Solid aluminium layer 15 mm. thick fully covering the external part and completely protecting the ELITE wooden window. The aluminium coating can be easily removed in order to be restored or replaced allowing greater flexibility and further possibilities.
Both wooden and aluminium parts of the window can be designed independently and have modern design with simplified lines matching the style of modern houses or a classic design in renovation projects and historic buildings.
The ELITE DUALL delivers exceptional thermal performances due to an additional layer of XPS (polystyrene) 3 cm thick with high thermal insulation capabilities inserted between the wooden window and the aluminium layer. This polystyrene layer with special additives reaches a Lambda value λ of thermal insulation equal to 0.059 W/m2K (0.034 W/m2K window frame), further improving the performance of the wooden window.
