Spray foam insulation is a popular and energy-efficient solution for homeowners and businesses looking to improve insulation performance. One of the most common questions is: How much does it cost to spray foam for 1500 square feet? The cost depends on various factors, including foam type, labor charges, regional pricing differences, and specific project requirements. This guide provides a detailed breakdown of spray foam insulation costs in Olympia, WA, and what homeowners can expect when budgeting for this service.
Spray foam insulation comes in two main types: open-cell and closed-cell foam. Each has distinct characteristics, performance levels, and price points.
| Foam Type | Cost Per Square Foot | Typical R-Value | Best Use Cases |
| Open-Cell | $0.45 – $0.75 | R-3.5 to R-4.0 | Interior walls, soundproofing, attics |
| Closed-Cell | $1.00 – $2.00 | R-6.0 to R-7.0 | Exterior walls, basements, roofs |
For a 1500-square-foot area, the total cost varies significantly based on the type of foam used:
The thickness of the foam determines the insulation’s efficiency. Closed-cell foam requires less thickness to achieve a high R-value, making it ideal for exterior applications, while open-cell foam is often used for interior applications.
Professional installation rates vary by region. In Olympia, WA, labor costs typically range between $50 and $100 per hour. The complexity of the installation, including accessibility and prep work, can impact the final cost.
Raw material costs fluctuate due to supply chain factors and demand. Costs for materials have risen in recent years, affecting overall installation prices.
Some homes require additional preparation, such as removing old insulation, sealing air leaks, and preparing surfaces, which can add to the overall project cost.
Attics are a primary target for spray foam insulation to enhance energy efficiency.
Wall insulation is crucial for maintaining interior temperature stability.
These areas require moisture-resistant insulation, making closed-cell spray foam a preferred option.
