Glass Mineral Wool Insulation

Glass mineral wool is central to every Superglass product due its combination of thermal and acoustic performance, as well as being non-combustible.

Our glass mineral wool insulation is also made from up to 84% recycled glass, including windows, bottles and jars. We combine this with various other raw materials, then melt the mixture in a furnace. The molten glass is spun into millions of fine fibres, which are then formed into cured or blown products.

Cured glass mineral wool insulation – The fibres are bonded with resin binder to create a mat. This mat is ‘cured’ in an oven, cut to size, and packaged as rolls, slabs or batts.

Blown glass mineral wool insulation – Produced similarly to cured glass mineral wool, but remains uncured, making it a loose-fill product that can be ‘blown’ into various applications.

Glass mineral wool insulation offers ‘4-benefits-in-one’ that meet the increasing demand of thermal, fire, acoustic and environmental performance in the built environment.

Thermal Insulation

Glass mineral wool insulates by trapping and holding air within its fibres, enhancing comfort for building occupants by keeping it warmer in winter and cooler in summer. The greater the temperature difference between the inside and outside of a building, the faster it will lose heat in winter and gain heat in summer. Our glass mineral wool solutions help maintain a stable internal temperature by reducing heat transfer through convection, conduction, and radiation.

Acoustic Insulation

Glass mineral wool insulation works by absorbing and dampening sound waves, which helps reduce sound transmission through walls, floors and ceilings. This helps create a better internal environment for building occupants.

Fire Classification

All Superglass products are deemed non-combustible with a fire classification of Euroclass A1 (the highest possible rating) when tested to BS EN 13501-1 Reaction to Fire.

Environmental Performance

Superglass glass mineral wool is made from up to 84% recycled waste glass and contains no ozone-depleting substances or greenhouse gases, helping to achieve a generic BRE Green Guide rating of A+.

Our products also benefit from the latest compression packaging to reduce the highly flexible insulation up to one ninth of its original volume. This helps to maximise storage during distribution and reduce transport miles with more pallets per load.

Customer Service

Not only do we have a comprehensive product range and leading-edge manufacturing in place but, by forging close relationships with a nationwide network of merchants and distributors, we can deliver so much more. Our partnerships with our supply chain are key to providing a one-to-one level of service to specifiers and end users, a package that’s constantly reviewed and improved to meet their changing needs.
