Thermally Enhanced Windows

Our European standard, high performance window systems have been designed to meet the requirements of LEED and BREEAM. They come with a variety of opening possibilities and thermal performances as low as 0.084 Btu (th)/hour/foot²/°F. This significantly reduces energy use and operating costs.

Manufactured with durable aluminum profiles,  our high performance window systems are evaluated and tested to AAMA 101 for windows and doors meeting the CW PG50 grade. They are available anodized, or with a single or dual color polyester powder coating finish, to meet ASTM 2604.

Strength and durability of our Aluminum windows

To add to the already strong aluminum design, we fabricate all of our ST windows with cast aluminum corner and transom cleats.

Our window systems also come with heavy-duty friction hinges and multipoint locking systems for added security. The versatility of the locking system allows a design team to incorporate extra-large sashes.
