Description

Cellulose/ Fibre cement building board, specifically designed as a carrier board for polymer modified render systems where no insulation is applied to the board prior to rendering, for new timber frame rendered facades. For projects where insulation is applied first, RCM Cemboard, Multipurpose, Y-Wall or CEM+ are suitable alternatives.

Designed to achieve a strong key between polymer basecoats/ topcoats and the Renderflex. CE marked and conforms to BS EN 12467.

Key applications:

  • Render carrier board.
  • Internal and external wall linings.

Features:

  • Dimensional stability.
  • High tensile strength for long term durability.
  • Excellent weathering properties for exposure prior to render application.
  • Impact resistance.

Approved by many of the UK render manufacturers. Please contact RCM for further information.
