Product Overview
Flat Roof Decking Plywood Insulation Panel with a 106mm thickness and 2400mm x 1200mm sheet size. This composite insulation deck combines a rigid PIR (polyisocyanurate) insulation core bonded to a 6mm plywood facing, creating a durable, thermally efficient substrate for flat roof construction.
The PIR core delivers low thermal conductivity for effective heat retention, while the plywood top layer provides a stable, load-bearing surface for direct membrane application. Designed for warm roof systems, it offers rapid installation and long-term dimensional stability.
The 106mm thickness achieves low U-values in modern warm roof applications, ideal for energy-efficient builds and compliance with current building regulations.
Features & Benefits
- Composite construction: Rigid PIR insulation core bonded to structural-grade plywood.
- Thermal efficiency: Low-conductivity PIR delivers reliable insulation for warm roof build-ups.
- Load-bearing surface: 6mm plywood face provides strength for mechanical fixing or membrane bonding.
- Moisture resistance: Closed-cell insulation core resists water absorption and maintains integrity.
- Fast installation: Factory-laminated board simplifies fitting and reduces roof build-up time.
- 106mm thickness: Delivers high insulation levels for energy-efficient roof designs.
Applications
- Flat roofing systems: Used as a thermal deck beneath single-ply, bituminous, or liquid-applied membranes.
- Warm roof construction: Provides continuous insulation above structural decks.
- Timber or steel structures: Compatible with both substrates for commercial or domestic projects.
- Energy-efficient roofing: Contributes to reduced heat loss and improved building performance.
Installation Guidance
- Preparation: Ensure roof deck is clean, dry, and structurally sound before installation.
- Fixing: Secure mechanically using approved insulation fasteners through the plywood face.
- Joint treatment: Stagger board joints; tape or seal where required by membrane specification.
- Finishing: Apply waterproof membrane directly to the plywood face in accordance with manufacturer guidance.
Compliance & Performance
- Thermal conductivity: PIR core rated at 0.022 W/mK.
- Fire performance: Plywood facing classified to relevant Euroclass standards; system performance dependent on full roof build-up.
- Dimensional stability: Maintains rigidity and integrity under load and temperature changes.
- Environmental compliance: CFC- and HCFC-free with zero ODP and low GWP.
- Important note: Ensure fixing pattern and membrane system comply with manufacturer installation and fire certification requirements.
