What Glidevale does

Glidevale Protect is a UK-based manufacturer of building fabric products serving the construction industry across the United Kingdom and Ireland. Founded in 1988 and headquartered in Sale, Greater Manchester, the company operates as a trading brand of Wienerberger Ltd — the UK subsidiary of Vienna-listed Wienerberger AG — alongside sister brands Passivent, Kingfisher Louvres, and Building Product Design. The business is organized into two divisions: a Roofing Division (roofing ventilation, underlays, accessories, and solar-compatible membranes) and a Construction Division (airtightness solutions, breather membranes, fire rated wall membranes, building ventilation, and cavity trays). The portfolio is positioned as a 'whole house' single-source solution addressing ventilation, airtightness, condensation control, thermal efficiency, damp proofing, and fire safety across new-build and refurbishment schemes.

The company's products are certified to ISO 9001 (quality), ISO 14001 (environmental) and ISO 45001 (health and safety) standards, and its fire rated membranes are independently tested to exceed UK Building Regulations Approved Document Part B and Irish Technical Guidance Document B for buildings above 11m and 18m. Glidevale Protect holds Structural Timber Association Assure Gold Level status and is a member of the ITFMA, MPBA, Offsite Alliance and NFRC, positioning it across traditional housebuilding, offsite/modular construction, social housing, and roofing contractor channels. Technical support services — including CPD seminars, U-value calculations, condensation risk analysis, and site take-offs — are provided at no extra cost to support specification-led sales.

The revenue model is B2B hardware sales of building envelope components, distributed via direct website enquiries, phone, and email sales channels targeting enterprise buyers (housebuilders, offsite manufacturers, social housing providers, specifiers, and contractors). Pricing is quote-based and not publicly disclosed. Customer acquisition is sales-led and reinforced through content marketing, technical resources (NBS and BIMSTORE specifications, downloads), case studies, YouTube product videos, LinkedIn, and CPD seminars aimed at construction industry professionals. No revenue, headcount, or funding figures are disclosed at the brand level.

Scale indicators1 record

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Saint-Gobain: Global building materials giant offering membranes, insulation, glazing and roofing systems through brands including Isover and Weber. Operates at vastly larger scale and competes with Glidevale across multiple building envelope categories.
• Knauf Insulation: Global manufacturer of insulation and building envelope systems. Overlaps with Glidevale in the wider building fabric category — particularly around thermal efficiency, fire performance and airtightness — though insulation is the primary product.
• Kingspan Group: Ireland-headquartered global building envelope solutions provider with insulation, membranes, roofing and daylighting products. Comparable as a building-fabric solutions peer but operates at significantly larger scale and broader geographic scope.
• ROCKWOOL: Global manufacturer of stone wool insulation and building envelope solutions. Comparable as a broad building fabric competitor, particularly where insulation interacts with fire safety and airtightness — though ROCKWOOL's core is insulation rather than membranes.

Direct peers

• Polypipe (Genuit Group): UK manufacturer of ventilation, drainage and plumbing systems for the construction sector. Direct overlap with Glidevale's building and roofing ventilation product lines and similar UK housebuilder/social housing customer base.
• DuPont Tyvek: Manufacturer of Tyvek breather membranes and building envelope solutions widely used in UK and European construction. Direct product competitor to Glidevale's breather membranes and airtightness solutions, with a global brand presence.
• Actis: Manufacturer of reflective insulation, breather membranes and vapour control layers for the UK and European construction markets. Direct product overlap with Glidevale's membranes and thermal efficiency categories.
• A. Proctor Group: UK-based manufacturer of building membranes, insulation and roofing underlays for the construction industry. Closely comparable to Glidevale Protect in product categories (breather membranes, roofing underlays, airtightness and condensation control) and UK/Ireland customer base.

Regional players

• BMI Group: Major flat and pitched roofing systems manufacturer serving the UK and European markets. Comparable through Glidevale's Roofing Division products (roofing underlays, ventilation and accessories), though BMI is significantly larger and more focused on roof systems integration.
• SIG plc: UK-listed specialist distributor of building products including membranes, insulation, roofing and interior fit-out. Comparable through overlapping product range and customer base, though operates as a distributor rather than manufacturer.
