Cozy on the inside and durable on the outside: HS lift-and-slide doors by UNILUX feature a wooden core for a warm, inviting interior and a robust aluminum exterior for optimal protection, all while offering expansive views of the outdoors. With dimensions reaching up to 10 meters in width and 3 meters in height, they transform your living space into a sunlit veranda. The innovative lift-and-slide mechanism works by lifting the panel via the handle, allowing it to glide effortlessly. The sashes can overlap, creating an opening of up to 4.47 meters within a 7-meter-wide glass surface. HS lift-and-slide doors deliver superior thermal insulation, helping to cut heating costs and reduce CO2 emissions. Typically, they come with triple-pane insulated glass, keeping warmth indoors during winter and heat outdoors during summer. The glazing achieves an outstanding U-value of 0.8 W/(m²K). Additionally, these doors can be customized to be barrier-free, providing smooth transitions between indoor and outdoor spaces.
