KPK Doors and Windows

What KPK Doors and Windows does

KPK Doors and Windows (legal name: KPK Døre og Vinduer A/S) is a Danish manufacturer of custom-made windows and doors, founded in the 1950s and operating from a single factory in Nykøbing Mors, Denmark. The company employs approximately 250 people and produces timber and timber/aluminum windows and doors — including top-hung, side-hung, tilt-and-turn, cottage/Dannebrogs, reversible, fixed-frame, and the VISION minimalist windows, plus facade, terrace, folding, window, and lift-slide doors — all built to order and carrying CE marking, energy labels, a 10-year warranty, and certified timber sourcing. The business model is exclusively B2B2C: KPK sells only to registered professional craftsmen (tømrere/snedkere), who install the products for end consumers, supported by three physical showrooms (Nykøbing Mors, Vejle, Sjælland), a dealer locator on the website, and a Quick Delivery service offering 6-working-day turnaround for a premium fee.

Revenue mechanics combine custom unit-pricing on made-to-measure projects, a dedicated webshop selling accessories and spare parts (DKK 65–3,455), and the Quick Delivery upsell. The KPK 365 digital platform (web and mobile app) is the primary commercial interface for craftsmen, enabling instant pricing, quote generation, and order tracking — directly integrated with daily workflows of named installers such as Tach's Tømrer-Snedker and Børge Jakobsen & Søn. Marketing is conducted through social media, newsletters, content, and brand sponsorships (DanskHåndbold, DM in Skills), while the webshop delivers manufacturer-supplied spare parts to both trade and private customers. The company is wholly owned by Inwido, the Scandinavian windows and doors conglomerate, which provides strategic direction and group-level resources.

• DOVISTA: DOVISTA is a leading European window and door group owning multiple brands including Rationel Vinduer. As a broader group competitor to Inwido (KPK's parent), it competes at the portfolio level across multiple Nordic and European markets.
• Andersen Windows & Doors: Andersen is a large US-based window and door manufacturer with a broad wood, wood-clad, and composite product portfolio. Comparable to KPK as a competing window/door manufacturer serving residential new-build and renovation markets, though operating at much greater scale and in a different geography.

Regional players

While not a direct window manufacturer, it is comparable to KPK as a Danish building-envelope technology company with overlap in energy-efficiency and smart-window automation themes.
