The Significance of Water Vapor Barrier Elastomeric Foam
Water vapor barrier elastomeric foam is at the cutting edge of insulation technology, offering a vital defence against moisture. It has a permeability rating as low as .016 perm with 10 mils/min. of coating. This makes it an impermeable choice8 designed to shield buildings from the harm caused by water vapor.
The success of insulation materials relies heavily on their ability to block moisture vapor. This is measured in either g/m2·day or g/100in2·day8. In British homes, where staying warm is essential, placing these barriers inside is key to controlling condensation8. However, in places that need more cooling, the barriers are placed outside, showing the foam's flexibility in different climates.
These barriers come in three types: Impermeable, Semi-permeable, and Permeable, based on their perm ratings89. For example, Advanced Polyethylene vapor retarders meet the ASTM E 1745 standard. They offer less than 0.3 US perm, making them ideal for careful use8.
In modern building rules, vapor barriers are a requirement, not just a suggestion, in places like the U.S., Canada, and the UK8. They are crucial in damp-prone areas like basements. In existing homes, special paints help protect against vapor9.
The use of water vapor barrier elastomeric foam is not just about controlling temperature and saving energy. It also helps maintain a building's structure. By preventing corrosion and decay caused by dampness, elastomeric foam keeps buildings strong against time and weather.
