XPS and Foam Sealant Test Results
XPS and Foam Sealant insulation is rigid foam board sealed in place with one part can foam to make it virtually airtight. This system is used when you want to get the airtightness of spray foam with DIY techniques. Though not economically advantageous for all projects this can be a good fit for smaller projects. Let’s take a look at how it performed on my house.
The results of the test are arranged into 3 segments:
- Test setup - shows how the test bay was assembled.
- Normal Winter - shows the test bay performance against the control bay on a moderately cold winter night with no wind.
- Extreme Winter – shows the test bay performance against the control bay on a day that is either extremely cold or has a 20 mph wind. The process used to simulate an extreme winter day is to depressurize the space to 50 Pascals, a pressure 5 to 10 times normal pressure. Depressurization with a blower door is commonly used to locate air leaks in a structure.
