Next-Generation Insulated Structural Exterior Sheathing

KRATOS™ MX7 is a dual-layer structural exterior sheathing that combines a mineral magnesium oxide (MgO) board with integrated EPS insulation. It delivers structural strength, fire resistance, thermal performance, and moisture control in a single high-performance panel—reducing labor, materials, complexity, and waste, lowering costs and accelerating installation compared to traditional wall assemblies.

One Panel. Multiple Performance Layers. Fewer Risks. Faster Installation.

MgO Structural Board

• Non-combustible inorganic mineral composition
• Provides impact resistance, structural shear, racking resistance, and fastener pull-through and pull-out
• Fire-Rated Performance Suitable for 3-Hour Assemblies
• Moisture-resistant, mold-resistant, rot-resistant

MX7

EPS Thermal Layer

• Continuous insulation creates a true thermal break
• Reduces thermal bridging through steel, concrete, or wood framing
• Acts as an air and moisture barrier
• Adjustable R-values to meet climate requirements
• Treated to protect against termites and other pests

Why MX7 Performs Better

Multiple Performance Benefits in a Single Panel

Fire
Resistance

  • Enhanced fire protection for wall assemblies.

Durability

Durability

  • Resistant to rot, mold, mildew and termites/insects. Built for long-term durability and resilience.

Structural Performance

Structural Performance

  • High shear strength and greater fastener holding capacity.

Sustainability

Sustainability

  • Low carbon footprint with reduced material usage and increased lifespan.

Faster Installation

  • Fewer layers, fewer steps, and fewer components help streamline construction and accelerate installation.

Lower Build Cost

  • Consolidating multiple wall components into a single panel helps lower material, labor, and overall construction costs.

Why Builders Are Moving Away from Wood / OSB Sheathing

Wood

MX7

WOOD

  • fire damage

Burns. Collapses. Code risk.

Combustible lumber feeds structural fires.

MX7

  • non-combustible

Holds structure under heat.

Steel framing meets fire-rated assembly requirements.

WOOD

  • Termite Damage

Eaten. Hollowed. Compromised.

Termites and rodents degrade wood from within.

MX7

  • pest-proof

Inorganic. Nothing to eat.

Steel is immune to termites, rodents, and insects.

WOOD

  • mold risk

Absorbs. Warps. Molds.

Water damage and mildew compound over time.

MX7

  • moisture-proof

Rejects water. No mold or mildew.

Steel + closed-cell foam create a full air/water barrier.

WOOD

  • inconsistent

Cracks. Splits. Warps.

Every board varies. Every wall pays the price.

MX7

  • precisely-engineered

1/16" tolerance. Every panel.

CNC-fabricated for consistency across every build.

KRATOS™ mx7

Combustibility

  • Highly combustible
  • Non-combustible mineral sheathing

Fire Rating

  • No inherent fire rating
  • Suitable for 1- and 2-hour fire-rated assemblies

Moisture Resistance

  • Absorbs water, swells, delaminates
  • Moisture-proof, inorganic, no swelling

Mold / Mildew

  • Supports mold and fungus
  • Fully inorganic — mold-resistant

Termites / Insects

  • Vulnerable (requires continuous treatment)
  • Insect and termite resistant

Durability

  • Degrades over time
  • Long-term stability, no rot

Impact Resistance

  • Low to moderate
  • High-impact exterior-grade surface

Air & Water Barrier

  • Requires additional wraps
  • Integrated impermeability — no need for extra building wrap

Thermal Bridging

  • No thermal break
  • Integrated Continuous Insulation layer (Thermal Break)

Thermal Conductivity

  • K-value: ~0.80 Btu·in/hr·ft²·°F
  • K-value: 0.43 Btu·in/hr·ft²·°F

Resistance To Heat Flow

  • R-value/Inch @ ~1.25
  • R-value/Inch @ ~4 to 5

Structural Capacity

  • High
  • High

Environmental Profile

  • High carbon footprint (wood, adhesives, resins)
  • Low-carbon footprint - Magnesium mineral panel

Longevity

  • Limited, dependent on maintenance
  • Long service life — inorganic materials

Installation

  • Multiple layers required
  • Single high-performance panel replaces multiple layers

Cost Over Time

  • Higher maintenance + replacements
  • Lower TCO (Total Cost of Ownership)
