697#Comment_117636697

You want to stop the sun hitting the window so blocking the outside is better than the inside. I work nights and having the room completely dark during the day didn't make much difference to the heat.

A slip is cut into the wondow frame. A flat pully rope is run internally and it is used to pull them up. Gravity looks after letting them down once the rope is released.

That sounds a bit jankey as the Americans would say, do you have an example of how it looks like?

stevek93 · 21-07-2021 7:26am

I bought a infrared thermometer from Amazon the window is reading 35 to 40c in some places with the blinds shut, I am going to buy that window film and test again after applying.

Another interesting find is that the attic roof is almost 50c, I do have lots of wool insulation up there but I have purchased foil to cover the roof I tested a little patch already with some floor insulation I had and it made almost 20c surface difference I suppose this will also help during the winter.

Go to YouTube and search for the following: Vorbaurollladen einbauen / Rollladen einbauen - Montageanleitung

Sorry this morning I am not allowed to post links ...

Great job.

But they're not really something that you can build in as an afterthought.

Edit: Actually there are versions that can be built on at a later stage but it seems like a lot of effort.

If you're in Ireland then the hot weather will be gone in a few days, pull the curtains or blinds, normal service will soon be resumed.

It looks good, does Holland and Germany get longer warmer periods than us? If they don't I wonder why we don't have these. I might install these on the back of the house that is south facing, it is very warm in these rooms even when it is not 20+ degrees outside. I am not sure putting them on the front of the house it might look a bit weird I am a terraced house in the middle of a row of 7 houses, maybe if I was a house on its own land it might be okay or I shouldn't care and go ham 🙂

In Germany anyway it's much longer. Normally from May to September it's good and warm with a fortnight in July where it'll hit the mid-30s or so. That said, this year is a bit of an exception so far.

If it keeps up for the next few years, I will install these also on the front. Who know maybe I will start a trend 😁

fits · 21-07-2021 9:42am

I've often thought of installing some sort of brise soleil or maybe a retractable awning on my south facing windows. Not on priority list but hope to do sometime.

Tree · 21-07-2021 2:18pm

I'd love those shutters they do on the continent, but like, they get built in as the house is constructed, but they are so good. The ones in white with the little holes between the slats so you can let some light in during the day

They are not that bad to build in at a later date. It is a case of screwing the panels to the outside of the window / house walls. A drill with a round bit is then used to provide the hole for the pully cord. Had them on the house in Germany prior to returning 3 years ago, great things, something we miss.

I have exterior awnings on two of my south facing windows and would be lost without them, we get 12+ hours of sun onto the back of the house and ignoring the heat, the sun would bleach anything left inside the rooms!

stevek93 · 21-07-2021 7:00pm

A fabric awning?

GreeBo · 22-07-2021 9:58am

https://boards.ie/discussion/comment/117643630#Comment_117643630

Yep, they roll in and out as needed and when rolled up are "protected" within whats effectively a wooden box on the wall above the window.

I'll post a pic if I think of it next time

Find out the G value of the triple glazed windows. Value is 0 to 1 with nearer 0 being better to reject solar gain.

May need planning permission for external shutters

Brise soleil deals with summer radiation well but also may need planning to mount

There are films you can add to glass that cut down on solar gain but check with window supplier as may invalidate your warranty
