The Fire Safety Benefits of Superglass Insulation 

In any building, fire safety is of paramount importance. It’s crucial that architects, specifiers and installers know how the insulation they put into a building will behave in the event of a fire. And even more important that occupants can be sure their building has the best safety measures built in from the outset.

Superglass, as a glass mineral wool, offers highly effective thermal insulation with the reassurance of being truly fire safe – and it’s been thoroughly tested to prove the levels of fire protection it offers. 

No insulation has a higher fire rating than Superglass

All Superglass products have a Euroclass A1 fire classification – the highest possible rating – so are classed as some of the safest materials on the market. Our insulation is made from waste glass, an inert, inorganic and non-combustible material. This can help protect buildings against fire by not supporting the spread of flames therefore helping to protect the building, thus limiting damage and protecting its occupants.

Keeps homes warmer, doesn’t contribute to the spread of fire

The primary purpose of insulation of course, is to retain the heat in a building and reduce the amount of energy needed to keep it at a comfortable temperature. As non-combustible glass mineral wool insulation though, Superglass offers an extremely important secondary benefit – effectively adding a layer of fire protection to buildings, which means that a building with Superglass insulation will have an improved fire rating.

Tested for total reassurance

Superglass insulation has undergone the strictest independent testing to BS EN 13501-1 Reaction to Fire standards. This follows the industry-standard Euroclass system, which classifies the reaction to fire of a building material with ratings of A1, A2, B, C, D, E and F. A1 and A2 ratings mean a material does not burn or contribute to the spread of flames or emit any significant levels of toxic smoke in a fire, while materials rated B to F are combustible. 

Glass Mineral Wool as the preferred form of insulation

At Superglass, we’re driven to create insulation that’s sustainable for the long term. To us, that means creating a practical, long-lasting product that will keep buildings warm for decades using recycled materials.

Glass wool insulation is designed for superior thermal comfort, easily meeting the low U-values required by building regulations. But it’s not just about ticking a box. We make sure our insulation works just as well in practice as it does on paper.

Glass wool is flexible, allowing it to fit snugly against uneven surfaces, leaving no gaps for heat to escape through.

Our ’made to measure’ rolls and slabs are designed to fit between standard wall ties, joists or timber stud spacings, reducing waste and making installation easy.
