Exclusively conceived and produced the most contemporary evolution
External view of a sliding door with Vitrum Double system

With over one hundred years of tradition in creating high quality windows and doors, Carminati Serramenti has exclusively conceived and produced the most contemporary evolution of these articles, incorporating innovation and design. Vitrum Double is our new interpretation of invisible windows and doors, obtained protecting the panes internally and externally with screen painted glass with the result of an innovative and of high aesthetic impact product.
Design and elegance are perfectly combined with efficiency. Vitrum Double windows provide excellent thermal and acoustic performances and are ideal for new and refurbished houses. They require no maintenance as the wood frame has only structural and thermal insulation functions. The frame is externally protected by aluminium cladding, while on the panes the system “internal glass – structural wood – external glass” allows the wood frame to be protected against all atmospheric agents and guarantees an unmatched durability. Corners are welded and varnished for lacquered finishes and bronze only. Glass can come with screen-painting in all RAL colours.

data sheet

thermal characteristics

Uf calculation based on a single sash window 1100×1450.

Thermal transmittance of the frame:
Uf = 1.33 W/m2K for light wood (i.e. fir) – UNI EN 10077-2

TThermal transmittance of the frame:
Uf = 1.63 W/m2K for heavy wood (i.e. oak) – UNI EN 10077-2

*The UW thermal transmittance of the window must be calculated each time based on the size, the type and the glass used.
