What Ekstrands does

Ekstrands Dörrar & Fönster AB is a Swedish premium manufacturer of custom-made exterior doors, interior doors, windows, and sliding door systems for residential, BRF (housing cooperative), commercial, and heritage-renovation applications. Founded in 1945 (some sources cite 1950) and headquartered in Osby, Sweden, the company is wholly owned by the family holding Ekstrand & Son AB and operates as a fully made-to-order manufacturer with no inventory, producing products to millimeter precision at heights up to 3.1 meters. The product portfolio is differentiated by market-leading thermal insulation (U-values as low as 0.69W for exterior doors and 0.77W/m²K for the Energy Concept 90 window), proprietary construction features including concealed I-frame mounting, Dreh-Kip inward-opening windows with triple sealing strips, and certifications spanning PHI passive house, RC3 security, and CE-marked performance across the range.

Underlying technology combines high-performance wood and wood/aluminum window systems (EC/90, E68, E78, E92, Patio Nova, Patio Panorama) with a deep door range (exterior, interior, pivot, fire/acoustic-rated, RC3, and limited editions). Co-designed lines include the BAS Family (with Krook & Tjäder), Block 600 (with White Arkitekter), and limited editions Willow 110K and Clue 100K (with Wonderwall Studios), supported by FSB antibacterial handles, BIM objects on BIMobject, and a six-week extended climate test for doors. Manufacturing lead times are typically three to seven working weeks.

The business model combines one-time product sales (custom-made-to-order) with professional installation services using the company's own carpenters (the All Inclusive package), distributed through five permanent showrooms (Osby, Stockholm, Gothenburg, Arlöv, Linköping), traveling field sales representatives, a 1,000 m² outlet in Osby, and dedicated architect and project teams. Customer financing is provided through partnerships with WasaKredit and LF Finans. Primary customer segments are individual homeowners of premium single-family residences, architects and developers, BRF housing cooperatives, and select commercial and heritage renovation projects (e.g., Grand Hotel Saltsjöbaden, Rådhuset Kristianstad). The Ekstrand & Son AB group reports turnover exceeding 200 MSEK and has held the AAA (highest creditworthiness) Bisnode rating with Diamond diploma for over 25 years.
