Monocouche Render

Monocouche Render is a through coloured cement render with quick and efficient application with the addition of water. We only use the best quality manufacturers to ensure our customers only receive the best finishes. Monocouche render is great for waterproofing and breathability to reduce damp issues.

Acrylic & Silicone Render

Thin Coat Silicone Render is very water resistant, strong and flexible external render coating that is available in over 1000 different colours. Silicone Render is also known as Acrylic Render or Thin Coat Render. It takes slightly longer to apply than Monocouche Render but it is more water resistant and flexible.

Sand & Cement Render

Sand and Cement Render is a more traditional style of rendering and would include Pebbledashing, Plain Faced Render and Tyrolean. Sand and Cement Render is much cheaper than silicone render or monocouche render, which means it can be the best options for customers who are on a limited budget.

External Wall Insulation

EWI (External Wall Insulation) is a great method of insulating a building without a cavity or solid wall construction. EWI Systems help to keep your home warmer and can be finished with either Monocouche render or a Silicone Render System. EWI can help you save money on your heating bills, giving you a return on investment.
