Product Information

Fibreglass Wool Blanket is manufactured from a mat of glasswool bonded with a thermosetting resin, forming a lightweight and flexible insulation material. Apart from providing good thermal insulation qualities, it is also an effective sound absorption materal.

Common Applications

Fibreglass Wool Blanket is commonly used for the underside of metal roofing in industrial projects for insulation purposes. It can also be extensively used for all types of residential and commercial projects. The glasswool can either be installed between the roof trusses or just above the ceiling. Single sided or double sided aluminium foil has to be placed below the glasswool blanket for vapour barrier application.
