Why Choose Spray Foam Insulation?

Spray foam expands to fill every nook and cranny, creating an airtight seal - so it is highly effective at preventing air leaks and improving energy efficiency.

It is durable, long-lasting, and doesn't sag or settle over time - ensuring consistent performance. Spray foam insulation adds structural strength to your home and is a barrier against moisture, pests, and allergens - contributing to a healthier living environment.

Benefits of Using Spray Foam Insulation in Custom Homes

Creates an airtight seal, preventing air leaks and minimizing heat transfer.
Reduces HVAC workload, leading to lower energy bills.
Air leaks can account for up to 30% of heating and cooling costs; spray foam significantly reduces energy consumption.
Effectively seals gaps and cracks in the building envelope.
Expands to fill every void, preventing air and moisture entry.
Higher initial cost but significant long-term savings.
Durable and long-lasting, reducing maintenance and replacement costs.

Cost Comparison

Insulation Type	Cost per Square Foot	Additional Benefits
Open-Cell Spray Foam	$1.50 to $3.00	Effective air sealing, noise reduction
Closed-Cell Spray Foam	$1.50 to $4.00	Superior thermal insulation, moisture resistance
Fiberglass	$0.40 to $1.50	Cheaper upfront, but requires frequent maintenance
Cellulose	$0.60 to $2.30	Prone to moisture issues, less effective sealing

Types of Spray Foam

Open-Cell Spray Foam

Open-cell spray foam is a lighter, less dense option - ideal for interior applications. It has a lower R-value (a measure of thermal resistance) than closed-cell foam but is highly effective at reducing noise and providing air sealing. Open-cell spray foam is also more flexible - allowing it to expand and contract with the building structure.

Closed-Cell Spray Foam

Closed-cell spray foam is denser and more rigid - suitable for both interior and exterior applications. The R-value measures thermal resistance, indicating how well a material insulates. A higher R-value means better insulation. Closed-cell foam has a higher R-value, providing superior thermal insulation. It is also more moisture-resistant, making it ideal for areas prone to dampness or water intrusion.

Professional Installation Required

Spray foam insulation requires professional installation to ensure it is applied correctly and safely. DIY installation is not recommended, as improper application can lead to issues with performance and safety.

Considerations Before Installation

First, assess your home's current insulation and identify areas needing improvement. This will help you determine the scope of the project and the type of spray foam insulation that best suits your needs.
Next, consider your budget. While spray foam insulation offers long-term savings, the initial cost can be higher than traditional insulation methods - so it's essential to weigh the upfront investment against the potential energy savings and increased home value.

Maintenance Tips

Once installed, spray foam insulation requires minimal upkeep - periodically monitoring your home's insulation is important to ensure it remains effective.

Regularly inspect it for signs of damage or wear - such as cracks or gaps - and ensure it stays dry and free from moisture, as dampness can compromise its performance.
Promptly address any issues to maintain optimal insulation conditions.
