We used to use K-Rend on all our projects, but we now use EWI Pro Supplied by EWI Store

Colour & Insulated Render

The reasons for this are as follows:


This one’s simple – EWI Pro’s renders are the best on the market. All of them have been specially designed to withstand challenging weather conditions and stand the test of time. There are five options, and all of them carry their own benefits:

  • EWI Pro Silicone Silicate Render is EWI Pro’s most popular render. It is breathable, self-cleaning and water-repelling.EWI Pro Mineral Render is breathable and quick-drying, making it ideal for installing in colder, more humid conditions. It may be possible to use during the cold winter months, when installing solid wall insulation would not normally be an option.
  • EWI Pro Acrylic Render is EWI Pro’s most durable render, suitable for use in heavily exposed areas prone to damage.
  • EWI Pro Silicone Render is the premium render in their catalogue. It is breathable, flexible and long-lasting. It is available in hundreds of different colours.

Colours and Sizing

EWI Pro has a huge range of colours and finishes to choose from, giving you huge control over the final appearance of your property. As external wall insulation is a long-term measure, we want you to be happy with the finish. EWI Pro can mix their renders in almost any colour with their state of the art mixing machines. Their through-coloured renders are brilliant, because they won’t show damage or scratches, unlike traditional render with coloured paint over the top.
