The right insulation doesn’t just protect your home from drafts. It also presents a viable solution for going green. So if you’re thinking about upgrading your house’s insulation system into SPF, here are some important things that you should consider. These are some of spray foam’s major eco-friendly qualities.
Efficient Energy Conservation
Spray foam or spray polyurethane foam (SPF) gets its most environmentally friendly trait from its efficiency on energy conservation. It saves about 50% of it in a year and can help build greener homes because of it.
Approximately 56% of your home’s energy is used to either heat it up or cool it down. We do this to balance out the varying temperatures of your region’s unpredictable weather. However, 30% of that heat escapes through the walls and 20% is radiated away from the roof.
SPF’s main environmental appeal comes from its high R-value. If you don’t already know, R-value is what measures an insulation’s ability for thermal resistance. It involves the capacity to negate heat transfer from one area to another. With an R-value that ranges from 3.8 to as high as 7+ per inch SPF can reduce heat escaping through walls and attics in winter, making you turn down the heating system to consume less energy. And when the heat and humidity of summer is trying to intrude, your foam will help keep it out allowing your central air system to maintain desired temperature and humidity levels to keep you comfortable with less run time for the system.
Air Sealing Qualities
Spray foam expands upon contact to any surface so it’s able to fill those little gaps, corners and edges between building materials and effectively seal the home from unwanted air infiltration. This becomes especially useful in warmer weather when hot air from the outside usually makes us overwork our AC systems to avoid fluctuating temperatures and humidity levels indoors. This air sealing benefit of foam also helps keep contaminants like dust, pollen, and other allergans out of your home so you can protect your home’s air quality.
Ultimately all of this helps to cut back on energy consumption and require less reliance on power plants and therefore reduce your home’s carbon footprint. And if (or when) you make a move to include solar power for your home SPF will help because of the reduced energy load the building will require. The less consumed requires less to produce.
Organic and Recycled Options
Bio-based spray insulation is a popular choice among many eco-conscious homeowners. While regular SPF is made from isocyanate and polyol resin, bio SPF comes from sustainable resources like soybeans, castor beans and even cashew shells. Oil from these plants are extracted and used in place of portions of the resin to reduce the petroleum needed.
Recycled bottle programs reduce new petroleum usage in foam production and additionally eliminates landfill waste. Hundreds of millions of plastic soda and water bottles have been diverted from landfills and into SPF to save energy for years to come.
What’s great about these type of spray foam is that they maintain the foam’s R-value and other useful characteristics. This use of renewable and recycled resources help architects, contractors and home owners earn additional LEED credits and points toward green certifications for buildings.
Less Frequent Upgrades
Finally, spray foam lasts up to 8 decades. That’s 80 years of continuous use without the need for replacement. With this in mind, you won’t need to upgrade your insulation. That means there’s less need for you to spend on environmentally impacting resources that are needed to replace your home’s insulation. These would include car rides, materials needed to blow the foam and electricity from coal driven plants.
So if you are thinking to update your home’s insulation, try out spray foam. It’s got some green loving perks that goes wonderfully well with today’s modern living. And will benefit generations to come.
