Description
The new 4600 Plus Lift and Slide system allows large openings to be covered while ensuring exceptional thermal insulation. Its 80 mm sash depth and special polyamides enable it to achieve a thermal transmittance Uw from 0.65 W/m²K, making it one of the best-performing sliding systems on the market. In addition, the visible perimeter section is reduced to just 120 mm, with a central mullion of only 50 mm, enlarging the glazed area and enhancing the entry of natural light into interior spaces.
