Applications of Low-E Insulation


Green building is not just a trend, but the wave of the future as more and more homeowners and builders demand energy efficient homes and products. ESP Low-E® Insulation products are designed for maximum energy and cost efficiency. Whether it’s under slab, under roof, around duct work or wrapping the entire house, ESP Low-E® Reflective Insulation saves more money on heating and cooling than regular insulation.

Reflective insulation products depend on several things to obtain their R-value: the E value of the aluminium surface, the R value of the core material and the size of the airspaces facing the aluminum.  A 25mm airspace facing the aluminium is ideal because convection cannot move air in this small air space.  Keeping this in mind, you can see the importance of making certain that an airspace is maintained facing the aluminium on both sides if at all possible. The airspace also works as an insulating thermal break. It would be a serious mistake to ignore U value requirements, just as it would be to insulate solely against radiant energy when high R-values are required.  That is why you will find many applications in these guidelines that use combination systems, which include Low-E and a secondary insulation.
