Residential Spray Foam
Attic Insulation That Actually Stops Desert Heat
A Las Vegas attic can hit 150 degrees F in summer. Spray foam seals the roofline and framing into one continuous air barrier, so that heat stays out of your living space instead of soaking through the ceiling.

Overview
Why Attics Are Ground Zero for Vegas Energy Bills
In the Las Vegas valley, an under-insulated attic is usually the single biggest reason an air conditioner runs nonstop from May through September. Batt insulation compresses, settles, and leaves gaps around trusses, wiring, and recessed lights.
We spray a continuous layer of medium-density foam directly to the underside of the roof deck or across the attic floor, depending on your homes design.
- Seals rooflines, top plates, chases, and can-light housings in one pass
- Reduces attic temperature swings, easing strain on your HVAC system
- Keeps its R-value permanently, no settling or sagging over time
- Can be installed in new construction or retrofitted into existing attics
What's Included
What's Included In Every Attic Project
Every attic is scoped individually, but most projects include the same core scope of work.
Air-Seal & Inspect
We inspect existing insulation, ventilation, and any moisture issues before spraying.
Open-Cell or Closed-Cell
We recommend the right foam type and thickness for your roof assembly and budget.
Ignition & Vapor Barrier
Where code requires it, we apply an intumescent thermal barrier coating over exposed foam.
Vent Baffle Installation
Baffles are installed at the eaves first when venting is retained.
Attic Access Sealing
Pull-down stairs and scuttle hatches are weatherstripped and insulated.
Final Walkthrough
We walk the attic with you showing full coverage before closing out the job.
Why It Matters
Open-Cell vs. Closed-Cell in an Attic
For most Las Vegas roofline applications, we lean toward closed-cell foam on the underside of the roof deck, converting the attic into semi-conditioned space.
Open-cell foam is a strong, lower-cost option for sound dampening and air-sealing in attic floors or interior partition walls.
