Spray Foam Type Guide
Minimal ExpandingAround windows/doors — won't bow the frame
Standard ExpandingGeneral gap and crack filling — most common
Max FillLarge voids, block cores — aggressive fill
Fire-RatedRequired at all penetrations in fire-rated assemblies

Insulation & Tools FAQ

What R-value do I need for walls in Houston?
Houston is in IECC Climate Zone 2A. For wood-framed walls, the energy code minimum is R-13 in a 2×4 wall or R-20 in a 2×6 wall. In practice, most residential new construction here uses R-13 or R-15 in a 2×4 wall and R-19 in a 2×6 wall. For steel-framed walls, you often need to compensate for thermal bridging through the studs — a layer of continuous rigid foam on the exterior adds R-5 to R-10 and dramatically improves the effective R-value of the assembly. Call us and we'll help you spec the right combination.
Faced or unfaced insulation — what's the difference?
Faced insulation has a kraft paper or foil vapor retarder on one side — it's used when you want a vapor control layer and the facing goes toward the warm side of the assembly (in Houston, that's the interior in summer). Unfaced insulation has no facing and is used when you're layering over existing insulation in an attic, in interior partition walls where no vapor retarder is needed, or when a separate vapor barrier is being installed. In most Houston climate applications, unfaced is common in attics because you're typically building up depth over existing insulation. If you're unsure, call us — getting this wrong can cause moisture problems.
Do I need acoustic insulation in addition to resilient channel?
For most residential sound isolation (party walls in multi-family, home theaters), acoustic insulation plus resilient channel plus double-layer drywall is the standard stack. The acoustic batt absorbs sound energy within the cavity, the resilient channel decouples the drywall from the framing, and the mass from two layers of drywall blocks transmission. Any one of these alone gives modest improvement — the combination is where you hit STC 55+. If your spec just says "improve STC from 35 to 50," acoustic insulation plus a single RC-1 layer and one extra drywall layer typically gets you there. Call us with your target STC and we'll help you design the assembly.
What spray foam should I use around window rough openings?
Always use minimal-expanding foam (sometimes called "window and door" foam) around rough openings. Standard or max-fill expanding foam generates significant pressure as it cures — enough to bow a window or door frame and prevent it from opening and closing correctly. Minimal-expanding foam fills the gap for air sealing without creating that pressure. Spray it in two thin passes rather than one thick fill. Around rough framing (not the window unit itself), standard expanding foam is fine.
Do you stock drywall stilts and can anyone buy them?
Yes — we carry aluminum drywall stilts and drywall panel lifts for purchase. These are contractor tools, not rental equipment, and anyone can buy them. Stilts typically run 18"–30" adjustable rise and are used by drywall tapers and painters to work at ceiling height without constantly repositioning a ladder. Panel lifts hold ceiling drywall sheets at height while you fasten them — essential for one- or two-person ceiling work. Call us to confirm current inventory before making the trip.
