Hunter Xci

Hunter Xci Hunter Xci is the brand name for the exterior continuous insulation polyiso wall product line manufactured by Hunter Panels.

Hunter Panels manufactures a full line of energy efficient polyisocyanurate insulation, XCI, used in commercial wall assemblies. XCI products are available utilizing facers that provide excellent fire and moisture resistance. Polyiso insulation is the most efficient insulation type to meet the new "CI - Continuous Insulation" required by the new energy codes. Polyiso is:

Highest R-Value per i

nch of any insulation
Energy Star Approved,
contributes towards LEED certification credits,
HCFC, CFC, zero ODP, and negligable GWP. Hunter Panels has six, state-of-the-art manufacturing facilities within the United States, and plant seven is opening in the Pacific Northwest in 2011.

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
