The Five Benefits of Spray Foam

In our day-to-day lives, there are simple luxuries that typically go unnoticed, but are greatly appreciated. This feeling can come from a smooth car ride, an uneventful day or your favorite pair of jeans that fit just right. You can achieve a similar feeling in your home and spray polyurethane foam (SPF) insulation is an important reason why. When you walk through your home, a consistent temperature from room to room is one of the small but appreciated pleasures. Many homeowners agree that investing in spray polyurethane foam brings the same delight as a smooth car ride or your favorite pair of jeans.

When you choose spray foam, you invest in durability, longevity and comfort. These characteristics can seamlessly turn a house into a home. Spray foam offers outstanding performance and there are several characteristics which makes it so highly regarded among homeowners. Here are five notable benefits of using SPF insulation:

Air Sealing

Air leaks can waste up to 40 percent of the energy used to heat and cool single-family homes.1 SPF insulation is applied on site and is uniquely capable of efficiently sealing holes and cracks throughout the home because it expands as it is applied. A tight building envelope helps prevent nuisances from cold drafts to insects and pollen from infiltrating your home where it is applied.

Holes and cracks can allow more than outside air to enter your home. Closed cell SPF is also classified by FEMA as “highly resistant to floodwater damage”, which helps protect from moisture, leaks and even in cases of flooding.2

Energy Savings

What may come as a shock to most is that insulation has a three times greater impact on the average home’s energy usage and comfort than windows and doors do.3 The U.S. Department of Energy estimates that 56 percent of the energy used in homes goes towards heating and cooling. Spray foam is a powerful insulator. If every single-family home in the U.S. used SPF, Americans could save up to an estimated $33 billion in energy needs each year. SPF insulation helps keep conditioned air from escaping the home. Having an effective thermal envelope reduces the workload for HVAC units – so they don’t have to work as hard to keep homes comfortable through New England winters and Arizona summers.

Fresh Indoor Environment

SPF insulation can help you achieve a clean, fresh feeling in your home by closing air leaks and gaps. The closure of air leaks and gaps manages moisture and humidity, as well as pollen, which can help protect you during allergy season. In high peak insect seasons, there’s nothing worse than a swarm of fruit flies in your fresh produce or waking up to mosquito bites. SPF’s insulation seal helps reduce insect intrusions inside of your home no matter how big or small.4

Long Life-Span

This modern insulation choice is highly regarded for its durability; according to the International Association of Certified Home Inspectors, SPF can last for more than eighty years. This typically allows homes and businesses to enjoy the perks of SPF insulation for years and years before re-insulation. SPF insulation is unique as it sticks to the surface to which it is applied, which keeps it from sagging or settling over time. The investment in SPF can increase savings over the course of its lifetime by reducing the need for frequent repairs and replacement.

Roof Strength

The home is only as strong as the sum of its parts. Roofing systems are one of the most vulnerable areas of a home during a severe thunderstorm or derecho. During these storms, roofs are often subject to damage from wind uplift. While no system is foolproof, SPF minimizes the risk of wind uplift to roofs because it adhesively bonds the roof deck to the trusses and rafters, essentially gluing the roof to the home.

If you want to achieve maximum comfort where it matters most, invest in the right materials. These five characteristics show why the application of spray polyurethane foam when building or renovating your home shouldn’t leave you second guessing.
