Barricade Thermo-Brace SIB

4-in-1 Reversible Structural Insulated Sheathing Solution

Durable, Cost-Saving, and Faster Installation

Exclusively using BASF Neopor® GPS (Graphite Polystyrene) rigid foam in conjunction with Barricade Thermo-Brace, Thermo-Brace SIB is a reversible, lightweight, 4-in-1 structural sheathing solution that provides four layers of enforced protection against water, moisture vapor, mold, and more. Thermo-Brace SIB is today’s energy-efficient and cost-effective insulative solution for architects, contractors, and builders.


1. BASF Neopor® GPS

Unlike polyiso and XPS, Neopor GPS doesn’t use HFC gas agents for R-value, which can deplete over time. XPS only retains 90% of it’s initial R-value over its lifetime and the R-value of Neopor GPS is up to 30% higher than EPS (white foam).

2. Thermo-Brace Structural Sheathing

Thermo-Brace is a fiberboard structural sheathing with a composite core that provides the structural strength required while offering a more water-resistant barrier than OSB. It costs less than OSB or ZIP System® and is lighter, easier to handle, cut, and install.

3. Thermo-Brace w/ Water-Resistant Barrier

Enhanced water-resistant barrier protection on the reverse side offers increased durability. The reversible installation feature provides the flexibility to choose whether this side faces outward or inward. Available in both reflective and non-reflective variants.




Our SIB products meet structural requirements with test results you can trust.



Two energy code options, R3 and R5, designed to resist conductive and convective heat flow with an outstanding thermal break system.



Meets AIB requirements while providing improved air barrier properties, increased indoor air quality, and fire resistance.



Replaces the need for an additional layer of outside WRB protection, yet still protects against rain, water vapor, heat, cold, and more.

    90 day UV exposure to unfaced foam
    1 year UV exposure to Thermo-Brace panel
  • Code Compliant Complies with 2012, 2015, 2018 and 2021 International Energy Codes & Neopor GPS is GREENGUARD certified for Gold Indoor Air Quality
  • Cost Efficient Stable pricing and material savings that reduce energy consumption
  • Faster, Easier Install Fewer materials mean lower costs, faster installation, and reduced labor costs
  • Lightweight structure can be used up to 24 inches on center while still providing protection and strength to your building

Product Specifications

Insulative R-Value

Two 2018 energy code options, R3 and R5, designed to resist conductive and convective heat flow via an outstanding thermal break system.

SIB is especially suitable for northern local energy codes requiring R5 continuous insulation on the exterior walls.


Both options can be used in place of OSB. R3 and R5 both meet structural requirements with test results you can trust.

Water Resistant

Replaces the need to add additional outside WRB protection – protects against rain, water vapor, heat, cold, and more.
