39mm Unilin FR/TP Plydeck Flat Roof Insulation

39mm Unilin FR/TP Plydeck Thermal OSB is a composite insulated panel that merges Polyisocyanurate (PIR) core technology with a composite foil face, securely bonded to 9mm OSB Board. This integrated design delivers superior thermal insulation and decking capability in one product, making it particularly suitable for new construction and flat roof renovation applications.

39mm Unilin Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside features a gas-tight foil membrane, providing a secure protective 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 well-suited for damp environments.
4. Low thermal conductivity: The insulation core exhibits low thermal conductivity, enabling thin board thickness without sacrificing thermal efficiency.
5. Rapid coverage and straightforward installation: The composite board structure facilitates quick coverage and uncomplicated installation.
6. Enhanced thermal performance: For improved roof insulation, additional Unilin layers can be installed between joists or positioned to reduce material thickness over joists.
7. Durability: Unilin Plydeck is engineered to perform throughout the entire service life of the building, guaranteeing sustained performance.
8. Lightweight and robust: The material combines lightness with structural strength, facilitating easy handling during installation, and can be cut with a saw or sharp knife for custom sizing.

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.
