frames are strong and durable, but they readily conduct heat. To avoid heat loss and condensation, aluminum frames are required to have a thermal barrier inside made from rigid foam, polyurethane or wood, to reduce heat transfer. While aluminum frames are durable and require little maintenance, they have poor insulating properties. Some Aluminum frames typically have mitred joints in the corners, which can allow water to leak into the wall if the joints are not properly sealed or the seals fail.
