Rockwool Home Energy Audit in New Braunfels: What to Know First
We provide independent Rockwool home energy audit in New Braunfels, typically scheduling within 48 hours and completing most audits same-day. Every audit starts with a written price before any work begins, and you’ll walk away with printed blower-door numbers, thermal images, and a documented photo record of what we found. We are not affiliated with or authorized by Rockwool; we are an independent Rockwool service provider that treats air sealing as a hard prerequisite, not an upsell.
This page is for Rockwool owners in New Braunfels who want to know why their energy bills keep climbing despite good insulation, or who need documentation before selling a home off the River Road corridor or in one of the newer developments near Fischer. Call (830) 243-6352 for a free estimate, or text us if that’s easier.
How Rockwool Products Fail - and How We Fix Them
- Comfortbatt thermal bridging at stud bays. Comfortbatt’s semi-rigid batts can leave gaps at the edges of standard 16-inch on-center framing, especially in the older slab homes common near downtown New Braunfels where wall framing isn’t always plumb. We find these gaps with thermal imaging, then seal with Rockwool-specific compression fitting or, where the gap is too wide, recommend a flash-and-batt hybrid with closed-cell foam to eliminate the bridge.
- Comfortboard 80 moisture retention in crawl spaces. Comfortboard 80 is rated for exterior use, but we’ve seen it installed on interior crawl space walls in New Braunfels homes where seasonal humidity above 70% saturates the outer layer. The board doesn’t mold, but it stops insulating effectively. We pull moisture readings with a pinless meter, replace compromised sections, and pair the repair with proper vapor barrier installation so the new material stays dry.
- Afb evo sag in attic floor applications. Afb evo acoustic batts are sometimes used for attic floor insulation by homeowners who bought the wrong product for the application. The lower density lets it settle over time, creating a 10-15% loss in R-value within five years. We document the sag with depth measurements and photos, then recommend either reinstallation with proper supports or replacement with a denser Rockwool attic product.
- TopRock DD compression from foot traffic. TopRock DD is designed for flat roof decks, but in New Braunfels we’ve found it crushed by HVAC techs and solar installers walking the roof. Compressed mineral wool loses up to 40% of its thermal resistance. We map the damaged areas during our thermal walk, quote replacement in kind, and install walk boards for future access.
- Rockwool cavity fill incomplete around obstructions. Whether it’s Comfortbatt or Afb, installers often miss the narrow gaps around electrical boxes, plumbing vents, and top plates. These bypasses don’t show on a visual inspection, but they show clearly on a blower-door test. We seal every penetration with fire-rated caulk or foam before any Rockwool goes back in, because insulation over an unsealed air leak is just an expensive filter.
Our Rockwool Home Energy Audit Process
- 1
Written price before we start. You get a flat price, written scope, and written warranty before anyone touches your attic. That’s Haven Standard Clause 1.
- 2
Blower-door baseline. We run a pressurization test to measure CFM50, the cubic feet of conditioned air your home leaks per minute at 50 pascals of pressure. In New Braunfels, we typically see 3,500-5,500 CFM50 in pre-2010 homes, and we file this number by your address.
- 3
Thermal imaging and insulation inspection. We walk the attic, walls, and crawl space with a FLIR camera, mapping Rockwool gaps, compression, moisture intrusion, and thermal bridging. We also inspect ductwork for leakage, since duct losses can mimic insulation failure.
- 4
Duct leakage test if indicated. When the blower-door numbers don’t match the insulation condition, we run a duct blaster to isolate whether your conditioned air is escaping into the attic before it reaches the rooms.
- 5
Written findings with photos and prioritized scope. You get a Documented Photo Record on every visit, plus a ranked list of what to fix first, what can wait, and what the post-work blower-door target should be.
- 6
Post-work verification. On any job we perform, we run the blower door again and publish the before-and-after numbers so you can verify the improvement. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
Before
AfterWhat Rockwool Home Energy Audit Costs in New Braunfels
Most Rockwool home energy audits in New Braunfels run between $350 and $750 for a single-family home under 3,500 square feet. What moves the price:
- Basic audit (blower door + thermal imaging): $350-$450. Covers attic, main living areas, and a written report with photos.
- Standard audit (adds duct blaster and crawl space): $500-$650. For homes with HVAC in the attic or suspected crawl space issues.
- Comprehensive audit (whole envelope, multiple zones, extended documentation): $650-$750. Common for pre-2000 homes off River Road or for sellers needing inspection-ready documentation.
Homes over 3,500 square feet, multi-story layouts, or those with spray foam existing insulation may run higher. We also provide a Free Second Opinion on any written estimate you’ve already received, we’ll read it with you and tell you where the scope differs from ours.

FAQs
No. As an independent Rockwool service provider, our audit is non-destructive and does not affect any existing product warranty. We document condition without altering installation, and if we do perform work, we use Rockwool-compatible methods that preserve warranty coverage where applicable. Call (830) 243-6352 if you need documentation for a warranty claim.
We typically schedule within 48 hours, and same-day availability happens often. A live person answers calls 24/7, so you’re not waiting for a callback window. Call (830) 243-6352 or text to check today’s openings, estimates are free.
Repair is usually cheaper if the Rockwool is dry, uncompressed, and properly installed but missing at penetrations or edges. Replacement makes sense when we find moisture saturation, significant compression, or wrong-product-for-application issues like Afb evo in an attic floor. We quote both paths when both are viable. Call (830) 243-6352 for a written price on either option.
We stock common Rockwool products and have supplier relationships in San Antonio for same-day or next-day access to specialized lines. If your audit reveals a need for replacement, we tell you exactly what’s in stock, what needs ordering, and how long before we can complete the work. No open-ended timelines.
You keep the printed blower-door report with pre-work CFM50 reading, thermal images on USB or email, the written scope with prioritized recommendations, and the Documented Photo Record from our walkthrough. If we perform work, you also get the post-work blower-door numbers showing the measured improvement. Wes keeps a filed copy by address, which has helped past New Braunfels homeowners when a buyer’s inspector asked questions during sale.
