The amount of heat entering a room through windows and skylights in summer can be as high as 87% of the rooms total heat! On a hot day, every square metre of your windows can let in as much heat as a 1000W heater! Cosy 24/7 allows the beautiful natural light you love to enter a room, while keeping up to 42% of unwanted solar heat outside. Without any air conditioning, this can keep rooms cooler by up to 7 degrees!
Untreated double glazing lets UV and IR into your home which means your home inevitably overheats. Standard window tints focus on UV only making it far less effective at preventing heat gain. The worst part is most tints also cut out a large percentage of visible light causing a room to feel dark and gloomy.
