Buyer’s Guide to Spray Foam Insulation

If you are a homeowner or business owner putting insulation into a new building or having to re-insulate your home or business, it pays to know the benefits of spray foam insulation. The best insulation for homes and business on the market today is spray foam insulation. Spray foam insulation has been around for years, although one of the newest and best innovations in the field is that of RetroFoam spray foam insulation. There are a number of benefits provided by spray foam insulation that other forms of insulation simply do not provide. Homeowners who make an investment in spray foam insulation are investing in the future of their home as well as in the health and comfort of their families. Business owners who have this type of insulation installed are protecting their employees, customers, vendors, and their business. It is a wise decision that pays off for years to come.

Key benefits to spray foam insulation include properly sealing a building to prevent moisture and air infiltration, adding strength to the building’s structure, enhances comfort, and improves the fire safety of the building. Spray foam insulation helps improve the building envelope. The building envelope is the compilation of various construction materials and design methodologies that help to control the moisture, temperature, and passage of air into and out of the building. Where other styles of insulation are crammed between walls and packed into crawl spaces, it does not have the same tight fit as spray foam insulation.

These places often brought about issues with condensation, radiant heat transfer, and excess air ventilation. The air ventilation is necessary as it provides breathing room for pipes, electrical conduits, and seasonal weather issues. The problem with that ventilation is that it brings in more moisture and pollutants from the outside. Those voids created by the ventilation techniques also provide ample space for insects and rodents to enter into the home. When we have the heat or air conditioning on, that extra ventilation makes our HVAC units kick into overdrive as air passes in and out of the ventilated space, leak into the rest of the home.

The air ducts in our homes often run along these ventilated spaces. What that amounts to is an average 10% loss in heating or cooling power. This is due to an effect referred to as radiant heat transfer. It is basic thermal dynamics, that there is no such thing as cold—cold is merely the absence of heat. Heat strives to be wherever it is cold. So, if the outside is warm, you have warm air transferring into the ducts due to these ventilated spaces. If the air outside is cold, warm air from the ducts is escape to try and warm that surrounding area. That amounts to a typical energy cost increase to heat or cool a home of somewhere between 10 and 20 percent.

The way the hot sun beats down on the roof through the summer allows these attic and crawl space ventilation points to build up more heat. In the winter, the winds blast the roof and snow and ice sit atop and keep the roof cold. Those changes to temperature make it uncomfortable for those of us who live in the home. We turn up the heat or increase the output of the air conditioner unit. This then puts extra work on those units, causing them not only to eat up more in energy costs, but also wear away sooner than they should requiring more maintenance and perhaps earlier replacement than necessary.

There is no argument that the home needs to “breathe.” However, there is a way to do it right. Do not rely on the cracks, gaps, and other uncontrolled air leaks of traditional construction. Instead, the house can be built tight and right, having an overall lower cost of ownership. Spray foam insulation can help make these doable. It can work with seasonal expansion without sacrificing air seal within the home. Spray foam insulation helps keep the house stronger and allows for a higher level of indoor air quality within the house.
