An installation of EnviroFilm adds a thermal barrier to the inside of the glass pane, preventing heat from escaping. This can be acheived with a completely clear film or with our various tinted privacy films.
Enviro Clarity Low-e is completely clear from both sides and will reduce the U Value down to just 1.08 - this is even lower than Argon Filled Triple Glazing. As it is clear & non reflective it is fully authorised for use on listed properties.
Don't throw your hard earned money out of the window! A huge amount of heat is lost through your windows in wintertime. A recent client who had an EnviroFilm installation reported a £1 per day saving on his smart meter.
