Hi,
I'm looking into re-insulating and boarding my loft floor. After getting a few quotes I've decided to save some money and do it myself.
The joists in my loft are only 100mm high, so I thought about using 100mm Glass Mineral Wool insulation and covering that with some Aluminium Foil insulation type stuff and finally boarding over the entire lot.
So I went up earlier today to have a look under the existing flooring and noticed that the gap between the joists is inconsistent. I measure 4 different gaps and they ranged from 370mm to 420mm.
So my 2 questions are;
1) How sound is my plan of using 100mm Glass Mineral Wool insulation with Aluminium Foil insulation on top all boarded over?
2) How to I get a roll of insulation that is 400mm wide to fit snugly in those varied width gaps? I don't really want to trim long rolls of insulation.
Any help is greatly appreciated.
Thanks.
