ASSEMBLY with glues to norm UNI EN 204-04.

MAIN FRAME new conception with internal wood profile thickness 72mm, covered outside with an aluminium profile of thickness mm 15, mechanically fastened with clips. The wood and aluminium profiles are joined by a rubber gasket forming a closed chamber that considerably improves the transmittance coefficient Uf of the window.

OPENING SASHES internal profile in wood of thickness 72 mm and outer facing profile in aluminium thickness 15 mm, mechanically fastened with clips, with covering rubber gasket. A peculiarity of this window is that the glazing is positioned within a seat entirely of wood, thus avoiding any contact between glass and aluminium.

INSULATION water and air sealing, with 3 EPDM heat/noise gaskets welded at the corners and inserted in the main frame for better wind and water resistance, easier cleaning and a better window appearance.

HARDWARE New generation hardware with 13 mm offset, hardware axis shifted towards the middle of the profile to increase the stability of the strike plate fastenings. This system ensures the window has greater resistance to pulling-out and burglary and that maintenance is simple and reduced.
