New air infiltration experiments show that wall wrap can significantly improve the energy efficiency of a home.
Air infiltration and air leakage has been identified by the Building Science Corporation and the Australian Government as an important issue that needs to be addressed when building a home.
The Australian Government website www.yourhome.gov.au (Chris Reardon 2013) reports "air leaks are year-round issues: in winter, they allow valuable hot air to escape and unwanted external cold air to enter; in summer, the reverse occurs."
According to the Building Science Corporation website (John Straube 2012) "Stopping air is the second most important job of a building enclosure".
"Next to rain, air leaks through walls, roofs, and floors can have the most damaging effect on the durability of a house. Uncontrolled airflow through the shell not only carries moisture into framing cavities, causing mould and rot, but it also can account for a huge portion of a home's energy use and can cause indoor-air-quality problems."
