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 ?

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.
