Where This Heavy-Duty Sliding Window Adds Value

The upgrade is visible in the thicker profile, stronger roller capacity, larger height range, and higher water and wind pressure references.

Heavy 2.0mm Aluminum Profile

A thicker aluminum structure provides a more substantial frame for larger residential and project openings.

Stronger Roller Options

A single roller supports up to 55kg, while the dual-roller configuration supports up to 140kg per sash.

Larger Height Capability

Sliding sashes can be produced from 350–1200mm wide and 300–2050mm high for more flexible opening proportions.

Higher Water Resistance

The latest specification lists 450Pa water resistance, making this system the stronger two-track option in the range.

Up to 4000Pa Wind Pressure

The reinforced structure supports a wind pressure reference up to 4000Pa when properly sized and installed.

More Layout Flexibility
