Rationel AURAPLUS / Rationel FORMAPLUS

The Rationel top-guided outward opening triple-glazed windows with aluminium cladding can be made as Rationel AURAPLUS or Rationel FORMAPLUS.

The Rationel AURAPLUS wood/aluminium windows are constructed using the same solid timber structure as our all-timber windows, with the addition of external aluminium cladding. Rationel AURAPLUS personifies clean lines. The sleek, flat frame gives your window a flush finish for a truly modern, Scandinavian feel. Windows are made to measure and come in a large range of opening functions. 

Glazing can be triple-glazed or double-glazed as per requirement. Optional glazing bars can increase the architectural elegance of this style. The external cladding comes in hundreds of colours and gives you the flexibility to have one colour inside your home and another on the outside.

Made from sustainably sourced timber, your windows and doors will last for decades if looked after. 

And with the external aluminium cladding, maintenance becomes minimal and life expectancy rises.

The Rationel FORMAPLUS wood/aluminium windows are constructed using the same solid timber structure as our all-timber windows, with the addition of external aluminium cladding. 

Rationel FORMAPLUS is designed to complement traditional architecture and the FORMAPLUS window range comes with angled glazing bead and ovolo moulded profile making it an ideal choice for country-style and traditional designs. Windows are made to measure and come in a large range of opening functions. 

Rationel FORMAPLUS is available with or without glazing bars which particularly suits this style of windows. Glazing can be triple-glazed or double-glazed as per requirement and an extensive range of colour choices are available.
