- The I-Strut is mechanically bonded between the aluminum frame.
- The I-Strut and the aluminum frame have identical coefficients of expansion. As a result, thermal break I-Strut systems resist the thermal cycling, which occurs in actual building conditions better than any method available. The standards used to measure I-Strut are published in AAMA TIR-A8-04.
- The strut resists corrosive effects of chemicals used in cleaning in both maintenance, manufacturing, and installation.
- High melting temperature - I-Strut will withstand heat in fenestration systems better than any other system, resulting in improved structural integrity.
- The use of polyamide strut also allows for a new versatile level of product design. With this method the two separate extrusions can easily have different paint or anodize combinations, which adds significant flexibility to each individual use.
- Dry shrinkage concern with polyurethane is eliminated.
- Increased structural strength.
- Ability to make various window systems with the same aluminum profiles, using different sized polyamide struts.
