Supersub Panel System
SuperSIP™ Panel Specifications
Factory-manufactured structural insulated panel system with composite structural skins bonded to a continuous insulated core.
Composition Section
SuperSIP™ Panel Composition
Each panel is formed from structural skins bonded around an insulated core, creating a rigid panel with consistent thickness, strength, and thermal performance.
Key Components of SuperSIP™ Panel
01
Structural Skins
Triboard skins provide strength and a stable substrate.
02
Insulated Core
Fire-retardant EPS delivers continuous insulation & stiffness.
03
Adhesive System
Polyurethane adhesive creates permanent composite bonding.
04
Jointing & Sealing
Splines, screws, tapes & sealants transfer loads.

Structural, Thermal & Fire Performance
Structural Performance
Test-backed structural capacities with engineering-led specification and Producer Statements where required.
Thermal Performance
Continuous insulation supports NZBC H1 energy efficiency and reduces thermal bridging.
Fire Performance
Demonstrates reaction-to-fire performance. Use tested systems for fire-rated assemblies where required.
Custom Panel Sizes & Manufacturing Capability
Standardised widths with custom lengths available
Pre-cut openings for doors and windows (design-dependent)
Factory-installed splines and labelled panels for assembly
Optimised for transport and predictable on-site workflow
