Understanding Spray Foam Insulation

Spray foam insulation is a top pick for many. Homeowners and builders love it for keeping homes and buildings well-insulated. It's a mix of chemicals sprayed on surfaces. When it touches the surface, it expands and becomes hard. This creates a strong seal. It stops air from leaking out or coming in, keeping the indoor space comfy and using less energy.

What is Spray Foam Insulation?

Spray polyurethane foam (SPF) acts as a barrier against the outside. It starts as a liquid that craftsmen spray on. Then, it quickly expands and becomes a hard layer. This insulating method is really effective. In just one inch, it can trap heat well, with a value of R-3.5 to R-6.5. This makes it a smart choice for covering attics, walls, and crawl spaces in homes.

Types of Spray Foam Insulation

There are two main kinds of spray foam: open-cell and closed-cell. Open-cell has a softer touch and bends more, giving it an R-value of R-3.5 to R-4.5. Closed cells are tougher and denser, with a higher R-value of R-6 to R-6.5. These both keep air out and handle water well, making them perfect for many places in your home, like attics and crawl spaces. They are strong choices for stopping leaks and keeping your house at a good temperature.

Longevity of Spray Foam Insulation

This kind of insulation lasts a very long time because it keeps its shape. Normal insulation, like fiberglass, lasts about 15 to 30 years. But spray foam keeps going as long as your house is up. This is because it doesn't droop or lose its insulating powers over time. It's a choice you can make once for comfort and saving on energy bills.

Compared to normal insulation, spray foam can last 80 to 100 years. Closed-cell spray foam lasts the longest because it is very sturdy. It keeps its shape well, lasting for many generations.

Factors Affecting Spray Foam Insulation Lifespan

However, some things can make spray foam last less long. Here are a few issues:

  • Not applying the right thickness of the foam.
  • Failure to remove old insulation before adding spray foam
  • Not cleaning substrates and allowing them to dry fully.
  • Spraying foam over old insulation
  • Leaving holes and gaps in the insulated space
  • Installing on a surface that is too hot or cold

To make spray foam last, it's key to have it put in by pros and avoid common mistakes. VB Insulation is top-notch because it's durable and demands little upkeep when installed right.

Spray foam insulation has many benefits that homeowners and builders love. It is great at keeping your home's energy efficiency high. It stops air from getting in or out, making your home stay at a steady temperature. This means you won't need to use your heater or AC as much, saving you money.

Moisture Resistance

Another plus of spray foam is how well it keeps moisture out. Its tight seal blocks water, stopping mold and mildew from growing. This keeps your insulation in good shape for a long time.

Air Sealing

Getting spray foam insulation installed the right way is key for it to last long and work well. VB Insulation thinks it should only be done by trained professionals.
