Polar Window

What Polar Window does

Polarfönster (Nya Polarfönster AB) is a Swedish window and door manufacturer founded in 1990 and headquartered in Korpilombolo, Norrbotten, in northern Sweden. The company designs and produces made-to-order windows and doors — including fixed, pivot, side-hinged, top-hinged, and bottom-hinged windows, plus window doors, French/patio doors, and accessories — from slow-grown Norrlandic pine (kärnfura) that takes 120-150 years to mature, with optional aluminium-clad exterior construction for reduced maintenance. Its products are engineered for Nordic cold-climate performance, with triple-glazed configurations achieving U-values as low as 0.67, and a 10-year warranty against condensation and frame/sash rot.

The company operates a hybrid go-to-market combining a direct-to-consumer e-commerce web shop with an interactive online window designer for self-service configuration, regional sales managers covering Sweden's central (Mitt) and southern (Syd) regions, a B2B dealer portal serving construction companies, architects, house manufacturers, and retailers, and in-house installation services in Norrbotten and Västerbotten. Revenue derives primarily from one-time sales of custom windows and doors (premium pricing around 9,000-10,000 SEK per fully-configured window), professional installation services in northern Sweden, and accessories such as mosquito nets and security hardware. Its flagship enterprise relationship is a 20+ year supply partnership with house manufacturer Älvsbyhus. The company has no disclosed external investors, no funding rounds, and no M&A activity; it operates solely within Sweden.
