99mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside features a gas-tight foil membrane, providing a reliable moisture barrier.
2. Continuous vapour control layer: When bedded onto a mastic layer, it establishes a continuous vapour control layer for effective moisture management.
3. Water-resistant: Unilin Plydeck resists water absorption, making it ideal for damp conditions.
4. Low thermal conductivity: The insulation core achieves low thermal conductivity, enabling thin board thickness without sacrificing performance.
5. Fast installation: The composite board structure allows rapid coverage and straightforward installation on site.
6. Enhanced thermal performance: Additional Unilin insulation can be layered between joists or over joists to optimise roof insulation performance.
7. Long-term durability: Unilin Plydeck is engineered to perform throughout the building's service life.
8. Lightweight and strong: The material is easy to handle and can be cut with a saw or sharp knife for site adjustments.

Roof Design

Refer to BS 4841: Part 3 recommendations and the certification requirements of your chosen membrane manufacturer.

Falls

Flat roof falls must be consistent and sufficient to prevent water pooling.
