  • Provides reliable long-term energy savings for buildings
  • Is suitable for both new build and refurbishment projects
  • Can be easily used to upgrade to current building regulation standards
  • Can be used in pitched roof, flat roof and wall applications


Celotex PL4000 is purpose designed for providing thermal insulation and plasterboard as one product. PL4000 can be specified for use in a variety of applications including:

  • The 'underneath' layer of insulation in between and under rafter and joist applications
  • Solid masonry walls
  • Timber frame lining applications
