109mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside of Unilin Plydeck features a gas-tight foil membrane, providing a reliable moisture barrier.
2. Continuous vapour control layer: When bedded onto a mastic layer, the panel establishes a continuous vapour control layer that effectively regulates moisture transfer.
3. Water-resistant: Unilin Plydeck resists water absorption, making it well-suited for damp conditions and wet environments.
4. Low thermal conductivity: The insulation core exhibits low thermal conductivity, enabling thin board profiles whilst maintaining thermal efficiency.
5. Rapid coverage and straightforward installation: The composite board structure facilitates quick installation and broad coverage areas.
6. Enhanced thermal performance: For improved roof insulation, additional Unilin layers can be applied between joists or to optimise material thickness over structural members.
7. Durability: Unilin Plydeck is engineered to perform throughout the entire service life of the building, delivering consistent long-term reliability.
8. Lightweight and robust: The material combines light weight with structural strength, facilitating handling during installation, and can be cut with a saw or sharp knife for site adjustments.

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.
