4900 SLIDING HI // Sliding window with benefits of a hinged one


CORTIZO lauches new 4900 Sliding HI system, a new standard sliding window with excellent thermic and acoustic benefits, characterized by a straight and avant-garde aesthetic with a slim interlock of just 35 mm of sight line, which allows to maximize the window's glazed surface in order to allow light input.

The new CORTIZO sliding window was born as an evolution of the 4200, one of the most demanded by its customers in recent years, and which stands out for its great thermal (Uw from 1.2 W/m²K) and acoustic (Rw up to 40 dB ) insulation, features that are favored by its large glazing capacity of up to 36 mm, which allows for triple glazing, as well as a thermal break zone with 34 mm polyamide strips. All these characteristics are reinforced by the great results obtained in the AEV test benches: Class 4 (air permeability); Class 7A (watertightness) and Class C5 (wind resistance). The 4900 Sliding HI system allows a combination of up to 6 sashes, each with maximum dimensions of 2200 mm wide and 2600 mm high, and a weight of 240 kg.
