Sturdy and Refined Frame

Featuring a 120 mm frame depth for 2-track systems and 178 mm for 3-track systems, paired with a 50 mm sill height, the door balances structural strength with sleek elegance. The finely treated frame surface enhances load-bearing capacity and prevents deformation from mechanical impacts or strong winds.

Versatile Glass Compatibility

The door accommodates glass thicknesses up to 31.5 mm, supporting everything from safety glass to acoustic or thermal insulation glass. These flexible glazing options satisfy diverse functional requirements, significantly boosting sound reduction and thermal efficiency to ensure a quiet, comfortable, and safe environment.

Wind Pressure and Water Tightness

Achieving a wind pressure resistance of 2000 Pa (ASTM E330) and a water tightness rating of 300 Pa (ASTM E331-00), the door protects interior spaces against driving rain and harsh winds. These features maintain a dry, cool, and comfortable indoor environment while safeguarding interior finishes over time.
