Warm Roof Insualtion


Postby highlandbee » Thu Feb 23, 2012 2:00 pm

is it possible to use EPS 70 polystyrene insulation in a warm flat roof, with timber deck. If so what thickness would be needed to achieve a U value to satisy building control, or is PIR rigid insulation the only option. Also can edpm be layed on top of this, or wpould anpother ;layer of plywood be needed?

ask the maufacturers if their product can be used in this application, speak to their technical department. they may require a sketch of teh detail to help them answer your questions.

Hi I'm new to the site :-)

King span supply a insulated board which comes with a plywood surface so it's ready for rubber or felt to be applied. If your interested I can put you in touch with my suppliers.
