Polar Wrap

WeatherAll XL has cut hinges to help ensure it lies absolutely flat on the wall. XL is ideally suited for over sheathing application or for bridging narrow profile siding like Triple 3" or Double 4". XL's lighter density also results in a flexible product that simplifies wrapping corners. Over 1,000 breather holes in every square foot of WeatherAll. These tiny holes don't affect rigidity but do enhance water vapor permeability. Many other manufactures skip this important step and deliver products that can form a vapor barrier. This can result in trapped moisture and lead to mold formation or dry rot.
