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 Henderson and Rusk County.

Henderson is the seat of Rusk County and, like Longview and Kilgore nearby, grew explosively during the 1930s East Texas oil boom — one of the largest oil discoveries in U.S. history at the time — and that boom-era construction still shapes a meaningful share of the city's older housing stock. Homes built during and shortly after the boom commonly carry thin original insulation typical of 1930s-50s construction standards, if they were insulated at the time at all beyond basic wall sheathing. Henderson sits within the same East Texas pine forest belt as Nacogdoches and Lufkin, with dense tree cover trapping humidity close to the ground through much of the year. The city's growth has been slower in recent decades than the DFW or Austin metros, so newer, better-insulated construction makes up a smaller share of the overall housing stock here than in faster-growing Texas cities — meaning the oil-boom-era housing stock's insulation condition matters more to Henderson's overall energy-efficiency picture than it would in a city with more recent turnover.

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.
