With the introduction of the new pressure treated lumber products many contractors have found that a barrier is needed to keep their metal safe from chemical induced corrosion. The new wood products containing copper azole (“CA”) or alkaline copper quaternary (“ACQ”) have higher levels of copper than previous pressure treated lumbers. These products when in contact with metal panels or aluminum faced insulation, such as Low-E™ Insulation, can cause electrolysis or rusting. Alum-E-Shield eliminates these concerns.
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 and housewrap.
