Robust Yet Elegant Frame

The aluminum frame features a width of 120 mm for the 2-track system and 178 mm for the 3-track system, combined with a 50 mm bottom sill height to strike the perfect balance between structural strength and sleek elegance. The finely finished surface enhances load-bearing capacity and prevents deformation caused by impact or strong winds, adding a luxurious accent to the building’s overall architecture.

Versatile Glass Compatibility

Supporting glass thicknesses up to 31.5 mm, the system accommodates a variety of glass types including safety, acoustic, and insulated options. This flexibility enhances thermal and sound insulation, creating a quiet, comfortable indoor environment while providing optimal safety.

Engineered to withstand high wind pressure up to 2000 Pa (ASTM E330) and achieve water tightness up to 300 Pa (ASTM E331-00), the door protects interior spaces from heavy rain and wind. This preserves a dry, comfortable atmosphere and prevents water damage to the property.
