When the storms and tornadoes passed through Missouri and Illinois, many homeowners suffered damage from the high winds and debris impact. This damage exposed structural weaknesses, poor insulation, and poor construction methods.
How Did This Happen?
Many homes in the Arnold and Imperial areas, and in fact all along the I-55 corridor, were originally constructed with styrofoam panels behind the vinyl siding. When that siding blew off in the high winds we recently experienced, that styrofoam sheathing was revealed.
In other words, instead of a sturdy substrate you would hope to find, like plywood or OSB (both strong wood products), they discovered their wood framing had been covered in 4×8 sheets of ½” thick styrofoam.
If you need to repair storm damage, now is the time to upgrade the structural strength of your home, add foam insulation, improve the comfort of your home, and cut down on utility bills – all at the same time.

The downsides of poor insulation
Unfortunately, this I-55 corridor is also where homeowners often say they can hear their neighbors talking outside as if they were in the house. They can hear the highway as if the windows were open. These are the same homes that are hot in the summer and cold in the winter. Poor insulation is to blame.
The foamboard is sold in sheets like plywood. To cover a house in 4×8 sheets, you have lots of them with seams between them. Water and air can pass between the sheets. When the rain passes between the sheets, it can contact the wood studs of the house and rot the studs. Furthermore, half-inch foamboard exacerbates the inefficiency of fiberglass insulation. It allows the noise to easily come into your home, and poor insulation also causes high energy bills.

- Get foam insulation: Gateway RetroFoam will remove inefficient fiberglass insulation and replace it with spray foam or RetroFoam.
- Finish the job: Then your siding contractor will complete the job by installing plywood and siding.
Find out what is behind your siding and get a quote
Do you have styrofoam or plywood behind your siding? While you have your siding contractor on site, ask them to confirm if you have foamboard or plywood behind the siding. (It’s best to check for foamboard at least 3 feet away from the corners.)
If you’d like to know before speaking with a siding contractor, we’d be happy to come out to your home, talk about your insulation options, and inform you if you have plywood or foamboard. Regardless of whether you have plywood or foamboard, invite Gateway RetroFoam to get your discounted quote.
