Altek is announcing a major advancement with the achievement of AW classification for four products in its ADG collection: the casement window, hopper window, fixed window, and terrace door, according to the North American NAFS standard. This distinction, one of the most demanding in the industry, confirms the strength and performance of systems designed for institutional, commercial, and multi-residential projects.

The AW rating ensures superior performance under demanding conditions, backed by rigorous testing for load resistance, water tightness, and operating cycle durability. With performance reaching AW-CP100 and sash weights of up to 130 kg, these products demonstrate exceptional mechanical strength. Eurogroove assemblies also allow for the design of large-format openings, meeting the needs of today’s architectural projects.

On the thermal front, the all-aluminum structure combined with a PVC core achieves a U-value as low as 1.52 (0.27 imperial), outperforming systems using a single polyamide thermal break. Available in double or triple glazing, these products ensure optimal energy efficiency. Built to last, they also help reduce replacement costs in rental and institutional buildings.

Backed by more than 40 years of expertise developed within ADG, Altek now offers a complete solution that combines reliability, performance, durability, and compliance. The ADG collection now stands as a top choice for projects where quality, precision, and long-term value are essential.
