Living in Central Texas means battling intense heat and humidity, which can easily penetrate standard fiberglass batting. To truly secure your indoor environment, it is essential to establish a continuous thermal envelope that prevents air leakage and moisture infiltration. Our advanced application techniques create a monolithic seal, effectively closing the gaps left by traditional insulation. This not only stabilizes indoor temperatures but also improves indoor air quality by blocking allergens and dust from entering your living space.

Challenge: A homeowner in the Forest Creek neighborhood reported that their upstairs bedrooms were consistently 10 degrees hotter than the ground floor, forcing their AC to run non-stop.
Solution: We performed a full extraction of the settled fiberglass and applied 5.5 inches of Open-Cell Spray Foam to the underside of the roof deck.
Result: The attic temperature dropped by over 30 degrees within 24 hours. The homeowner reported an immediate balance in temperature between floors and a significant reduction in HVAC runtime.

Open-cell foam is lighter, expands rapidly to fill voids, and is excellent for soundproofing and interior thermal insulation. Closed-cell foam is much denser, acts as a vapor barrier, resists water, and adds structural strength, making it ideal for exterior walls or areas prone to moisture.
Yes, spray foam is highly effective at sound dampening. Open-cell foam, in particular, absorbs sound waves, significantly reducing noise transmission from outside traffic or between rooms within the house, creating a quieter living environment.
Installing high-performance insulation is a desirable upgrade for homebuyers. It signals lower future utility costs, better structural health, and a modernized HVAC environment, which can increase market appeal and boost the property's resale value.
While it depends on the specific situation, removal is generally recommended. Removing old, dusty, or pest-damaged fiberglass allows the foam to bond directly to the substrate (the wood frame), ensuring a perfect air seal and allowing for a thorough inspection of the attic for any electrical or structural issues.
Most residential projects in Round Rock, such as an attic retrofit or a crawl space encapsulation, can be completed in one to two days. Larger commercial projects or whole-home new construction jobs may take longer, but we always strive to minimize disruption to your schedule.
