Why Spray Foam — And Why Closed-Cell Specifically
No sales pitch, just the building science. How closed-cell foam works, what the numbers mean, and what the code requires.
An informed client is our easiest client — because closed-cell spray foam wins on the facts. These guides cover the questions we answer every week: how the product actually performs, how to read R-value claims honestly, and what the Ontario Building Code requires from an insulation assembly.
Read up, then bring us the hard questions. If closed-cell isn’t the right answer for your project, we’ll tell you that too.
