Roofing, Cladding & Insulation Focus

s the weather begins to improve and opportunities open up for significant refurbishment – unoccupied school buildings for example – it seems now is an ideal time to consider much-needed improvement to public buildings.

To avoid costly challenges and errors, correct specification from the outset is essential and key to long-term performance. Sourcing from a trusted supplier that can guarantee a full technical support service is also integral to the success of your refurb. However, for buildings that will remain live working environments, a fast and effective solution from an experienced supplier should be your first port of call. PSBJ’s timely Roofing, Cladding & Insulation supplement offers advice on various scenarios, from a live crematorium installation that required a watertight solution throughout continued services, to the over-cladding of a large-scale tower block installation which is now benefitting from increased energy efficiency.

Roofing, Cladding & Insulation Focus calculations, condensation risk analysis, and whole life cost evaluations can also be included upon request. All of this is vital when ensuring you make an informed decision on your choice of roofing system and, if required, insulation upgrade. On top of all the technical considerations, the UK roofing industry also faces many environmental and economic challenges – whether it’s higher costs for raw materials and energy, faster growth in emerging economies leading to greater global competition, or the pressures faced by architects and specifiers to design sustainable buildings. As such it is vital that manufacturers continue to develop innovative solutions that support the industry in its goal to becoming ‘sustainable’. Ideally all manufacturers should invest heavily in in-house research and development teams, which enable them to anticipate and respond to the future’s major challenges – such as energy and resource efficiency, climate change, water scarcity, efficient infrastructure, and air quality. At Sika, the company has invested in Life Cycle Assessment of its roofing systems so that it can demonstrate not only potential cost savings to the customer, but also the green credentials of its products over the life of the membrane. Life Cycle Assessment (LCA) is a standardised method to assess and compare the inputs, outputs and potential environmental impacts of products and

Refurbishing flat roofs condition of the substrate. A photographic record will be made and, where deemed appropriate, investigative methods such as core samples and pull out tests will be used to confirm the condition of the existing roof. A bespoke specification is then produced from the results of the roof survey, including project specific detail drawings, tapered insulation plans and roof layouts (where required), U-value calculations, wind uplift

Following the recent economic downturn and a slowing in the pace of new build projects, refurbishment has become the only solution for many people - offering a more cost effective option to restore and renew rather than build afresh. But refurbishment can be difficult and provides its own set of complex issues, not least when it comes to roof refurbishment.

E

nsuring you choose the right waterproofing solution for your roof is vital, but just as important is the support and knowledge provided by the roofing system manufacturer. Sika Liquid Plastics, Sika Sarnafil and Sika-Trocal all offer a range of roof refurbishment solutions – whether it’s single ply or liquid applied membranes – and decades of technical expertise. Depending which system you choose Sika can also offer a full technical service, bespoke detail drawings and wind uplift calculations, as well as regular inspections by the nationwide team of Field Technicians. Before a project begins a comprehensive roof survey will be conducted to determine which system is most suitable for the project, during which a core sample will be taken to assess the current roof construction and

years”. Sika Liquid Plastics liquid membranes are an outstanding refurbishment solution, allowing an extension to the lifetime of existing roofs. They may simply be applied over the waterproofing layer as they are compatible with most materials and can be recoated at the end of their life expectancy to extend the service life even further. Investing into quality is a smart choice

– it means saving more and for longer; saving costs as well as saving energy and resources due to fewer replacements and less maintenance of the roofing system over time.

services over their life cycle. There are several different impact categories and resource indicators which can be assessed. As a standard approach, Sika evaluates all impact categories and resource indicators deemed as important according to the relevant standards. For roofing, Cumulative Energy Demand (CED), Global Warming Potential (GWP), and Photochemical Ozone Creation Potential (POCP) are considered to be the most relevant. So how can roofing systems contribute to sustainable construction? Sika provides roofing systems that use less energy and resources by comparison with competitive technologies, as well as offering a low Global Warming Potential, which also means a reduced carbon footprint. Upgrading the thermal performance of existing buildings is also an ideal way of saving energy and will help building owners to comply with UK Building Regulations. A thermal upgrade can be easily achieved by installing additional insulation over the existing substrate and completing with a new waterproofing system. By using the existing build-up as a base, benefits can also be gained by:

However the above can only be achieved if a satisfactory comprehensive survey has been completed to determine the condition and suitability of the existing substrate. This is something that Sika takes very seriously and its top end guarantee not only covers its own product, but also the suitability of the existing substrate – something that most manufacturers cannot offer.

Making the right choice The durability of building materials is a key driver for sustainable building construction. External studies have documented the outstanding service life of Sika Liquid Plastics, Sika Sarnafil and Sika-Trocal roofing systems, with the British Board of Agrément certifying some Sarnafil membranes to have a life expectancy that is “in excess of 40

resistance against freezing, wind, hail and sleet. To round off the warm roof system, Paravapo SBS vapour control layer, insulation to current regulations and Adepar JS bituminous underlay were used to provide the waterproof foundation for the shingle layer.

Detailed planning Due to the important service that the crematorium provides, the facility remained open to the public throughout the refurbishment and placed site restrictions on SPV Group who carried out all works during weekends only; it was therefore essential that the site remain watertight at all times. This was achieved through detailed planning and the use of a systematic approach – operatives stripped one section of the roof, laying the new deck and applying

the vapour barrier before moving on the next area. This approach ensured a high quality of finish while remaining courteous and considerate to visitors. Despite the limited timescale of eight weeks and dependency on weather conditions, SPV Group worked intelligently throughout the refurbishment to meet the challenges and the project was completed two weeks early while complying with all relevant health and safety regulations. Speaking of the finished project, Jane Baker, Manager of Telford Crematorium says: “The new roof really is fantastic. We’ve had a number of positive comments from the public, funeral directors and even members of staff on its appearance.”

orven and Grampian Courts, and the sheltered housing scheme Brimmond Court, which were built in 1969/70 in the Balnagask area of the city, had been identified for a thermal upgrade under the city council’s housing capital programme which provides the catalyst to deliver many of the objectives in the housing business plan. Over-cladding the three towers comprising 156 rented and privately-owned flats with external solid wall insulation and a mixture of a total of almost 8000m2 of Steni’s Nature and Colour rainscreen panels was carried out by Highrise Solutions for main contractor Lovell. Some 6865m2 of Steni’s Nature panels were used on the majority of the elevations of the 13-storey blocks. Nature panels feature a surface of aggregated natural stones from Europe and are available in 17 different natural stone colours and up to five grades in many of

these colours. At Balnagask, they were fabricated by panel supplier CEP Architectural Facades, in more than 3000m2 of beige and the fine grade for the east and west elevations and in almost 4000m2 of white in the coarse grade for the south and north elevations of the reinforced concrete structures. The 850m2 of matt lilac Colour panels were then rivet-fixed, like the Nature ones, onto an aluminium rail support system, under new window pods. These panels feature a smooth surface of 100% acrylic that is electron beam cured without the use of solvents. They are available in 60 standard colours and almost any colour from the NCS-, RAL- or BSsystem as well as three gloss levels.

It would ensure that these blocks remain structurally sound for the next 30 years or so, and would, in conjunction with the provision of district heating, reduce the impact of fuel poverty to the residents.” Far from the next 30 years or so, Steni’s Nature and Colour panels are designed to perform for more than 60 years. In fact, Steni recently marked almost 50 years of manufacturing with the launch of a peerless 40-year functional warranty. This has been extended from 25 years on both Nature and Colour panels, which allow a modern, dry-trade approach to cladding, and dwarfs the typical guarantees of 10 to 15 years that are offered on traditional render systems. A council spokesman said: “Grampian, Brimmond and Morven Courts were built in

the early 1970s when electricity was cheap and thermal insulation standards were poor and as the years passed these homes became very expensive to heat. We needed to upgrade them to increase their energy efficiency and help reduce residents’ bills. “The external walls are now three times better at retaining heat than they were prior to the works. We have also extended our award-winning district heating scheme, which is currently the most cost-effective means of heating high-rise blocks, to these courts.” He added: “The Steni panels play an important part in the project by improving the weather tightness of the building fabric and to protect the existing reinforced concrete structure and precast concrete cladding panels from the elements.” Steni panels were also used to over-clad Steni’s Nature and Colour panels are designed to perform for more than 60 years

Channelling patients' ebb and flow Steni’s Colour panels are helping to lighten the mood for patients and visitors to the £40m critical care complex at Ulster Hospital in Dundonald, Belfast. The Colour panels were specified by specialist contractor Hynds Architectural Systems in matt white for the soffits of the state-of-the-art building. The panels are suspended from the main slab and feature illuminated inserts which light up a wraparound overhang at night, casting a soft and reassuring glow over the building’s perimeter. The PRP project for South Eastern Health and Social Care Trust was designed by lead consultants Todd Architects in association with Watkins Gray International and built over three years by main contractor Gilbert Ash. The building extends over four principal floors, with the lower two levels covering much of the footprint of the confined site, and the upper two levels split into two wings divided by a landscaped courtyard that introduces light into the depth of the plan. Externally, the palette of materials established by Todd Architects to direct future development in the hospital is

Designed to increase the number of theatre and recovery beds while improving the flow of patients and staff facilities, the complex also allows for future expansion and the expected increase in demand for services over the next 15 years. The critical care complex, along with new renal and maternity units, a refurbished elderly care unit, main stores and a terraced car park, represent phase A of the £400m, 10-year redevelopment of the 50-year-old Ulster Hospital.

Meeting a cladding challenge The robustness of Steni’s Colour panels has helped meet the architect’s design for the colourful exterior of the redeveloped City School in Sheffield. Some 3000m2 of the Colour panels, in a total of eight shades, has been used on the facade and main entrance soffit of Phases 1 and 2 of the £22m Building Schools for the Future (BSF) project.

The redeveloped school was designed by architects at HLM to be inspiring to all, including the community which has access to its facilities after school hours. Students were involved in looking at key factors in the planning process such as design, sustainability, landscape and technology. Steni’s lightweight panels were installed in long horizontal and vertical bands and in colours ranging from light yellow to dark grey by specialist sub-contractor NG Developments. The rainscreen element used structural adhesive on an aluminium sub-structure and the remainder was made up into Steni-faced composite panels and glazed into a low-rise aluminium glazing system. NG’s Ian Dunn said: “The rainscreen cladding was particularly challenging due to the numerous differing colours and especially the sizes of the panels required for the architect’s scheme. The panels were structurally bonded to the carrier system which was carried out under specific weather conditions and within tight temperature

Welsh school sets the benchmark Architects specified nearly 3000m2 of BENCHMARK Roofliner with a Keybemo Standing Seam finish for the roof

A Welsh school has reached grade A status thanks to advanced insulated panel technology from the BENCHMARK range.

Y

sgol Bro Alun is a new Welsh Medium school in Gwersyllt, near Wrexham. Opened in September 2013 at a cost of £5.9m, the school provides space for 240 children aged between 3 and 11.

Complementary materials The new build is a 2000m2 single storey, steel frame and cladded building with external car parking and play spaces. Architects specified

nearly 3000m2 of BENCHMARK Roofliner with a Keybemo Standing Seam finish for the roof, with 996m2 of BENCHMARK Karrier Engineered System for the walls, to support the facades. A range of facade finishes were chosen to complement the build, including Ceramic Tile (terracotta), Ceramic Granite, Oak Timber and Coloured Glass (green shade). The range of colours, textures and finishes used gives new pupils a smart and

inspiring space to learn. Contractor Harry Fairclough Construction was brought into work on the build. Dave Harry, Commercial Manager at the company comments: “Working directly with BENCHMARK and their approved installer RH Roofing and Cladding, meant all aspects of their team were on hand throughout the course of the works, providing a level of service that mirrored the high quality of the BENCHMARK products supplied and the seamless installation on site. To this end both ourselves and the client are delighted with the final end result and the impact BENCHMARK has had on the building finish overall.”

Unrivalled performance

The plan for the build was dictated by a number of different factors, ranging from educational building standards, through sensitivity to the local area, to compliance with the council’s energy efficiency guidelines. Fraser Brown, Sales Director for BENCHMARK, explains: “BENCHMARK Karrier offers unrivalled thermal and air leakage performance versus the system’s overall thickness. This has contributed to the school’s award of a BREEAM ‘Excellent’ rating, and should reduce its energy bills for years to come, a vital benefit as prices rise. Architects and specifiers can choose BENCHMARK, safe in the knowledge of the superior performance and flexibility it offers.”
