With the innovative SLIMLINE® 3S lift-and-slide door, BECKER 360 offers the world's first lift-and-slide door with an outer frame width of just 50 mm. This halves the usual frame width and the slender sliding door SLIMLINE® 3S made of wood-aluminum or wood-metal is almost frameless. The sleek design of the frame allows large glass surfaces for high light and opens up new architectural solutions for the sophisticated window and facade design. Due to the narrow 50 mm frame, the incidence of light and the thermal insulation are optimized by about 15 percent. With regard to energy-efficient construction and living, the highly heat-insulating SLIMLINE® 3S lift-and-slide door system achieves excellent thermal protection values. Even a passive house suitability is given. In addition, the slim SLIMLINE® 3S lift-and-slide door is also suitable for designing very large window facades and mullion-and-transom façades due to its sturdy construction.
