Close Cell Spray Foam Insulation

Your Reliable Solution for Maximum Efficiency and Structural Strength

Close-Cell Insulation

Built for Residential Durability & Commercial-Grade Efficiency

Residential Use

Closed-cell spray foam is ideal for homeowners seeking long-term insulation with additional moisture and structural protection. It creates an airtight, energy-efficient barrier in critical areas, improving indoor comfort and lowering utility bills. Its durability makes it perfect for harsh climates, where homes face temperature swings, moisture buildup, or wind-driven rain.

Common residential applications include:

Attics and roof decks
Crawl spaces and rim joists
Basement walls
Exterior wall cavities
Garages and bonus rooms over garages

Commercial Use

In commercial environments, closed-cell spray foam insulation is valued for its performance, durability, and energy-saving benefits. It helps businesses meet building codes, reduce operating costs, and improve the longevity of structural materials. Its air-tight properties also make it ideal for regulated environments.

Common commercial applications include:

Metal warehouses and storage buildings
Cold storage and refrigeration units
Commercial roofing systems
Office walls and ceilings
Manufacturing and distribution centers

Close-Cell Spray Foam Insulation

Closed-cell spray foam insulation is a powerful insulating material sprayed as a liquid, which rapidly expands and hardens into a dense, air-sealing foam. Unlike traditional insulation like fiberglass or cellulose, closed-cell foam creates a solid barrier against air, moisture, and even sound. Its tightly packed cell structure makes it more rigid and effective than open-cell foam, offering superior insulation and structural support.

Why It Matters: Key Performance Advantages

Exceptional Insulation Value

With one of the highest R-values per inch, it provides outstanding thermal resistance, keeping your home warm in winter and cool in summer.

Moisture and Air Sealant

It effectively seals cracks, gaps, and crevices where air and moisture might enter, helping prevent mold, mildew, and drafts

Adds Structural Integrity

Once cured, closed-cell foam becomes very rigid, adding extra strength to walls, ceilings, and roofs, making it ideal for areas prone to high winds or shifting foundations.

The Process

The installation process of closed-cell spray foam insulation is both technical and precise. It starts with careful preparation, where professionals protect non-target areas and wear safety gear to handle the chemical spray. Then comes the application phase, in which two liquid chemical components (isocyanate and polyol resin) are mixed through a spray gun and applied to the surface. Almost instantly, the foam expands and hardens, tightly adhering to the material and filling in all gaps and voids. Finally, any excess foam is trimmed, and the workspace is cleaned to complete the job.

Preparation – Technicians clear and mask the area, and wear protective gear to handle the chemicals involved.
Application – The two chemical components are mixed and sprayed onto the surface where they create a foam that is dense and has high R-value
Expansion and Setting – The foam quickly expands into all gaps, cracks, and cavities, filling large areas with ease.
Trimming and Cleanup – Once hardened, the foam is trimmed to fit, and the space is cleaned.
