Sto products were used to achieve the required thermal performance and 0.2 W/m2K U-value for the new Ronald McDonald House, at a 1,000-bed Hospital in Wales.

“The Ronald McDonald House provides free ‘home away from home’ accommodation for families who have children being treated at the hospital, so comfort was an important factor in its design and construction,” explains Alex Southall of AEW Architects.

“There were a number of reasons behind our specification of the Sto products, not least of which was the fact that Sto are the market leader in this area. Ronald McDonald House Charities typically operates this type of building on a very long-term basis, and so we needed a high-quality insulation solution which would provide the required level of insulation performance, and also prove to be durable and long lasting. The practice has used Sto products successfully on previous projects and so Sto was an obvious choice for this one.”

The BBA-certified StoTherm Classic K system combines insulation board and entirely cement-free rendering components. This offers a market-leading impact resistance of 60 joules, which is up to 10 times greater than a similar cementitious system. It was applied to the Ronald McDonald House using Sto-Turbofix, a single-component adhesive foam that allowed for fast and easy installation. It was finished with StoArmat Classic cement-free reinforcing render, and a top coat of StoLotusan.

StoLotusan is the only render available that uses a Lotus-Effect® technology which provides unbeatable water and dirt repellence. It forms a unique surface texture that causes the rainwater to run off the render quickly and easily, removing any dirt or debris as it goes. In the case of the Ronald McDonald House this will provide outstanding resistance against the growth of algae and fungus, and ensure that the building retains its looks for many years to come.

“Like AEW we have also used Sto products on a number of previous projects, so we knew they would perform on this new building,” explains Adam Caswell of the Joyner Group who installed the insulation. “The actual installation process was relatively fast and straightforward, exactly as we expected, and the finished result looks excellent.”

There are 14 Ronald McDonald Houses across the UK, which last year helped keep over 8,000 families together, close to their seriously ill children in hospitals far from home.
