Why the UK glass mineral wool insulation manufacturer is the perfect partner for offsite construction…

Reliability and innovation matter in the offsite sector. Now, more than ever.

Modern methods of construction (MMC) are still treated with some hesitancy – despite the enormous benefits they can provide. However, offsite construction will be crucial if the UK government is going to get close to meeting its 1.5m housebuilding target in the coming years.

In a time of both challenge and opportunity for offsite manufacturers, it is more crucial than ever to have dependable partners and suppliers on your side: companies that deliver quality products and service, every time.

This dependability is one of the core reasons why glass mineral wool insulation manufacturer, Superglass, is gaining such a strong reputation across the offsite industry. Following acquisition in 2023, Superglass is now part of international building materials manufacturer, Etex, meaning it has access to a truly global team with decades of experience and pioneering research and development facilities.

However, what truly sets Superglass apart is the way in which the firm uses “glass science” in the development of its products. The firm’s manufacturing facility in Stirling, Scotland is one of Europe’s most advanced and draws on continually evolving glass science. The firm uses lean production techniques to develop insulation products which are not only adaptable for various applications but also minimise waste in the process.

Recently, Superglass became the first UK insulation manufacturer to have achieved the Code for Construction Product Information (CCPI) assessment for the majority of its product sets including: Loft Insulation, Acoustic Insulation, Cladding Insulation, Timber and Rafter Insulation, Superwall Cavity Batts and Blown Wool Insulation. This assessment is increasingly important to specifiers and buyers looking for guarantees and safeguards in product performance claims.

All Superglass thermal and acoustic products are deemed non-combustible with a fire classification of Euroclass A1, which is the highest possible rating, when tested to BS EN 13501-1:2018 Reaction to Fire.

Along with providing products that support offsite construction companies in complying with ever-evolving regulations, contributing to a more sustainable built environment is one of Superglass’ biggest commitments. Over its lifetime, its glass mineral wool insulation can typically save more than 200 times the energy used in its creation and transportation.

Superglass insulation is also made from up to 84% recycled glass and in 2024, the manufacturer recycled around 33,000 tonnes of waste glass to make its products. Superglass products also have a Generic BRE Green Guide rating of A+ and contain no ozone-depleting substances or greenhouse gases.

The manufacturer recently announced further efforts to support the wider sector’s sustainability efforts as well as its own, after scrapping white pallets from its supply chain by becoming an early adopter of the recovery, repair and reuse scheme, The Pallet LOOP. From April 2025, all Superglass cured glass mineral wool insulation products are being distributed on The Pallet LOOP’s distinctive green pallets, which are designed to be collected and put back into the building materials supply chain.

All Superglass products also benefit from compression packaging to reduce the insulation to up to one ninth of its original volume, so more can be loaded onto each delivery – reducing the number of trucks on the road and as a result delivery miles and carbon emissions.

All of this considered, Superglass – with its glass science approach – is proving to be the intelligent choice of insulation partner for offsite manufacturers. In times of transformation and great opportunity, there is no better reassurance than having a forward-thinking, dependable partner by your side.
