Since 1975, Slagel Insulation has been spraying polyurethane foam. Starting life as a one-man operation, we’ve grown into a family owned company with many years’ experience in the insulation and commercial roofing industries.

We are a bit different than most other insulation contractors in that we insulate with spray foam exclusively. We do not offer fiberglass or loose-fill blown-in insulation (cellulose) services. This allows us to focus on and develop our techniques and expertise in spraying foam.

Foam insulation is the most effective form of insulation available, and is a great fit for any job calling for thermal protection. The most common projects we see are new home construction remodels additions, basements crawlspaces, garages and large out-buildings (shops warehouses machine sheds). We specialize in metal buildings (both wood post-framed and steel structured) and have proven designs for walk-in coolers freezers.

We spray both open and closed cell foam. They each have their advantages and, depending on project requirements, one will be a better choice than the other. However, closed cell is the most common product we use, as its ability to stop water-vapor, add structure rigidity and provide higher R-values per inch usually means it is the best fit.

We service most of central Illinois, generally working within 60-80 miles of our shop located in Fairbury, IL. If the project is large enough, we will travel farther, and have several times even worked out of state!

Many jobs are similar in certain aspects but there are times when we are presented with a unique project. In either case, we offer design consideration for each specific job and can analyze a technical job through each step, providing on-site service to determine what application is best for you.

Quality and service are top priorities for us, and as a small company these are more than hollow promises. We have less than 10 employees and our spray foam crew leader has over 20 years of spraying experience – you will not run the risk of having novice, inexperienced workers in charge of your next insulation project. The results speak for themselves: with over 40 years’ history and our attention to quality and detail, it’s no surprise that word-of-mouth is single-handedly our largest source of new clients.

So call us today – let us show you what so many others have come to learn, how there really is no comparison to insulating with anything else! Spray foam insulation – “the best there is.
