The 62.5mm Unilin Safe-R SR/TB-MF Phenolic Insulated Plasterboard represents a composite insulated panel that consists of a 50mm phenolic pir insulation core combined with a composite foil facing. This foil facing is securely bonded to 12.5mm tapered edge plasterboard, intended for use in internal walls, sloped roofs, and ceilings. It's important to note that the SR/TB panel is specifically suitable for mechanically fixed applications.
Notably, the composite foil facing is present on both sides of the 62.5mm Unilin Safe-R SR/TB-MF Phenolic panel and includes an integrated vapor control layer. This feature plays a crucial role in minimizing the potential for condensation. The primary purpose of the 62.5mm SR/TB-MF panel is to deliver both high-level thermal insulation and drylining capabilities within a single process. As a result, it is a highly favored solution for both new construction projects and renovation endeavors.

The composite glass tissue facing on 62.5mm SR/TB-MF functions as a gas and vapor impermeable barrier, thereby reducing the risk of condensation. When the Xtratherm Safe-R SR/TB-MF 62.5mm joints are properly sealed and taped according to drylining best practices, a continuous vapor control layer is established.
Crucially, when drylining a wall, it is essential to incorporate fire stops at both the top and bottom of each board, as well as around all openings such as doors and windows. These fire stops consist of unbroken lines of adhesive and serve to prevent the intrusion of fire behind the insulation layer. Additionally, these unbroken adhesive lines aid in preventing thermal looping, contributing to an enhanced U-Value for the wall component.
Xtratherm PIR insulation Board should be stored above ground level on a clean, level surface, and must be sheltered from the elements. The polythene wrapping alone is insufficient protection against outdoor exposure. Careful measures should be taken to safeguard the insulation during storage and throughout the construction process. Adequate personal protective equipment (PPE) should be worn while handling insulation.
