One episode which aired earlier this summer followed the ambitious plans of Murray Rees to restore an elegant Victorian townhouse on the northside of Dublin City. Murray opted to use Diasen Diathonite Evolution cork lime thermal plaster from Ecological Building Systems, along with Pro Clima airtightness products and Thermafleece sheep’s wool natural insulation in his attic.

The primary benefit of using Diathonite Evolution is that both levelling and insulating a wall can be executed in one action. This can be crucial in renovating single leaf stone or brick walls with internal or external plaster. Up to 30mm of Diathonite cork lime plaster may be applied over two to three days which allows for significant savings in project turnaround.

Ecological Building Systems’ Niall Crosson (group technical manager) commented: “On Murray’s project just 30mm of Diathonite Evolution lime thermal plaster reduced the U-value from 1.79W/m2K to 0.81W/ m2K, and the system was applied over the course of a week, at a similar cost to conventional natural hydraulic lime plasters.

“Whereas a conventional NHL plaster would require at least a month to dry and attain a U-value of only 1.67W/m2K at the equivalent thickness. This project was the perfect example to illustrate the economic and technical benefits of utilising lime-based breathable thermal plasters.”
