Serving Eagle and nearby communities.

Tight framing cavity. A wall that sits below grade. A garage wall that shares living space on the other side. These are the spots where closed-cell foam earns its keep. It's denser than open-cell, expands less, and resists moisture in ways open-cell can't match.

Eagle Spray Foam Insulation reaches for closed-cell when the application calls for strength and moisture resistance, not just thermal coverage. Idaho's temperature swings put real stress on tight cavities, and the higher R-value per inch matters when there isn't much depth to work with.

What's included

What's Included with Closed-Cell Spray Foam Insulation

Typically included: substrate prep, controlled multi-pass application to reach specified thickness, trimming to a flush finish, protective coating where code requires it, cleanup.

Optional: fire-rated topcoat on exposed interior surfaces, reinforcing mesh in specific structural applications.

Customer prep: clear the work area, note any known moisture history in the space, confirm access for equipment.

Closed-Cell Spray Foam Insulation

Closed-Cell Spray Foam Insulation Install Process

Surface Evaluation — We assess the substrate to ensure compatibility with high-density closed-cell foam application.
Temperature Control — Equipment is calibrated to maintain optimal spray temperature for proper foam expansion.
Layered Application — Foam is applied in controlled passes to achieve the desired thickness and density.
Structural Reinforcement Check — We verify that foam rigidity contributes positively to wall or roof structural performance.
Moisture Barrier Testing — The cured foam is tested to confirm it provides an effective moisture barrier.
Quality Inspection — A final inspection ensures uniform coverage and adherence to density specifications.

Materials

Materials and Methods for Closed-Cell Spray Foam Insulation

Below-grade spaces and shared walls in larger custom homes are where this material does its best work.

High-Density Closed-Cell Foam
Rigid and strong, holds up well in crawlspaces and rim joists exposed to seasonal moisture swings.
Two-Component Foam System
The on-site chemical reaction that builds the dense cell structure closed-cell is known for.
Reinforcing Mesh
Mesh used in certain applications to add structural support to foam layers.
Protective Topcoat
A sealant coating applied to protect foam from UV exposure and physical damage.
Thermal Barrier Coating
A code-compliant coating applied over foam in occupied spaces for fire safety.
Moisture-Resistant Primer
A primer applied to surfaces to improve foam adhesion in damp conditions.
