A Local, Veteran-Owned, Family-Run Insulation Company

NW Spray Foam and Insulation is a family-owned company based in North Idaho. We’ve been serving homeowners and contractors since 2015, and in 2020 we became fully owner-operated.
When you call us, you’re not dealing with a sales team or a franchise office. You’re talking directly to the owners. Jennifer handles quotes, scheduling, and communication, and Ryan is on job sites making sure everything is done right.
The full crew of four stands with their blue Ram service truck, which features the "Northwest Spray Foam" logo. Two members are in front of the truck while two others are in the truck bed, set against a scenic backdrop of forests and fields.
The company's branded trailer is parked on a dirt construction site in front of a large, impressive log home. The scene showcases the company's capability to handle high-end, custom residential projects in rustic settings.

We built this company around a few simple principles:

  • Be honest about what the customer actually needs
  • Use high-quality materials and equipment
  • Stick to the schedule we promise
  • Keep job sites clean and organized
  • Treat every project with the same level of care
We’re proud to be a veteran-owned company, and most of our work comes from referrals, repeat builders, and satisfied homeowners.
We proudly offer a 10% military discount as a thank you to veterans and active service members for their service.

Insulation Services for Homes, Remodels, and Commercial Projects

We handle complete insulation systems for a wide range of projects across North Idaho and nearby areas.

Spray Foam Insulation

High-performance spray foam systems for walls, crawl spaces, cathedral ceilings, rooflines, and metal buildings. Spray foam provides strong air sealing, structural rigidity, and about R-7 per inch.

Residential Insulation

Complete insulation packages for custom homes and shops. We design the system around the structure and performance goals, not just the cheapest materials.

Retrofit Insulation

Insulation upgrades for older homes, gut renovations, and additions. We help improve comfort, efficiency, and structural performance in existing structures.

Commercial Insulation

Spray foam and hybrid systems for warehouses, shops, and commercial buildings. Designed to control temperature, reduce condensation, and improve long-term durability.

Insulation Systems Designed Around Your Home or Building

When you call us, we usually start with three simple questions:

  • Is this your forever home or a short-term project?
  • How efficient do you want the building to be?
  • What kind of budget are you working with?

From there, we design an insulation system that may include:

  • Spray foam
  • Fiberglass batt insulation
  • Blown-in fiberglass
  • Rock wool
  • Hybrid combinations of materials
Our goal is to give you the right performance without spending money where you don’t need to.
