The InnovaPanel® Nail Base Insulated Roof Panel is a high-performance continuous insulation system designed for both new construction and existing roof retrofit applications. Available with either 5/8″ plywood or OSB facings, these insulated roof panels, also referred to as “SIP Sheathing”, combine structural sheathing and thermal insulation into a single product, making them an ideal solution for improving building energy efficiency while reducing installation time and labor costs.

The panel consists of a durable plywood or OSB nailing surface bonded to a closed-cell EPS insulation core. The underside of the panel features exposed insulation, allowing the panel to be installed directly over existing roof structures, roof sheathing, concrete roof decks, or roof framing systems.

Ideal for Roof Retrofit and Energy-Efficient Roofing Applications

Many existing buildings, especially those with low-slope or flat roofs, lack sufficient attic space to achieve modern insulation requirements. The InnovaPanel Nail Base Roof System provides a simple and cost-effective method of adding continuous insulation above the roof deck without removing existing roof sheathing.

Unlike traditional reroofing systems, the existing roof deck typically remains in place. The SIP Sheathing Panels are mechanically attached through the existing roof sheathing directly into the roof framing or trusses using engineered SIP fasteners. This approach reduces demolition costs, minimizes construction waste, and significantly shortens installation schedules.

Increase R-Value and Meet Modern Energy Codes

 InnovaPanel Nail Base Roof Panels allow architects, engineers, designers, and building owners to specify the insulation thickness necessary to meet or exceed current energy code requirements.

Available insulation options include:

  • Standard Closed-Cell EPS Foam
  • Neopor® Graphite Enhanced EPS Foam

Neopor® insulation can increase thermal performance by approximately 20% compared to standard EPS while maintaining the same panel thickness.

Benefits of SIP Sheathing include:

  • Higher roof R-values
  • Reduced thermal bridging
  • Lower heating and cooling costs
  • Improved building envelope performance
  • Increased occupant comfort
  • Reduced HVAC system sizing requirements
  • Support for Net-Zero building design

Air Sealing and Moisture Control

Beyond insulation, InnovaPanel Nail Base Panels provide a continuous air barrier layer that helps reduce unwanted air infiltration and exfiltration.

This enhanced air sealing contributes to:

  • Improved indoor air quality
  • Better humidity control
  • Reduced energy consumption
  • Increased occupant comfort
  • Improved building durability

By reducing uncontrolled air leakage, the building envelope becomes more efficient and easier to maintain throughout the life of the structure.

Applications:

InnovaPanel Nail Base Roof Panels are commonly used for:

  • Residential Roof Retrofits
  • Commercial Roof Retrofits
  • Flat Roof Insulation Upgrades
  • Low-Slope Roof Conversions
  • Metal Building Retrofits
  • Multifamily Housing Projects
  • Schools and Institutional Buildings
  • Net-Zero Energy Buildings
  • High-Performance Building Envelopes

SIP Sheathing Panels may be installed directly over:

  • Existing Roof Sheathing
  • Wood Roof Trusses
  • Steel Roof Framing
  • Concrete Roof Decks
  • New Construction Roof Systems

Benefits of InnovaPanel Nail Base Roof Panels

  • Continuous Insulation
    Eliminates thermal bridging and improves overall roof performance.

  • Faster Installation
    Installs directly over existing roof structures with minimal demolition.

  • Increased Energy Efficiency
    Reduces energy consumption and operating costs.

  • Improved Air Sealing

    Creates a tighter building envelope for better indoor comfort.

  • Flexible Design Options
    Available in multiple insulation thicknesses and densities.

  • Cost Savings
    Avoids expensive roof tear-offs and reconstruction.

  • Net-Zero Ready
    Supports energy-efficient and sustainable building design strategies.
    Whether upgrading an existing roof or designing a high-performance building envelope for new construction, InnovaPanel® Nail Base Insulated Roof Panels provide a practical, cost-effective solution for improving thermal performance, increasing R-value, and enhancing long-term building efficiency.
