The structural integrity of fiberglass framing in conjunction with our advanced fused corner joint technology makes the SeriousWindows Heavy Commercial series indestructible and impervious to air and water, preserving the energy efficiency performance of the window for a lifetime.

The SeriousWindows Heavy Commercial series are carefully engineered, offering unbeatable longitudinal and transverse strength, while maintaining the similar sight lines as aluminum windows, and a significantly lower U-Value for best in class energy efficiency. With proprietary, indestructible, fused joints creating solid corners, the SeriousWindows Heavy Commercial series features industry leading air and water infiltration rates.

Serious Materials Partnership with AAMA

The American Architectural Manufacturers Association (AAMA) sets stringent performance standards for all fenestration products, and provides third-party validation of product performance and quality. Serious Materials has partnered with AAMA to provide some of the highest performing windows on the market the meet the toughest fenestration specifications in the industry.

Tested to AAMA/WDMA/ CSA 101/I.S.2./A440-08, the SeriousWindows Heavy Commercial series achieves Heavy Commercial (CW) ratings across the line, as well as monumental or oversized ratings along with large mulled configuration in the heavy commercial category.

AAMA certified SeriousWindow Heavy Commercial Series window ensures:

• AAMA ratings (gateway sizes) CW100
• A window that is AAMA gold labeled has passed required performance tests for resistance to air leakage, water penetration and wind pressure.
• Performance tests that were conducted at an independent AAMA-accredited lab with an Industry-leading air infiltration of <0.01 and water penetration of 15 psf
• Durable, tough coatings warranted to meet AAMA 623-07
• The production line units are built to the same specifications as the window that was tested.
• Manufacturing plant production lines, component inventory, and quality control records are checked annually through two surprise inspections by an independent third-party.
