Windows / Aluminum Windows / Milgard

Aluminum window frames are light, strong, durable, and easily extruded into the complex shapes required for window parts. Aluminum frames are available in anodized and factory-baked enamel finishes that are extremely durable and low-maintenance.

Architects and builders have long appreciated aluminum windows for their overall strength, lasting value, and ability to configure into large combinations to maximize views. Milgard takes aluminum windows a step further by treating them as a design element not just a low-cost alternative. As a result, our unique aluminum windows are found in projects ranging from entry-level homes and multifamily projects to high-end custom homes and light commercial applications.

The biggest disadvantage of aluminum as a window frame material is its high thermal conductance. It readily conducts heat, greatly raising the overall U-factor of a window unit. In cold climates, a simple aluminum frame can easily become cold enough to condense moisture or frost on the inside surfaces of window frames. Even more than the problem of heat loss, the condensation problem spurred has development of better insulating aluminum frames.
