A Family-Owned Spray Foam Company Focused on Quality, Not Sales Tactics

NW Spray Foam & Insulation is a locally owned, family-run company based in North Idaho. The business started in 2015, and in 2020 it became fully owner-operated by our family.
When you call us, you’re not talking to a sales rep or a call center. You’re talking directly to the people who run the company. Jennifer handles quotes, scheduling, and communication, and Rylan is on job sites making sure the work is done right.

Our approach is simple:

  • We’re honest about what you actually need.
  • We don’t push expensive upgrades just to increase the price.
  • We use high-quality materials and equipment.
  • We show up when we say we will.
  • We leave the job site clean and ready for the next trade.
Most of our projects involve custom homes and high-end residential construction where performance, comfort, and long-term efficiency matter.

High-Performance Spray Foam Systems for Homes, Shops, and Commercial Buildings

Spray foam isn’t a one-size-fits-all product. It has to be installed correctly, in the right locations, and as part of a complete insulation system.

Spray Foam for Walls, Crawl Spaces, and Cathedral Ceilings

We install spray foam in:

  • 1. Exterior walls
  • 2. Crawl spaces
  • 3. Cathedral ceilings
  • 4. Rooflines
  • 5. Shops and metal buildings
In many modern homes, certain areas must be spray foamed to meet performance goals. We start with those areas, then build the rest of the insulation system around them.

Hybrid Insulation Systems for Better Performance and Cost Control

In many homes, the best solution is a hybrid system. We often combine spray foam with:

  • 1. Fiberglass batt insulation
  • 2. Blown-in fiberglass
  • 3. Rock wool
Spray foam handles air sealing and structural rigidity, while other materials can improve sound control and reduce overall cost.

What You Should Know Before Choosing Spray Foam

Spray foam is one of the best insulation options available, but it needs to be installed correctly.

Here are a few things we explain to every customer:

  • Our foam is rated at about R-7 per inch.
  • It adds structural strength to the building.
  • It helps stop air movement and improves comfort.
  • For sound control, we often recommend a hybrid system.
Off-gassing issues usually only happen when foam is installed incorrectly.
Our installers are trained and certified to apply the product properly. We stay educated on products, codes, and installation methods so your project is done right the first time.
