ST4-600 Lift and Slide

Energy-Efficient, High-Performance Sliding Door

Our ST4-600 Lift & Slide exhibits the best thermal insulation in all the sliding range with transmissions as low as 0.9 Wm2/K. This 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 2 3/16“) and large size sliders. Acoustically this combination of framing and high-performance acoustic glass will deliver a noticeable noise reduction with exceptional thermal insulation.
