SolarCool External Heat Rejection Window Film is engineered to reflect solar heat and glare before it passes through the glass, making it one of the most effective solutions for reducing heat gain and improving occupant comfort. It is particularly well suited to laminated glazing and modern glass systems with specialist coatings, where the installation of traditional internal window films may not be recommended due to the glass’s unique thermal properties.
External SolarCool window film is highly effective at reducing solar heat gain while still allowing natural light to pass through the glazing. It delivers excellent glare reduction of up to 40%, helping to create a more comfortable indoor environment without significantly impacting daylight levels.
Technical Spec: 55% visible light transmission, 48% solar energy reduction, IR Rejection 65%
External Heat Rejection Window Film SolarCool โ is highly effective at reducing solar heat gain, whilst at the same time continuing to allow some natural light transmission.ย External window films are designed to reflect solar heat and glare before it passes through the glass, making them one of the most effective solutions for reducing heat gain and improving occupant comfort. They are particularly well suited to laminated glazing and modern glass systems featuring specialist coatings, where the installation of traditional internal window films may not be recommended due to the glass’s unique thermal properties.
When internal window film is applied to insulated laminated glass units or triple-glazed systems, it can increase the temperature of the inner pane relative to the outer pane. This temperature imbalance may place additional stress on the glass, potentially leading to cracking or breakage.
By applying the film to the exterior pane instead, the heat absorption occurs on the outer surface of the glazing unit. The external pane is able to dissipate a greater proportion of the absorbed solar energy back into the atmosphere, reducing thermal stress within the glass assembly. As a result, the risk of glass damage is significantly minimised while still delivering excellent solar heat and glare reduction.
