ETERNITY

Aluminium and wood double glazed window

Manufacturer Alpilegno

Wooden-aluminium window produced with natural and completely recyclable materials. This product blends the warmth of wooden frames on the inside with optimal protection
against atmospheric elements on the outside, thanks to the external aluminium profile. Thermal and acoustic insulation is guaranteed by the glazing using panes of different
thicknesses, to improve acoustic insulation, and the use of FOUR seals. The internal wooden profile features a modern design and can be personalised with wood types or finishes
as required, while the external aluminium profile can have a more traditional style with rounded edges or more contemporary with squared off edges.
