We also have insulation boards suitable for more specialist roof applications for example inverted roof insulation and balcony insulation.
Inverted roof is very preferable as well.
Another key advantage of specifying a pitched roof is the ability to provide a very high level of thermal performance in these roof types whether you re looking to insulate at joist ceiling level for a cold pitched roof or at rafter level if a living area within a warm roof construction is desired.
This over rafter insulation method also reduces thermal bridging giving an airtight continuous layer of high performance insulation and results in a well insulated attic space.
Warm deck pitched roof the insulation is placed over the rafters and then a felt is placed on top.
