Weather resistant and breathable, the render provides a durable solution for the development, which is in an area severely exposed to wind-driven rain. Manufactured in the UK and certified by the British Board of Agrément (BBA), Monorex GM helps to prevent moisture build up, reducing the risk of structural damage.

Euan Barclay, Sika’s Business Development Manager – Building Finishing, said: “We worked collaboratively with Cala’s design team to develop a comprehensive site specification. It was vital the render tied in with the scheme’s overall design as well as its rural surroundings. “As Monorex GM is available in a variety of colours, Cala had the flexibility to select shades which complemented other exterior finishes, specifically the cladding and stonework that features on the new homes. The smooth finish was another important requirement to help fulfil both aesthetic and planning requirements.”

The Monorex GM render has been applied by Glasgow-based contractors, SLK Roofing, using mechanical spray equipment, providing a faster and more consistent installation while reducing waste.  Sika’s strong relationship with distributor Hamilton & Brydie also played a vital role in the project’s smooth delivery.  The streamlined procurement process ensured a fast and reliable supply to site, helping avoid delays and stay on schedule.
