Internally made of screen painted glass

View of the living area with Invitrum lift and slide

Simple lines and surfaces made completely of glass give light, transparency and depth. Glass is the fundamental element of the leaf, without interruption, and gives comfort and beauty to the window enriching it with new light and making the superfluous disappear, leaving only the essential visible.
Invitrum is internally made of screen painted glass which can be done in various colours and covers the frame, and externally in wood or aluminium, resulting ideal for purely modern habitations; it gives the home the touch of elegance and sophistication everyone desires.

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

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

Thermal transmittance of the window to:
UW = 1,1 W/m2K *

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

The entire procedure is performed using ADLER water-based products and the frames also carry a warranty regarding the duration of the varnish (see the illustration brochure).
All the surfaces are completely sanded and finished by hand.

Glass varnishing:
The glass is varnished in various colours using screen printing

gluing

Wood gluing:
High-resistant vinyl-based glues are used on the joints according to DIN 68602 Group B3 Standards.

Wood-glass gluing:
The wood is structurally glued to the glass using Sika glues

assembly

Using tenons with open cross-section and two and a half dowels.
