Technical details

PVC profiles stand out for the number and layout of their different chambers: the higher the number of chambers, the better the heat insulation. Our systems use 5 or 6 chambers with a depth from 74 to 83 mm and with a suitable glazed section, they provide Uw values below 0,84 W/m2K. Glass plays a fundamental role in ensuring a high level of heat and sound insulation. The addition of Argon gas notably improves the heat and sound performance of glass, which means our windows are even better performing and ensure a high level of living comfort. Another basic element in a door or window is its hardware. At Daunia we only use Roto NT products, which act as a barrier against break-ins, can withstand the most extreme climate conditions, and are tested for 30,000 casement opening cycles and 20,000 bottom hung openings, as well as having special "RotoSil Nano” technology surface treatment.
