Why Window Specifications Matter More Than Most Architects Expect Aluminum windows are specified on virtually every commercial project, yet they are routinely under-specified. A vague call-out like "commercial aluminum windows, thermally broken" leaves a contractor free to install a product that meets the letter of the specification while falling well short of what the building actually demands. Leaks, excessive air infiltration, deflection...

When specifying aluminum fenestration for commercial or residential projects, one decision carries more long-term consequences than almost any other: whether to use thermal break or non-thermal break profiles. Both systems are built on aluminum—strong, durable, and low-maintenance—but they behave very differently when heat is trying to move through your building envelope. This technical comparison breaks down the physics, the performance data, and...

Understanding Wind Load Ratings for Doors and Windows For architects, builders, and facility managers specifying fenestration systems in high-wind regions, wind load ratings are not a marketing concept — they are an engineering obligation. A window or door assembly that fails under wind pressure creates a pressure differential that can lift a roof, flood an interior in seconds, and put occupants at...
