Thermal Heart technology incorporates a thermal break between the aluminium exterior and interior elements, resulting in windows and doors that are 20% more efficient than standard double glazed products. An additional benefit is the ability to have dual colours - a different colour for interior and exterior.
Note: Thermal Heart products have a thermal break within the system, and in direct sunlight the temperature on the external facing of the product may become very high, relative to inside. There is a potential for the system to experience slight bowing and doors may have difficulty closing smoothly. We stress that this is only a temporary effect and the system will revert back to its normal shape as the aluminium cools. This effect is primarily in dark colours, so it can be minimised by selecting lighter external colours or increasing the shade in the area.
