Thermal Break Aluminium Profile
Aluminium Alloy Machining Parts
Aluminum window frames are light, strong, durable, and easily extruded into the complex shapes required for window parts. Aluminium
frames are available in anodized and factory-baked enamel finishes that are extremely durable and low-maintenance.
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 has spurred develop-
ment of better insulating aluminum frames.
The most common solution to the heat conduction problem of aluminum frames is to provide "thermal break" by splitting the frame compo-
nent into interior and exterior pieces and use a less conductive material to join them.
