Spray Foam Maintenance Tips For Homeowners and Contractors
Spray Foam Maintenance Tips
When it comes to home insulation, few products are as effective or cost-effective as spray foam. This highly energy efficient product is a popular choice for new and existing homes, helping homeowners reduce their energy costs by creating an air barrier that prevents unwanted heat loss or gain.
In fact, a recent Insulation Contractor reported that spray foam insulation can save up to 20% on home energy bills. But, like all other types of insulation, it requires regular maintenance to function properly. This article will provide contractors with valuable Spray Foam Maintenance Tips to ensure they are able to efficiently apply their spray foam insulation each day.
Unlike other types of roof insulation, spray foam insulation requires a full application to the entire roof area. This is because it expands to fill external wall spaces, creating a thermal envelope around the entire structure of the home. This helps keep HVAC systems working more effectively and protects against moisture that can damage timber structures, leading to the need for costly repairs.
Spray Foam Fire Resistance: How Safe Is It Really?
However, spray foam also produces harmful fumes during application and requires the homeowner to vacate the property for 24 hours. It can also hinder ventilation and increase condensation in properties, especially those with thatched roofs and listed buildings, potentially leading to damp and rot. It is also difficult to remove from older timber structures, meaning it can affect the resale value of properties.
This is mainly due to the ‘blowing agent’ that is used to make the spray foam expand, which contains hydrofluorocarbons with a very high ‘Global Warming Potential’ (GWP). Keeping these chemicals in use is not only damaging to the environment, but it can also reduce the effectiveness of the insulation. This is why it is important to keep your spray foam equipment clean and properly inspected on a daily basis to avoid spray gun clogs and pressure fluctuations.
