Water Resistant Barrier
LITgistics, Corp. defines weather-resistant barriers as surfaces or walls responsible for preventing air and water infiltration to the building interior. We believe weather-resistive barriers is the single most important layer of the exterior envelope which is why we've dedicated an entire page to emphasize our stands on WRB application. Reliable WRB will keep building materials dry and improve building durability while also decreasing maintenance costs and reducing the risk of problems caused by moisture
When choosing a brand of WRB you should really consider a reliable product. Some products are expensive; however, they are the best kind of insurance you can get. With the right kind of system for you and the proper installation you can rest assured your home is safe.
Types of weather-resistant barriers include building paper, which is either a traditional paper sheet or asphalt-coated or -impregnated to increase strength and resistance to water penetration. This method will be primarily employed to protect against moisture as a drainage layer.
Housewrap, on the other hand, relates to sun-plastic sheet materials which are wrapped around a house or building to protect against moisture penetration. Housewrap may also reduce air infiltration.
Housewrap is typically more expensive than building paper, and some home systems may employ water-resistive sheathing such as rigid foam board. This method can be a weather-resistant barrier that eliminates the need for building paper or housewrap.
