Rockwool Insulation - Glasswool Insulation

Apart from being an excellent thermal insulation material, rock wool is a suitable material to prevent noise and fire.

Glasswool is primarily made from recycled glass. The glass is melted in a furnace then sent to a spinner to create fibres. The glasswool fibres create millions of tiny air pockets which trap the air. The air pockets make glasswool a poor conductor of heat, an important requirement of effective insulation batts.
