So we can maintain a comfortable working environment upstairs we need to do some work to insulate the area.
This falls into two categories
a) Seal the roof Apex to stop heat escaping, and rain coming in
b) Stop heat loss through the windows.
Please give your ideas.
My idea to start is, Hire a Worktower to reach the Apex for sealing with expanding foam, No-Nail battons to the down frames on the windows, Insulated top half of windows with Spaceblanket, and the lower half with Polycarb.
Thoughts please
