159mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside features a gas-tight foil membrane, creating 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 ideal for moisture-prone environments.
4. Low thermal conductivity: The insulation's low thermal conductivity enables thin board thickness without sacrificing thermal efficiency.
5. Rapid coverage and straightforward installation: The composite board structure facilitates swift coverage and simple installation procedures.
6. Enhanced thermal performance: For improved roof insulation, additional Unilin layers can be installed between joists or to minimise material thickness over joists.
7. Durability: Unilin Plydeck is engineered to perform throughout the building's service life, delivering consistent long-term reliability.
8. Lightweight and robust: The material combines light weight with structural strength, facilitating easy handling during installation, and can be cut with a saw or sharp knife for precise fitting.

Roof Design

Consideration should be given to the recommendations of BS 4841: Part 3 and the certification of the chosen membrane manufacturer.

Falls

The fall on a flat roof should be constant and steep enough to ensure that rainfall does not pond.
