Ramenfabriek op 't Hoog

What Ramenfabriek op 't Hoog does

Ramenfabriek op 't Hoog is a Dutch family-owned manufacturer of PVC, aluminium, and steel-look window frames and doors, headquartered in Moergestel, Netherlands, and founded in 1986 by Jan Op 't Hoog. The company operates an in-house factory producing Kunststof frames (calcium-zinc stabilized German PVC profiles, multi-chamber construction, galvanized steel reinforcement, HR++ glazing), Aluminium frames on the MB70 70mm profile system, and Steellook heritage frames on the MB-FERROLINE system. Production is fully vertically integrated with own mounting crews and a dedicated service department.

The business serves primarily individual Dutch homeowners (particulieren) undertaking renovation or new-build window replacement, alongside a smaller B2B zakelijk segment and dealers, both serviced centrally from Moergestel. Distribution combines four belevingscentrums (experience showrooms in Moergestel, De Meern, and Purmerend), a discounted outlet, a self-serve e-commerce webshop for standard products (30-day delivery, 5-year warranty), and a custom offertetool offering more than 2,500 made-to-order variants with quotes within one business day and optional in-house installation backed by 10-year warranty and lifetime service. The marketing mix is content/SEO-led via opthoog.nl, with organic social, factory tours, Klantenvertellen review platform engagement (3,200+ reviews, 9.3 average, 11 consecutive years best-rated), and a free ISDE subsidy application service in partnership with Simpel Subsidie.

Commercially, revenue is generated through one-time product sales plus installation and accessory services. Pricing is publicly disclosed for webshop products (Kunststof from ~€126, Aluminium from ~€269, Steellook from ~€359) while custom orders are quote-based. Multiple sector certifications (VKG Keurmerk with Waarborgfonds, SKG-IKOB, KOMO attestation, CE-marking, Politie Keurmerk Veilig Wonen) underpin the regulatory moat. Ownership transferred in 2021 from founder Jan to his sons Noël and Rogier; Jan remains in an advisory capacity. The company is privately held under the legal name Timmerfabriek en Doe-Het-Zelf Centrum A. op 't Hoog B.V. and has not raised external capital.

Expansion highlights5 records

Direct peers

• Weekamp: Dutch family-owned manufacturer of Kunststof (PVC) windows and doors headquartered in Aalten. Closest direct peer — same country, same core product (PVC kozijnen), similar multi-channel showroom and dealer model, and overlapping end customer (Dutch homeowners doing renovation).
• Belisol: Belgian/Dutch window and door specialist with showrooms across Belgium and the Netherlands selling PVC, aluminium, and wooden frames. Direct go-to-market and product-line overlap with Ramenfabriek, including showroom-based D2C selling into the same Dutch homeowner segment.

Broad incumbents

• Veka: German PVC profile extruder and one of the largest upstream suppliers of Kunststof window profiles in Europe. Comparable as a profile system source and indirect competitor through fabricator networks in the Dutch market that use Veka profiles.
• Schüco: German global player in aluminium and PVC-u window, door, and façade systems with established Dutch distribution. Comparable on the MB70 aluminium system supply chain and competes for the same Dutch renovation and commercial projects, though at a much larger scale.
• Profine (Kömmerling): German PVC profile manufacturer behind the Kömmerling brand, a major supplier to Dutch and Benelux window fabricators. Comparable on the upstream profile supply side and competes indirectly through Kömmerling-branded fabricator networks.
• REHAU: German polymer solutions group with a major window and façade systems division. Comparable as an upstream PVC and composite system supplier active in the Dutch market, competing for the same institutional and renovation projects at scale.
• Reynaers Aluminium: Belgian-headquartered premium aluminium window, door, and sliding system supplier with strong Benelux presence. Highly comparable on the aluminium and sliding-door product side and serves the same architect/renovation/developer segments as Ramenfabriek's aluminium line.
• Aluplast: German PVC window system manufacturer selling profiles and systems across Europe. Comparable as a profile supplier whose systems compete in Dutch fabrication, and serves the same PVC kozijnen end-customer through partner fabricators.

Others

• Roto Frank: German hardware specialist supplying hinges, locks, and opening systems to window and door manufacturers — Ramenfabriek already lists Roto roof windows as part of its product range. Comparable as an upstream technology partner rather than a direct competitor, but central to the hardware stack (incl. PKVW-rated security hardware).

Emerging players

• Hörmann: German family-owned door and frame manufacturer with growing European footprint. Comparable on residential front-door and frame installation, though its core strength is garage and industrial doors; relevant as an adjacent specialist competing for some Dutch renovation and new-build specifications.
