Under Floor Insulation Victoria from Askin Performance Panels

RETROTHERM® is available in 50 and 75mm thickness recycled polystyrene measuring 1.2m long. Width variations from 420mm to 600mm suit all stud and floor joist applications, the special 'concertina edges' compress on application to ensure that insulation is a snug fit between floor joists.

Polystyrene contains 98% air by volume in a closed cell structure and this makes it a very efficient insulation product with an R value from 1.2 to 2.7 The problem with traditional sub-floor products is that they can be affected by draughts and breezes. An added advantage of RETROTHERM® is that the thermal resistance (Rvalue) is considerably more stable when subjected to air movements.

The "one size fits all" profile and special 'concertina edges' on RETROTHERM® allows you to simply cut or snap off the side pieces of the panel to ensure a nice snug fit between the floor joists of your home. RETROTHERM® can be glued in place using the specialist water based adhesive or mechanically fixed using galvanized nails or folded galv. sheet.
