Internal Windows Reveal Insulation

bonizilla

Hello everyone, I'm doing a DIY project at home, Insulating internaly my kids room.

For the walls I am using insulated plasterboard 12mm+60mm - 72mm, but now

I am in doubt which material I can use for the window reveals. I cannot find like 15mm insulated plasterboard.

Is there anyone who has experience and could give me advice which material I could use and find it in Dublin?

Can I use this boards Gyproc Wallboard Plasterboard 2438mm x 1200mm x 12.5mm Tapered Edge?

Tks

Yes, sure. This is it:

But try to get the deepest thickness into the reveal. Also consider using air-tight tape too so that the frame is masked off.

Example:

Look-up the method of applying it to the whole reveal.

Questions, ask away!

You mean, use both? Tapping before and then lay insulated plasterboard?

Yes, correct. The air-tight tape stops air movement around the reveal (all common blocks are air permeable) and it helps to resolve some of the common issues with the joints between double-leaf walls, internal insulation and window reveals (ie - massive air gaps). It will also be a much better job overall.
