Join us for an upcoming webinar: Foam Plastic Insulating Sheathing – Delivering Energy Efficiency, Carbon Savings & More
Continuous insulation is more important than ever in meeting today’s energy, sustainability, and resiliency goals. This 1-hour webinar breaks down how foam plastic insulating sheathing (FPIS) supports code compliance, reduces carbon impacts, and enhances wall assembly performance.
Key takeaways include:
• How to use FPIS continuous insulation for energy efficiency and energy code compliance
• Practical, multi-functional applications to optimize building assemblies
• How FPIS contributes to carbon footprint and handprint reductions
• Actionable design and construction resources to support code compliance and performance objectives
