Windows are often the main source of heat loss and heat gain in a room. Magnetite's panels have been tested and approved by the Windows Energy Rating Scheme (WERS). Magnetite's thermal glazing combined with the MEP tints get a Windows Energy Rating of five stars, which is as effective as argon filled double glazing and matched by none other on price and quality.

Margaret of Newport, NSW, found that the skylights in the family room were getting too hot to touch from the sun, resulting in the room becoming an unbearable temperature. Magnetite Sydney was able to tint the existing windows and install the insulating panels to help reduce the transfer of heat during summer. Margaret was very pleased with the result, commenting that
"the reflective film combined with the Magnetite thermal panels have made a huge difference to the heat coming into our family room." She then added "thanks for the good workmanship and for the professionalism."
