During our renovations we insulated all the walls; internal and external.
The external walls we insulated to keep heat in
and the internal walls we insulated to help soundproof them.
Our house is brick so there is a big gap between the frame and the bricks.
This gaps makes insulating the external walls difficult
as the insulation would just fall out.
Solution: Staple a sheet of plastic (great recycling) to the wooden frame.
Then add your insulation; it’ll stay put for years to come.
