Spray foam insulation creates an air seal and insulation layer in a single application — it expands to fill gaps and adheres to the surrounding surface, eliminating air infiltration that other insulation types can't address. Contractors in our network install both open-cell and closed-cell spray foam for homeowners and commercial properties throughout Tyler and Smith County.

Tyler is the seat of Smith County and the commercial center of East Texas, built across rolling hills covered in pine and dogwood. The city grew wealthy first from 1930s oil and later from the rose-growing industry that still earns it the nickname “Rose Capital of America,” and that layered history shows up directly in attic conditions: brick colonials from the Azalea District and Old South Tyler era often have shallow attic spaces with only a few inches of original batt or loose-fill insulation from the 1940s-50s, while ranch homes from the 1960s-80s off Old Jacksonville Highway typically have somewhat more but still below-code coverage. Tyler's humid subtropical summers push attic temperatures well past 130°F on sunny July afternoons, and undersized insulation in these older homes translates directly into high AC run time. Newer subdivisions pushing north along Loop 323 toward UT Tyler use modern blown-in fiberglass or cellulose meeting current energy code, giving Tyler a genuine split between chronically underinsulated older housing stock and adequately insulated new construction.

Open-Cell vs. Closed-Cell Foam

Open-cell foam has a lower R-value per inch (around R-3.5) but is less expensive and expands aggressively to fill cavities. It's vapor-permeable, which makes it appropriate for some wall applications in this climate. Closed-cell foam has a higher R-value per inch (around R-6-7), is rigid, and acts as a vapor barrier — it's the right choice for crawl spaces, exterior walls in high-moisture areas, and unvented attic assemblies. We recommend the right type for your specific application.

Some rooms are noticeably harder to heat or cool than others

Uneven temperatures between rooms, especially rooms above or below an attic, are a common sign of insufficient or unevenly distributed insulation.

Noticeably higher heating and cooling bills than similar-sized homes nearby

This is one of the more measurable signs that a home is losing conditioned air faster than it should — worth a comparison before assuming it's just an old HVAC system.

Ice dams forming on the roof edge in winter, or a hot, stuffy attic in summer

Both point to heat escaping into the attic space rather than staying inside the living area — a classic insulation-and-ventilation combination issue.

When Spray Foam Is the Right Choice

Spray foam is particularly valuable when air sealing is the primary goal, when you're insulating unusual shapes or hard-to-access cavities, when you need insulation in a vented or conditioned crawl space, or when you're doing an unvented attic assembly. It's generally more expensive than blown-in or batt insulation per square foot — we'll tell you when the premium is justified.
