Areas We Serve

Spray foam insulation is a material that expands upon application, creating an airtight seal in walls, attics, crawl spaces, and other areas of a building. It comes in two types: open-cell and closed-cell. Both types provide excellent insulation but have different characteristics, with closed-cell offering a higher R-value and added structural strength.

Spray foam is applied as a liquid and quickly expands to fill cracks, gaps, and cavities. As it hardens, it forms an airtight barrier, which reduces air leakage, increases energy efficiency, and improves temperature regulation inside your home or business.

• Open-cell spray foam is less dense and softer, making it ideal for interior walls and soundproofing. It allows some vapor to pass through but still provides excellent insulation.
• Closed-cell spray foam is denser, more rigid, and has a higher R-value. It is more effective for moisture control and structural reinforcement and is typically used in exterior walls, roofs, and areas exposed to moisture.

Yes, spray foam insulation is safe when installed by professionals. At Coastline Insulation, we use industry-approved materials that are non-toxic once cured. During installation, it’s recommended to vacate the area for a short period while the foam cures, but afterward, it poses no harm to occupants.

Spray foam insulation offers several key benefits:

• Energy Efficiency: It creates an airtight seal, reducing energy loss and lowering heating and cooling costs.
• Comfort: Improves indoor temperature regulation, making your home or office more comfortable year-round.
• Moisture Barrier: Helps prevent moisture infiltration, reducing the risk of mold and mildew growth.
• Air Quality: Seals out pollutants, allergens, and dust, improving indoor air quality.
• Durability: It lasts for many years without sagging or deteriorating.
• Noise Reduction: Provides soundproofing benefits by reducing noise transfer between rooms or from outside.

Spray foam insulation is highly durable and can last the lifetime of your home or building. Once installed, it doesn’t sag, settle, or lose its insulating properties over time, unlike traditional insulation materials such as fiberglass or cellulose.

The cost of spray foam insulation varies based on factors such as the type of foam used (open-cell vs. closed-cell), the size of the area being insulated, and the complexity of the project. While spray foam may have a higher upfront cost than other insulation types, its long-term energy savings and durability often make it a more cost-effective solution in the long run.

Yes, spray foam insulation significantly reduces energy bills by creating an airtight seal that prevents drafts and air leakage. By reducing the workload on your HVAC system, it helps maintain a consistent indoor temperature, which can lower heating and cooling costs by up to 50%.

Yes, spray foam insulation can be installed in both new construction and existing homes. For existing homes, the foam can be injected into walls, attics, crawl spaces, or other areas without major renovations.

Spray foam insulation can be considered environmentally friendly because it helps reduce energy consumption, lowering your carbon footprint. Additionally, many spray foam products are designed with environmentally responsible formulations that minimize the use of harmful chemicals.
