Royal Russell School

The Royal Russell School in Croydon demonstrates the vast variety of waterproofing applications with which DANOPOL membranes can be specified. From standard flat roof areas to pitched standing seam roofs, vertical applications and accessible terraces, the flexibility of specification is really showcased on this project. The most noticeable feature is the stunning standing seam roofs, which are also DANOPOL HSF+ membrane, completed with ALPHA PROFILES. These ALPHA PROFILES are raised PVC profiles made from DANOPOL materials which can be retrospectively heat welded to the surface of the completed waterproofing system. The use of Alpha Profiles is rapidly increasing as the design may be highly customised and the installed centres can be changed to suit a clients particular aesthetic preferences and are often installed to obscure any standard membrane overlaps. An advantage of selecting DANOPOL membranes over a traditional metal standing seam roof option is that at less than 3.00kg per m2 for the waterproofing membrane, the system is incredibly lightweight and may be installed onto many lightweight structural substrates. The reduced load, when compared to traditional standing seam roof options, can also translate into savings on the underlying supporting structure. Our DANOPOL+ HSF membrane was also utilised on the terrace areas, which included vertical detailing to clad the internal faces of the parapet walls, providing a fully-encompassing watertight finish to the roof areas.
