Continuous insulation (ci) is one of the most effective strategies for meeting modern energy codes and reducing thermal bridging in commercial and high-performance residential buildings. As IECC 2021 and ASHRAE 90.1-2019 tighten prescriptive R-value requirements, more projects are turning to continuous insulation layers—and closed cell spray foam is emerging as a high-performance alternative to traditional [...]

If you've been specifying spray foam for the past decade, you've used HFC-blown closed cell foam. If you're specifying it today—or will be in the next 12-24 months—you need to understand the industry-wide shift to HFO (hydrofluoroolefin) blowing agents. This transition is driven by environmental regulation (specifically, global warming potential limits), and it's not optional. [...]

Fire safety is non-negotiable in commercial construction. Spray polyurethane foam (SPF) is a combustible plastic material, and building codes impose strict requirements on how and where it can be installed. Understanding ASTM E84 (surface burning characteristics), ASTM E119 (fire-resistance ratings), and UL assembly listings is essential for spec compliance and passing inspections. Here's what you [...]

If you're bidding a spray foam job or ordering material for a project, accurate yield calculations make the difference between profit and loss. A 55-gallon drum set might claim 4,000 board feet of coverage, but real-world conditions—overspray, substrate porosity, temperature swings, and applicator technique—can reduce that number by 15-30%. Here's how to calculate theoretical and [...]

When you're specifying insulation for a commercial build—whether it's a 50,000 sq ft warehouse, multi-story mixed-use, or cold storage facility—closed cell spray foam (ccSPF) consistently outperforms traditional insulation on multiple fronts. Here's why closed cell dominates commercial specs and how to apply it across common assemblies. Why Closed Cell Spray Foam Dominates Commercial Specs Thermal [...]

Rigid foam insulation (continuous insulation, or CI) is required by IECC in most climate zones for commercial buildings and increasingly common in residential construction. Choosing between XPS, EPS, and polyiso isn't about which is "best"—it's about which meets performance requirements and delivers the lowest lifecycle cost for the specific application. Here's the technical comparison builders [...]

Energy codes are tightening. Blower door testing is now mandatory in most jurisdictions. For production builders and contractors, spray foam isn't just about R-value—it's about achieving verifiable air leakage compliance and delivering measurable energy cost reductions that justify the material premium. Here's what the data actually shows: real blower door test results, climate-specific energy savings, [...]

Spray foam pricing is opaque until you start running volume. Retail pricing means nothing when you're bidding production work. Here's the real cost structure for contractors buying in bulk, plus the labor and equipment overhead that determines your true installed cost per board foot. This isn't consumer pricing—these are the numbers for insulation contractors, production [...]

Most insulation contractors default to drum systems for good reason—they're the workhorse of spray foam application. But dismissing kits entirely leaves money on the table. The question isn't which is "better," it's which delivers the lowest installed cost per board foot for each job type. Here's the framework we use when bidding insulation work: kits [...]
