3 More Spray Foam Installation Mistakes to Avoid

Spray foam insulation is a great way to keep your home warm, dry, and comfortable. However, the installation process can be a bit trickier than other types of insulation, especially if you’re inexperienced at working with spray foam chemicals.

Too often, those new to spray foam application make mistakes that render the air seal and insulation less effective. Luckily, these mistakes are easy to prevent so long as the installer takes appropriate precautions.

If you’re thinking about embarking on a spray foam insulation project, read on. Here are three all-too-common spray insulation mistakes to avoid:

1. Starting With Insufficient Structural Knowledge of the Building

In order to create a proper air seal, spray foam needs to fill pretty much every part of the room’s outer wall. If the installer misses any corners or crevices, external air can seep into the space, potentially rendering the rest of the spray foam insufficient. To avoid this mistake, use the home’s blueprints to evaluate the building envelope whenever possible. Carefully planning out where to apply the foam can ensure that no corner is left uninsulated.

2. Apply Spray Foam Chemicals At the Incorrect Temperature

In order to spray, stick, set, and insulate properly, spray foam chemicals must be applied within a certain temperature range. If the spray goes up too cold, it will come out too soft and spongy, resulting in a lower R value. Alternatively, installing spray foam that is too hot can make the substance crusty and flaky. To avoid this issue, look for spray foam kits that feature temperature gauges for the most accurate application possible.

3. Failing to Get Complete Coverage or Adequate Thickness

For best results, spray foam chemicals should be applied in an even, smooth, and complete coat. Spraying at too fast a rate can result in a thinner coating that’s only about 1/2 an inch thick. If this happens, you’ll have to apply a second coat, so don’t rush the process. Similarly, trying to spray too fast or altering your pace can leave gaps in the insulation, which you definitely don’t want.

By avoiding these mistakes, your spray foam insulation will be more effective and efficient. If the whole process sounds like too much to handle, you can always hire experts to get the job done. With HVAC employment rates expected to rise 15% from 2016 to 2026, there won’t be any shortage of people who can help!
