Glass Wool Insulation

The versatile glass wool insulation enhances acoustic and thermal comfort in interior spaces cost-effectively. It is one of the most popular types of mineral-based insulation used in homes and commercial buildings, thanks to its excellent performance-to-cost ratio.

What is glass wool?

Glass wool is sometimes referred to as fibreglass wool or glass insulation wool roll. It is made by melting glass (mostly recycled) and spinning it into soft, interwoven strands. These strands trap air within tiny pockets, forming an insulating layer that slows down heat transfer. Glass wool products have excellent flexibility, fire resistance, and acoustic control.

What is glass wool used for?

There are various construction applications where the use of glass wool is appropriate:

• Lofts and attics: Ideal for laying between joists or rafters.
• Walls: Installed in drylining systems, stud partitions, and cavity walls.
• Ceilings and floors: Minimises heat loss and noise transfer between levels.
• HVAC and duct systems: Helps improve efficient energy utilisation and acoustic control.
• Pipe insulation: For ducts and pipework in mechanical systems.
