Johnstone’s offers a wide range of fully certified External Wall Insulation and Render systems. External Wall Insulation (EWI) is a highly effective way of insulating your home through the application of insulation panels to the exterior walls of a property and then coating these in a tough, durable and attractive render system.


Johnstone's has a long history as one of the UK's foremost professional trade paint brands and has enjoyed a presence in the market since 1890. It was for this reason that a natural progression into external wall coverings was the next step to expand the brand.


Here at Skimz we are happy to be and official supplier of the Johnstones Stormshield range.
