External Wall Insulation (EWI)
External Wall Insulation is an extremely effective means of insulating solid wall properties to significantly reduce the amount of heat lost through the walls. The installation process involves fixing a layer of Expanded Polystyrene insulation (EPS) material to the external walls of a property, and covering it with reinforcement and a special render in a range of decorative finishes. These products are applied onto a range of specialist insulations designed specifically for external wall insulation systems which can be applied to many different substrates.
ACRYLIC render system are available in an extensive range of colours, finishes and textures and can be adapted to meet the expectations and design requirements of the architect and designer. Using the anti-crack base coat technology provides excellent shock – proof resistance to impact.
DRY DASH render is a traditional render application commonly used. By this method, dry dashing aggregate is thrown onto the wet render to create a natural aggregate finish. Available in a wide variety of colours, sizes and textures.
MINERAL render systems offer a specially formulated mineral based render that can be applied to many different substrates. The finish retains the traditional appearance of a one coat render, with the advantage of a specially formulated top coat and anti-crack base coat technology. The system is available in a range of 48 standard colours, can receive a range of textured finishes with the added benefit that it is suitable for manual or mechanical applications.
