Rockwool Crawl Space Encapsulation & Vapor Barrier Nationwide

Rockwool Crawl Space Encapsulation & Vapor Barrier in Schertz: What to Know First

We provide independent Rockwool crawl space encapsulation and vapor barrier service in Schertz, typically completing most jobs in one to two days depending on crawl space size and moisture severity. Our written price comes before any work starts, and we publish before-and-after blower-door numbers on every applicable job so you can verify the air-sealing result yourself. This page is for Rockwool owners in Schertz who’ve noticed musty odors, sagging insulation, or humidity readings above 60% in their crawl space and want a technician who understands how Rockwool’s stone wool products interact with Texas Hill Country moisture patterns.

How Rockwool Products Fail - and How We Fix Them

• Comfortbatt R-15 settling in band joists. The semi-rigid batts lose their friction fit when seasonal humidity swings in Schertz, typically March through May, cause the wood to expand and contract. We find these batts collapsed onto the vapor barrier or fallen entirely. Our fix: re-secure with mechanical fasteners plus targeted air sealing at the rim joist before reinstalling, because the batt can’t do its job if air is washing around it.
• Comfortboard 80 wicking ground moisture. This rigid board is sometimes used for crawl space perimeter walls, and in Schertz’s clay-heavy soils, capillary rise can wick moisture into the bottom edge even with a vapor barrier present. The board doesn’t rot, but it becomes a thermal bridge when saturated. We cut and install a capillary break of closed-cell spray foam at the base, then replace any moisture-compromised sections.
• AFB evo batts retaining odor after plumbing leaks. The formaldehyde-free binder in AFB evo is marketed as mold-resistant, which it is, but we’ve pulled these batts from Schertz crawl spaces where a slow drain leak introduced organic material the binder couldn’t repel. The batt structure stays intact, but the smell lingers. We remove, document with photos, treat the joist bays with antimicrobial, and reinstall only after the source is fixed and verified dry.
• Rockwool loose-fill in inaccessible corners creating gaps. Blown-in stone wool settles differently than fiberglass, and in the tight corners of older Schertz homes near the original downtown grid, we find voids where the fill never reached or settled away from the subfloor. We dense-pack those corners with damp-spray cellulose or remove and replace with batts cut to fit, depending on access.
• Vapor barrier displacement from Rockwool’s weight. Stone wool is heavier than fiberglass per R-value, and when batts sag or fall, they can drag or puncture 6-mil polyethylene barriers. In the Sedona subdivision and similar Schertz builds, we’ve replaced barriers torn by fallen Comfortbatt with reinforced 12-mil woven polyethylene, properly seam-sealed and mechanically anchored to walls.

Our Rockwool Crawl Space Encapsulation & Vapor Barrier Process

1. 1
   Inspection and moisture mapping. We enter with a thermal imaging camera, pinless moisture meter, and humidity logger. We document existing Rockwool product type, condition, and location with photos you’ll receive in your record.
2. 2
   Blower-door test if the crawl space is conditioned or semi-conditioned. This pressurization reading shows, in one number, how much air your building envelope is losing through the crawl space. We establish the baseline before touching anything.
3. 3
   Air sealing before any insulation work. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it, and the same law applies to your crawl space. We seal rim joists, sill plates, penetrations, and any duct boots with appropriate sealants.
4. 4
   Material selection: OEM Rockwool vs. alternatives. We match replacement Rockwool products by application, or specify Reflectix or other materials where the job calls for it. As an independent Rockwool service provider, we have no proprietary lock-in.
5. 5
   Encapsulation or vapor barrier installation. Woven polyethylene barriers, sealed seams, wall extensions per condition. Insulation reinstalled or upgraded. Dehumidifier sizing if needed.
6. 6
   Post-work verification and documentation. Repeat blower-door test where applicable, photo record of all work areas, written scope completion signed by the crew lead. You get the folder before we leave.

These are the ranges we typically see on written estimates in Schertz, including the Sedona area and homes off FM 1518.
