  • Terraco Group and Wetherby Building Systems Ltd, both market leaders in the EIFS industry – one in manufacture and the other in distribution - are pleased to work in partnership in the EIFS / EWI market in the United Kingdom. They have come together to offer a wide range of insulated render systems - polymer modified cement renders, silicone decorative finishes, as well as mineral based finishing renders and brick slip systems.

    Building on a combined EIFS / EWI experience of over 60 years, Terraco and Wetherby are developing an unrivalled range of innovative EIFS systems and external finishes. They offer the perfect solution for projects using either traditional or modern construction methods. These exterior insulation finishing systems are suitable for residential, educational, commercial and industrial applications in both the new build and refurbishment sectors.

    It is not just end clients that benefit from our support, our partnerships with our contractors, installers and suppliers are equally as important.

    Our product range consists of fully BBA certified system that includes carry / fixing systems alongside various insulation types. Standard details are available on request and specially created details can be drawn up to suit the project at short notice. All of our EIFS / EWI systems are installed by approved sub-contractors whom we monitor frequently to ensure that the quality of workmanship is being maintained.  We also appreciate some customers will have their own preferred sub-contractors and we are happy to provide training and work alongside them.

    Many local authorities, housing associations and private landlords have realised the positive environmental influence and energy saving external wall insulation has to offer, especially when faced with necessary renovations to social housing developments to bring these homes in line with thermal levels that are enforced by Building Regulations.

    Changes in Government legislation such as Part L of the Building Regulations, The Code for Sustainable Homes and more the introduction of Governmental Initiatives have significantly increased the demand for truly efficient insulation systems which demand more innovative solutions for both new build and refurbishment of residential, commercial and public buildings.

    We understand the complex nature of SWI projects and offer much more than supply of an insulated render system; we can assist with tenders, planning permission, funding, accreditations and warranties, tenant consultations and community engagement programmes.

    More and more architects are realising the potential of Wetherby Insulated Render Systems and are choosing them as a cost-effective, environmentally sustainable method of new build development.

    The BBA approved Terraco Wetherby External Wall Insulation Systems include a range of insulants with the following finishes; Silicone, Acrylic, Mineral and Mineral Render PLUS.
