ProGuard Exteriors completed a Northampton spray cork exterior transformation on a large detached property where the homeowners wanted to improve thermal performance while completely refreshing the exterior appearance of their home.

Overview

The property was a large detached home in Northampton. The homeowners were looking for an exterior refurbishment solution that would help improve wall performance while giving the property a cleaner, more modern finish.

External Wall Insulation was initially considered; however, due to the design of the property, a full EWI installation would have required extensive alterations and extensions to the existing rooflines. This would have significantly increased both the overall project cost and the level of disruption involved.

Our Response

As a more cost-effective alternative, the homeowners opted for a CorkSol spray cork coating system. CorkSol was selected to provide a modern, seamless finish while also offering additional thermal and weather-protection benefits without the disruption and structural alterations associated with a full external wall insulation installation.

Before applying the CorkSol system, ProGuard carried out the necessary preparation works, including a thorough pressure clean of the existing elevations and localised repairs to damaged or defective render areas. Once the substrate had been properly prepared, the CorkSol coating was professionally spray-applied across the property to create a consistent and durable finish.
