Lumis

Lumis is a modern, triple glazed flush casement composite window. The constructional core is made- up of layered, glued scantling free from any knots. External protection of the window is aluminum cladding powder coated according to the RAL colour chart. Due to the combination of timber and aluminum Lumis is marked with excellent aesthetic and usable features. Triple glazed, 48mm thick (Ug=0,5 W/m²K) glazing package and skilfully designed construction with three gaskets between frame and sash allow achieving thermal parameter Uw = 0,76 W/m²K for a reference window.
Lumis is also characterized by high airtightness and enhanced burglary resistance. The innovative construction of the profiles with the application of adjustable Siegenia and PN fittings in the Lumis window and door system results in achieving requirements of anti-burglary demands according to PAS24 norm.
