Sika Trocal delivers five star roofing solution at luxurious Riverbank Hotel extension

Single ply roofing membranes are extremely versatile and ideal for virtually any flat roofing project, offering speed of installation and a huge reduction in costs. At the Park Plaza Riverbank in Central London, the installation of high performance Sika-Trocal Type S and Type SGmA membranes will ensure the hotel’s multi-million pound extension and reconfiguration is completed on time and to the highest standard.

Located on the South Bank of the River Thames, within a short distance of Big Ben and the London Eye, Park Plaza Riverbank welcomes guests from all over the world. As part of a European development programme by parent company PPHE Hotel Group, including three new hotels in London and one in Germany, an eight-storey extension complete by 2016 will add 184 new rooms and a new private penthouse with terraces to the hotel.

Working with ESA architects and Gear Construction, the design has been delivered which includes the creation of eight separate roof areas of different sizes, shapes and pitches. With a fast and reliable installation a key requirement, the mechanically fixed Sika-Trocal S and SGmA systems proved to be the optimum roofing solution, offering a smooth and rapid installation, excellent flexibility and crisp, simple detailing.

Innovation in action

Due to the city centre location, two roof pitches of 25° and 44°, and both the complexity and number of roof sections, a forward-thinking application method was required. With the company’s unique and innovative abseiling solution, ICS Roofing was appointed as the project’s roofing contractor. With the complexity of the design, ICS employed specialist Sika-Trocal installers Brightside Roofing to complete the application over a projected 18 week period.

“After careful planning and co-ordination with Gear, they supplied a cantilevered scaffold off the building which allowed us to abseil equipment as a means of fall arrest and to create safe access to the various roof areas,” said Tom Peach, Contracts Manager at ICS Roofing.

“Many flat roof membranes do not lend themselves to installation using an abseil, due to the double fix method of insulation and membrane. Heat welding can also become an issue when working on steeper pitched areas, however, Sika-Trocal system offered us a speedy installation that saw the first two roofs installed in under two weeks – much quicker than the 25 days predicted.”

Working for ICS throughout the project, Brightside installed a total of 1,755m2 of the Sika-Trocal Type S roofing membrane across the three main roof areas. Using the unique Sika-Trocal Laminated Metal Discs and thermally broken fasteners, this provided a rapid and economic roofing solution by allowing ICS to secure both the membrane and the insulation in one go, reducing the fasteners required by 40-60% and speeding up installation.

As well as being one of the most rapid and economic systems to install, it allowed the installation team to achieve exceptional waterproofing and durability – approved by the British Board of Agrément (BBA) to have a life expectancy, in their opinion, of in excess of 35 years.

Devil is in the detail

The unreinforced nature of Type S membrane offers exceptional malleability and allows high quality detailing works to be completed to an exceptional standard. On the 44° pitched roof, insulation was cleverly installed in a step formation to allow installers safe and easy access to the highest point of the roof – with the membrane allowing a single continuous application towards a stunning box gutter and parapet detail.

For a number of complex details, ICS turned to Sika-Trocal Metal for a neat aesthetic and crisp finish to perimeter flashings and junctions. As well as a stylish aesthetic and a fast application, health and safety of site operatives and members of the public has been a prerequisite from start to finish.

Working closely with Gear Construction, as well as other trades on site from cladding specialists to steelworks contractors, ICS carefully coordinated site deliveries and use of the crane to minimise disruption and risk. With long term performance of the membrane an absolute must for safety both inside and outside of the hotel, ICS also carefully considered wind load calculations prior to the application.

“Due to the complexity of the roofs and with health and safety absolutely paramount, it was imperative that the roofs were correctly designed and secured to resist wind loads, ensuring outstanding performance and longevity,” added Tom Peach.

Sustainable solutions

As part of the overall application, ICS Roofing appointed Eco Green Roofs to complete the installation above 227m2 of Sika-Trocal SGmA membrane. The system was overlaid with sedum matting to create a living roof area and improve the roof’s thermal performance.

The garden roof systems are compatible with all existing membranes and once installed, will extend the life of the green roof, help reduce heating and air-conditioning costs and even water sewage charges. The living roof system consists of everything from traditional sedum mats, drainage layers and edge trims, to security railings and harnesses.

With low environmental impact a key factor on site, ICS utilised a complex array of insulation ranging from flat board and tapered to new ultra-thin vacuum insulation panels (VIPs). Installed on a series of four terraces, 100m2 of the highly innovative new VIPs were used to overcome the common on-site challenge of door threshold heights.

Completed over a four month summer period, but with the wettest August on record, the innovative, fast and high quality application of Type S and SGmA single ply membranes from Sika-Trocal have ensured that Park Plaza Riverbank remains on track for its 2016 completion date. Thanks to careful collaboration between Gear Construction, ICS Roofing and Sika-Trocal, this stunning extension and reconfiguration will soon welcome thousands of new visitors from all over the world to the highest quality accommodation in the heart of London.

A final coating to put others in the shade

The first new building to open in Northampton’s flagship Waterside Enterprise Zone is the £8.5m University of Northampton Innovation Centre, seen as a hub for organisations that deliver social impact. This striking six floor cubic building leaves the onlooker in no doubt that Northampton’s new development means business.

Locally based Powdertech Corby Ltd powder coated the solar shading system on the exterior of the building, a contract worth £11K.

Richard Besant, Powdertech Corby Sales Director commented “We coated over 1800 individual sections comprising fins, end plates and brackets, in a premium quality Valspar architectural powder, RAL 9010 white matt. When we viewed the completed building at the end of the job, we could appreciate the fabulous visual effect these solar shades create, in addition to being part of a highly functional design.”

Vertical solar shading fins on the north, east and west side of the building will shade the windows from summer sun and moderate solar gain. They improve the insulation value of glass in the winter by acting as a windbreak. On the south side of the building, horizontal solar shading fins, across the windows, will reduce glare and solar heat gain in the summer but also allow low winter sunlight to shine through in the colder darker months.

Architectural powder coatings are especially suited for use on solar shading systems. The powders have excellent gloss retention, resistance to corrosion and UV light and will last for up to 40 years without significant colour change.

The Waterside Enterprise Zone is part of the Northampton Alive regeneration scheme and incorporates a new £330m campus for the city’s University alongside global brands and thriving small businesses.

Coastal Hotel & Spa stops false alarms with Nittan

Nittan’s Evolution EV-DP Dual Wavelength Photoelectric smoke detectors have been installed into The Cliff Hotel & Spa in Cardigan, West Wales by Fire and Security Alarms Ltd. (FAS) Carmarthen.

The Cliff Hotel & Spa is a large family-owned hotel featuring 70 en-suite bedrooms, spa and gym facilities, function suite and a golf course. As part of a hotel wide refurbishment project, the existing fire alarm system has been removed and replaced with a sophisticated Nittan Evolution system featuring 260 Nittan devices, including over 200 EV-DP smoke detectors. The system runs on four loops controlled by an Advanced Electronics control panel.

Nittan Dual Wavelength Photoelectric smoke detectors were selected by installer Fire and Security Alarms Ltd. (FAS) to prevent further issues of false alarms that the hotel had been experiencing previously. The primary cause of these had been steam escaping from the en-suite bathrooms and activating the smoke alarms.

As an NSI Gold, BAFE and NICEIC approved contractor, Fire and Security Alarms Ltd. (FAS) provides both design, installation and maintenance of fire and security systems primarily in West Wales. It has a diverse customer base including nursing and residential homes, factories, shops, schools, social and domestic housing. It has built its business on the of quality of its services, providing effective fire and security solutions to customer’s requirements, including The Cliff Hotel where it identified Evolution EV-DP smoke detectors as an ideal solution to the false alarm issue.

Nittan Evolution EV-DP smoke detectors have been designed to reduce false alarms caused by non-combustion products such as steam, dust and aerosols. Unlike other industry standard (single optical sensor) smoke detectors on the market that claim to distinguish between smoke and non-combustion products, the EV-DP effectively measures the actual particle size in the chamber via its combined IR and blue LED technology. As steam and dust are much larger particles than smoke, the detector won’t false alarm.

Nittan EV-DP alarms are not just highly resistant to false alarms, but come with a number of key features and benefits, including their use of a sophisticated and highly flexible Sine Wave FSK protocol for data transfer to and from the panel. This protocol also allows for substantial amounts of information to be transmitted back to the panel at very high speeds. Furthermore, they come with a 360 degree OMNIVIEW LED indicator, permitting clear and visible indication of the sensor’s operation from any angle. Increased EMC immunity is also achieved by the inclusion of a “Bandpass Discriminator Circuit” which is built into every sensor head and loop device.

The Nittan Group has been at the forefront of the international fire protection industry since 1954 and has sales, R&D and manufacturing bases in four countries, including the UK. The company continuously innovates and strives for exceptional quality products that meet the highest of standards.

Energy savings for Bristol family with EWI by Saint-Gobain Weber

weber.therm XM External Wall Insulation ( EWI) has been installed on a two-storey end of terrace, privately owned property in the Brislington area of Bristol. This is just one of several upgrades being undertaken by the homeowner which have included the addition of a large extension to the side of the property; a loft conversion; the addition of a garden room to the rear and new windows and doors throughout.

“We bought this 1960s property knowing that a substantial makeover was needed and being in the construction business I could see the potential and have managed a lot of the work myself,” says Mark Holden, property owner. “The property was unattractive, even ugly, with hard to treat solid walls, and it was cold. We wanted a more attractive home and greater comfort for our young family.”

The application of BBA accredited and Energy Saving Trust listed weber.therm XM EWI was carried out by M P Plastering Limited, Somerset, renowned for excellent render application skills and experienced with use of the weber.therm EWI systems. The couple sought Green Deal funding with the help of M P Plastering, a Green Deal certified applicator, and successfully achieved a 75% contribution toward the £9,000 cost of the EWI project.

“The Green Deal funding was surprisingly easy to achieve,” says Mark Pickthall, M P Plastering, “which is just as well considering how cold the house was and that there was a young family to keep warm. The property looks completely different now with the application of Weber’s EWI system. We like everything about Weber from start to finish. Great representation, excellent technical support, industry-leading warranties and products that are consistently reliable.”

The weber.therm XM EWI system used on this property included 90mm thick expanded polystyrene (EPS) insulation which was mechanically fixed to the outer skin of the wall substrate. The render process requires two passes of weber.rend LAC, a cementitious render into which the fibreglass reinforcement meshcloth is embedded to give a robust render coat. When dry the surface is primed with weber PR310 in preparation for a 1.5mm thin coat decorative finish of weber.plast TF, an acrylic based, pre-mixed, textured finish, in Winter White. The porch has been finished in weber.pral M one-coat, through-coloured monocouche render in Chalk. weber.therm XM EWI is capable of substantially improving the U-value of a property in a retrofit project, and produces exceptional levels of energy efficiency on new builds.

“Where I had made additions and re-modelled the internal space the external walls were in an awful state. And from an aesthetics angle, it was great to cover the whole exterior with EWI. We can no longer see the scars and joints,” continues Mark. “Work started at the coldest time of year in November 2014, but within weeks we were feeling the benefit of the EWI. During a particularly cold spell we found there was no need to switch the heating back on after the timer programme had lapsed each morning which would have been necessary previously.” By February the property was fully wrapped and rendered.

“The massive visual improvement to our home is quite amazing,” says Mark, “but the saving we have made on our monthly fuel outlay is incredible. From an average of £150 per month during the winter months we are now paying around £80 a month, that’s a very big saving for a family.”

“We have carried out many projects on this property and my wife and I agree the EWI application has been by far the most successful element of our plans.”

Weber products are manufactured from carefully selected raw materials at purpose-built facilities in Bedfordshire, Shropshire and Ireland where quality and consistency is achieved.

Rinnai space heater excels in energy efficiencies

The Rinnai range of Energysaver fanned convection powered flue gas fired space heaters offers the highest efficiencies on the market.

The range has been designed specifically for use in schools, community centres, libraries, conservatories and churches and other large enclosed spaces where they offer exceptionally high efficiencies in operation and contribute to drastically reduced running costs.

The Energysaver 1004T has an input of 11.6kW and outputs 10.23kW. Its measurements are 670mm x 930mm x 315mm and it has energy efficiencies of 96% under the guidance of Part L 2014. This puts it in the top rank of space heaters in its class.

It provides safe, controllable heat with maximum energy efficiency, combined with flexibility of location.

The heater is also suitable for central timer control. This feature allows the building manager to run any number of Rinnai space heaters off a central time clock providing heat to the large of spaces. The Energysaver Multi controller is not limited to single Energysavers as the flexibility of the system guarantees units can be mixed and matched to satisfy even the most unique of buildings.

The units are encased in a low surface temperature (LST) casing to avoid any risk of burns and offer easy on/off operation and intelligent features such as self-diagnostics and a self-learning pre-heat time to maximise heat up time and energy consumption. Warm air is delivered at floor level for greater comfort and coverage of even greater spaces.

Rinnai Energysaver units are very easy to install as there is no need for expensive (and extensive) ductwork, nor do they involve to running heating circuits for radiators or pipework to boilers. This cuts down drastically on cost and time at the point of installation.

The Rinnai Energysaver 1004T delivers energy-efficient and consistent warm air powered by Natural Gas and LPG options via fully modulating burners so heat and energy input is significantly reduced as the space warms up.

“Rinnai energy saver space heaters really do deliver a cost saving on installation, low operational costs and maintenance, lower life cycle costs, lower replacement costs, high energy efficiencies. They are infinitely suitable for refurbishment projects and, due to Rinnai’s confidence in the superiority of its engineering processes, they come with a 15-year warranty on the heat exchanger,” explains Chris Goggin, Associate Director of Rinnai UK.

The Rinnai Energysaver range comprises fanned convection-powered flue models that exceed seasonal thermal heating guidance under Building Regs Part L, while also heating the usable space within buildings, ensuring comfort, efficiency and compliance.

New commercial chemicals optimise system performance

Fernox has launched an enhanced range of commercial chemical water treatments, which includes: FC1 Inhibitor, FC3 Cleaner and FC1 Filter Fluid+ Inhibitor. Specifically designed for larger commercial systems, the three new products provide contractors with the high quality and reliable solutions needed to maintain energy efficient heating systems and protect vital system components from breakdown and failure.

Featured within the range is the universal, powerful FC3 Cleaner. Its formulation has been designed to purge commercial systems from harmful sludge and debris and restore the efficiency of existing systems. The effective product is also ideal as a pre-commission cleaner for new installations and suitable for use when conventionally flushing.

Once the system water is clean, the best-in-class FC1 Inhibitor should be utilised to protect against limescale build-up and corrosion formation. The FC1 Inhibitor is a proven formulation that is left within the system to maintain system efficiency and extend component longevity.

In cases where conventional flushing is difficult, not practical or even where high pressure powerflushing could create further system problems, then the unique FC1 Filter Fluid+ Inhibitor is recommended. The product combines the proven effectiveness of F1 inhibitor with an active dispersant package to detect, lift and deliver contaminants to a system filter.

For example when used together, FC1 Filter Fluid + Inhibitor and the TF1 Delta Filter will continuously protect against circulating debris that could cause system damage or breakdown – working to restore system efficiency. This complete solution mitigates the need for a system shutdown.

Also featured within the commercial chemical range is the popular Alphi-11 Antifreeze Protector. With proven capabilities and a reliable performance, the product is both non-toxic and compatible with metals and materials commonly used in heating systems. Alphi-11 can be left in the system all year to prevent frost damage and freezing pipework to temperatures down to -22 ̊C. Additionally, the combined antifreeze and inhibitor package avoids the need for a winter drain down and prolongs system life.

“Commercial heating systems are vulnerable to the build-up of sludge, scale and corrosion, all of which not only has a detrimental effect on system performance and carbon emissions but also affect the longevity of the system,” said Francine Wickham, Global Marketing Director at Fernox. “Our complete range of chemical water treatment and filter technology allows contractors to maximise the energy efficiency of commercial systems and protect vital and expensive system components from premature breakdown.”

FC1 Inhibitor, FC3 Cleaner and FC1 Filter Fluid+ Inhibitor are available in 20 litre packs and Alphi-11 Antifreeze Protector is available in a 25 litre pack.
