NOVAtherm Insulation for Ceilings

Standard Product Range and Pricing

Ceiling Insulation

The product is supplied in rolls, (long blankets) of 435mm and 870mm to suit your ceiling construction and vacuum-packaged to reduce volume (and therefore shipping costs). Due to vacuum packing, the loft (thickness) on unpacking is less than the fully recovered loft. Full loft recovery will take place over 14 -60 days. As the fibres relax out of compression the product lofts up (this is particularly marked once the product is installed, as warmth helps the process).
