54mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside features a gas-tight foil membrane, providing a reliable protective barrier.
2. Continuous vapour control layer: When bedded onto a mastic layer, the panel establishes a continuous vapour control layer for effective moisture management.
3. Water-resistant: Unilin Plydeck resists water absorption, making it well-suited for damp conditions.
4. Low thermal conductivity: The insulation core offers low thermal conductivity, enabling thinner board specifications without sacrificing performance.
5. Fast installation and coverage: The composite board structure allows rapid installation and broad coverage.
6. Enhanced thermal performance: For improved roof insulation, additional insulation layers can be installed between joists or over existing joists to optimise thermal efficiency.
7. Durability: Unilin Plydeck is engineered to perform throughout the building's service life, delivering consistent long-term results.
8. Lightweight and sturdy: The material combines light weight with structural strength, simplifying handling during installation and allowing adjustment with standard cutting tools.

Roof Design

Refer to the guidance in BS 4841: Part 3 and the specifications provided by your chosen membrane manufacturer.

Falls

Flat roof design should incorporate consistent, adequate falls to prevent water pooling during rainfall.
