Glazing and Aluminum Fabrication Industry Briefing

Modern codes require much lower U-values, meaning standard non-thermal frames are no longer viable for most exterior projects. You must transition to frames with advanced polyamide thermal barriers and space for thick double or triple-glazed units. This shift requires updating your fabrication tooling to handle the composite profile materials without damaging the thermal strip.

The U-value measures how much heat escapes through the window assembly, while the SHGC measures how much solar radiation enters the building. For fabricators, U-value dictates your frame selection and spacer technology, whereas SHGC is primarily managed by choosing the correct low-emissivity glass coatings. Balancing both ensures the completed window assembly passes strict local building energy assessments.

You must use laminated toughened glass of the correct thickness specified for the local occupancy type and fall-height risk. Frame fixings must be engineered and anchored using approved chemical or mechanical fasteners that match the structural base material. Always keep the signed manufacturer’s engineering certs and material mill certificates on file for the final sign-off.

Yes, public and large commercial tenders increasingly mandate Environmental Product Declarations (EPDs) showing the carbon footprint of your metal. Sourcing profiles made from low-carbon or high-recycled-content aluminum is now a baseline requirement to qualify for green building projects. Fabricators must secure supply chain traceability documents from their extruders to submit with their bids.
