Updated: Sep 2, 2020

Considering spray foam for your home performance upgrade? Spray foam insulation may not be the most cost effective option for increasing your home comfort and saving you energy all year long. Trust the Hudson Valley’s building science experts at Energy Conservation Services, Inc. to help you find the right insulation solution.


Think You Need Spray Foam Insulation? Think Again

As the go-to building science and insulation experts in the mid-Hudson Valley, Energy Conservation Services, Inc. answers a lot of questions about spray foam insulation each and every day. Many homeowners here in the Kingston, NY area are looking to reduce their heating and cooling costs and stay more comfortable in their own homes by upgrading their outdated insulation.

While spray foam is an excellent solution for many homes suffering from uncomfortable indoor temperatures, it is not always the most cost-effective solution. Here are the details you should consider about spray foam before pulling the trigger on your insulation upgrades — and what other insulation alternatives you should consider.

Understanding Spray Foam Insulation

Just to make sure we are on the same page, let's go over how spray foam insulation works and how it can keep more of your valuable conditioned air inside your home where you need it. Spray foam is a liquid form of insulation that is installed in the interior and exterior walls, attic, floors and crawlspace of a home via a hose. It expands once it leaves the spray nozzle and will harden and cure over time.

Polyurethane spray foam comes in two forms: closed cell and open cell. At Energy Conservation Services, Inc., we install closed cell spray foam for its instant curing properties, increased R-value (resistance to heat transfer), and more environmentally conscious manufacturing process. One of the reasons spray foam has become the top of the line insulation material is its ability to find any holes, cracks, or gaps in a home and seal them up during expansion. Closed cell spray foam is also extremely effective at preventing moisture infiltration, which greatly reduces the risk of mold growth and improves indoor air quality (IAQ).

To Spray Foam, or Not to Spray Foam?

So, when should you consider spray foam, and when should you look at other options? It will likely depend on the goals you have for the installation of your new insulation. Spray foam is extremely effective, but there may be more affordable solutions that still accomplish your home performance goals. Make sure you ask yourself these questions before you make any insulation decisions:

Where is your insulation being installed?

For existing homes, spray foam insulation is most effective to air seal top plates in the attic and the rim joist in the crawlspace. If you are looking to install spray foam in existing walls or attic sloped roof, there may be better options, like loose fill cellulose insulation.

Are you looking to “go green”?

Though closed cell spray foam is more environmentally conscious than the more traditional fiberglass insulation, there are other eco friendly options like Eco-Cell Batt insulation, Roxul and professional grade cellulose insulation.

What are your under-insulation symptoms?

As we mentioned, one of the biggest selling points for spray foam insulation is its ability to provide a proper air seal throughout the home. If you experience indoor drafts, spray foam may be the best way to go. But if you already have a proper air seal in your home, it may be worth looking at other options.

Who is installing your spray foam?

The proper installation of spray foam is absolutely essential to its effectiveness. Spray foam application is not a DIY project, and the popularity of spray foam has led to many inexperienced home performance contractors trying their hand at it. When you trust the building science experts at Energy Conservation Services, Inc., you can rest easy knowing your spray foam will be installed to the exact calculated thickness and in the necessary areas for increased energy savings and home comfort.

With the right insulation for your home, you can enjoy a long list of benefits in every season, for years to come. With proper insulation, you can reap benefits like:

Reduced year round energy costs

Less wear & tear on heating & cooling equipment

Decreased indoor drafts

Stable indoor temperatures

From new construction to historic homes, each home presents its own unique challenges and needs, which is why choosing the right home performance contractor is integral to keeping your Hudson Valley area home as energy efficient, environmentally friendly, and comfortable as possible. Keep cozy during the cold New York winters, and don’t sweat the humid New York summers when you partner with the building science experts at Energy Conservation Services, Inc.
