Rationel

We bring daylight and fresh air into people’s lives

Rationel first manufactured windows and doors in Sdr. Felding in 1954, and ever since the products have characterised quality and excellent workmanship. Based on this solid foundation, Rationel has developed into an international company with sales activities in Denmark, Great Britain and Ireland.

As the market has developed, regulations and expectations changed, Rationel has continuously sought to improve and expand its product range including efficient and energy saving products that exceed the statutory requirements of the future, whilst not compromising security, comfort or functionality.

Rationel is part of the DOVISTA Group which consists of a number of leading door and window companies in Europe.

NOTE!

If you purchased your windows and doors through a distributor, please report any issues directly back to the distributor as they will need to make the claim to Rationel. Your distributor will ensure you are updated during the process of the claim.

If you are unsure of who your distributor is or moved into a property with Rationel windows and doors already installed, please continue to submit the claim yourself.
