Cathedral ceilings—sloped ceilings that follow the roofline with no attic space—create unique insulation challenges: limited cavity depth, condensation risk from warm interior air contacting cold roof deck, and building code requirements that mandate either ventilation or specific unvented assembly strategies. Closed cell spray polyurethane foam has become the dominant solution for cathedral ceiling insulation because [...]

Spray foam insulation solves the unique challenges of metal buildings—condensation control, irregular substrate surfaces, and severe thermal bridging—better than any alternative insulation system. Whether you're insulating a pre-engineered metal building (PEMB), agricultural pole barn, or corrugated Quonset hut, spray polyurethane foam delivers superior air sealing, thermal performance, and moisture management. This guide covers why spray [...]

Crawlspace encapsulation is one of the highest-margin, most repeatable services for insulation contractors—but only if you systematize the workflow to run 5-10 jobs per week without sacrificing quality or code compliance. This production-focused guide covers the technical decisions (open vs. closed cell, conditioning vs. venting), equipment setup for tight access, vapor barrier integration, and IRC [...]

Spray foam insulation is the preferred thermal and moisture control system for cold storage facilities, refrigerated warehouses, walk-in coolers, and freezer rooms because it delivers superior R-value per inch, eliminates air infiltration, and controls vapor drive in extreme temperature differentials that would destroy conventional insulation systems. This guide covers the technical requirements for specifying and [...]

Spray foam insulation in commercial cavity walls delivers unmatched air sealing and thermal performance, but spec'ing and installing it correctly requires understanding wall assembly types, climate zone requirements, fire code compliance, and vapor control strategies that differ significantly from residential applications. This guide walks through the technical decisions contractors and spec writers face when installing [...]

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 [...]
