Insulating films

Most heat is lost from a building envelope through its glazing. The installation of double-glazed and sealed units has become common practice, and glass is now manufactured with low-e coatings.

However, low-e glass doesn’t address the problems of solar heat gain, solar glare and UV transmission. Plus the cost of replacing existing glazing can be prohibitive.

The cost-effective answer is an application of Llumar® performance 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® applied 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® performance 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.
