Customer Questions
Do I need a professional to install my new loft roll?
You may decide to hire a professional to install your new loft roll insulation, however a competent DIY'er should be able to complete the work. We advise looking at installation guides and ensuring you have everything needed before beginning the work.
Some of my loft roll has got wet, can I still use it?
If the loft roll gets wet it will not reduce the insulating performance of the product. The affected material should be seperated and placed in a warm ventilated area to allow it to dry out naturally before installing. If the product has been wet for a long time it is possible mould has grown, and in that case the material should be replaced.
I need a roll at 600mm width for my loft joists. Is there a roll that is 600mm wide?
The Isover Spacesaver loft rolls are pre cut at 600mm centres making it an ideal product to be used.
Is it eco-friendly?
Isover is a glasswool product and the majority of raw materials used are recycled glass bottles.
