Insulating films
Most of a building's heat is lost through its glazing, increasing winter heating costs.
Glass can now incorporate a low emissivity (low-e) coating that reflects radiated heat back into a 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 prohibitive.
The cost-effective and least disruptive answer is an application of Llumar® low emissivity window film, which can reduce heat loss through existing glass by up to 30%.
A typical u-value for a standard double-glazed unit fitted with Llumar® low-e film is 2.8. Typical u-values for a standard double glazed unit with inert gas in the cavity and Llumar® low emissivity film fitted is 2.2 (both are average figures). In addition Llumar® low emissivity films will:
- Reject up to 69% of unwanted solar energy
- Reduce solar glare by up to 64%
- Block 99.5% of harmful UV radiation
