149mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside features a gas-tight foil membrane, providing a secure moisture 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 damp environments.
4. Low thermal conductivity: The insulation's low thermal conductivity enables thin board thickness without sacrificing performance.
5. Rapid coverage and straightforward installation: The composite board structure facilitates quick coverage and simple installation.
6. Enhanced thermal performance: For improved roof insulation, additional Unilin layers can be installed between joists or to reduce material thickness over joists.
7. Durability: Unilin Plydeck is engineered for the entire service life of the building, delivering long-term reliability.
8. Lightweight and robust: The material is light yet sturdy, facilitating easy handling during construction, 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.
