Some of our most important public sector assets are held within the healthcare system so choosing the correct specification is critical. Often these buildings host patients or the latest medical equipment, and this centrally funded NHS project at Chase Farm Hospital was no different. This particular project hosted an array of plant and equipment for the NHS and our lightweight DANOPOL HS 1.5mm mechanically fastened membrane was chosen as the waterproofing system to be installed onto the structural metal deck. The scheme also featured a tapered insulation scheme in partnership with Kingspan Insulation designed to 1:60 falls and 0.30 w/m2 K u-value. When installed to structural metal decks, all the mechanically fastened components are mechanically fastened to the crowns only, so careful consideration must be made to ensure that any mechanical fasteners coincide appropriately. A project-specific wind uplift calculation was completed by our technical team which provided detailed instructions and fastening patterns for the mechanical attachment of both the waterproofing membrane and tapered insulation scheme. In addition to ensuring that the system will resist any applicable windload, our calculations can reduce overall frequency of fasteners, ensuring that the project is not over-engineered and ensure that the installation progresses as quickly as possible.Waterproofing Systems:DANOPOL HS 1.5mm - Light GreyConstruction Type:New BuildWarm RoofSector: Public Sector Approx.

When developing new buildings, it is always important to consider the environmental impact. Responsible sourcing of materials is high on every priority list, along with reducing waste to landfill. But what about the local impact, such as the effects on local wildlife? A living roof/green roof system, such as the one installed by the Premier Contractor at Seaford Head Golf Club, is a very clear example of the steps that can be taken towards reducing this impact and providing an alternative space for wildlife to inhabit. A warm roof system was installed onto a structural plywood deck, after which a vapour barrier and insulation boards were mechanically fastened to provide both thermal efficiency and air leakage control. After the underlying installation had been suitably restrained in accordance with a site-specific wind uplift calculation, the roof membrane was mechanically fastened to complete the waterproofing system. Our PVC roof membranes have been tested and can be utilised without the need for additional root prevention barriers (test standard EN 13948), and because PVC is extremely lightweight, they are the perfect choice for these applications, reducing pressure on the underlying structure. In conjunction with our Living Roof/Green Roof specialists, a site-specific living roof system was supplied and installed over the completed waterproofing.Waterproofing System:DANOSA Single Ply 1.5mm - AnthraciteConstruction Type:New BuildWarm RoofSector:LeisureApprox.

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. Waterproofing System: DANOPOL+ HSF 1.5mm - Dark GreyConstruction Type: New Build Warm Roof Sector: EducationApprox.
