Isowool Spacesaver Insulation From Greengates Builders Merchants Accrington, Lancashire

What is Isowool Spacesaver Loft Insulation: 


The basic constituent of Isowool is glass mineral wool, manufactured from silica sand, the Earth's most abundant naturally occurring mineral.

Glass mineral wool is one of the most envi­ron­men­tally friendly insulation materials. Inorganic and completely inert, over 70% of the raw material used in the production cycle are recycled.

This process does not include the use of CFC's, HCFC's or any other envi­ron­men­tally damaging gases.


Isowool Spacesaver is a high quality thermal and acoustic insulating mat in roll form, perforated along the roll to allow the user to use full, half or third width options in roof spaces. Glass mineral wool insulation rolls suitable for providing thermal and acoustic insulation in domestic-type pitched roofs.
