Imagine stepping into your home on a scorching summer day and feeling a refreshing, even coolness throughout every room. In Liberty Hill and the surrounding Central Texas areas, closed cell spray foam insulation offers more than just comfort—it provides powerful energy efficiency, reduces moisture intrusion, and helps keep allergens at bay. Thanks to its dense, air-sealing properties, closed cell insulation is ideal for tackling the region’s challenging climate. With years of experience and a commitment to precision, Spray Foam Tech installs high-quality insulation solutions that enhance your home’s performance, durability, and indoor comfort.
Closed cell spray foam insulation does more than seal gaps—it reinforces the structure of your walls and roofs while dramatically improving energy efficiency. Its dense composition forms an air and vapor barrier, reducing air leakage and protecting against moisture buildup.
For Liberty Hill homes and businesses, this means better indoor air quality, reduced strain on HVAC systems, and fewer pest problems. The high R-value per inch—typically around 6.5 to 7—outperforms other insulation types and gives long-term returns through lower utility costs.
Proper installation matters just as much as product quality. Closed cell foam must be applied with care to ensure consistent thickness, adhesion, and coverage across all surfaces. The process involves assessing each structure individually and spraying the foam in layers to reach the desired R-value without overapplication.
Spray Foam Tech has been installing insulation in the Liberty Hill area since 2007, always considering the full picture. If another solution suits your space better, you’ll hear that upfront. Every job starts with a conversation, not a sales pitch.
Both closed cell and open-cell spray foam insulation have unique benefits tailored to specific applications. Closed cell insulation is especially valued for its high structural strength and excellent moisture resistance, making it ideal for exterior walls, basements, and crawl spaces. One of its standout features is the closed cell foam insulation R-value, which is significantly higher than that of open-cell types.
In fact, the closed cell insulation R-value per inch typically ranges between R-6 and R-7, offering superior thermal resistance. This makes it one of the best closed cell foam insulation options for homeowners seeking energy efficiency and long-term performance. On the other hand, open-cell spray foam is better suited for interior projects where breathability and sound absorption are key priorities
Feature | Closed Cell Foam | Open-Cell Foam |
Thermal Performance (R-value) | Higher R-value per inch | Requires more thickness to match R-value |
Moisture Handling | Resists water; acts as vapor barrier | Allows moisture to pass; promotes drying |
Flexibility and Expansion | Rigid and compact | Expands more to fill irregular spaces |
Structural Contribution | Adds strength to walls and roofs | Lightweight; won’t stress framing |
Sound Absorption | Moderate | Excellent |
Ideal Uses | Crawl spaces, basements, exterior walls | Attics, interior walls, soundproofing |
Things to consider: The best choice depends on your building’s layout, insulation goals, and environmental exposure. Many Liberty Hill homes benefit from a mix of both types in different parts of the structure.
Thickness depends on location within the structure and your energy efficiency goals. For walls, 2 inches often delivers the desired R-value. Roof decks or ceilings may require 3 inches or more to meet building codes and maximize thermal performance.
Spray Foam Tech works with each client to determine what’s right for their property. Over-insulating adds cost without benefit, and under-insulating won’t get results. Careful measurement, planning, and execution ensure that each layer does what it’s supposed to.
The cost of closed cell spray foam insulation varies based on square footage, application complexity, and target R-value. On average, Liberty Hill homeowners can expect pricing between $1.00 and $1.50 per board foot. While more expensive upfront than fiberglass or open-cell options, it pays off through durability and monthly savings.
Industry fact: Closed cell foam can last over 30 years without degrading, outperforming most traditional insulation products. When you factor in lower maintenance and energy use, it’s a smart investment—not just an expense.
Homes and businesses in Liberty Hill face temperature swings, high humidity, and powerful storms. Closed cell foam insulation is especially effective in this region because it adds strength to buildings, resists mold, and keeps conditioned air inside.
Whether you're building new or improving an older structure, insulation must keep up with Texas heat and weather extremes. Spray Foam Tech understands the specific needs of Liberty Hill properties and helps customers choose the option that performs best where it matters most.

Typically 2 inches for walls and 3 inches for ceilings or roofs, but it varies by building code and performance goals.
Closed-cell spray foam usually has an R-value of about 6.5 to 7.0 per inch.
For moisture control, structural reinforcement, and insulation in extreme weather, closed-cell is often the better option.
It can last more than 30 years without losing effectiveness.
Square footage, application thickness, and structure design all impact final pricing.
