What Gorter Group B.V. does
Gorter Group B.V. is a Dutch building-components manufacturer founded in 1928 and headquartered in Schagen, Netherlands, specializing in aluminium roof hatches and complementary floor, wall, and ceiling access doors. Its core product portfolio centers on a six-variant roof hatch lineup — RHT (standard, thermally separated), RHTG (glazed), RHTEI (fire-rated, EI-60/EI-120), RHTEP (passive-house insulation, Uw ≤ 0.198 W/(m²·K)), RHTX (explosion vent), and RHTS (integrated scissor stair, A++) — together with floor doors (WA, WAPT, WAEI, WAG, OP), wall/ceiling doors, and access accessories (ladders, scissor stairs, fixed stairs, electric operation). The technical platform rests on two patented innovations: a fully thermally broken curb/cover construction (Patent no. 2519072) and a scissor stair extension system (Dutch Patent no. 2000298), with thermal performance third-party verified by EuroSolid per ISO 10077-1/2 and fire/safety certifications issued by SKG-IKOB, TÜV NORD, KOMO, Aboma, Efectis, and ISO 9001.
The company operates a strict B2B distribution model, selling directly to architects, contractors, and construction companies (and explicitly not to consumers), supported by a digital quote-request configurator, a content-dense architects portal with BIM/Revit/Autodesk/SketchUp libraries, and a network of local offices worldwide — most recently a wholly-owned UK subsidiary (Gorter Roof Hatches Ltd., Birmingham). Pricing is unit-based, with standard roof hatches ranging from approximately €1,000 to €9,000 depending on size and option set; UK GBP pricing is published separately. Revenue is generated entirely through one-time unit sales and accessories, with no subscription, licensing, or recurring component disclosed. The company employs 101–250 staff and serves verticals including commercial real estate, healthcare, education, government, sports/stadium, hospitality, automotive R&D, technology campuses, and historic preservation — evidenced by reference installations on the Burj Khalifa, Booking.com HQ, NHS Community Diagnostic Centre Hull, MIRA Technology Park, Mulberry Academy London Dock (Passivhaus), Oval Village London, Oriel College Oxford, and Taymouth Castle Scotland.
Gorter is privately held with no disclosed funding rounds, institutional investors, or parent company; ownership commentary indicates continuous independent operation since 1928. The business is active and operating, with a maintained website, current product/news cycle, and recent UK subsidiary formation in 2026 representing the principal recent corporate structural move.
