Our Rationel AuraPlus and FormaPlus range of products are aluminium clad timber windows and doors with the highest performance levels. 

The timber is glue-laminated and fully factory treated, meaning they have class leading dimensional stability and won't rot.

The external aluminium cladding protects the internal timber from the worst of the weather, resulting in extremely low maintenance.

Timber is sourced from sustainably managed forests holding FSC certification, so you can be sure that for each tree cut down at least one is planted, continuing the natural carbon store of the forest.

In fact, through Chain of Custody certification it is possible to pinpoint the exact harvest your window or door came from.

Fully factory finished in a huge range of RAL colours, there is no need to paint on site after installation. 

External and internal surfaces can be finished in different colours for no additional charge.

Delivered factory glazed and with all ironmongery installed and ready to use, installation is simple and pain-free.
