Latest innovations and products in the building fabric section of the construction industry.

Buildingspecifier offers an insight into the service and fixings solutions offered by EJOT UK Ltd., the Leeds based specialist.

The Met office may be regretting deciding to individually name every new weather front that approaches the UK – at the current rate Storm Zebra should be with us before Easter – though it does underline the frequency with which high winds and driving rain affect the country. Which is why specifiers require the technical support and general savvy of a company like EJOT UK.

Those attending the recent RCI show at Coventry’s Ricoh Arena will have witnessed the diversity of fixing solutions for flat roofing, rainscreen systems and other construction challenges offered under this global brand; but the products are really only part of a holistic, service based technical offering.

We are all familiar with the map detailing the different exposure conditions to which structures are subjected, but it requires real expertise to translate wind speeds into the right fixing patterns and types. Crucially the EJOT range encompasses different options for mechanical and chemical anchors to suit all the common exterior substrates: including plywood, metal sheeting, brick or blockwork masonry and cracked or uncracked concrete.

By engaging with EJOT, contractors and consultants can access the company’s testing capabilities which will confirm the suitability of certain solutions to the location, the height or configuration of the building and the material which a rainscreen system or built –up roofing system is being secured into.

Brian Mack Technical Business Development Manager for EJOT UK Ltd  said “Globally EJOT is expanding its product offering relating to concrete, brick and block substrates: by consolidating our existing brands, through research & development, and from consultation with OEM’s and engineers. We have the products within the range to meet all installation issues into the different substrates, to tackle a wide variety of applications and performance criteria.”

A further example of the latter would be the Trio ‘general application’ anchor for insulation materials, which is aimed at sub-contractors tasked, say, with securing insulation as part of a rainscreen installation. Described by Brian Mack as versatile and reliable as well as being very cost effective, Trio comprises two types of fixing pin, both of which combine with the same high quality sleeve.

Meanwhile, the three Trio components can be used to fix into concrete or clay bricks including perforated types and aircrete blockwork. The 10mm diameter sleeve itself is manufactured from high density polyethylene to create a variable anchor zone, from 30 to 60 mm depth. The glass-reinforced nylon pin is intended to be used for securing lighter weight insulation such as expanded polystyrene back into brickwork or concrete. Then the metal pin will normally be used for heavier insulation types, though still being suitable for lighter EPS material. EJOT Trio then presents a generic, non-system specific product solution.

Also prominent amongst the products showcased on EJOT’s stand at RCI the company was introducing its new HTK-75-2G 75 mm diameter tube-washer, for part-adhered flat roofing installations.

Importantly it meets SPRA guidelines for bonded/mechanical hybrid installations and is suitable for securing insulation back into either ply or profiled steel decks.

EJOT’s technical sales engineers will advise on the correct fixing centres in relation to wind-load calculations, while the tube-washer and threaded fastener not only address cold-bridging concerns, but the telescopic design provides resistance to imposed loads. With the insulation and membrane permanently secured using EJOT’s hybrid solution, the job is completed by folding and heat welding the laps.

With such a comprehensive collection of fixing products to choose from, and technical resources including site testing available to back them up, potential customers need to investigate the EJOT offering fully.

Grade II* Listed Chapter House is a striking building sitting adjacent to the iconic St Paul’s Cathedral, it was designed by Christopher Wren and his son and built between 1712-1714.

The building was originally used as accommodation for the Dean and other members of the Chapter. However, after suffering severe damage during the Second World War it was refurbished in the 1950s into offices, and has since been viewed as the administrative heart of the Cathedral.

Recently Chapter House underwent a major revamp to bring it up to modern and ecological office standards. A key requirement was to improve the thermal insulation throughout the building, retaining the buildings heat and reducing energy bills.

As a specialist in the design, manufacture and installation of secondary glazing, Selectaglaze was specified as its tested products can reduce heat loss by up to 50%. This can be achieved by the bespoke fitting of the secondary glazing alongside the use of high performance seals.

A number of Selectaglaze slime line products were used to suit the various window styles and sizes. These units were mainly chosen as the units are discreet, and a reversible adaptation and are accepted by heritage agencies across the UK.

Over 120 units have been installed in six different colour finishes to match the existing frames.

Established in 1966 and Royal Warrant holders since 2004, Selectaglaze has a wealth of experience working in all building types, as well as an extensive range of products to suit all projects.

Although modern renovation plasters are a superb alternative to tradional types; don’t overlook the possibilities impervious coverings – along with hybrid and insulated plasterboards. So says Hudson Lambert, director of Safeguard Europe.

Impervious coverings come in a few varieties, yet easily the most popular are meshed cavity drainage membranes. These are attached to walls using special fixing plugs, and then can be plastered over using traditional gypsum, lime or other plasters. Effective as they are, it should be remembered that despite a notional air gap behind the membrane, these systems are not breathable and will drive rising damp further up the wall unless controlled at source using a high specification remedial damp-proofing cream or rod.

More recently, fleeced DPMs are a natural development from meshed cavity drainage membranes. First, a flexible waterproof adhesive is applied to wall, then the fleeced DPM applied over adhesive and, finally, traditional plasters can be applied on top.

These have the same disadvantages as meshed cavity drainage membranes; yet are faster to apply and their lower profile makes it easier to blend them in with existing plaster finishes.

Beyond these two types of membrane are new systems based around ‘hybrid’ plasterboard. The design intention of these is to utilise the convenience of plasterboard, yet enhance it to reliably allow its on walls susceptible to damp. This is especially useful in situations where speed is important (e.g. tenanted properties where decanting may be inconvenient) and decoration can take place as soon as the system is installed (when using dry joints rather than a plaster skim).

Although they are not suitable where wall surfaces are particularly uneven, they are Breathable (except where foil-backed or insulated plasterboard is used) and BBA approved types are available – which acts as reassurance to clients such as local authorities.

Installation is relatively straightforward: water-repellent/salt-disrupting silane cream is applied to wall and plasterboard applied in the traditional way (although water/salt resistant MS-polymer adhesive is used instead of traditional gypsum-based plasterboard adhesive). ‘Synergistic’ chemistry ensures a high strength chemical bond between the silane cream and the MS-polymer adhesive (due to covalent bonding between the silane components of both materials).

While a plaster skim is usually applied over the plasterboard, using a ‘dry jointing’ method allows the fastest results – and means walls can be re-plastered and re-decorated in less than 24 hours.

If required, the system can be used in conjunction with insulated plasterboard. However, as is always the case when using internal wall insulation, certain precautions are required to minimise condensation risk and it will hinder drying out of the wall compared with when standard (porous) plasterboard is used.

A new landmark headquarters building in West London has been created using Crittall windows to reflect its historical context and satisfy conservation requirements.

184 Shepherd’s Bush Road is a striking redevelopment of a Grade II listed garage and showroom originally constructed for the Ford Motor Company. Erected in 1915-16 the building was designed by Manchester-based architect Charles Heathcote who drew on contemporary American practice utilising what was then a pioneering engineering solution to structural framework. The resulting reinforced concrete frame and modular plan of the three-storey structure influenced strongly architects Collado Collins in their design for the new building.

The character of the building’s broad frontage has been retained – an important consideration because of its listing and its location in a conservation area – with Crittall large form Berkeley windows providing a significant visual aspect in the street scene. The Berkeley was originally created in order to replace existing 1920s and 1930s steel windows that were predominantly single pane leaded glass, exterior putty glazed. With the Berkeley, Crittall developed an entirely new series of hot rolled sections where a solid steel chamfer replicates exterior putty glazing, whilst the interior glazing improves access for reglazing and security.

Berkeley offers an ideal solution for both replacement projects and new construction where minimum sightlines, maximum daylight, and fine detail are desired. The system is suitable for high-end residential, institutional and, as in the case of Shepherd’s Bush Road, commercial applications.

In complete contrast with the traditional frontage, the redevelopment – which was completed in June – has added three further storey’s beneath a glass dome completely enclosing the roof.

Roy Collado, Partner of ColladoCollins, said: “This is an exciting reimagining of an important local landmark. The designs sympathetically maintain the industrial heritage of the building and the surrounding area, whilst proposing a sleek and contemporary aesthetic… The use of innovative techniques to inform and influence the design is something that we believe could really enhance the site.”

In order to meet the requirements of the project Crittall Windows tackled a number of challenges associated with the physical size and weight of the Berkeley units specified. So as to optimize capacity to deal with the quantity required by the contract the company utilized a newly installed piece of equipment – its 4 axis CNC Machining Centre – which ensured that consistently accurate machined components could be produced with short lead times assisting the flow of the product so as to meet the stringent on-time needs of the installation programme.

The 115,000 sq ft office building has now been occupied by customer science company Dunnhumby as its European headquarters.

A dynamic guide for flexible, acoustic canopies and baffles has been published by Armstrong.

Expert advice on the almost endless range of dramatic design and acoustic possibilities that can be achieved with canopies and baffles, including Optima Baffles Curves, the first curved mineral baffles in the industry, is contained within a new floating ceilings brochure from Armstrong.

Floating ceilings inspire great spaces by introducing new shapes and add depth, scale and rhythm to internal areas, creating a contemporary aesthetic for modern building designers in the transport, education, commercial and retail sectors.

But the 56-page A4 guide also explains that canopies and baffles can help create a more sustainable interior, contributing to improved indoor air quality and acoustics, and supporting high-mass, low-energy construction.

All this in a peerless variety of colours, effects including wood, and materials including mineral and metal, as well as shapes including square, rectangular, circular, concave, convex and curved. Floating ceilings are also ideal for the easy integration of building services such as lighting and cooling and heating elements.

Floating ceilings are capable of providing greater acoustic sound absorption than continuous ones because all their faces and edges are exposed, and because they are easily relocatable are as suitable for retrofit and refurbishment as they are for new-build.

In addition, specially-engineered surfaces reflect up to 87% of light to improve illumination, making spaces brighter and more comfortable and cutting energy bills. They are additionally sustainable in that they are manufactured from a high degree of recycled material and are also recyclable.

The brochure also explains how product variety is backed by service support including consultations with specifiers or main contractors, supply of BIM and production of CAD drawings bespoke to the project which are then used to engineer a production schedule and logistics plan, and on-site guidance and post-installation review if required.

Armstrong’s new floating ceilings brochure is available to download here and via the Armstrong Ceiling Systems App available from both the Apple store as well as the Google Play store.

A striking suburban home by Bosske Architects, which is wrapped entirely in Marley Eternit Acme Red Smooth clay roof tiles, has received a prestigious Australian Think Brick design award.

Now in its ninth year, the Think Brick Awards celebrates design excellence in the use of clay brick, concrete masonry and roof tiles by Australia’s best architects and designers. This year’s awards attracted 315 entries with Camino House, a suburban extension project in Western Australia, winning the Roof Tile Excellence award for its innovative use of clay plain tiles as a singular material across the whole building envelope.

Camino House was designed in the manner of an ‘oast’ or hop kiln, with the new part of the building mimicking the chimney forms of the surrounding housing, reflecting the suburb’s history, yet at the same time creating a striking aesthetic. UK-manufactured Acme Red Smooth single camber clay plain tiles were chosen by the project’s architects, Bosske, as a natural product that could be used on the facade, as well as the roof, to create a unifying sense to the form.

Each year the trade association Think Brick Australia runs the awards, in partnership with the Concrete Masonry Association of Australia and the Roofing Tile Association of Australia, to encourage architects, designers and builders to rethink brick, concrete masonry and roof tiles as contemporary and sustainable design materials. The Roof Tile Excellence Award, with a prize of AUD$10,000, is sponsored by the Roofing Tile Association of Australia.

Ms Elizabeth McIntyre, CEO of the Roofing Tile Association of Australia and Think Brick Australia, was one of the judges on the panel.

“The judges chose Camino House as one of the winners this year because it opened their eyes to the incredible design opportunities available through use of roof tiles. The roof structure on Camino House, clad in the beautiful smooth red roof tiles from Marley Eternit, is a striking design that showcases how roof tiles can move from traditional to contemporary application not only on the roof but also on the façade,” said Ms McIntyre.

The project involved the roofing contractors, Carter Roofing & Slating Pty Ltd, working closely with the architect and builder in order to achieve the numerous tile junctions on the continuous clay surface.

Sarah Jackson, marketing product manager from roof tiles’ manufacturer Marley Eternit, comments: “We are delighted that Camino House has been recognised by the Think Brick awards’ judges. The selection of our Acme Red Smooth clay plain tiles as a singular material has created a building which has a sense of permanence and robustness in this raw suburban context and perfectly showcases the versatility of clay plain roof tiles in today’s architecture.”

Marley Eternit’s Acme single camber clay plain tiles are available in a range of eight colours to help match local vernacular and meet planning requirements. The tiles also offer excellent design flexibility, with the ability to be used at pitches as low as 30°, as well as for vertical tiling applications.

The Acme clay plain tile range also boasts impressive environmental credentials, including the ability to achieve an A+ rating in the BRE Green Guide to Specification, BES 6001 Responsible Sourcing accreditation and certified carbon footprint data at product level.

A range of fittings, accessories and ventilation products is also available to complement the tiles. To request a sample or literature please contact 01283 722588 or visit www.marleyeternit.co.uk/clay.
