California Metal Building Insulation

In California, manufacturing and agriculture make up a large portion of the state’s economy. In fact, among all 50 states, California ranks highest in economic production. Worldwide, California is tenth when compared to other countries in terms of the value of goods and services its economy produces.

There are hundreds of major manufacturing companies based in California, including those that specialize in everything from vehicles and aircrafts to electronics, elements, and metals.

When it comes to agriculture, California is America’s powerhouse. About ¾ of the state’s agricultural activity is in crop production, while the other ¼ is in livestock. But no matter the industry or the materials being produced, all companies in this industry have one thing in common: they need structures to aid in the processing, storage, and distribution of their goods.

Even though California’s average temperatures are quite moderate, different products and commodities need various ideal temperatures for storage and processing. With energy costs in California on the rise, it’s important to have a metal building structure with proper insulation that will help to both lower your energy costs and keep your commodities in peak condition.

Customer Testimonials

Very happy with my purchase here. I was lost as far as how to insulate my metal building. I almost pulled the trigger on just doing foam boards you buy Home Depot, but found this company through a colleague.

The price for their insulation was about the same as it would have been for the foam boards but the R-value was better and it was all custom-cut for my building.

Installing the batts was a learning process, especially for the roof. You can certainly do it as a one-man band, but it’s going to take some time and little tricks to make it work.

The insulation is very high quality, and I can absolutely tell a difference inside my shop!

I purchased insulation for my Barndominium in Malad ID, about 6 years ago and they provided me with a fantastic product that was made exactly to my specs. Swenson really took care of me. It is a bit of a drive but I was down there again last week #CustomerForLife.

Frequently Asked Questions

What is the best type of insulation for a metal building in California?

CMI’s faced fiberglass blanket is top-rated for California’s varied climates, from coastal moisture zones to Central Valley heat. The reinforced facing acts as a vapor barrier, shields against condensation, and installs quickly with custom-cut, color-coded rolls. No stapling needed. Spray foam or polyiso boards can supplement in high-heat or high-dry areas, but the blanket system strikes the optimal balance of cost, installation ease, and performance.

How do I insulate a pre-existing metal building in California?

Choose the Right System:

Choose CMI’s retrofit system with custom-cut faced fiberglass blankets
Slide rolls between purlins to fully fill the cavity.
Seal all seams, edges, and penetrations with tape or mastic to prevent moisture intrusion.
Optionally finish interior with liner panels or drywall for code or aesthetics.

What is the best R-value insulation for metal buildings in California?

Walls: Use an R25 fiberglass blanket to fill the girt cavity and then cover the unfaced fiberglass with a vapor barrier Liner System like Simple Saver.
Roof/Ceiling: Climate Zones 2–5 require at least R‑30–38 in ceilings.

These values align with California’s Title 24 and are modeled by IECC.

We proudly serve all states throughout the United States, including Arizona, Colorado, Idaho, Montana, Nevada, North Dakota, South Dakota, Utah, and Wyoming, among others.
