It's the gold standard for insulation performance — particularly in climates like Billings, Montana, where temperatures can swing 80°F+ between seasons and moisture control is critical to preventing structural damage.
Maximum energy savings: At R-6.5 per inch, closed cell delivers more insulation value per inch than any other product. In Billings winters, that means your furnace runs less and your bills drop significantly.
Built-in vapor barrier: Montana's temperature swings create condensation risk inside your walls. Closed cell foam stops moisture at the source, protecting your structure from rot and mold.
Structural rigidity: Closed cell foam bonds to surfaces and adds measurable racking strength to walls — particularly valuable in older Billings homes.
One-time installation: Closed cell foam doesn't sag, settle, or degrade. Install it once and it performs for the life of the building.
We recommend closed cell spray foam for:
• Exterior walls — maximum R-value in minimum thickness
• Roof decks and cathedral ceilings — vapor control in tight spaces
• Crawl spaces — seals ground moisture and cold air infiltration
• Rim joists — one of the biggest sources of energy loss in Billings homes
• Metal buildings and pole barns — prevents condensation and heat loss
• Garage walls and ceilings — especially for attached or heated garages
