With over a decade of expertise in the spray foam industry, we’ve encountered a wide range of scenarios—from the highly successful to the more challenging. This experience has enriched our understanding of what truly works best in various projects and what pitfalls to avoid. To share this wealth of knowledge, we’re excited to announce that we’ll be posting weekly articles right here. These posts will cover a variety of topics including answers to some of the most frequently asked questions, professional tips, and insights into the obstacles we’ve overcome. Join us as we delve into the fascinating world of spray foam insulation, providing you with valuable information to help ensure your projects thrive.
What is R-value?
R-value measures an insulating material’s resistance to conductive heat flow, as described by the U.S Department of Energy. If a material has a higher R-value, it has a higher level of insulating effectiveness.
There are several standards of R-value, and what is best for you depends on the structure and climate zone of your area. One of our skilled technicians can help you evaluate which R-value is best for your spray foam insulation project. At Lone Star Urethane, we are able to meet any R-value you need.
Can I add new spray foam insulation on top of old insulation?
No, it is not recommended to add new insulation on top of the old insulation. The previous foam insulation needs to meet certain criteria and it will also depend on the wear and tear of the old insulation. You can call us at Lone Star Urethane for an insulation evaluation.
Can insulation help reduce unwanted sound?
Yes! There are many foam insulation methods to help reduce unwanted sound throughout your home or business.
What should I do to prepare for my service?
We recommend a quick in-home inspection before your service begins. Residences or businesses must be empty at the time of your service, and we encourage folks to be prepared to vacate their house or business for 24 hours after the application.
How do I know if my attic is under-insulated?
To properly assess your attic insulation, we strongly suggest a free evaluation from one of our foam insulation technicians at Lone Star Urethane.
How much is spray foam insulation?
Each project is unique! There are different matters of construction and installation objectives that can impact the cost of your project. Environment and structure can also play a key role in determining the price. We are happy to review your structure and offer a fair and competitive solution for your spray foam insulation needs. Contact Lone Star Urethane for a free estimate.
Why Is Spray Foam Insulation Superior?
Spray foam insulation is considered superior due to its higher R-value, longevity (can last 80 years or more), and its ability to protect homes from moisture and fire damage. It doesn’t lose its R-value over time and is excellent for energy efficiency.
What is the difference between open-cell and closed-cell foam?
Closed-cell spray foam and open-cell spray foam are both types of polyurethane-based insulation, but they have distinct differences primarily due to their cell structure and density. Closed-cell foam has a denser and more compact structure, with each cell fully enclosed and not interconnected. This composition gives closed-cell foam a higher R-value per inch (around 6-7 per inch), meaning it provides superior insulation and is more effective in preventing air and moisture infiltration. Consequently, closed-cell foam is also more rigid and adds structural strength to the areas where it’s applied. It serves as an excellent vapor barrier, making it suitable for use in environments where moisture control is critical. On the other hand, open-cell foam has a softer, more flexible structure with cells that are not completely enclosed, allowing air to fill the open space inside the material. This results in a lower R-value per inch (about 3.5 per inch) compared to closed-cell foam. However, open-cell foam is excellent for soundproofing due to its ability to absorb sound and vibrations. It’s also more permeable to moisture, which can be beneficial for allowing a building to breathe, although it’s not recommended in spaces where a vapor barrier is necessary. Open-cell foam is generally less expensive than closed-cell foam and can be a cost-effective solution for interior walls where insulation and sound dampening are priorities.
How do I know I’m getting a quality product?
When it comes to insulation, the quality of the product is paramount, and it’s true that not all manufacturers are created equal. Some stand out by offering exceptional long-term support and pioneering the development of state-of-the-art insulation solutions. Others may focus on delivering a product that’s more budget-friendly without compromising on quality. Your installer plays a crucial role in this process. A reputable installer will transparently provide you with an insulation certificate directly from the manufacturer, clearly detailing the specific product used in your project. This certificate is your assurance of quality and accountability. We strongly advise partnering with installers who are forthcoming with this information and steer clear of those who are not able to furnish detailed product specifics before the installation commences. Your peace of mind is worth it, and choosing the right installer is the first step towards a well-insulated, comfortable space.
When Should I Install Spray Foam Insulation?
It’s best to install spray foam insulation during the building phase of a new home, ideally after the installation of basic plumbing, electrical wiring, and HVAC ducts but before the drywall is installed. However, it can also be applied to crawl spaces, attics, or roofs of existing homes.
Which is Better: Open- or Closed-Cell Foam?
The choice between open- or closed-cell foam depends on the project and location. Closed-cell foam is better at repelling moisture, while open-cell foam can be installed in a wider variety of locations. The specific insulation requirements of the project will determine the best choice.

Can Installing Spray Foam Insulation Save Me Money?
Yes, spray foam insulation can lead to energy savings by preventing air leakage and improving heat resistance, thereby reducing reliance on heating and cooling systems and lowering energy bills.
How Does Spray Foam Affect Resale Value?
Spray foam insulation can add considerable value to a home, making it a desirable feature for potential buyers. Its long lifespan ensures that it remains a valuable addition to the home even when it comes time to sell.
Is Spray Foam Insulation a Fire-Resistant Material?
While not completely fireproof, spray foam insulation has some fire-resistant properties. It can help slow down the spread of flames and smoke, providing added protection in case of a fire.
