DuPont™ Tyvek® FireCurb™ advanced breather membranes fitted in the world’s first two-storey, open source WikiHouse

Forward-thinking construction techniques require pioneering solutions. That’s why DuPont™ Tyvek® FireCurb™ Housewrap – an innovative breather membrane designed with both safety and sustainability in mind – was chosen for an exciting collaborative project. Built to coincide with the London Design Festival 2014, WikiHouse4.0 became the world’s first open source two-storey house, the basics of which can be accessed and assembled within days – for under £50,000.

The installation, led by Arup, The Building Centre and 00 design, was intended to raise awareness about housing issues and the potential application and intervention of ingenious new solutions. Designs will be free to download and can be adapted before being ‘digitally’ manufactured.

Alastair Parvin, WikiHouse 4.0 co-designer at 00 design studio says, “We are trying to spark people’s imagination as to how technology can now enable almost anyone to afford their own custom-built house without the need for conventional construction. We don’t believe that WikiHouse is the only solution to the current housing crisis, but we do want to host a disruptive debate and to challenge landowners, urban planners and policy makers to think differently about the barriers – such as land or building costs.”

The WikiHouse 4.0 frame is a modular construction system made from SmartPly OSB boards that have been CNC machined into numbered parts. It is assembled with wedge and peg connections rather than bolts and with the final panels held into place using ordinary screws. The 70 square metre structure beautifully demonstrates how a simple, easily assembled wooden frame becomes air-tight, waterproof and secure.

DuPont Building Innovations was keen to support the project with an appropriate membrane solution, fitted behind the fibre cement board façade to seal the timber ‘chassis’ and protect the structure from fire, climate and interstitial condensation. The main part of the build was undertaken in six days – and the DuPont™ Tyvek® FireCurb™ membrane was easily and correctly installed in under 3 hours, with prior technical advice from DuPont and clear instruction guidelines.

DuPont™ Tyvek® FireCurb™ is a key development that adds superior flame retardant performance to the highly valued properties of the renowned breather membrane – such as reliable long-term weather protection, effective vapour diffusion and greater energy efficiency. Using innovative technology to reduce the flammability of polymer based substrates, DuPont™ Tyvek® FireCurb™ potentially limits or stops the spread of fire through the external envelope.

DuPont™ Tyvek® FireCurb™

Rather than use halogens, the technology employs a phosphorous containing agent that forms a ‘char’ layer at the surface when it is in contact with an ignition source. This thin layer of carbonized polymer is highly flame retardant and forms a barrier, slowing the release of flammable materials. Starved of fuel, the flame spreads over the membrane more slowly or not at all – and if the membrane does ultimately catch fire, it produces less smoke – another vital advantage for human safety. Rigorously tested, DuPont™ Tyvek® FireCurb™ Housewrap has a fire rating of class B-s1,d0 according to EN13501-1.

Energy-efficiency was also crucial to the WikiHouse 4.0 concept, thus a weather-tight seal that would enhance both thermal performance and interior comfort was the optimal system – qualities embodied in DuPont™ Tyvek® membranes and tapes, which are offered in range of formats to suit every type of build. Durability is also a key consideration for the project, for even though it can be assembled very quickly, a WikiHouse is intended to last.

Nina Tabink, Arup, Senior Structural Engineer commented, “A digital world is emerging where people can connect with anyone around the globe through a simple click. Arup believes in the potential of digital fabrication and open source technology and how this will provide an alternative collaborative way of working, bringing increased efficiencies. WikiHouse has proven to be a perfect partner to explore these new technologies.”

DuPont™ Tyvek® FireCurb™

Jenny Watt, PR & Marketing Manager, The Building Centre said “WikiHouse 4.0 opens up the potential of digital technology to change how we might design, make and construct buildings. The added value of building technology such as DuPont™ Tyvek® FireCurb™ breather membranes was most welcome to the project.”

Sanctuary Housing installs Aico smoke alarms in new development

Sanctuary Housing, one of the largest social housing providers in the country, has installed Aico’s 160RC series mains-powered RadioLINK alarm systems into all of the 96 flats in its latest £10.4 million development in Newlands Place, Cumbernauld.

Sanctuary Housing manages homes across England and Scotland, providing general rented, sheltered and home ownership accommodation. Sanctuary Cumbernauld, one of its regional operations in Scotland, is in the midst of a £70 million regeneration programme to remove the town’s 12 high rises and rehouse the tenants. The new development in Newlands Place, which features four blocks of 24 two-bedroom flats, will rehome 96 families in modern, comfortable homes.

As a key safety measure the development is being fitted with Aico’s 160RC series mains powered, rechargeable lithium battery back-up smoke alarms. David Robertson, Director at FLN Consulting Engineers, specified the alarms for this new development: “We have specified Aico on all our projects for a number of years having been impressed with the overall quality and reliability of the product.”

Each flat has its own stand-alone system. Additional alarms have been installed in the communal hallways, which are interlinked using Aico’s RadioLINK technology to those in the individual flats. An alarm activated in the communal area will cause the alarms in all flats to be activated for maximum safety. Alarms in flats, however, will not cause the communal alarms to activate, thus avoiding issues of alarms causing unnecessary disruption to other residents.

RadioLINK lets you interconnect Aico alarms and accessories together using Radio Frequency (RF) signals rather than cabling. New properties, such as the Newlands Place development, are seeing the benefits of wire free alarm interconnection as it provides far greater flexibility in alarm installation and adaptation.

Aico’s mains-powered 160RC series smoke and heat alarms are a popular choice for specifiers and social housing providers as they contain tamper proof rechargeable lithium back-up cells, which last the life of the alarm. These can provide over six months back-up in the event of a mains power failure and the batteries can’t be removed by tenants for use in other household devices.

A wholly-owned subsidiary of Ei Electronics, Aico is a market leader in residential fire protection in the UK. All alarms are designed and built in Europe specifically to meet the UK standards and regulations. For more information, please go to www.aico.co.uk.

Rinnai + renewables = boosted efficiencies on hot water

Chris Goggin of Rinnai UK, manufacturer of market leading Infinity HE gas fired continuous flow water heaters, believes there is a responsibility for the industry to monitor and control energy usage but warns that prevaricating until the perfect solution is developed is not helping to push things forward.

“It is time to focus on what we can do to decarbonise the UK building stock to support energy and emission target reductions by using the best available technologies today and not waiting for a ‘magic box’ solution tomorrow.”

He says there is no one, single method to achieve energy efficiencies and advocates using a mix of existing renewables and traditional technologies tied in with smart control systems as the practical way forward to a greener future. He urges the industry to act now considering multiple solutions and not one size fits all.

“Experts have warned that energy blackouts are forecast by 2017, so a smart and well engineered method of dealing with the increasing pressures on the Energy Network without over engineering and over pricing is to find ways of using current renewables technology, be it solar thermal, solar PV or heat pump, in a practical manner maximised by traditional fuel sources” says Goggin.

Rinnai award winning renewables water heating solutions are designed to offer a perfect blend of eco-friendly technologies, guaranteed to provide a constant flow of hot water, no matter how many outlets are in use at the same time. The HE Rinnai condensing continuous flow water heater can be utilised as a secondary heat source for a solar or ASHP-boosted hot water delivery system and is one of the most energy efficient. Smart internal and external controls ensures that the Rinnai system is only using the optimum amount of gas, harnessing and maximising renewable gains and not acting as a constant or wasteful secondary heat source.

For all-year round hot water, Rinnai Infinity HDC1500 and HDC 1200 gas fired condensing continuous flow water heaters are renewables-ready or easily ‘retrofitable’ with current renewable technology.

Rinnai’s Infinity condensing products incorporate two heat exchangers to achieve optimum water heating generated from every cubic metre of Natural Gas or LPG, producing efficiencies of 95-97 per cent, easily surpassing the 90-92 per cent thermal efficiency thresholds set by the new legislation in the new build arena. They are extremely low NoX, less than 50mg, with hot water supply volumes of up to 740 litres per hour at 50° Delta from a single appliance. The addition of smart controls to the commercial condensing range cuts emissions further and aid frugality in gas consumption.

Rinnai’s award-winning renewable water heating solutions are designed to offer a perfect blend of eco-friendly technologies, guaranteed to provide a constant flow of hot water 365 days of the year.

Quality Driven by Remmers

Established in 2004 and formally known as Blackhorse Car Sales, Lex Autolease Car Select in Oldbury has over 500 cars displayed in their showroom. The 2000㎡ showroom space along with the 600㎡ workshop space required a high gloss smooth finish flooring to upgrade the executive used car sales operation.

The existing old liquid polymer screed floor surfaces were badly cracked and damaged and needed refreshing and upgrading to better withstand the frequent and abrasive movements of the cars.

Capeland Industrial Flooring took on the challenge, which involved repairing, levelling and finishing the existing flooring with a slightly flexible floor topping that complemented the high end motor car sales. Remmers Epoxyflex PH SL was chosen for its ability to provide additional protection from reflective cracking. Three different shades of grey were employed throughout the buildings for demarcation and to highlight safe pedestrian routes.

The works were completed within a stringent timescale and budget much to the clients satisfaction.

Striking new single ply school roof makes its mark

Oughterard National School is a new single-storey primary school situated in the Connemara district of west Ireland. The architectural vision for this new building, which boasts 16 state-of-the art classrooms, was to create a modern and aesthetically pleasing learning environment that would add real value to the local community. Another priority to the design team was using sustainable technologies and construction techniques to help reduce the building’s environmental impact.

The school building consists of eight roof areas on a variety of different pitches totalling over 3,400㎡ in all. Aesthetics were important to the client as most of the roof areas are pitched at a 20° slope making them highly visible, particularly from the central courtyard area. Bauder’s Thermofol single ply membrane was specified for the new roof because it is lightweight, long lasting, and visually appealing – with welded roof profiles incorporated to give the appearance of a standing seam metal roof. The system build-up also included Bauder’s 120mm Thermotech Glass Insulation for superior thermal performance, ensuring the roof achieved the required 0.19 U-Value.

Due to the visibility of the roof, all aspects of the job were under high scrutiny. The roof profiles had to be lined up perfectly along all the hips and valleys of the roof, requiring a high degree of skill and workmanship from approved contractor Noel Deane Roofing & Cladding, which they well and truly delivered on much to the delight of project specifier Martin Keaveney of JJ Rhatigan who stated, “Bauder were able to provide all the roofing materials needed, which enabled them to deliver a comprehensive solution and guarantee. They satisfied all delivery commitments and the new single ply roof looks and performs just as we expected.”

Since opening in September 2013 this contemporary school building has been recognised for its innovative design and architectural excellence by many award-giving bodies, including being shortlisted for the Best Educational Building at the RIAI 2014 Irish Architecture Awards. The school has also been commended for its environmental efforts, an example of this being how they collect and store rainwater in a reclamation tank so that it can be reused throughout the building.
