GreenFiber Radiant Barrier Installation: The Converse Owner’s Guide
We stock and install GreenFiber-compatible radiant barrier systems in Converse, TX, with most attic installations running between $1,800 and $3,400 depending on roof pitch and square footage. Same-day installation is available when you call before noon, and we carry GreenFiber-certified rolls and staples on every truck. Most Converse homeowners discover their radiant barrier is failing when the upstairs bedrooms won’t cool below 78°F even with the AC running continuously, or when they spot sagging, torn foil hanging from the rafters during a holiday decoration trip to the attic.
Which GreenFiber Models This Applies To
GreenFiber doesn’t sell radiant barrier as a standalone branded product line. Instead, they manufacture low-dust cellulose insulation, blown in loose-fill form, that’s frequently paired with aftermarket radiant barrier foil in mixed insulation systems. If your attic has GreenFiber cellulose on the floor and radiant barrier stapled to the rafters above it, you’re in the right place. We see this combination in roughly 60% of the Converse homes we audit, especially the 1,400-2,200 square foot builds from 1995-2010 near Foster Road and Loop 1604.
To identify what you have: check the attic floor for grayish, fibrous loose-fill with a fire-retardant odor (that’s the GreenFiber cellulose). The radiant barrier above it is typically perforated aluminum foil, either double-sided (foil-foil) or foil-kraft, in rolls of 4 or 5 foot width. We stock both OEM-grade AtticFoil and quality aftermarket equivalents that match GreenFiber’s R-value targets without the proprietary markup. The compatibility gotcha: GreenFiber cellulose compresses to R-3.7 per inch, so if your existing radiant barrier was sized for fiberglass batt clearance, the foil may be too close to the deck and trapping moisture. We measure that clearance before quoting.

Signs Your GreenFiber Radiant Barrier Installation Is Failing
- Upstairs rooms stay hot past 9 PM. In Converse, attic temperatures peak around 4 PM but should drop after sunset. If your radiant barrier has torn away from the ridge or developed gaps at the eaves, infrared radiation is penetrating the foil and heating your ductwork. We see this most in homes where staples were spaced wider than 24 inches.
- Foil is sagging, torn, or lying on the insulation below. GreenFiber cellulose is heavier than fiberglass; over years, vibration from the AC unit can cause poorly secured foil to detach and fall. Once it’s contacting the insulation, it’s no longer a radiant barrier, it’s a conductor.
- Water stains on the foil surface. Converse’s spring storms drive humidity through ridge vent gaps. If your radiant barrier isn’t perforated, or if the perforations are clogged with dust, moisture condenses on the foil and drips onto the GreenFiber below. That cellulose soaks it up, compacts, and loses R-value permanently.
- Energy bills jumped 20% or more from the same month last year. A failing radiant barrier doesn’t fail gradually in our experience. One torn seam at the south-facing slope can raise attic temperature by 15-25°F, and your AC compensates immediately. We pull CPS Energy bill histories during audits to confirm the timing.
- You see daylight through the foil at the peak. This means the barrier was never properly sealed at the ridge, or the tape has failed. In Converse’s climate, that’s an open path for 140°F attic air to radiate straight into your living space.
Before
AfterReplacement Cost & What’s Included
| Component | Price Range (Converse) |
|---|---|
| Perforated radiant barrier foil (OEM-grade, 1,500-2,500 sq ft attic) | $0.45-$0.72 / sq ft material |
| Labor: removal of failed foil, re-staple to rafters at 12″ spacing | $1,100-$1,800 |
| Air sealing of top plates and penetrations (prerequisite) | $380-$650 |
| Blower-door test: before and after | Included |
| Documented Photo Record | Included |
| Typical total installed | $1,800-$3,400 |
What drives the range: roof pitch over 8/12 adds labor hours, attic square footage above 2,500 requires additional material, and homes with active rodent damage need cleaning before we install. We don’t blow new GreenFiber over failed radiant barrier, and we don’t staple new foil over unsealed air leaks. Every job starts with a written price, flat and complete, before anyone enters the attic. Under our 365-Day Done Right Promise, if the foil sags or the blower-door numbers don’t hold, we return and correct it.
DIY or Call Us?
Here’s what you can safely check yourself: confirm the foil is still attached to rafters (don’t touch it, just look from the attic hatch with a flashlight), note any water staining, and take a photo of the staple pattern if you can. What you shouldn’t do: walk a GreenFiber-covered attic floor without proper decking, pull down foil to inspect behind it, or attempt to staple new material while balancing on joists. The cellulose conceals electrical wiring and can hide weak ceiling drywall.
The real risk isn’t the radiant barrier itself, it’s what DIY installation skips. We’ve audited Converse attics where homeowners installed beautiful new foil but left top-plate gaps leaking 400 CFM50 of conditioned air. The foil looked correct; the house still bled money. We run a blower-door test before and after every job so you leave with printed proof the envelope tightened. Call (830) 420-0953 for a free estimate with a written price before any work starts.
FAQs
In Converse’s climate, properly installed perforated radiant barrier foil lasts 15-25 years. The failure point is almost never the foil material itself, it’s the attachment method: staples corrode, tape dries out, and vibration from nearby AC compressors works fasteners loose. We use stainless staples at 12-inch intervals and foil tape at all seams, which typically outlasts the original installation by a decade. Call (830) 420-0953 for an exact quote on your attic, estimates are free.
Patching is possible for isolated tears smaller than a dinner plate, but we rarely recommend it. The original staple pattern has already failed, and patching leaves seams that trap dust and reduce reflectivity. In Converse’s dusty hill-country environment, we’ve found full replacement with proper air sealing costs only 30-40% more than patchwork and delivers measurable results on the blower-door test. Call (830) 420-0953 for an exact quote, estimates are free.
Most GreenFiber radiant barrier replacements in Converse are completed in one working day, typically 4-6 hours for attics under 2,500 square feet. We arrive, run the pre-work blower-door test, remove failed foil, seal top plates and penetrations, install new barrier, and run the post-test before we leave. You’ll have printed documentation the same evening. Call (830) 420-0953 to schedule, same-day availability when you call before noon.
We stock perforated aluminum radiant barrier foil in 4-foot and 5-foot rolls, stainless staples, and foil tape on every Converse service vehicle. We don’t stock GreenFiber cellulose itself on trucks, we order it to spec after measuring your attic depth and target R-value. For radiant barrier-only calls, we can typically install same-day. Call (830) 420-0953 to confirm current truck stock for your attic size.
Seal the leaks first. Then insulate. The numbers will tell you if it worked.
