Open Cell vs. Closed Cell Insulation: What’s Best for You?

If you’re considering spray foam insulation for your Winnipeg home, you’re making a great choice. Spray foam insulation is one of the best options available for keeping your home warm in the winter and cool in the summer, while simultaneously decreasing your electricity bill. Before you pay to have it applied, however, make sure you understand the difference between open and closed cell insulation.

Open cell insulation is foam that consists of countless tiny cells that aren’t completely closed. Air then fills in all the open space left available. The end result is a foam that’s softer than closed cell insulation. While It can be an option, open cell insulation really isn’t appropriate in Winnipeg, where it often gets very cold and where the atmosphere can be quite dry.

On the other hand, closed cell insulation is perfect for the climate here, and one that Above All Insulation specializes in. Closed cell foam is also made up of tiny cells, but they are completely closed and packed tightly together. Inside these cells is a gas that helps the foam to expand, providing greater insulation. As a result, closed cell foam is much heavier than its open celled counterpart. This makes it much stronger, too.

Closed cell foam also comes with a greater R-value, which is the material’s ability to resist heat loss. Typically, it performs over 20% better per square inch than open cell foam. It’s also far superior when it comes to resisting water vapour and the loss of air. With closed cell foam, you’ll also get increased wall racking strength and improved impact resistance.
