"We’re building a new 1000 SF home and these guys did a great job. Easy to communicate with, showed up when they said they would and knocked the entire job out in a day. City insulation inspection passed without any issues the next day. SPF was even kind enough to upgrade to higher R-value insulation in some of our 2x8 walls at no added cost. Highly recommend!"

"Sergio and his crew timely completed a complex insulation installation. Near Me Insulation LLC gets highest marks for flexibility in terms of traveling from Burlington to Glacier and completing the work with the highest skill level. The inside of my Ski Barn in Glacier has a height of 35 feet at the peak--several rooms with outside walls needed insulation. Sergio and crew also wrapped pipes and replaced window flashing with great care and expertise. Highly recommended contractor--reasonable price."

Insulation questions, answered by experts

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.
