ALT SL160 Lift-and-Slide Patio

ALT SL160 is a lift-and-slide door system with thermal break produced to create the most comfortable panoramic designs. ALT SL160 doors do not occupy the inner space, release large opening and allow to combine several rooms or a room with a terrace.

ALT SL160 lift-and-slide door system with thermal break provides great opportunities — it can replace wall, has high anti-burglary features, improves illumination and significantly saves useful area.

ALT SL160 system is available in various options (one-, two-, three-track systems, different types of thermal efficiency, a wide range of hardware from leading brands), which allows to offer solutions for projects depending on the requirements for thermal efficiency and comfort.

Maximum illumination — additional room space. The height of the leafs can be up to 3,385 mm, max. width — 3,235 mm, door system width with connection elements is increased up to 19,500 mm.

High thermal properties. Due to the use of large polyamide thermal breaks and the possibility of double glazed units installation up to 54 mm thick, the thermal properties of this option are significantly increased.

Safety. The system is equipped with burglar resistant elements and there is an opportunity to use burglar-resistant hardware. ALT SL160 system is certified on compliance with PAS24 class in the UK.

Modern design and comfort in operation. Different types of opening and control (manual, automatic). COMFORT CLOSE mechanism (soft-closing of the leaf). are available in the system. Low threshold (only 45 mm in height).

Fabrication benefits
  • The use of 32 mm wide Anti Bi-Metal polyamide thermal breaks in leaf profiles eliminates the possibility of jamming, corners opening, blowing and frost penetration.
  • Integration with ALT W62 and ALT W72 window and door systems and ALT F50 curtain wall system. Adaptor profiles allow to create easy-to-install and aesthetical joints of ALT SL160 system with ALT W72, ALT W62 or ALT F50 curtain wall system so that unique style and consistency of the exterior and interior appearance are ensured.
  • Reliability. Premium quality of aluminium profiles and accessories. Hardware from leading brands — ensures durable and comfortable system operation.
  • Double-circuit moisture removal ensures excellent tightness of the system and eliminates the need for additional drainage (natural precipitation).
  • Ledge kits with pre-assembled parts save time and simplify the assembly of SL160 systems.
  • Different opening types in the system provide wide opportunities for design and application on various objects.
