The IDEAL 4000 system combines original design with the efficiency of solutions developed for PVC window manufacturers.
A key example is the sash version that allows the use of double glazing up to 48 mm thick.
Thus, within its most popular PVC profile series, Aluplast provides manufacturers with an even more energy-efficient solution.
Using thicker double glazing with improved thermal insulation — up to 48 mm — in windows with an offset sash ensures excellent energy efficiency performance.
For instance, a reference window measuring 1230 × 1480 mm, equipped with double glazing with a Ug coefficient of 0.5 W/m²K and a thermal spacer, achieves a thermal transmittance coefficient Uw = 0.85 W/m²K
