IKO Polymeric refurbishes NHDC Office

IKO Polymeric refurbishes NHDC Office

IKO PLC

NHDC Office in Letchworth Garden City was an old courtyard style building with buildings on 4 sides covered with a metal roofing system laid to a low pitch and suffering from water ingress. The project involved a major refurbishment of a 1970s office block to enable council services to be brought in from scattered locations in to single occupancy. The main roof areas and glazing were the two major failing elements of the old building.The client proposed an over-roof solution by installing an 18 mm ply secured through the existing metal deck back to the secondary roof structure and suggested using single ply membrane for the waterproofing layer. Working closely with Delomac Roofing, the correct options were discussed and priced and the IKO Armourplan PSG roofing membrane was specified thanks to its flexibility and extended guarantee offer.Replacement of the existing metal standing seam roof system meant that the new alternatives had to reflect the same appearance to keep the original look of the building. The building survey highlighted a woodwool slab base and suggested that any works would require a removal of the base to allow a secure roofing system.The head of the glazed facades was originally detailed with a failing metal mansard dressing and had slipped off allowing major water ingress into the building.Working closely as part of Willmott Dixon’s Supply Chain Network, Delomac Roofing and IKO Polymeric carried out a more detailed appraisal to review the initial specification, and were able to offer an overlay specification, securing the plywood overlay to the woodwool – obviating further building exposure and potential waste to landfill.Whilst the main area was simply detailed, perimeter and mansard details were a lot more complex as they involved cleaning cradle plinths, creating multiple service penetrations and ensuring a crisp building line is maintained on the external facades.IKO Polymeric Armourplan PSG membrane and colour matching standing seams were installed to a very good standard on mansard details.IKO Armourplan PSG is a membrane unique to IKO Polymeric. With its superior reinforcement and the use of premium quality PVC throughout, the membrane’s unique formulation provides ease of installation. The extra flexibility of the membrane helped the installers of Delomac Roofing to achieve the desired tight and crisp details on the standing seams. Pipe details were also installed to the highest standard by using IKO Armourplan G detailing membrane.Potential waste to landfill was dramatically reduced by retaining existing deck and using the woodwool as contributor to the required thermal upgrade. All works were completed to a tight programme schedule despite a particularly wet summer.IKO Polymeric supplied the whole roofing system for this refurbishment project including VCL, thermal insulation, single ply membrane, membrane and insulation adhesives, fixings and fasteners and also rainwater outlets which provided the client a single point guarantee of 25 years.
IKO Roofs Overseas Students at the University of York

IKO Roofs Overseas Students at the University of York

IKO PLC

The University of York has invested in a £27m infrastructure in the Heslington East Campus which is planned as a state-of-the-art learning facility for pre-university overseas students to provide academic preparation programmes prior to their undergraduate and postgraduate studies.The new development – Piazza Building – will provide a 350-seat auditorium, flexible learning spaces including two laboratories, a learning resource centre, a 350-seat lakeside view restaurant, offices spread across 70,000 sq ft. and space for student societies and activities.The new three-storey building was designed as crescent-shaped to wrap around a retained oak tree in the courtyard, located to the south of Langwith College on the University campus.To give the building an aesthetically pleasing and sharp look, aluminium was used on the façade cladding, roof edges and fascia. IKO Polymeric’s Armourplan P PVC roofing membrane in slate grey was specified to complement the dark grey colour of the cladding and roof edges. Chemplas, who managed the roof installation, chose IKO Armourplan P membrane to meet the guarantee requirements of the client and contribute to the BREEAM rating of the building.The crescent shape roof required attention to details and a neat installation which was achieved to a high standard by Chemplas. IKO Armourplan P membrane made the installation easier thanks to its flexibility. Whilst suitable for extended guarantees, this membrane is still only 1.2mm thick, making the complex detailing easier. With high-quality polymer throughout – even on the lower layers – and high-performance reinforcement, IKO Armourplan P membrane offers a robust solution.Due to the campus being exposed to strong winds, a wind uplift calculation was the key to the performance of the single-ply roof. IKO Polymeric’s technical team provided Chemplas with a report advising the right number and type of fixings required in different areas of the roof.Looking over the green fields of Heslington, the roof is now complete and the building will be ready to welcome students from all over the world in the next term.

IKO Permaphalt - Act of Faith

SIG Design & Technology

When Westminster Cathedral’s roof was first asphalted back in 1903, it would have utilised naturally occurring asphalt deposits dug up from an overseas lake. These days, things are done a little differently. Instead, IKO’s Permaphalt – a polymer modified mastic asphalt – was specified for the extensive reroofing of the Cathedral by Architect, Michael Drury from St Ann’s Gate Architects. “Asphalt had worked well for the Cathedral in the past and there was no reason why it shouldn’t again,” he said, adding the new roofing’s 25 year guarantee clinched the decision for a like-for-like replacement.

IKO worked with Brindley Asphalt on this school. The school has 900 pupils, works include replacing the defective waterproof covering, incorporating new tapered insulation to current building regulations and creating falls to remove the drainage of the surface water. Also, replacement of windows and M&E plant to the kitchen area.This was a highly complicated insulation design due to the deflection and backfalls within the existing roof. The roof had several different interfaces such as adjoining roof level, rooflight and specialist M&E equipment.COMPLEXITY AND WORKMANSHIPThere were many changes in elevation and some very neat workmanship was observed, the largest Insulation board was over 350mm deep. In most areas, tapered insulation schemes were designed to alter points/elevations of drainage run-off due to existing issues of ground-level flooding experienced by the site.THE EXCEPTIONAL ACHIEVEMENTS ON COMPLETION OF THIS PROJECT WEREMajor proportion of the work was carried out during the 2020/21 winter months.Impacts of Covid 19Removal of all surface water from a complex roof.The school remained in full operation and the key access point was via the central/core courtyard which involved critical management throughout the contract to ensure both the health and physical safety of pupils could be maintainedCritical programme to our works as access route was to be lost due to new-build extension start date already having been agreed immediately abutting our roof areasAssociated demolition of plant room and isolation of services was also undertaken
