Fast, Reliable Spray Foam Insulation Across Manor
Spray foam insulation in Manor typically runs $1,800-$4,500 for attic applications and $2,400-$6,200 for full roof-deck work, with most jobs completed in a single day. We’re Envelope Insulation Co., and our crews are in Manor regularly - from ShadowGlen to the Whisper Valley loop off Braker Lane - because the housing stock here has a specific problem that generic insulation contractors miss. Call (737) 259-7528 for a written price before any work starts; that’s Haven Standard Clause 1, no exceptions.
Why Topside Attic Insulation Round Rock Is Manor’s Preferred Spray Foam Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a disproportionate number of our blower-door records come from Manor’s fast-tracked subdivisions. The reason is straightforward: production builders here installed code-minimum R-38 blown fiberglass that settles and compresses within 5-7 years, and homeowners notice the failure first in their energy bills, not their attics.
Our reviews from Manor customers consistently cite two things - the before-and-after blower-door numbers we publish on every job, and the fact that we seal first, then insulate, in that order. One recent Whisper Valley homeowner put it this way: “They found air leaks I didn’t know existed, showed me the photos, and gave me a written scope before anyone touched the attic.” That’s standard for us. Dispatch and scheduling are coordinated from our Austin office, but our crews serve Manor locally and carry Icynene and Demilec materials stocked for this market.

Our Spray Foam Insulation Services in Manor
Closed-Cell Spray Foam
Closed-cell spray foam in Manor runs $2.80-$4.20 per board foot installed, and it’s what we specify for roof decks in ShadowGlen and Whisper Valley homes where attic cavity temps hit 155-160°F on Blackland Prairie summer days. The material cures to a rigid, moisture-resistant shell with an R-value of approximately R-6.5 per inch - roughly double the settled performance of the original blown fiberglass it replaces. In Whisper Valley specifically, closed-cell on the roof deck protects the Trane geothermal loop’s efficiency ratings by stopping the thermal bypass that forces longer heat-pump cycles. We air-seal all top plates, can lights, and penetrations before the foam goes in; blowing insulation over an unsealed attic floor violates our Haven Standard.
Open-Cell Spray Foam
Open-cell spray foam in Manor typically costs $1.60-$2.80 per board foot installed, and it’s our go-to for supplementing existing attic insulation that hasn’t fully failed yet. The material expands to fill irregular cavities - a useful trait in the low-pitched production roofs common east of 290 - and provides approximately R-3.6 per inch at full expansion. We used this approach in the Whisper Valley field call off Braker Lane: sealed the air pathways first, then sprayed Icynene open-cell over the compressed existing material to restore effective envelope value without a full tear-out. The homeowner’s Trane geothermal heat pump cycle times normalized within 48 hours. Every open-cell job gets a documented photo record and, where applicable, before-and-after blower-door readings.
Spray Foam Roof Deck
Spray foam applied directly to the roof deck in Manor costs $3,200-$6,200 for a typical 2,000-square-foot production home, and it’s increasingly necessary as original builder insulation cooks out in those 155-160°F attic peaks. This approach converts the attic from a vented, unconditioned space to a semi-conditioned envelope - the insulation lives where the thermal load is, not on the floor below it. For Whisper Valley homes tied to the shared EcoSmart geothermal loop, roof-deck foam is often the only way to maintain the envelope tightness the Trane system’s efficiency ratings depend on. We complete air sealing of all penetrations first, then foam; the written scope specifies brand, thickness, and target R-value before anyone lifts a tool.
Rim Joist Spray Foam
Rim joist spray foam in Manor runs $800-$1,800 for a typical post-2010 slab-on-grade home, and it’s the fix for cold floors and musty crawl-space odors that blown attic work never touches. The rim joist - the perimeter band where the foundation meets the first floor - is often unsealed in production builds, and on the Blackland Prairie it leaks both summer humidity and winter cold. We use closed-cell here for its moisture resistance, after sealing all penetrations. Every job gets a written price before work starts and a documented photo record when the crew leaves.
Garage Ceiling Spray Foam
Garage ceiling spray foam in Manor costs $1,200-$2,800 depending on whether the space above is conditioned living area or storage. With summer attic temps spiking past 150°F, an uninsulated garage ceiling radiates heat into bedrooms above - a common complaint in ShadowGlen’s two-story plans. We assess the floor assembly, seal penetrations for ductwork and wiring, then specify open-cell or closed-cell based on moisture exposure. Written scope, written price, written warranty. Always.

Trusted Brands We Service in Manor
We source spray foam materials from Icynene, Demilec, and CertainTeed - no proprietary product lock-in, so we specify based on what your assembly needs, not what our supplier is pushing. For Whisper Valley’s geothermal-tight envelopes, we often pair Icynene open-cell with Demilec closed-cell in hybrid assemblies where different cavity conditions demand different vapor profiles. Our Manor crews carry stock for same-day starts on most jobs, and we publish the brand and product name in every written scope so you know exactly what was installed.
Common Spray Foam Insulation Problems We See in Manor Homes
- Builder-blown fiberglass settled below R-30 in Whisper Valley and ShadowGlen attics. The original R-38 badge means nothing once compression and settling take hold - usually within 5-7 years in Manor’s heat. The Trane geothermal heat pump gets blamed for long cycles when the real culprit is an attic envelope that no longer performs.
- Low-pitched production roofs cooking out what little loft remains. Attic cavities in these designs reach 155-160°F when it’s 100°F+ on the Blackland Prairie. That heat degrades batt and blown insulation faster than in steeper pitches with better ventilation, making radiant barrier or closed-cell supplementation a near-necessity rather than an upsell.
- Underinsulated interior walls and attic hatches exposed by Winter Storm Uri. The February 2021 freeze revealed how little thermal protection post-2010 tract homes near historic downtown Manor actually had on their cold side. Spray foam in wall cavities and hatch perimeters fixes this; attic-floor blowing never will.
- Air leaks at top plates and can lights sealed after insulation, not before. We’ve pulled into Manor jobs where another contractor blew material over unsealed penetrations - the insulation performs like a sweater with holes in it. We seal first, then insulate. In that order. Every time.
Pricing for Spray Foam Insulation in Manor, TX
Most spray foam insulation jobs in Manor run between $1,800 and $6,200 depending on cavity type, accessibility, and whether we’re supplementing existing material or doing a full tear-out and replacement. Here’s how typical scopes break down:
| Application | Price Range (Manor) | Typical Board Feet |
|---|---|---|
| Open-cell attic supplement | $1,800-$3,200 | 800-1,500 |
| Closed-cell attic replacement | $2,800-$4,500 | 1,000-1,800 |
| Spray foam roof deck | $3,200-$6,200 | 1,200-2,500 |
| Rim joist (perimeter band) | $800-$1,800 | 300-600 |
| Garage ceiling | $1,200-$2,800 | 500-1,000 |
What moves the number: roof pitch and accessibility (low-pitched Manor production roofs are harder to work in), whether we need to remove settled existing material first, and whether the job requires hybrid open-cell/closed-cell assemblies for moisture management.

FAQs - Spray Foam Insulation in Manor
It’s almost always an insulation problem first. We’ve diagnosed this exact scenario dozens of times in Whisper Valley: the Trane geothermal heat pump is engineered to a specific envelope tightness, and when builder-blown attic insulation settles below R-30 effective value, the system runs longer cycles to compensate. The heat pump isn’t failing; it’s working harder than it should because the attic is leaking conditioned air. We verify with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - and we publish before-and-after numbers on every job. Call (737) 259-7528 for an exact quote; estimates are free.
Whisper Valley is tied to a shared EcoSmart geothermal loop system by Trane, and every home’s energy-performance guarantee depends on maintaining a specific envelope tightness. A leaky or undersized attic package directly undermines those efficiency ratings and can void builder guarantees. In Pflugerville or standard Austin subdivisions, spray foam is a comfort upgrade; in Whisper Valley, it’s an envelope requirement with technical stakes that don’t exist elsewhere. Our written scopes for Whisper Valley specify target air-leakage rates and blower-door verification for this reason.
Sometimes, but only after we test what’s actually there. The R-38 badge on original ShadowGlen installs rarely reflects current performance; compression and heat degradation typically drop effective value to R-25 or below within 5-7 years. If the material is merely settled and not mold-compromised, we can air-seal all top plates and penetrations, then supplement with open-cell spray foam to restore effective envelope value. If it’s compressed, displaced, or moisture-damaged, we remove it first. The written scope specifies which approach before anyone lifts a tool. Call (737) 259-7528 for an assessment.
The temperatures are real, and the degradation is documented. On the Blackland Prairie, low-pitched production roofs common in ShadowGlen and Whisper Valley create attic cavities that reach 155-160°F when ambient temps exceed 100°F. Fiberglass batt and blown cellulose lose loft - the trapped air that provides insulation value - under sustained thermal load. We’ve pulled material from Manor attics that measured half its original thickness. Closed-cell spray foam doesn’t compress or settle under these conditions, which is why we specify it for roof-deck applications here. The before-and-after blower-door numbers on our jobs prove the performance change.
February 2021 exposed how little thermal protection these homes had on their cold side. The post-2010 production builds near historic downtown Manor - and throughout ShadowGlen - showed rapid heat loss through underinsulated interior walls, unsealed attic hatches, and rim joists that code-minimum attic-floor blowing never addressed. Homeowners who’d never had comfort complaints suddenly had frozen pipes and 48-hour indoor temperature crashes. Spray foam in wall cavities, rim joists, and hatch perimeters fixes the thermal bypasses that Winter Storm Uri made visible. We document every penetration we seal with photos you keep. Call (737) 259-7528 to schedule an assessment.
