External Render

A range of high performance exterior render only systems are available that offer levels of weatherproofing and crack resistance unmatched by conventional cement-based render technology.

• PermaRend is the leading brand of mineralic, polymer-modified cementitious render systems. In addition to being highly resistant to impact damage, PermaRend renders are weatherproof, waterproof and water vapour permeable, allowing structures to breathe.
• ThermaRend is a unique high build, low density render system with excellent adhesion to most substrate types. The unique formulation, incorporating polystyrene spheres in a cementitious matrix, gives the material significant heat loss reduction properties, enabling the use of this material as an insulating render.
• PermaRock Scratch Render is a high quality textured render based on natural limestone sand that can be used to provide a naturally textured ‘scraped’ finish or to create traditional stone effects including rustication, ashlar and simulated blockwork. Scratch Render is available in a range of natural mineral shades and can be produced in special colours to order, subject to minimum order requirements.
