When most people think of insulation, they picture batts in a wall cavity. That's only one option. 🏡
We recently had our first go with Versi-Foam® spray foam insulation. The building industry is constantly evolving, and a big part of building is understanding what products are available and where they work best.
What stood out with this product was how it expands into gaps, corners and uneven surfaces. Instead of cutting and fitting individual pieces, the insulation is applied in place and forms a continuous layer.
According to the manufacturer's data, it has an R-value of 7.7 per inch (25mm), a closed-cell content greater than 90%, and does not contain VOCs, CFCs, Penta-BDEs or urea formaldehyde.
This is the closed-cell version of spray foam insulation. In simple terms, that means the foam forms a denser structure that resists moisture movement, which can be an important consideration depending on the application.
In practical terms, it's designed to slow down the movement of heat through a structure. 🥵 The way the foam expands also helps fill the small gaps and irregular spaces where heat can often find its way through.
We also found the VOC information interesting. VOCs (Volatile Organic Compounds) are chemicals that can be released into the air from some building products, so it's good to understand what's in the materials we're using and how they perform. 🌿
Always something new to learn in this industry.
