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.
