Timber windows and doors

Rationel timber windows and doors have a long service life aswell as being sustainable and easy to clean and maintain.

The ‘energy-contributing’ Rationel FORMA windows offer the same excellent properties
as Rationel FORMAPLUS, but these windows are made entirely from timber. The angled glazing bead and ovolo moulded profile make it an ideal choice for country-style and traditional designs.

Rationel FORMA ensures that high levels of daylight and solar heat gain are achieved. This free heat is the best energy source available and also provides a healthy and comfortable indoor climate. These windows come with security ironmongery as standard, and are suitable for Passiv Haus buildings.

The Aura range offers double & triple glazed windows made entirely of timber, therefore you can combine the natural look with a future-orientated, clean design for modern buildings.

Rationel Aura ensures high levels of daylight and solar heat gain, the best insulation available, and thus free heat and create a healthy indoor climate.
