129mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside features a gas-tight foil membrane, providing a dependable moisture barrier.
2. Continuous vapour control layer: When bedded onto a mastic layer, the panel creates a continuous vapour control layer that regulates moisture effectively.
3. Water-resistant: Unilin Plydeck resists water absorption, making it well-suited for damp conditions.
4. Low thermal conductivity: The insulation's low thermal conductivity permits thin board dimensions whilst maintaining thermal efficiency.
5. Rapid installation and coverage: The composite board structure allows for swift installation and broad coverage.
6. Enhanced thermal performance: Additional layers of Unilin can be installed between joists or over joists to optimise roof insulation performance.
7. Durability: Unilin Plydeck is engineered to perform throughout the building's service life, delivering reliable long-term results.
8. Lightweight and robust: The material combines light weight with structural strength, enabling straightforward handling on site and easy cutting with standard tools for precise fitting.

Roof Design

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

Falls

A flat roof requires consistent falls with sufficient gradient to prevent water pooling.
