Improving energy efficiency and indoor comfort comes down to using the right insulation system—and just as important, working with a spray foam insulation company in Bastrop, TX that understands local building needs and climate conditions. Spray foam offers some of the highest performing results, but only when it’s installed correctly and matched to the structure’s exact requirements.
H&R Foam Insulation LLC has helped homeowners, builders, and businesses across Central Texas improve their structures by combining proven spray foam methods with real-world performance insights. This article explains how to get better insulation results, how to avoid common pitfalls, and what to consider before moving forward with any insulation project.
Start with Choosing the Right Insulation System for Texas Conditions
Homes in Bastrop face high summer temperatures, occasional winter freezes, and significant humidity year-round. These elements place extra pressure on insulation performance. Many homes lose cooling through attics, crawl spaces, and poorly sealed walls. Getting better insulation results starts by assessing the structure’s envelope and applying spray foam where it prevents the most air loss.
Closed-cell spray foam works well in spaces exposed to moisture or requiring structural support, like crawl spaces or barndominium walls. Open-cell foam provides excellent thermal performance and sound absorption for interior walls and rooflines, particularly in attics. The effectiveness of either system depends on professional installation by spray foam professionals who understand the differences in material behavior, application thickness, and code compliance.
Open Cell vs Closed Cell Spray Foam Comparison
| Feature | Open Cell Spray Foam | Closed Cell Spray Foam |
|---|---|---|
| R-Value per Inch | ~3.5 | ~6.5 |
| Moisture Resistance | Low | High |
| Structural Strength | Minimal | Excellent |
| Application Areas | Interior walls, attics | Crawl spaces, basements, exteriors |
| Sound Control | High | Moderate |
| Expansion Rate | High (up to 100x) | Low (up to 40x) |
| Cost | Lower | Higher |
| Best For | Air sealing + interior comfort | Durability + moisture control |
Bonus Tip: In Bastrop’s mixed-humid climate, use closed-cell foam in any area subject to moisture exposure or external air leaks. It offers better water resistance and adds structural strength.
Technical Performance in Bastrop’s Climate
Installing insulation isn’t just about filling cavities—it’s about sealing the structure from unwanted heat, humidity, and airflow. That’s especially critical in Texas, where inefficient insulation can spike HVAC use and lead to condensation problems in hidden areas.
| Performance Metric | Standard Value (Closed Cell) | Reference Source |
|---|---|---|
| R-Value | R-6.5 per inch | U.S. DOE |
| Air Leakage Rate | <0.02 L/s·m² @ 75 Pa | ASTM E283 |
| Water Vapor Permeability | ≤1 perm at 1.5 inches | Building Science Corporation |
| Ideal Application Temp | Between 40°F to 120°F | Foam Manufacturers Association |
| HVAC Load Reduction | Up to 35% energy savings | Oak Ridge National Laboratory |
These values illustrate the importance of correct application. Improperly installed foam—whether underapplied or unevenly distributed—fails to deliver on the insulation’s promise. A reliable foam insulation contractor will always ensure spray foam is installed to spec and verified through testing.
Decision Factors Before You Insulate
Before installing spray foam, take time to assess a few critical factors. Not every building needs the same type of foam, and applying a one-size-fits-all solution can reduce energy performance over time.
Building type matters—barndominiums, metal shops, and pole barns lose heat and gain moisture differently than traditional homes. Use different insulation systems for different wall and roof assemblies. Crawl space design also plays a role; enclosed crawl spaces benefit from closed-cell foam due to its vapor resistance and rigid properties.
Budget is a consideration, but homeowners should weigh up-front insulation costs against the long-term energy savings. Foam insulation can lower monthly HVAC use by up to a third. This long-term reduction often pays back the cost of installation within 5–7 years.
Bonus Tip: Don’t overlook the attic. Attics are a major source of heat gain in Texas homes, especially when older batt insulation has degraded. A full attic retrofit with open-cell foam often delivers some of the best return on investment.

Common Questions to Ask Before Choosing Foam Insulation
How long will spray foam last in Bastrop homes? Spray foam insulation has a lifespan of 25–30 years or more if installed correctly. It doesn’t shift, sag, or deteriorate like batt or blown materials.
Is open-cell foam enough for exterior-facing walls? Not usually. Open-cell foam can absorb moisture, making it unsuitable for areas exposed to the outside. Closed-cell foam is more appropriate for those locations.
Can I combine spray foam with fiberglass? Yes. Many buildings use closed-cell foam for air sealing, followed by fiberglass for affordable thermal insulation in less vulnerable areas.
Will insulation help reduce humidity in the home? Yes. Spray foam blocks moisture-laden air from entering the home, which can reduce condensation and musty odors—especially in crawl spaces and attics.
Do I need a thermal barrier over foam? Yes, in areas where foam is left exposed. A thermal barrier like intumescent coating is required to meet fire safety standards.
Frequently Asked Questions
Can spray foam insulation be applied in older homes? Yes. Foam is commonly used in retrofit projects. Proper assessment is needed to confirm wall cavity conditions and ensure foam adhesion.
Will spray foam damage electrical wiring or plumbing? No. When installed by trained insulation specialists, foam doesn’t harm wires or pipes. It’s safe for use in most residential construction.
What happens if foam is applied too thick? Overapplication can cause improper curing or thermal expansion issues. That’s why it’s critical to use reliable foam experts with precise application control.
Does spray foam insulation attract pests? No. Foam doesn’t offer a food source or nesting material for rodents or insects, and it can help seal off entry points.
How can I check if the insulation is performing? A blower door test or infrared scan after installation can confirm air sealing performance and highlight weak points in insulation coverage.
