Wall Build-Ups

EWI Pro systems are built to last, offering a range of external wall solutions for improving thermal comfort and external appearance. The following are some typical external wall insulation systems using EWI Pro materials. As demonstrated, our systems are highly versatile and can be used to create numerous external wall insulation systems for a range of properties and substrates.

Substrate Preparation

The substrate must be clean, dry and dust free.

Parge Coat

A parge coat must be applied to the substrate to prime and level the surface. The EWI-269 Lightweight Basecoat can be applied up to 10mm thick to create a parge coat.

Basecoat

The basecoat reinforcement layer consists of the EWI-225 Premium Basecoat applied directly to the substrate. The adhesive is used to create a smooth surface before rendering.

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.

New Blockwork Render Only

EWI Pro render-only thin coat systems are highly versatile, offering a range of solutions for a broad variety of substrates including new blockwork. Our thin coat render systems are ideal for blockwork substrates because they are incredibly flexible with a secure and stable basecoat reinforcement layer to eliminate the risk of cracking.
