29mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The surface of Unilin Plydeck features a gas-tight foil membrane, providing an effective moisture barrier.
2. Continuous vapour control layer: When installed on a mastic base, the panel creates a continuous vapour control layer for effective moisture management.
3. Water-resistant: Unilin Plydeck resists water absorption, making it ideal for moist conditions.
4. Low thermal conductivity: The insulation core achieves low thermal conductivity, enabling thinner boards without sacrificing thermal performance.
5. Fast installation and coverage: The composite structure allows rapid installation and broad coverage.
6. Improved thermal performance: For enhanced roof insulation, additional Unilin layers can be installed between joists or over them to optimise thickness.
7. Long-lasting durability: Unilin Plydeck maintains performance throughout the building's lifespan.
8. Lightweight and strong: The material combines light weight with structural strength, simplifying handling and allowing easy cutting with standard tools.

Roof Design

Refer to BS 4841: Part 3 guidance and the specific membrane manufacturer's certification when designing your roof system.

Falls

Flat roof surfaces must have consistent and adequate fall to prevent water pooling.
