Glass Wool Insulation

Glass wool insulation is a fibrous thermal and acoustic material made from recycled glass. It traps air to slow heat loss and reduce noise between rooms and floors. Builders, loft converters and DIYers use it to improve comfort and cut energy bills.

Our range includes rolls and cut slabs in common thicknesses for timber and metal stud walls, lofts and ceilings. You’ll also find accessories like support wires and edge tapes to help fitting. These products suit new builds and retrofit projects alike.

Fit glass wool to keep heat where you want it and lower heating costs. It also dampens sound from footsteps and voices between spaces. Choose the right thickness and size to match your cavity or joist spacing for best performance.
