Spray Foam Insulation
Our BASF polyurethane spray foam creates an airtight barrier with an R-value of 6.9 per inch. This closed-cell system prevents air leakage, improving energy efficiency and structural integrity. Ideal for attics, walls, and commercial spaces, it meets Washington State Energy Code requirements while reducing heating and cooling costs.
Blown-In Blanket System
The Blow-In-Blanket System fills cavities with fiberglass, eliminating gaps around wires and pipes. Installed behind mesh fabric in new construction or retrofitted in existing homes, it ensures uniform coverage. Combines with spray foam in hybrid systems for optimal thermal performance in residential and commercial buildings.
Energy Efficiency Upgrades
We enhance building performance through insulation retrofits and blower door testing. Our upgrades reduce energy consumption, lower utility bills, and improve indoor comfort. Certified technicians identify air infiltration points and implement solutions compliant with state energy codes for residential and commercial properties.
Eco-Friendly Insulation
Knauf EcoBatt fiberglass uses ECOSE Technology, a bio-based binder free of formaldehyde and petroleum chemicals. Cellulose and fiberglass batt options carry LEED and GREENGUARD certifications. Our sustainable materials reduce environmental impact while maintaining superior thermal and acoustic performance for homes and businesses.

I would not recommend them, because they charged too much for a return trip when they did very little and, Amy was rude and didn't have the courtesy to return my calls.

Report
Coast insulation did my new construction project consisting of a main residence and detached garage and apartment. Clark was responsive and helpful with all my questions, and their crew showed up on time and completed the job efficiently and with care and attention to detail. I was working on the house while the insulation crew was there, and during conversation with one of the crew learned they appreciate working at Coast over another insulation company because they treat their employees well. In my experience, happy employees do better work.
