Elastochem InsulthaneĀ® OCX Plus with X-PASS⢠Technology in action. š„
This isnāt just another open-cell spray foam. OCX Plus is a sucrose-free, non-halogenated formulation engineered for advanced fire performance while maintaining reliable, consistent processing in the field.
Designed to achieve AC377 Appendix X compliance without a prescriptive ignition-barrier coating, OCX Plus can help simplify qualifying attic and crawlspace applications. It also achieves a Class 1 (ASTM E84) fire rating without halogenated flame retardants.
For our builders, that means weāre continuing to bring new technology, quality materials, and proven building-envelope solutions to every project.

With this Texas heat, safety has to come first. āļø Some jobs may take us a little longer than normal as we make sure our crews are staying safe, hydrated, and taking the breaks they need. We appreciate all of our builders and customers for their patience and understanding during these hot days. We may slow down a little, but our standard doesnātāsafety first, quality always. šŖ

LETāS TALK CERTIFICATIONS ā AND WHAT THEY ACTUALLY MEAN. š
When you hear a spray foam contractor say theyāre certified or involved with industry organizations, what does that actually mean?
At JC Insulation, we believe education matters just as much as the equipment and material we bring to your home.
SPFA ā Spray Polyurethane Foam Alliance
SPFA is a national trade organization for the spray polyurethane foam industry. It provides technical resources, safety education, industry guidance, and professional training.
P*P ā Professional Certification Program
P*P is SPFAās certification program for spray foam professionals. It provides different levels of certification based on a personās role and requires education, testing, and demonstrated knowledge. It covers areas like proper application, equipment, chemical handling, jobsite safety, and spray foam best practices.
ICAA ā Insulation Contractors Association of America
ICAA represents insulation contractors and provides education, training, technical resources, and information on insulation and building performance. It goes beyond just spray foam and helps contractors continue learning about the entire insulation industry.
Spray Foam Worldwide
A spray foam industry community focused heavily on hands-on education, networking, events, demonstrations, and bringing contractors together to share knowledge and improve the trade.
Why does all of this matter to a homeowner or builder?
Because spray foam isnāt simply pulled out of a bag and installed. Weāre combining chemicals and essentially manufacturing the finished insulation on your jobsite. Temperatures, pressures, substrate conditions, thickness, ventilation, safety, equipment setup, and installer knowledge all matter.
Thatās why we continue going to classes, earning certifications, attending industry events, and learning from manufacturers and other professionals.
A certification hanging on the wall isnāt the end goal.
The goal is taking that knowledge back to every house we insulate.
More education. Better installs. Higher standards.
JC Insulation ā Raising the Standard.
At JC Insulation, weāre always trying to raise our own standard.
Itās not just about getting foam on the walls and roof. We care about making good foam, spraying it right, keeping the job clean, and making the finished product look good.
We love this industry, we love the craft, and weāre always trying to make the next job better than the last one.
