4″ & 5″ R-Seal Rigid Envelope Insulation Panel

PRODUCT OVERVIEW.

R-Seal is a comprehensive proprietary insulation system engineered for durability, precision, and energy performance.

The 4 inch R-seal envelope insulation and 5 inch R Seal panels are built with a high-density, closed-cell PUR/PIR foam core, providing outstanding R-values that meet or exceed the stringent energy codes in Ohio and the USA. These panels feature integrated air and moisture barriers, a clean uniform facer, and precise ship-lap joints that streamline installation and reduce thermal bridging.

They eliminate the need for batt insulation, banding, or multiple layers, helping you save time and labor while increasing the quality and durability of the final build.

Built for Roof & Wall Insulation Projects

One Panel. Two Functions. Zero Compromise.

Whether insulating a new warehouse’s roof or retrofitting an industrial facility’s wall insulation, the 4 and 5 inch R Seal panels are built to perform across multiple applications.

  • Install before cladding for early-stage protection
  • Structural rigidity eliminates the need for secondary framing
  • No fiberglass or banding required
  • Compatible with common metal building walls and roof systems
  • Ideal for cold storage, manufacturing, and institutional buildings

Looking for an all-in-one solution? These panels allow you to meet multiple performance needs, whether thermal, air, moisture, or fire.

Applications Across Ohio and the USA

These thicker panels are the go-to choice for builders, architects, and erectors working in energy-regulated or performance-sensitive markets, including:

  • Commercial and pre-engineered metal buildings
  • Cold storage and refrigerated warehouses
  • Food processing plants
  • Schools, hospitals, and government facilities
  • Agricultural buildings in rural Ohio
  • Industrial complexes with high energy usage

Installer-Friendly Design for Complex Jobs

We have engineered every detail of this system with the erector in mind:

  • Ship-lap joints align easily for tight seals and minimal taping
  • Rigid foam core maintains its structure during handling
  • PS facers are non-irritating and durable—no fiberglass itch
  • Lightweight panels reduce lifting fatigue
  • Pre-sized lengths mean fewer cuts, less waste, and faster finish times
  • Eliminates banding, vapor barriers, and extra framing steps

Panels can even be installed before final wall or roof systems are in place, allowing your crew to stay ahead of schedule, rain or shine.

Frequently Asked Questions (FAQs)

Q1: What’s the difference between the 4 inch R-Seal envelope insulation and 5 inch R Seal panels?

Both panels offer superior thermal performance and code compliance. The 5″ panel offers a higher R-value (R-37.5), making it ideal for colder climates or stricter energy codes.

Q2: Can these panels be used for the roof?

Yes. They’re designed for both walls and roofs in commercial buildings.

Q3: Are they good for retrofit projects?

Absolutely. They’re lightweight, easy to install, and available in long custom lengths.

Q4: Do I still need batt insulation or banding?

No. These are all-in-one panels with built-in air and moisture barriers.
