Blotting the Sun Out of Windows

[Spinny]

Need to temporarily stop the solar gain throught my bifolds to keep the temperature of the floor down while LVT is laid.

 

Looking at window film ? Wouldn't it best to put this on the outside though ? Silver side outwards ?

[marmic]

anything to reflect will probably help and yes outside  - but better to stop sun hitting glass at all.   Brise soleil can take many forms. if only temporary a cheap gazebo outside maybe?  but may be worth looking at something more permanent if solar gain in these heatwaves is an issue.

An option (not saying it's good) is silver foil. Mist spray the glass with water from a sprayer and it will stick perfectly. Just make sure you don't scratch anything.

What about using radiator foil/insulation such as this ?

(I think any permanent solution will mean looking up what glass we had in the bifolds and rooflights. I thought it was UV limiting but really can't remember. We havn't got our electric roller blinds in yet and not sure how much effect they will have.)

If it’s just temporary then an old sheet will do, anything that will stop the sun hitting the glass will do. 
 

Long term, the sheet is probably not the best option.

Indeed, although we did have thoughts about putting hooks into the overhang fascia and having a triangular shade sail.

Might be a pain if a wind gets up though ?

[Russdl]

If you make it easily put up-able and take down-able it shouldn’t be a massive issue. Big heat (strong sun) normally coincides with high pressure which normally coincides with slack wind. 
 

At least that used to be the norm.

just put some cheap car sun shades on windows (from halfords - cheaper than amazon etc!)  - temporary measure until we decide how to build brise soleil.  not going to block it completely but should make some difference.  if they stay up!

A chuffing tarpaulin.

 

There, I said it.

 

Have the installers asked you to do this?

Whatever you do it's better to do it outside the glazing. 

 

I've heard story of sealed glazing units cracking when they are blocked on the inside.
