Project Detail
Ger Y Lan is a private property located in a rural part of Carmarthenshire, subject to the harshest Welsh climate. After struggling for years with problems of cold, damp conditions in their home because of poor-quality, aged rendering, this homeowner decided to seek support from local builder, T.A.D. Builders to find a cost-effective solution to resolve the issues and improve the energy efficiency of their home.
The state of the existing render was very poor – old, cracked, and with issues of water ingress. This home needed the best EWI solution to resolve these urgent problems. T.A.D. Builders immediately arranged a consultation meeting with long-standing collaborative EWI partner, Sika, to jointly survey the house and propose the best solution to the client.
Sika’s high-quality EWI system using 90mm of EPS Grey with dash finish was the perfect solution for the property, offering much needed weather protection as well as highly effective thermal insulation. The challenge for T.A.D. Builders and Sika was to ensure that the product was installed correctly, making sure that the existing damaged render was well prepared and sealed so that the new EWI system worked as effectively as possible. The use of Sika’s market leading sealants as part of the EWI system package was beneficial to ensure that the installation was water-tight and weatherproof. The Sika technical support team worked closely with T.A.D. Builders, being on-hand via phone and regular site visits to monitor the installation and ensure it was delivered to the highest quality.
The installation of this product has been life changing for this homeowner. The reduction in energy costs is significant, meaning that the stress and anxiety of paying the energy bills has reduced and the home is now a comfortable place to live without the issues of damp and mould. Not to mention the fact that the property now stands beautifully on its plot, boosting the homeowner’s feeling of joy and pride to live in such a splendid place. The reduction in U-value from 1.66W/m²K to 0.30W/m²K is evidence of the significant results that this EWI has delivered.
This project is a great example of collaboration between the contractor, T.A.D. Builders and Sika to deliver the best EWI solution possible to improve this family’s financial costs, home comfort and general well-being.
