Lift and Slide Doors.

Large glass surfaces, easy operation, secure and fully accessible.

Perfect combination of transparency and heat insulation. Large lifting-sliding doors with small profile widths create rooms flooded with light – if required, with a step-free passageway and an integrated, electric drive for maximum ease of use. But HELT lifting-sliding doors have even more to offer: Feel the ease and silent running with every movement. Their high thermal performance, meeting passive house standard, keeps the rooms cool in summer and warm in winter. And the tested burglary resistance including resistance class RC 2 guarantees a high level of security.

Lifting-sliding Doors from HELT

  • Depending on the opening variant, HELT lifting-sliding doors can be designed with up to six movable sashes. A completely new experience of space is created when they are combined with an all-glass corner or a corner with an opening sash.

  • Lifting-sliding doors from HELT provide for full accessibility of balconies, patios or conservatories. The zero-barrier creates comfortable passageways without any trip hazard.

  • For colour-fast surfaces, HELT lifting-sliding doors are coated with highly weather resistant hwr coatings, available in a unique variety of colours and designs.

HELT S 77 SL opens up new large dimensions and guarantees maximum transparency with its unique innovative frame construction. The new generation of HELT lifting-sliding doors combines a movable monorail casement with fixed frame glazing and minimal view widths. This large frameless glazing with clean lines forms an almost invisible link between the inside and outside, extending the living space beyond its actual limits. The HELT S 77 SL lifting-sliding system is a new architectural design element that creates a new sense of space.

The HELT 77 SL lifting-sliding system creates a harmonized balance between contemporary design, maximum comfort and consistent functionality. Thanks to its elegant and modular construction details, the HELT S 77 SL has unlimited uses in new buildings and renovations.

Additionally, the insulating variant HELT S 77 SL/CC provides for an improved heat insulation due to the optimized design of the central joint, the typical weak point in the insulation of any lifting sliding door. This optimization creates a comfortable climate in the living spaces.
