Foam Types

Closed-Cell vs. Open-Cell

We install both types and will recommend the right one based on your application, climate, and performance goals.

Highest Performance

Closed-Cell Spray Foam

The highest R-value insulation available at R-6.5 per inch. Creates a rigid, structural barrier that also acts as a Class II vapor retarder. Best for exterior walls, rooflines, crawl spaces, and any area exposed to moisture or extreme temperature swings.

R-6.5 per inch — highest available
Class II vapor retarder — moisture resistant
Adds structural rigidity to walls and rooflines
Does not settle, shift, or degrade over time

Cost-Effective

Open-Cell Spray Foam

A softer, lighter foam that expands to fill all irregular cavities. Lower cost per square foot than closed-cell, while still providing excellent air sealing and soundproofing. Best for interior walls, attic floors, and applications where vapor permeability is desired.

R-3.7 per inch — fills all irregular gaps
Excellent soundproofing between living spaces
More cost-effective for large interior areas
Vapor-permeable — appropriate for wood framing

Where We Apply It

Every Application, Done Right

Attic & Rooflines

Spray foam applied to the underside of roof decking creates an unvented attic that keeps HVAC equipment in conditioned space — massive energy savings in Central Valley heat.

Exterior Walls

Closed-cell foam fills stud cavities completely — no gaps, no settling. Ideal for new construction and gut-renovations where walls are open.

Crawl Spaces

Closed-cell foam on crawl space walls and rim joists eliminates the #1 source of cold floors and moisture infiltration in older homes.

New Construction

Spray foam at the framing stage eliminates air leaks before they're ever sealed in. Common spec for custom homes and production builds targeting energy certifications.

Commercial & Industrial

Warehouses, cold storage, and metal buildings benefit enormously from spray foam. Eliminates condensation, controls thermal bridging, and achieves energy code compliance.

Rim Joists & Band Boards

The most air-leaky spot in most homes. Closed-cell foam at rim joists is a quick, cost-effective improvement that delivers immediate comfort and energy savings.

The Process

From Estimate to Complete Coverage

1

Free Site Assessment

We inspect the area, identify air leakage points, and measure for coverage. You get a written scope and quote within 24 hours.

2

Foam Type & Prep

We confirm open-cell or closed-cell based on your application, protect surrounding areas, and stage equipment. The area is cleared and prepped before any foam is applied.

3

Application

Our certified applicators spray in controlled lifts to correct thickness. Coverage is uniform — no voids, no missed areas, no cold spots.

4

Verify & Document

We verify thickness and coverage before we leave, clean up completely, and hand you written documentation of installed specs.
