38mm Gyproc Thermaline PIR MR Insulated Plasterboard is a highly efficient board consisting of carefully designed components, offering not only insulation, but also vapour control and fire resistance. It consists of a rigid Moisture Resistant board bonded to a PIR foam insulant with a double control vapour layer, also offering fire protection of up to 30 minutes on timber constructions, in accordance with Euroclass B-S 1, d0. The product is also highly environmentally friendly, since having O ODP value and GWP value of less than 5. The Gyproc WallBoard is consisted of resilient paper liners that firmly hold the an aerated gypsum core which is incombustible when exposed to high temperatures, classified as material of limited combustibility, in accordance to the applicable Building Regulations. When installing the board, all the cuts necessary for installing socket boxes or switches should be done prior to fixing the board onto the wall, using adequate power tools, in accordance with the manufacturers instructions.

The product is used for wall framing vertical support in various systems, including:

  • DriLyner MF has the same characteristics and considerations as the previously explained DriLyner BASIC system, but is especially used for facilitating Gyproc plasterboards (or TheramLine laminates) fixing to the Gypframe channels (whereas this is done by using especially designed sealants and accessories in order of minimizing the risk of thermal bridges appearing), which have been previously bonded to the wall surface;
  • DriLiner RF can provide substantial insulation, reaching the U values of down to 0,21, particularly used for fixing the boards onto solid walls, including plaster wall when conducting a remodeling project, when special Gyproc sealants or blobs are used;
  • DriLiner SI uses the same advantages as the Basic system, but can achieve even better U values of 0,21. The system includes the use of gypsum adhesive dabs so that the boards can be fixed directly onto the wall, while improved insulation values are achieved by adding Gyproc TriLine, being a sound insulating laminate;
  • DriLyner TL uses adhesive dabs for direct bonding of the board onto the wall, in combination with the Gyproc TriLine laminate, for improved sound insulation, achieving U values of down to 0,22., providing early room comfort conditions.
  • GypLyner IWL, providing fire protection and fire resistance, used for upgrading both thermal and sound performance of masonry walls, designed to correspond to BS 5234 standards. The system can increase the sound and thermal insulation of both new or existing walls, only if the elements are well fitted to the background, junctions properly sealed and water penetration and damp issues taken care of by applying recommended measures;
  • GypLyner UNIVERSAL wall lining can be made to meet various requirements, both thermal and acoustic, especially applicable in refurbishment projects where the quality of the surface needs to be improved and the cavity accommodated to certain services such as water pipes. In order of meeting the requirements set by the applicable Building Regulations, proper cavity barriers should be installed and in order of improving the thermal performance of the surface, the cavity needs to be tightly sealed;
  • Load bearing - timber frame.


Gyproc Thermaline PIR MR Insulated Plasterboard is especially applicable to room-in-the-roof and refurbishment applications, wherever improving moisture resistance and thermal performance is of relevance.


The product is in compliance with the EN 13950: 2005.
