A large residential development in the heart of the beautiful Perthshire
countryside is benefitting from the superior protection of Roofshield, one
of the highest performing roofing membrane solutions, a pitched roof
underlay, which is both air and vapour permeable.
The new building near Murthly, in Perthshire is part of a tailormade timber frame kit design supplied by Scotframe, with the construction managed by specialist contractor Algo, design and build, based in Perth.
To form an integral part of the roof construction, Scotframe selected the Roofshield membrane from the A. Proctor Group to ensure the highest level of protection. Scott Cameron, Project Manager for Algo commented: "The Roofshield membrane has been excellent in terms of its weather tightness, with absolutely no leaks across the whole of the 583m2 site. It's also incredibly robust so we didn't have to worry about tearing or damaging it on site."
Roofshield continues to be one of the highest performing roofing membrane solutions and is the preferred choice of architects, developers and contractors. Many vapour permeable underlays use an airtight VP film layer to achieve their performance. In contrast, Roofshield's patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. It has an extremely high degree of vapour permeability, as well as air permeability, so will still perform in conditions in which airtight alternatives will not.
Preservation and protection is nothing new for this beautiful part of Scotland, which is home to some ancient woodland. Indeed an Ancient Tree Inventory across the region recently identified a sweet chestnut tree as old as Bonnie Prince Charlie, which became the 15,000th ancient tree in Scotland.
