When used in conjunction with Durisol’s innovative wall form system, Lime Works Ltd traditional lime putty render will shortly be available with a 25-year guarantee. The proven Lime Works Ltd render system provides the perfect complement to Durisol in both structural and ‘green’ performance. Durisol enables fast-track construction of interior and exterior walls using dry-stacked interlocking blocks manufactured from at least 80% Forest Stewardship Council (FSC) recycled waste softwood, bonded with a proprietary cement/PFA (Pulverised Fuel Ash) mix.

Lime Works Ltd was established in 1998 to address the growing market for traditional lime putty render that meets the performance demands of the modern world. The company prides itself on producing genuine English lime putty mixes at a reasonable cost, which can be applied at speeds that compete with modern alternatives. Harry Cursham, Managing Director of Lime Works Ltd, says: “All our products are offered with a standard 10-year guarantee, but we believe they’re good for longer. Because of Durisol’s proven building performance and our shared values in sustainable building, we will extend the warranty to 25 years as a major incentive to encourage specifiers and contractors to use Lime Works Ltd and Durisol together to ensure a sustainable and aesthetically pleasing solution for modern building projects at a sensible cost.”

Enabling faster construction times, Durisol interlocking modular units are simply dry-stacked, with no need for mortar or bricklaying skills. The units are then filled with concrete to create solid walls with excellent thermal and sound insulation - more than twice those of conventional walls. The system is available with Rockwool mineral fibre insulation, which offers U-values as low as 0.19 without additional insulation.

John Flower, National Sales Manager for Durisol UK, says the announcement of a proposed 25-year guarantee reflects his company’s confidence in Lime Work Ltd lime putty render. He says: “This is a real advantage for today’s building industry, which is under increasing pressure to get greener within ever tighter budgets. The combination of our two products addresses this challenge, with a fast and eco-friendly solution that answers many of the concerns of planners and conservation officers.”
