ST4-600 Lift & Slide Door

Our new lift & slide door system that exhibits the best thermal insulation in all the sliding range with transmissions as low as 0.9 Wm2/K.
This maximum energy efficiency is possible thanks to the perfect combination of polyamide thermal breaks and cross-linked polyethylene foam combined with the use of high-performance triple glazed units (possible thickness up to 55 mm) and large size sliders. Acoustically this combination of framing and high-performance acoustic glass will deliver a noticeable noise reduction with exceptional thermal insulation.

The possibility of large sash dimensions makes the ST4-600 system the ideal choice for enclosing large spaces while maintaining a high level of luminosity. The system offers a modern style with straight style both in sashes and fixed panels.
