Why was XPS insulation used below damp proof course (DPC) on this project?
XPS insulation was used below DPC level because on this project “External Wall Insulation – West Wickham” it offers high resistance to moisture and ground contact. This makes it suitable for protecting lower wall areas while maintaining long-term insulation performance.
Why was mosaic render selected at plinth level?
Mosaic render for external wall insulation – west wickham was selected for the plinth area due to its durability, impact resistance and ease of maintenance. It also helps protect areas exposed to splash-back while providing a clean visual finish.
How are window sills, drip details and window reveals handled?
Window sills, drip details and reveals are carefully detailed to ensure proper water run-off, weather protection and a neat, long-lasting finish. Where needed, sills can be extended using suitable oversills to suit the new finished thickness.
How should the new external wall insulation be cared for?
External wall insulation systems require minimal maintenance. Occasional gentle cleaning and visual checks are usually sufficient to keep the render clean and performing well.
Can I jet wash the render or reattach hanging baskets?
High-pressure jet washing is not recommended, as it may damage the render surface. Hanging baskets and light fixtures can usually be refitted using suitable fixings designed for insulated systems — we’re happy to advise.
