What Glava does

Glava AS is Norway's largest producer of insulation products, founded in 1935 and headquartered in Askim, where its manufacturing facility is also located. The company manufactures glass wool insulation (plates, rolls, and blown insulation) for thermal, acoustic, and fire protection applications in residential and commercial buildings, incorporating up to 70-80% recycled glass in its products. Its portfolio spans standard (Glava Proff 34), premium (Glava Extrem 32), and budget (Glava Økonomi 38) glass wool lines, facade systems (Glava Veggplate 31, Glava Driv, Glava Front), the Glava Pluss System for continuous exterior insulation, and acoustic and sealing accessories; Glavatech, a dedicated innovation unit (converted in 2017 from Bolig Enøk AS), drives new system development including the patented Glava Front retrofit facade element.

The company sells primarily via project sales and advisory relationships with Norwegian builders, contractors, craftsmen, project developers, and homeowners, supported by category-segmented phone lines (building insulation, technical insulation, acoustics/ceilings, compact roofs), a login-gated e-commerce portal, and technical content such as calculation tools and construction guidance. Glava cross-sells complementary Saint-Gobain sister brands (Weber, Gyproc, Ecophon) through the same delivery channel on large projects and also serves marine and offshore insulation use cases.

Glava AS is a privately held Norwegian entity and a subsidiary of Saint-Gobain Construction Materials Norway (part of Euronext-listed Saint-Gobain). It maintains ISO 9001 and ISO 14001 certifications, holds EPDs and BREEAM NOR compliance documentation across product lines, and operates Glava Returordning, a glass wool recycling program with partners including Stena Recycling Moss, Norsk Gjenvinning, Franzefoss, and Ragnsells.

Core offering

Glava manufactures and sells glass wool insulation products — including plates, rolls, blown insulation, vapor and wind barriers, and accessory components — together with proprietary facade and retrofit systems (Glava Pluss System, Glava Driv, Glava Front) for residential, commercial, and technical insulation applications in the Norwegian construction market. The company also operates a glass wool return and recycling program (Glava Returordning) through partner waste-handling firms.

Glava is Norway's largest insulation products manufacturer and part of Saint-Gobain. The product portfolio centers on glass wool insulation solutions for buildings and construction, including standard products (Glava Proff 34, Glava Extrem 32, Glava Økonomi 38), facade systems (Glava Driv, Glava Front, Glava Veggplate 31), and the Glava Pluss System (innovative stud system with stuck glass wool and laminated timber). Supporting products include sealing solutions (Glava Bastion Vindsperre wind barriers, Glava Dampsperre vapor barriers), acoustic products (Glava Trinnlydplate, Glava Lydreduksjonsbøyle), blown insulation (Glava Blåseull, ISOVER Insulsafe), and specialty items (winter mats, cutting boards). The company also operates Glavatech, its innovation division developing new solutions like the Glava Front facade element system for energy-efficient retrofitting. Complementary brands under Saint-Gobain Norway include Gyproc (drywall) and Weber (mortar systems). Glava products contain up to 80% recycled glass and the company runs a glass wool recycling program (Glava Returordning) for construction site waste.

• Glavatech: Innovation department of Glava that tests and develops new products and solutions for the construction industry.

Products and services

• Glava Proff 34 (Plate and Roll) Standard glass wool insulation plate and roll, the company's flagship core product offering good thermal, fire (Euroclass A1 non-combustible), and acoustic insulation. Made with up to 70% recycled glass. Available in multiple thicknesses and dimensions.
• Glava Extrem 32 Plate Premium glass wool insulation plate with 6% better insulation performance than Proff 34, targeted at demanding climate constructions, floors, walls, and roofs. Available in widths adapted to 48mm and 36mm timber framing.
• Glava Økonomi 38 Plate Budget glass wool insulation plate for thermal, sound, and fire insulation. Class A1 non-combustible. Used primarily for interior walls and floor separations where demanding thermal performance is not required.
• Glava Veggplate 31 Compact glass wool plate adapted for mounting on the exterior side of external walls. Available in three thicknesses (48, 68, 98 mm). Minimizes overall wall thickness, reduces thermal bridges, and improves U-values compared to traditional framing-on solutions.
• Glava Pluss System External wall insulation system using studs made of stitched glass wool with laminated timber. Provides continuous exterior insulation and minimizes thermal bridges. Suitable for both new builds and rehabilitation, on concrete, brick, aerated concrete, CLT (massivtre), and timber frame structures.
• Glava Driv Facade System Ventilated facade system for rapid and efficient insulation. Made with water-repellent stitched glass wool and aluminum profiles, consisting of only four components. Installable both horizontally and vertically, suitable for new builds and retrofit projects.
• Glava Front Facade Element Patented element-based facade system for rapid and affordable thermal envelope upgrades of existing buildings. Developed by Glavatech with support from Innovasjon Norge and Enova. Elements are 60x120cm and weigh approximately 11 kg, designed for handling by a single craftsman.
• Glava Blåseull (Blown Insulation) Blowing wool for cavity insulation and renovation projects where traditional insulation methods cannot be applied, such as difficult-to-access areas.
• Glava Returordning (Glass Wool Recycling Service) Construction-site return and recycling program for glass wool waste. Operated in partnership with Stena Recycling Moss, Norsk Gjenvinning, Franzefoss, and Ragnsells. Waste glass wool is processed into foam glass (skumglass) used as a raw material replacement, supporting a circular economy for insulation.
• Glava Sealing and Acoustic Products Standalone sealing and acoustic accessory line including the Glava Bastion Vindsperre wind barrier (prevents wind penetration into the insulated layer and protects against driving rain), Glava Dampsperre vapor barrier (provides internal air tightness on the warm side of insulation), Glava Trinnlydplate impact sound plate (reduces impact sound transmission between floors), and Glava Lydreduksjonsbøyle sound reduction bracket.
