Eco Window FilmA lot of a building's heat is lost through it's glazing, increasing winter heating costs.
Most glass can now incorporate a low emissivity (low-e) coating which reflects radiated heat back into the room, but low-e glass does very little for other glass-related problems such as solar heat gain, solar glare and UV radiation transmission. And if you have existing glazing and want to upgrade, the cost and the disruption can be huge.
The most cost effective and least disruptive answer is an application of UV Shield low emissivity eco-window film, which can reduce the heat loss through the existing glass by up to 24%.
A typical u-value for a standard 4mm single glazed panel with no film is 5.71. With UV Shield Eco-film this is reduced to 4.31 making a winter heat saving of 24%.
A typical u value for a double glazed unit with no film is 2.72 but with UV Shield Eco-film this is reduced to 2.36 making a winter heat saving of 13%.
