Xtratherm FR/BGM is Dual Application Flat Roof Insulation Board.
This means it has two usable surfaces to suit two different flat roof waterproofing systems.
The Darker Black side will suit most Bituminous Waterproofing Systems and Lighter Beige side will suit Fully Adhered Single Ply Membranes.
There are some issues and longer lead times currently with supplying Insulation boards, like many building products. We do have stock of certain boards and thicknesses in our depot available to purchase and more stock arriving each week. The stock availability is a fluid situation currently and we will always try and show a true reflection of what's available or not here in our online store. This is not always possible. If you would like a more accurate idea or simply would like to check lead times and stock then please do get in touch.
We can supply a wide range of insulation types from a variety of manufacturers and not all of these are displayed in our online store currently. We can offer larger discounts for bulk and direct to site prices. These are quite often the best ways to buy. So please do contact us for further information.
