Spray Foam Mistakes

Spray Foam Mistakes

If you’re thinking about improving your home with spray foam insulation, don’t put it off any longer. When properly installed, spray foam insulation is a fantastic investment, as it increases the energy efficiency of your home, provides moisture control and seals air leakages. However, when mistakes are made and the insulation isn’t properly installed, its effectiveness diminishes. That’s why it’s important to have a professional conduct the installation of spray foam in your Vancouver home. Here are some of the most common mistakes that can occur when installing spray foam insulation on your own.

  1. Insufficient coverage. One of the most important criteria for spray foam insulation is that it must cover the entire area, down to every last nook and cranny. If you happen to miss a drafty spot, the thermal regulation ability of the insulation will be compromised. Additionally, if humid air is able to enter, it can potentially cause water damage to your home’s interior.
  2. Ignoring the temperature of the foam. Applying spray foam that’s either too hot or too cold can be extremely detrimental to the quality of the insulation. Cold foam will be too soft and spongy, while hot foam will be brittle and flaky. In both cases, the result is a poor insulator, meaning you won’t get the full benefits of temperature control or increased energy efficiency.
  3. Clogged nozzles. Spray foam insulation has to be applied uniformly over the desired area. However, because the foam is so sticky, it can build up on the nozzle and sometimes clog it. Consequently, the insulation can end up being applied in an uneven manner. If the nozzle becomes clogged, it should either be cleaned thoroughly or replaced altogether, as spray foam that’s applied irregularly doesn’t make for a very good insulator.
  4. Foam thickness. One kind of spray foam, open cell foam, will expand to fill the space it’s applied in, while closed cell foam expands only slightly. Thus, when using closed cell foam, you need to ensure that the coating is consistent and of adequate thickness. If it’s not thick enough, it won’t effectively insulate your home.
