Grundels Klimatruta
Founded in 1982 in Karlstad, where it remains headquartered today, Grundels has evolved from a small, traditional craftsmanship business into a specialist in window renovation and energy-efficient glazing solutions.
Initially focused on painting and window restoration, the company began developing its expertise in window technology in 1992, introducing its proprietary Grundels Klimatruta solution.
