Superglass

What Superglass does

Superglass Insulation Limited, founded in 1987 and headquartered in Stirling, Scotland, is one of the UK's leading manufacturers of glass mineral wool insulation, producing cured products (rolls, slabs, batts) and blown wool insulation from up to 84% recycled glass. Its products deliver thermal, acoustic, and non-combustible (Euroclass A1) performance for roofs, external walls, floors, and party/separating wall applications, and are differentiated by its proprietary THINKTECH glass chemistry and fiber science platform, manufactured at what the company describes as one of Europe's most advanced production facilities. The company holds a broad certification stack including BBA, CCPI (on the majority of product sets), UKCA/CE, EUCEB, ISO 9001/14001, and a BRE Green Guide A+ rating, and supports the specification chain through NBS Source, NBS BIM, U-value and Psi-value calculators, and a THINKTECH mobile app that records geo/time-stamped installation data and issues 10-year warranties on blown wool installations.

Superglass generates revenue by selling insulation products exclusively through a nationwide network of builders' merchants and distributors — not directly to end customers — with no public pricing disclosed. Its customers span housebuilders, professional installers, architects/specifiers, merchants and distributors (all primary segments), and homeowners (secondary), served through a multi-channel GTM that combines a specification/sales-led approach (NBS, CPD, Technical Services Team, Business Development Managers) with consumer-facing content (Knowledge Hub, brand film, homeowner hub). Pricing follows a pay-as-you-go, merchant-determined model. Since 2023, Superglass has been wholly owned by Etex, the Belgian building materials group, operating as a market area within Etex's Insulation division alongside URSA, and contributing to a UK position that represented approximately 15% of Etex group revenue in 2022.

Direct peers

• Knauf Insulation: One of the world's largest manufacturers of glass and rock mineral wool insulation, with major UK manufacturing operations. Directly competes with Superglass in glass mineral wool rolls, batts, and blown wool across UK and Irish merchants.
• Saint-Gobain Isover: Saint-Gobain's glass mineral wool insulation brand with significant UK market share. Competes head-to-head with Superglass in cavity batts, loft rolls, and acoustic insulation for housebuilders and merchants.
• Rockwool: Global leader in stone wool insulation with strong UK presence. Directly competes in non-combustible insulation for residential and commercial buildings, overlapping Superglass's key specification segments.
• Recticel Insulation: European manufacturer of PIR and PUR rigid insulation with UK distribution. Competes in commercial and residential insulation segments where Superglass glass mineral wool is specified as an alternative.
• Celotex: Saint-Gobain-owned PIR insulation manufacturer competing with Superglass in UK pitched roof, wall, and floor insulation markets — particularly relevant given overlapping UK merchant channels.
• URSA: Sister brand within Etex's Insulation division, also manufacturing mineral wool insulation across continental Europe. Closest comparable by product mix (glass and stone wool), customer type (builders' merchants, housebuilders), and parent-group integration model.

Broad incumbents

• Johns Manville: Berkshire Hathaway-owned manufacturer of fiberglass insulation and engineered products. Comparable technology base (glass mineral wool) and end-market exposure, though with a more industrial and North American weighting.
• Owens Corning: Global fiberglass insulation leader with significant UK presence. Overlaps with Superglass in glass wool technology and serves similar commercial and residential insulation end markets.
• Kingspan Insulation: UK and Ireland leader in rigid PIR/PUR insulation with growing mineral wool portfolio. Competes with Superglass in high-performance building envelope applications, particularly for housebuilders seeking thinner assemblies.

Emerging players

• Armacell: Global manufacturer of flexible elastomeric foams and engineered foams for equipment insulation. Adjacent to Superglass in building and HVAC insulation applications, though more focused on technical/industrial segments.
