119mm Unilin Plydeck Flat Roof Insulation PIR OSB

119mm Unilin FR/TP Plydeck Thermal OSB is a composite insulated panel that merges Polyisocyanurate core technology with a composite foil face, securely bonded to 9mm OSB Board. This engineered solution delivers superior thermal insulation alongside decking performance in one integrated product, making it suitable for new construction and flat roof renovation work.

119mm 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, managing moisture effectively.
3. Water-resistant: Unilin Plydeck resists water absorption, making it ideal for use in damp conditions.
4. Low thermal conductivity: The insulation core achieves low thermal conductivity, enabling thinner board specifications without sacrificing thermal efficiency.
5. Rapid coverage and straightforward installation: The composite board structure facilitates swift installation and broad coverage.
6. Enhanced thermal performance: For improved roof insulation, an additional layer of Unilin can be installed between the joists or to reduce material thickness over the joists.
7. Durability: Unilin Plydeck is engineered to perform throughout the entire service life of the building, delivering consistent long-term results.
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.
