Why Glass Mineral Wool Insulation?

There are plenty of insulation products on the market. When researching insulation solutions, you may have come across rigid foam (e.g. EPS or PIR boards), spray foam, sheep’s wool and rock mineral wool.

At Superglass, we believe glass mineral wool gives the best combination of performance and sustainability. Here’s why…

Superior Performance

Glass mineral wool has excellent thermal and acoustic performance, keeping your building warm and helping limit noise transfer between rooms and adjoining buildings. It’s also breathable, which helps to reduce the risk of condensation inside the building.

Poorly-fitted insulation has been found to be a key contributor to the energy performance gap in many buildings. Because of its flexibility, it’s easier to get a precise fit with glass mineral wool than other types of insulation, eliminating air gaps to make sure your building performs as it’s designed to.

Fire Protection

Superglass insulation has an A1 Reaction to Fire Classification – the highest possible fire rating. It’s literally classed as “non-combustible”.

The Grenfell Tower tragedy in 2017 shone a spotlight on the use of combustible materials when refurbishing existing buildings. At the end of last year, the government amended Building Regulations to require any materials used in the external walls of residential buildings taller than 18 metres to have a European Classification of Class A1 or Class A2.

We believe fire safety in any building is of paramount importance, which is why we’ve designed our insulation to have an A1 rating. Superglass insulation not only keeps your home snug and warm – it keeps it safe as well.

Environmental Sustainability

Our environmental ethos underpins everything we do. Glass mineral wool is both an excellent insulator, reducing carbon emissions from buildings, and an environmentally-friendly building material.

  • Superglass insulation contains up to 84% recycled glass
  • Glass mineral wool has zero Ozone Depletion Potential and Global Warming Potential, i.e. it doesn’t harm the ozone layer
  • We’ve developed our manufacturing process to use less energy in production
  • We recycle our aqueous and fibre waste so it doesn’t go into the sewer or to landfill
  • Our insulation is compression-packed to help reduce packaging waste and transport costs

We’re proud that our glass mineral wool insulation has a BRE Green Guide rating of A+, meaning it has the lowest possible environmental impact.
