Dive into the best practices for using spray foam to build energy-efficient roofing systems.  

Across the globe, heat waves are becoming more common. The Center for Climate and Energy Solutions reports that “in cities across the United States, the average rate of extreme heat events increased from two per year in the 1960s to ten per year between 2010 and 2020. Additionally, as of 2024, the average length of heat-wave season in the U.S. has increased by 46 days since the 1960s.” And this trend is unlikely to change in the next few years. In fact, looking ahead there are predictions that “the annual number of days with a heat index above 100°F will double and days with a heat index above 105° F will triple, compared to the end of the 20th century.” 

From rising energy costs to heat-related illness in urban areas, this increasing frequency of extreme heat waves creates unique challenges. One of the big ways we can work to protect our communities through these changing weather patterns is by building with materials that are uniquely suited to handle the heat – materials like spray foam roofing. 

Why spray foam?  

Spray foam roofing is known for its exceptional energy saving capabilities as well as its low environmental impact. How does spray foam save energy and the environment? Spray foam roofing not only acts as a roof but also added insulation. This reduces the amount of heat transfer happening through the roof, meaning that homes stay cooler in the summer and warmer in the winter. Some reports indicate that “spray foam roofing can reduce energy costs by up to 30%.” 

Not only does this energy-efficiency make buildings more comfortable and save owners some money, but it also makes spray foam a very eco-friendly choice. By reducing the amount of heating and cooling that must be done to maintain a comfortable interior environment, spray foam lowers greenhouse gas emissions, helping our entire planet stay more comfortable.  

Working with spray foam this summer 

With all these benefits, it's no wonder that owners who are struggling to beat the heat this summer would be interested in getting a spray foam roof on their home ASAP. There are a few strategies that the experts at Enverge recommend roofers adhere to in order to successfully and safely install spray foam in the warm season:  

• Keep your crew safe: The most important part of working with spray foam in the summer is making sure your people stay safe. Consider investing in cooling vests, portable fans and other equipment that helps prevent heat stress. Additionally, ensure your team is properly trained to recognize the signs of heat-related illness and know proper protocols in the case of an emergency.  
• Make sure your materials stay cool: Heat can wreak havoc on formulas and chemicals if not properly monitored. Make sure you are storing your spray foam products according to manufacturer’s instructions, even if that means investing in insulated boxes or coolers to keep them in the optimal temperature range. 
• Double and triple check your equipment: Heat can also affect your equipment. Sometimes the issue is obvious, like a spray gun overheating, and sometimes it's more subtle, like a material thickening in the heat and clogging a component. To avoid both, make sure your equipment is properly calibrated and maintained for the temperatures. 
• Adjust your operations: You may need to adapt your application techniques when things get hot. This can look like applying thinner passes of foam for better heat dissipation, increasing the distance between your sprayer and the substrate and timing your work for the cooler mornings and evenings (avoiding the heat of midday). 
• Keep the substrate in mind: Remember that the heat is not only impacting the product you’re putting down, but also the substrate you are putting it on. Substrates that are too hot can cause issues with adhesion and performance. A good plan is to bring an infrared thermometer to check temperatures to ensure anything you install adheres and cure correctly.  

These are just some of the tips and tricks the Enverge team has for installing spray foam in the heat. If you’re planning on helping clients stay cool with a spray foam installation this summer, make sure to check out the whole article!

As the Artemis Rocket took astronauts to new heights, this spray foam installation on Artemis Living took senior living to the next level.  

Located in the White Mountains, Littleton, New Hampshire is a quaint town known for producing author Eleanor H. Porter. With the motto of Be Glad, it’s easy to see why this might be the community you choose to retire in. And if you’re thinking of retiring in Littleton, there’s a new community that elevates senior living that’s perfect for you.  

Artemis Living is a senior living facility with a focus on holistic wellbeing set to open in 2026. The goal of the team behind Artemis Living was to integrate wellness practices, such as physical strength and personal care, into the daily life of their inhabitants. To do this, a high-performance building that balances structural safety and inhabitant comfort was a must. And to achieve that, they worked with Blue Lodge Insulation to install advanced Enverge Spray Foam products.  

The Blue Lodge Insulation team was able to ensure that the Artemis Living building would maintain stable temperatures, minimal drafts and healthy air quality by using Enverge products. They first installed two inches of Enverge One Pass closed-cell spray foam under the slabs of the structure. Then three inches of the same product were applied to exterior walls both as insulation and an air barrier. Last but not least, 14 inches of Enverge EasySeal open-cell spray foam was put on the underside of the roof deck, eliminating voids in roof cavities and achieving a high R-value.  

Benefits of this continuous system include high-energy efficiency, strong thermal resistance and air-tight seal performance. Not only do all these benefits align with the mission of wellness behind Artemis Living, but they also promise lower long-term operating costs by reducing HVAC loads. As an added bonus, the open-cell foam used on the roof reduces sound echoing, contributing to the tranquil environment that the Artemis Living team aims to cultivate.

Hear from Mark Hearn of Enverge about why spray foam is more than just insulation. 

Back in March, we hosted a soundstage at the Spray Polyurethane Foam Alliance’s 2026 show. One of our guests was Mark Hearn from Enverge, a company we just welcomed to The Coffee Shops™ less than a month ago! In the interview, Mark, who is Enverge’s mid-Atlantic area sales manager, explained the importance of understanding that spray foam is more than just insulation, it’s an entire system.  

He explained, “Spray foam is not just an insulation component. Spray foam is really part of a system... We're not necessarily in the insulation business or the spray foam business. We're really in the building performance business.” By thinking about spray foam as a part of the larger building system, you can go beyond just building a thermally energy efficient space and also build a space that is comfortable, protective and healthy.  

The key to achieving this well-rounded result is education, something that the team at Enverge works hard to connect contractors, designers and even home and business owners to. Mark explained, “We're talking to a lot of contractors about using spray foam as a system. And those contractors then connect with the architects that they're working with, their building code officials that they're working with and even some of the homeowners to talk about using spray foam to take a building to the next level, both in terms of energy efficiency as well as air quality, comfort and safety.”
