Xtratherm Plydeck is a composite insulated panel consisting of an 80mm Xtratherm Polyisocyanurate core with a composite foil face, bonded to 9mm OSB board. This advanced panel offers both thermal insulation and decking capabilities in a single application.
Application
Xtratherm Plydeck is designed to provide high levels of thermal insulation and decking in a single operation, suitable for both new and refurbishment flat roof applications. Approximately 16-20 Suretwist fixings are required per 1200x2400mm board, depending on rafter spacing.
Characteristics
- Xtratherm Plydeck features a gas-tight foil membrane on its underside
- Bedding the panel onto a layer of mastic creates a continuous vapor control layer
- Xtratherm Plydeck is resistant to water absorption, making it suitable for damp environments
- The insulation's low thermal conductivity allows for minimal board thickness, while the composite board offers rapid coverage and easy installation
- A second layer of Xtratherm can be added between joists to enhance thermal performance or reduce material thickness over joists
- Xtratherm Plydeck is durable and designed to perform throughout the building's service life
- Lightweight, robust, and easy to handle, Xtratherm Plydeck can be cut using a saw or sharp knife
Certification
- Manufactured under an ISO9001 assured quality system
- Manufactured using Pentane as the blowing agent, which is CFC/HCFC-free with zero ozone depletion potential and a Global Warming Potential less than 0.01
Note: Bonding of the Unilin Insulation board (formerly known as Xtratherm) with other materials may be made by Unilin or a different fabricator.
