N27000

In response to the contemporary architecture trends, it was developed the n27 000 system which allows the execution of windows until 38 mm infillings, where the 26,5 mm view on head, jamb and sill merges into the construction, resulting in high levels of luminosity, not disregarding the functionality.
The integration of the frame in the construction materials highlights the relationship between the inside and the outside, allowing an unlimited view, as well as regarding the total opening of the window in corners.
With remarkable thermal and acoustic performances, this system is positioned as a preferential product for architectural projects in which aesthetic and luminosity considerations are assumed as fundamental premises.
Minimalist sliding system, which keeps the same view of 26,5 mm in the meeting rail allows through the use of structural glass, the execution of windows weighing up to 300 kg per sash.
With a depth of 147,2 mm for the bi-rail outer frame and 46,6 mm for the sash, the n27 000 system is available in mono-rail, bi-rail and tri-rail versions, using structural connection thermal break strips.
