What are the pros and cons of spray foam insulation?

All across the country, homeowners are looking for was to get the most from the air conditioning and heating system, including here in Texas. One of the best things we can do is insulate our homes, and the latest insulating technique is spray foam insulation

Spray foam insulation isn’t all that new, it has been on the market 1986 and used in new builds for better comfort and energy efficiency. In recent years, homeowners are using it to update their existing homes. Spray foam insulation is ideal for retrofitting attics, crawl spaces, and walls. 

Spray foam insulation doesn’t just insulate a home. It provides barriers against air and vapor too. This results in ultimate energy efficiency, easing the workload for HVAC systems, thus using less electricity or gas. Among the pros of using spray foam insulation: 

  • air leakage minimized
  • air-tight seal eliminates heat loss
  • improved home energy efficiency 
  • lower energy bills
  • fits in corners, cracks, crevices of attics, flooring, roofs, walls
  • higher R-Value over other insulation materials  
  • moisture reduced
  • air drafts eradicated

It is in the long run that spray foam insulation benefits are appreciated as the utility bills drop from improved energy efficiency. Each year with spray foam insulation works toward the ROI expected. 

Spray foam insulation cons is the premium expense of installation. The upfront cost is an investment, so when budgeting is a concern, this isn’t the best product. 

Should I spray foam my attic?

Spray foam insulation comes in closed cell or open cell, that is the small bubbles that create the foam. because of the difference between the small bubbles (cells) that make up the foam. The open cell spray foam insulation has open cells, is more flexible, and has a lower R-Value than closed cell spray foam insulation. Closed cell spray foam insulation has closed bubbles that are pressed together to keep air and moisture out, a more rigid material with a higher R-Value. 

With that lesson in spray foam insulation choices, yes, you can have your attic treated with spray foam insulation. The general recommendation of spray foam insulation contractors is if you choose to use spray foam insulation in the attic, go with the open cell type.  Open-cell spray foam insulation will insulate, but also allow your vented attic to breathe, which is needed to keep moisture at bay. 

Is it better to insulate attic ceiling or floor?

Well that is all going to depend on the attic’s purpose and use.  The idea of spray foam insulation, any insulation actually, is to minimize energy waste and make your home comfortable. This means we want to protect the volume of the house we use, so the less volume, the less energy. With this in mind, you have three suggestions with this question: 

  • If your attic will be used as a room, you want it to be cooled and heated. In that scenario, insulate the roof only. 
  • If the attic is not going to be used for anything more than storing holiday decorations, baby books, and old sporting equipment, then insulate the flooring to keep the heat in the living quarters of the house. 
  • The better solution would be to insulate both. That would keep the air/heat downstairs in the living quarter and keep the outside cold/heat outside. 

Can you over insulate a house?

Believe it or not, yes!   Properly insulating your home has a positive impact on your monthly utilities and the environment. The more energy efficient your home is, the less energy you’re using and that’s good for you and the world at large. 

Installing spray foam insulation will seal your home’s interior tightly, making it air resistant. However, when there is too much insulation, moisture is generated between the layers and mildews, turning to mold. Additionally, an over-insulated house is difficult to get a consistent temperature and lowers the air quality you’re breathing.

How long does spray foam insulation last?

According to the International Association of Certified Home Inspectors, spray foam insulation has a lifespan over 80 years, as does house wrap insulation and wrap tape. Spray foam insulation vs foam board, the lifespan of the foam board beats it providing up to one hundred years. When spray foam insulation or fiberglass is compared, the lifespan of the fiberglass wins with a longer lifespan up to 100 years too. 

When considering a spray foam insulation for home, check with your mortgage company first. What does spray foam insulation and mortgages have to do with each other? Sealing the roof space with spray foam insulation can restrict air circulation to the decking, rafters, and roof. With restricted air, condensation forms and the decking and rafters will rot, especially so with closed cell spray foam insulation.  With this possible rotting wood in mind, a mortgage company foresees difficulty in holding a mortgage 25 years or longer on a property that could have mold issues later. Call (817) 588-2050 today for your spray foam insulation needs in Arlington, TX.
