Trusted Radiant Barrier Installation for Converse Homeowners
Radiant barrier installation in Converse typically costs $1,800-$3,400 for a standard 2,000-square-foot attic, and most jobs are completed in a single day - see our full guide on how much Radiant Barrier Installation costs. We’re Topside Attic Insulation Converse, and we’ve been sealing and insulating homes under The Haven Standard since 2016. Our crews handle radiant barrier work in Converse neighborhoods from Woodlake to River Crossing, including same-day scheduling when attic temperatures are pushing equipment past safe operating limits. Call (830) 420-0953 for a written price before any work starts - that’s Haven Standard Clause 1, no exceptions.
Converse sits in Bexar County’s heat island, where attic temperatures regularly hit 140°F in July and August. That radiant heat doesn’t stay in the attic. It pushes through insulation, warms your ductwork, and forces your AC to run longer cycles. A properly installed radiant barrier - typically aluminum foil laminated to a substrate, or foil-faced sheathing applied to the roof deck - reflects up to 97% of that radiant energy back toward the roof deck. The result is a cooler attic, less thermal load on your insulation, and measurably lower cooling bills. We’ve installed Radiant Barrier Installation - Converse in over 9,000 homes since 2016, and we publish before-and-after blower-door numbers on every job where air sealing is part of the scope.
What Our Radiant Barrier Installation Service Includes
Attic Radiant Barrier
Attic radiant barrier is the most common application we see in Converse: reflective material installed across the attic floor, over existing insulation, or stapled to the underside of the rafters. You need this when your attic floor insulation is performing thermally but radiant heat from the roof deck is overwhelming it, a situation we see frequently in older Converse subdivisions like Converse Heights where roof decks are dark shingles with minimal overhang shading. Our crew measures attic temperature before and after installation with infrared thermometers, and we include those readings in your Documented Photo Record so you can verify the performance change.

Radiant Barrier Foil
Radiant barrier foil is the flexible, rolled product most homeowners picture - typically a reinforced aluminum foil with a scrim backing that resists tearing during installation. You need this when your attic has irregular joist spacing, numerous penetrations, or obstructions that make rigid panels impractical, which describes about half the attics we work in near FM 78 and Loop 1604. We source our foil from Owens Corning and Knauf, cut it to fit your specific joist bay dimensions rather than using generic widths, and overlap seams by a minimum of two inches to maintain the reflective surface’s continuity. Every roll lot is documented in your written scope.

Radiant Barrier Roof Deck
Radiant barrier roof deck application means attaching reflective sheathing or foil directly to the roof deck structure, either during new construction or retrofit. You need this when your attic is used for storage and you can’t sacrifice headspace to floor-mounted barrier, or when your existing insulation is being replaced and the roof deck is accessible - common in Converse’s newer builds from 2018-2023 near Radiant Barrier Installation - Schertz and Cibolo. We use foil-faced OSB or standalone radiant barrier attached with cap nails, and we always complete air sealing of top plates and penetrations first. Blowing insulation over an unsealed attic floor violates our Sealed First, Then Insulated protocol; we won’t do it.

Radiant Barrier & Ventilation
Radiant barrier and ventilation is a combined service we recommend for attics with limited natural airflow, which describes many homes in Converse’s established neighborhoods where mature oak canopy reduces roof surface wind exposure. You need this when your radiant barrier will perform better with convective heat removal - the barrier reflects radiant energy, but convective heat still builds if air isn’t moving. We assess your existing soffit and ridge venting, calculate net free area per the 1:300 rule, and install baffles or supplemental venting as needed. Your written scope specifies exactly what ventilation modifications are included, and we photograph before-and-after conditions for your record.

Brands We Service for Radiant Barrier Installation

We’ve worked extensively with Owens Corning radiant barrier products, including their LP TechShield radiant barrier sheathing and foil roll stock. Their sheathing integrates a perforated foil layer that allows moisture diffusion while blocking radiant heat, which matters in Converse’s mixed-humidity climate where vapor management can’t be an afterthought. We stock Owens Corning foil in 48-inch and 51-inch widths and can source their roof deck panels with 24-hour notice for new construction or full replacement jobs.
Our crews also install GreenFiber and Johns Manville radiant barrier systems regularly. GreenFiber’s stabilized cellulose with radiant barrier properties works well for homeowners who want combined insulation and reflective performance in a single application, particularly in attics with irregular joist spacing near Live Oak and Windcrest. Johns Manville’s foil-faced insulation boards provide a rigid option for roof deck retrofits where we’re removing existing insulation and starting fresh. Whether you have Owens Corning, GreenFiber, Johns Manville, or any other make, we can help. We carry no proprietary product lock-in, and our written scope specifies exactly what material and R-value you’re receiving.
Before
AfterSigns You Need Radiant Barrier Installation Right Now
- Your upstairs rooms are 8-12°F warmer than downstairs by mid-afternoon. This temperature stratification is a classic indicator that radiant heat from your roof deck is overwhelming your attic insulation’s conductive resistance. In Converse, where afternoon sun hits west-facing roof planes directly, we see this pattern most often in homes built between 2005 and 2015 with R-30 or less attic insulation and no radiant barrier.
- Your AC runs continuously from 2 PM to 8 PM but catches up overnight. This load profile means your cooling system is fighting accumulated thermal mass in the attic and ductwork, not just outside air temperature. A radiant barrier reduces the peak attic temperature that drives this late-day load, shortening run times and reducing compressor wear.
- Your ductwork in the attic feels hot to the touch in summer. Supply ducts in a 140°F attic are radiantly heated from all sides, even when they’re insulated. Reflective barrier on the roof deck or attic floor reduces the radiant temperature surrounding those ducts, improving delivered air temperature by 3-5°F in typical Converse installations we’ve measured.
- Your energy bills spike July through September despite consistent thermostat settings. If your usage pattern hasn’t changed but your kilowatt-hours jump 30-50% in peak summer months, radiant heat gain through the roof is a likely contributor. We can verify this with an attic temperature assessment during your free estimate.
- Your attic insulation appears compressed or discolored on the top surface. Compression from repeated radiant heating cycles degrades fiberglass and cellulose performance over time. Discoloration often indicates dust accumulation, which means air movement - and with it, convective heat transfer - is occurring through your insulation layer. Radiant barrier addresses the root cause by reducing the temperature differential driving that air movement.
Our Radiant Barrier Installation Process - Step by Step

- 1
Attic assessment and blower-door test. We start with a visual inspection of your attic floor, roof deck, and existing insulation, plus a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. In Converse homes, we typically see 3,500-5,500 CFM50 before any air sealing work. We photograph everything and record attic temperature at multiple points with an infrared thermometer.
- 2
Written scope and price delivered before work starts. Under Haven Standard Clause 1, you receive a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions. Your scope specifies material type, square footage, ventilation modifications if needed, and the blower-door target we’ll hit after air sealing. We also note any access limitations or safety concerns specific to your attic framing.
- 3
Air sealing of top plates, can lights, and penetrations. Sealed first, then insulated - in that order. We seal all accessible penetrations with fire-rated caulk, foam, or rigid blocking as appropriate. This step is mandatory before radiant barrier installation; we will not install barrier over an unsealed attic floor. The blower-door test is repeated after sealing to document improvement.
- 4
Radiant barrier installation per written scope. We install your specified material - foil to joists or rafters, rigid sheathing to roof deck, or combined insulation/barrier product - with proper overlap, fastening, and clearance around combustion vents and electrical fixtures. Every seam and penetration is photographed for your Documented Photo Record.
- 5
Final testing, documentation, and walkthrough. We conduct a final blower-door test where applicable, record post-installation attic temperatures, and compile your complete documentation: written scope, warranty, before-and-after blower-door readings, and timestamped photos. The 365-Day Done Right Promise applies from this date. If it’s not done right, we make it right.
How Much Does Radiant Barrier Installation Cost in Converse?
A typical attic radiant barrier installation in Converse runs $1,800-$3,400 for a 1,500-2,500 square foot home, depending on attic accessibility, existing insulation condition, and whether air sealing is needed. Radiant barrier roof deck application during a re-roof or full insulation replacement typically runs $2,800-$4,500 because of the additional labor to remove and replace existing materials. Combined radiant barrier and ventilation upgrades - adding soffit baffles, ridge vent extension, or powered venting - generally fall in the $3,200-$5,000 range for standard Converse home footprints.
Several factors move the price within these ranges. Steep roof pitches above 8:12 increase labor time and safety equipment requirements. Attics with limited access hatches or truss obstructions require more hand-cutting and custom fitting. Homes with active rodent issues need cleaning and proofing before barrier installation, which we handle through our attic cleaning and rodent proofing service. And if your existing insulation is compressed below its labeled R-value, removal and replacement may be more cost-effective than adding barrier over degraded material.

Frequently Asked Questions - Radiant Barrier Installation in Converse

Radiant barrier installation is the process of adding reflective material - typically aluminum foil on a substrate - to your attic floor, rafters, or roof deck to block radiant heat transfer from the roof surface into your living space. In Converse’s climate, this reduces attic temperatures by 20-35°F during peak summer conditions, which directly lowers the cooling load on your HVAC system and can reduce summer electric bills by 5-15% depending on your home’s construction and duct location.
Most residential radiant barrier installations in Converse are completed in 4-8 hours for a standard attic, or one full business day if air sealing and ventilation work are included. Larger homes above 3,000 square feet, steep roof pitches, or attics requiring insulation removal may extend to a second day. We specify the expected duration in your written scope before work starts, and we don’t leave until the job is complete and documented.
Attic radiant barrier installation in Converse typically costs $1,800-$3,400 for homes between 1,500 and 2,500 square feet, with roof deck applications running $2,800-$4,500 and combined barrier-plus-ventilation projects in the $3,200-$5,000 range. Your exact price depends on attic accessibility, existing condition, and whether air sealing or insulation replacement is needed. Call (830) 420-0953 for a free estimate with a written price before any work starts.
