Glass wool: the high performing insulation

Glass wool insulation

Glass wool is an insulating material made from fibres of glass arranged using a binder into a texture similar to wool. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties.

Why choose Glass Wool ?

Glass wool products are non-combustible and positioned for operating temperatures up to 350°C.

It is made of 80% recyclable materials

Is poses no health hazards

It is lightweight and easy to install

Glass wool will not promote mold growth or vermin infestation

It is non-corrosive to metal
