New Ronald McDonald house roof in good health thanks to Sika-Trocal

Ronald McDonald House Charities (RMHC) provides free ‘home away from home’ accommodation for the families of young patients being treated in hospital. For the charity’s new-build facility at South Glasgow Hospital Campus, Sika-Trocal has supplied 600m2 of its single ply membranes as part of a high performance waterproofing system that includes a living roof and a series of projecting window pods.

Designed by architectural practice Keppie on behalf of RMHC, the new building on the South Glasgow Hospitals Campus replaces the Royal Hospital for Sick Children in Yorkhill. Expected to be completed by summer 2015, the new building comprises three white brick traditional forms with slate pitched roofs, with each connected to the other by glazed openings as part of a bright and welcoming aesthetic.

Working with main contractor CCG, McConnell Roofing was appointed to complete the single ply elements of a roofing contract that included an expansive green roof and outwardly projecting window pods. For the main roof area, McConnell Roofing applied 500m2 of Sika-Trocal SGmA as part of a complete green roof system comprising vapour control layer, PIR insulation, Sika-Trocal SGmA waterproof covering, Sika-Trocal SBv protection and separation layer, drainage layer and vegetation.

Quick, lightweight and economical to install, the mechanically fixed SGmA system ensured McConnell completed this crucial project element on time and with minimal impact on other trades on site. Mechanical fastening also allowed McConnell to secure both the membrane and the insulation in one go, reducing costs and time with a strong and safe fixing method.

As part of the overall application, McConnell also installed 100m2 of Type S single ply membrane over a series of window pods. Offering exceptional waterproofing and durability, the cold-applied Type S roofing membrane is also approved by the British Board of Agrément (BBA) to have a life expectancy of up to 35 years.

“We have been installing Sika-Trocal single ply membranes on successful projects for many, many years,” said Ken Wales, General Manager at McConnell Roofing. “With the tight site and a series of intricate detailing works presenting a number of challenges, Sika-Trocal’s single ply membranes once again proved the perfect solution at Ronald McDonald House.”

Completed within a two-month period by a project team of four, the innovative application of both the SGmA and Type S solutions by McConnell Roofing ensured the project remained on track for its summer 2015 completion. With its high quality and reliable roofing solutions, Sika-Trocal will once again help to keep an important building watertight for years to come.
