Spray Foam Insulation Contractors in Decatur, Illinois
Unless something is not right, you do not think about insulation. In fact, you have probably blamed your HVAC system for not working right when it is not the system at all.
So what should you do? Have your insulation checked out. If you need new insulation, the Department of Energy recommends insulation with an R-value rating of R-49 or higher for the Decatur, IL area. Call Illinois Spray Foam Insulation at (217) 516-3717 for a free estimate.
What Is an R-value Rating?
An R-value rating is a measurement of how well a barrier resists the flow of heat from one place to another, in your case from the outside in, or from the inside out. The higher the R-value rating, the better it performs.
R-49 is hard to achieve unless you use spray foam insulation. Spray foam can reach an R-49 rating almost without breaking a sweat, which is why it is considered the best insulation for the Decatur, IL area.
Open Cell vs. Closed Cell Foam Insulation
Spray foam insulation comes in two forms: open cell foam and closed cell foam. Each performs well, and each has its own benefits. Most attic insulation installers use spray foam, and either type can be used in an attic installation. Some installers prefer fiberglass or cellulose, but these are not nearly as effective in an attic or crawl space insulation installation. Fiberglass and cellulose are better suited to interior and exterior wall installations.
Other Insulation Options
There are plenty of insulation types to choose from. Here are the most common options in ranked order of R-value, highest to lowest:
- Closed cell spray foam
- Open cell spray foam
- Polyisocyanurate (foil-faced)
- Polyurethane board
- Polystyrene board
- Cellulose
- Mineral wool
- Fiberglass
And we can install ANY type of insulation you want. Whether you are looking to keep costs down, need to soundproof a room, or want to keep dust, dirt and allergens out, we have the insulation you need. Even though spray foam is the best insulation for your Decatur, IL home or office, we will gladly install what you prefer, including blown-in and cellulose insulation.
Spray Foam Insulation Cost
The initial cost of spray foam insulation is higher than other options, but the benefits outweigh the cost over the long haul. It would be impossible for us to give you an honest estimate without knowing more about your project. That is why we ask you to call (217) 516-3717 or send us a quote request.
