Re: Parent's chalet bungalow - insulation plan.

Thanks for the suggestion. It looks as though RWA45 is available only in 600mm widths. As my joists are 370mm apart this is no good. Are there any specific types of material that would be suitable for that area? Is the density of the material relevant? I am considering PIR board with Gapo-Tape for t...

Re: Parent's chalet bungalow - insulation plan.

Parent's chalet bungalow - insulation plan.

Hello, I am looking to better insulate my parent’s 1970’s chalet bungalow as the upstairs is noticeably warmer than the downstairs. The upstairs also gets very hot in summer and cold at night and the living room downstairs can be very cold in the winter. The living room has large windows and two and...
