149mm Xtratherm Plydeck comes with the following characteristics:

1. Gas-tight foil membrane: The underside of Xtratherm Plydeck is faced with a gas-tight foil membrane, ensuring a secure barrier.
2. Continuous vapour control layer: When the panel is bedded onto a mastic layer, it forms a continuous vapour control layer, effectively managing moisture.
3. Water-resistant: Xtratherm Plydeck is not prone to absorbing water, making it ideal for use in damp environments.
4. Low thermal conductivity: The insulation has a low thermal conductivity, allowing for a thin board thickness without compromising its efficiency.
5. Rapid coverage and straightforward installation: Its composite board structure enables quick coverage and easy installation.
6. Enhanced thermal performance: For improved roof insulation, an additional layer of Xtratherm can be added between the joists or to reduce material thickness over the joists.
7. Durability: Xtratherm Plydeck is built to last for the entire service life of the building, ensuring long-lasting performance.
8. Lightweight and robust: The material is light and sturdy, making it easy to handle during construction, and can be worked with a saw or sharp knife for precise 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.
