iFOAM is a U.S.-based insulation franchise fueled by the franchising experts at HorsePower Brands. We specialize in spray foam insulation and also provide best-in-industry blown-in solutions, insulation removal, retrofitting and other specialty project services. At iFOAM, we saw an issue with the industry—a lack of quality and trustworthy services and a clear absence of certified training when it came to spray foam. At iFOAM, we’re flipping the script by providing our certified technicians with the best tools, training and products in the trade and bolstering your experience with prompt, timely communication.

"Job completed as estimated."

At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

"Professional, timely and best installers we’ve had. Our installers took to time to get everything fit right. They had their hands full with a few doors and windows, due to bad framing from our construction contractor. Our new doors and windows work flawlessly now."

"Arrived on time as scheduled. They covered floors and railings with commercial moving blankets to protect floors and railings and did all necessary prep work and inspection in attic. Once all prep work complete, they started adding insulation. When all work was done they cleaned up everything and could not tell they were there other than the second floor was now much cooler. Will definitely recommend."

Insulation questions, answered by experts

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.

Spray foam insulation can last up to 80 to 100 years, making your investment worthwhile over the long run. Closed-cell spray foam tends to have the highest durability. Open-cell foam is subject to moisture, which can lead to deterioration. Remember that some spray foams will damage plastic piping, so consult a pro if you have PVC or CPVC pipes.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Even though spray foam insulation typically comes at a higher price point than other insulation types, the benefits make up for the investment. Some benefits of spray foam insulation include:

  • Improved air quality, as this type of insulation helps minimize indoor allergens

  • Easy installation 

  • Lifespan of 80 to 100 years.

  • Added home strength, protecting it from humidity and wind.

  • Additional soundproofing

  • Energy bill savings
