Rationel windows – in detail

Impressive durability

With an expected lifetime of 60 years, all-timber AURA and FORMA windows offer impressive durability. For added peace of mind, and for more demanding locations, choose AURAPLUS or FORMAPLUS. Both feature an alu-clad external frame which adds 20+ years to your windows, and only needs minimal maintenance.

Cosy and quiet

Stay warm and cosy with Rationel. Choose from double or triple glazing to help achieve the ideal comfort level in every room. Excellent insulation also means great noise reduction, so add peace and quiet to the list of Rationel benefits.

Protect the environment

Reduce your carbon footprint, and your energy bills, with energy efficient windows. Beautiful slim frames (made from FSC®-certified wood) are designed to increase daylight and Rationel windows also carry the Danish ‘Indoor Climate Label’, proof that they won’t release toxic substances after they’re installed.

Safe as houses

Windows tailored to your home

Rationel windows are manufactured to order so make every window your own. Choose from a range of different opening types, and from an impressive palette of colours and finishes – you can even select a different colour inside and out. And don’t forget the glass – if you need more privacy or security, greater solar control, better noise protection, or even brightly coloured panels, we have the options to choose from.
