Substrate Preparation
The substrate must be clean, dry and dust free. It then needs to be primed using the Water Based Primer, which will help reduce the absorptive capacity of the substrate.
Starter Track & Clip-on Profile
The starter track is attached to the substrate above the DPC. This provides a level surface for the insulation to sit on; it also protects the base of the insulation against damp.
Adhesive
The insulation is fixed to the substrate using the EWI-225 Premium Basecoat. This is the strongest basecoat-adhesive in the EWI Pro catalogue, offering a long-lasting and secure adhesion. The adhesive is applied to the back of the insulation boards which are then secured to the wall.
Kingspan K5 Insulation
Kingspan K5 insulation easily upgrades the thermal properties of the building, ensuring a reduction in thermal transfer. Kingspan K5 is a premium insulation board and is an ideal solution for when space is limited.
Mechanical Fixings
Mechanical fixings are used as a secondary method of securing the insulation to the substrate. Metal fixings should be used for Kingspan K5 insulation.
Basecoat
The basecoat reinforcement layer is applied to the surface of the insulation boards and consists of the EWI-220 Adhesive or the EWI-225 Premium Adhesive. The reinforcement layer creates a smooth surface before applying the render.
Fibreglass Mesh
Fibreglass reinforcing mesh is embedded within the basecoat adhesive to enhance the tensile strength and crack resistance of the render system.
Render Primer
The render primer is painted onto the reinforcement layer to ensure that the render adheres to the basecoat, and to contribute towards a durable render finish.
Decorative Finish
EWI Pro offer a range of coloured renders, all of which can enhance the external appearance of the property. Each render provides a long-lasting, crack-proof finish and come with a range of advantages for the building structure.

Kingspan K5 System
Kingspan K5 is a premium phenolic insulation board for external wall insulation systems, part of the EWI Pro space-saving system. You should install the boards with EWI-225 Premium Basecoat for maximum structural stability as well as, Metal Pin Fixings to achieve an advanced insulation system with minimised thermal bridging and a prolonged lifespan. A choice of decorative thin coat renders are available to seal the system and achieve an aesthetically pleasing finish. When installed on a solid brick wall, 70mm of Kingspan K5 can achieve a U-value of 0.20W/(m2k). This brings the building fabric in line with modern-day efficiency standards, effectively reducing energy bills and improving the thermal comfort of the property. Not only does the system create a more comfortable internal environment, but it also hugely updates the exterior look of the building, creating a fresh, modern finish.
