Xtratherm Plydeck is a composite insulated panel consisting of a 50mm Xtratherm Polyisocyanurate core with a composite foil face, bonded to 9mm OSB board. This innovative product provides both thermal insulation and decking in one application.

Application

Xtratherm Plydeck is designed to offer high levels of thermal insulation and decking in a single operation 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 vapour control layer
  • The insulation's resistance to water absorption makes it suitable for damp environments
  • The low thermal conductivity of the insulation allows for minimal board thickness, while the composite board enables rapid coverage and straightforward 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.
