Rationel use only the highest quality raw materials and the very best workmanship. Most noteworthy, the timber used originates from North European FSC certified forests – meaning that they do not cut down more trees than the forest is able to reproduce.
Rationel Windows aim to create comfortable, cost-effective and energy-efficient homes. So we guarantee that you’ll receive one of the market’s highest quality efficient products.
A full range of Scandinavian windows are on offer, including side-hung, top-guided and tilt and turn windows. Entrance doors, terraced doors and full panelled doors are also configurable.
