next year we will be having a new loft conversion done to our home. i want to get the builder to "completely " remove absolutley everything of the existing roof trusses etc. as it is a 1930's semi. and we wonna start afresh.
does anyone know if after fitting new trusses, ply sheeting can be used to board up all of the new roof before battening up and tiling. i know the yanks and canadians do so in their properties.
apart from the additional weight added to the strusses are their any other disadvantages?.... i wonna do this as i am thinking of adding spray foam insulation on the inner side of the trusses and don't wonna spray directly onto the membrane/battens/tiles. and also because the plywood will give it better draught proofing and a nice plane on which to work the spray foam on. any advice will be much appreciated.
