Application

Suitable for application onto masonry substrates, this system uses non-combustible mineral fibre insulation (webertherm MFD) and is finished with webersil TF, a silicone textured finish with enhanced water resistance which is available in over 100 colours.


Use multiple finishes on the same project:

This system can be used in conjunction with the webertherm XM brick system (MFD) for building designs which require a mix of brick and render finishes.

Description

[Formerly known as webertherm XM FMR024]


webertherm XM silicone system (MFD) is a traditional multi-layered external wall insulation system ideal for refurbishment projects to improve thermal performance and reduce interstitial condensation whilst providing the building with a rejuvenated façade.


This system uses non-combustible mineral fibre insulation and is finished with a silicone textured finish which is available in over 100 colours.


Suitability:

  • Suitable for use on buildings over 11 metres.

Final façade finish:

Reaction to fire:

  • A2-s1,d0 reaction to fire classification in accordance with BS EN 13501. Extended application report on request.
  • Incorporates non-combustible mineral fibre (webertherm MFD) insulation.

Certification & requirements:

  • BBA approved.
  • NSAI approved.
  • Able to satisfy PAS 2030:2019 and PAS 2035:2019 requirements.

Thermal performance:

Thermal performance for this system varies by substrate and insulation thickness, please refer to our U-value Estimator tool for more insulation thickness options.
