Kastrup Vinduet

What Kastrup Vinduet does

Kastrup Vinduet, operating legally as Kastrup A/S (CVR 25473434), is a Danish manufacturer of windows and doors founded in 1995 and headquartered in Holstebro. The company produces a full materials portfolio spanning wood/aluminum composites, solid wood, and PVC, distinguishing it as the only Danish manufacturer offering this complete range. Production is concentrated across two factories in West Jutland — Holstebro for plastic and wood lines and Skive for CNC-machined wood/aluminum assemblies — supported by three customer-facing showrooms in Holstebro, Aarhus, and the Copenhagen area (Glostrup).

The product catalog comprises windows in series such as Basic, INVI, Natur, Miljø, Kultur, and Standard+, plus facade/front doors, sliding doors, and terrace doors, along with a maintenance-oriented spare-parts line. Technical positioning centers on long durability, modern design, energy efficiency compliant with the Danish BR2020 building standard, and customization to project-specific specifications (with pricing quoted per project rather than via public list prices). The company holds an Environmental Product Declaration (MD-24196-DK, valid 21-01-2025 to 21-01-2030) and is a member of the Danske VinduesIndustrien trade association, observing common Danish industry sales and delivery conditions.

The business model is B2B2C. Kastrup does not sell direct to private end customers; instead, all products flow through a nationwide network of certified craftsmen (håndværksmestre), carpenters, and window dealers who handle quoting, installation, and after-sales service. Kastrup provides direct sales support to professional buyers (architects and contractors) and operates showrooms where prospective buyers can experience products pre-purchase, with the Copenhagen location staffed by appointment. Customer segments split into private homeowners and professional craftsmen as co-primary, with named reference projects spanning architects (Lundhild Arkitekter), builders (Vem Byg), and community/non-profit projects (Harrevig Forsamlingshus). Revenue is generated through one-time project-based sales of customized window and door assemblies, with no subscription or recurring revenue model disclosed.

Expansion highlights4 records

Regional players

• Aluplast: German manufacturer of uPVC window and door profile systems supplying fabricators across Europe. Indirect competitor to Kastrup's plastic window line through fabricator partners in Denmark and other Nordic markets.
• Outline (Outline Vinduer): Danish window manufacturer focused on wood/alu and uPVC products for the domestic market. Comparable regional competitor to Kastrup in Denmark, with overlapping target customers and craftsman channel distribution.

Direct peers

• Idealcombi: Danish manufacturer of windows and exterior doors in wood, wood/alu, and alu-clad systems. Direct competitor to Kastrup in the Danish residential and light commercial market, with overlapping product lines and a similar professional-channel go-to-market.
• Rationel Vinduer (Dovista): Danish-designed window and door brand owned by the Dovista group, offering wood/alu and timber products to Danish homeowners and builders. Competes with Kastrup in mid- to premium residential segments and shares the craftsman-led distribution model.
• Velfac: Danish window and door manufacturer serving both private and professional customers through a craftsman/dealer network. Direct competitor to Kastrup across wood/alu and similar material ranges, with comparable Danish-made positioning and showroom model.

Broad incumbents

• VELUX Group: Large Danish-headquartered manufacturer of roof windows and skylights with broader fenestration exposure. Larger and more international than Kastrup, with overlapping end-customer demand for daylighting and energy-efficient openings, but focused on roof rather than vertical windows.
• Schüco: German global manufacturer of window, door, and façade systems in aluminum, uPVC, and steel. Competes with Kastrup in the premium and commercial specification channel across Europe, though not specialized in the Danish residential segment.
• Inwido: Swedish-listed group owning multiple European window and door brands, including Dovista. A scale consolidator in Nordic and northern European fenestration, with comparable product categories and indirect competition for premium Danish residential projects.
• Reynaers Aluminium: Belgian manufacturer of aluminum window, door, and curtain-wall systems for residential and commercial projects. Comparable to Kastrup's wood/alu range and targets the same premium architectural specification channel, but with a broader European footprint.
• Internorm: Austrian manufacturer of wood/alu, uPVC, and timber-aluminum windows and doors, active across Europe. Competes with Kastrup's premium wood/alu and timber ranges and supplies the energy-efficient segment targeted at Danish BR2020-class projects.
