dual-proof-pre-applied-membraneA new durable watertight solution for below ground structures. A pre-applied membrane that protects against groundwater ingress as well as gases and chemicals.

DualProof is a fully and permanently bonded, composite sheet. It is applied before the steel reinforcement is fixed and the concrete poured. It consists of a sealed two layer highly flexible PVC membrane laminated with a non-woven PP-fleece. DualProof is pre-applied and is installed without heat or open-flame, overlapped and sealed with butyl tape and special adhesive for detailing. The new PP FiberTex Technology gives the DualProof its unique bond and connection to the concrete. The PP-Fleece integrates into the concrete when poured giving a strong mechanical bond once cured.

eurocell-imageAfter a rigorous testing programme, the BBA has given its backing to the market-leading Modus system of PVC-U doors and windows by Eurocell – the UK’s leading manufacturer, distributor and recycler of window, door, conservatory and roofline products.

The BBA considered key product features, including: thermal performance, weathertightness, ventilation, resistance to intrusion, access and durability. Its tests concluded that the PVC-U profiles would function satisfactorily for more than 35 years and confirmed a U-value across the Modus ranges of 1.2W/m²K using 4/20/4mm sealed double-glazed units.

bp-index-sept-eurocell-modus-bba-2The BBA Agrément Certificate covers Modus Single Leaf and Double Leaf Door System, glazed in white, cream or woodgrain finishes, for use in replacement and new-build applications, for external use as primary and secondary access doors in walls of domestic and non-domestic buildings.

bp-index-sept-eurocell-eden-girls-school-modus-case-study-3It also certified the Modus Fully Reversible System, plus the Outward Opening and Tilt and Turn Systems, in white, cream or woodgrain finish, for use in replacement and new-build applications in dwellings, light commercial premises or similar habitable applications.

The effective thermal performance is due to the system’s 75mm six-chamber profile which enables the range to achieve a U-value as low as 0.7 when installed with krypton gas-filled triple-glazed units. Modus has also become one of the very first systems to achieve the BRFC Window Energy Rating (WER) of A++. This is only awarded to windows with an energy index value equal to or greater than +20; and Modus A++ designs achieve this for casement, reversible and tilt and turn windows.

bp-index-sept-eurocell-modus-bba-1Consisting of 50% post-consumer recycled PVC-U as standard, the Modus range of doors and windows demonstrates sustainable use of materials and a smaller carbon footprint than products made or recycled outside of the UK. Eurocell optimises material usage by employing its dual material extrusion technology (DMET) that layers post-consumer recycled and ‘virgin’ material simultaneously, so the recycled material is concentrated in the central core of the profiles where it cannot be seen once the door or window is installed.

bp-index-sept-eurocell-eden-girls-school-modus-case-study-2Coming with a 12-year guarantee (white profiles only), the Modus system is available in nine solid and woodgrain-effect colours, all of which are available with white internal finishes to create a light and airy living environment. A further range of more than 25 solid and woodgrain effect finishes is available to special order, including colour both sides.

system-162-from-hewiTo cut a round tube and rejoin it mitred at right angles – this was the idea of the architect Robert Mallet-Stevens (1886 – 1945), whose lever handle is today known as the “Frankfurter Model”.
HEWI has derived a universal system on the basis of the simple yet clever design. Linear, functional, without superfluous details: System 162 convinces in the sanitary room through its clear design. Matching hardware, signs and handrails made of stainless steel are available.

The minimalist design concept of System 162 not only has a convincing reduced design and a high degree of functionality, but also persuasive quality to match.

The System 162 sanitary products are available in stainless steel or with a high-quality chrome finish. The accessories can be combined with inserts made of satin-finish glass or high-quality polyamide in signal white, pure white, jet black or anthracite grey.

System 162 is augmented with a rail with shower head holder and shower basket. The support rail provides additional comfort and convenience.

REHAU CURTAIN WALLING TAKES ON ALUMINIUM – AND WINS

pr2124-rehau-polytec-50-passivhaus-cross-sectionREHAU Polytec 50 is an innovative aluminium clad curtain walling system designed to compete head on with aluminium offering improved strength and better thermal efficiency, without any compromise on slim sight lines or colour options.

The system was designed and developed by global polymer giant REHAU and has a high strength steel core which outperforms aluminium under load, an aluminium exterior face with slim 50mm profiles which can be powder coated in any colour, and a comfortable, ‘warm to the touch’ PVC interior.

It is also a traditional ‘Stick’ curtain walling system which uses the same profile for both transoms and mullions, making it easy to fabricate and easy to install with minimal wastage.

pr2124-per-fit-windows-has-completed-the-largest-scale-installation-yet-in-the-uk-of-rehau-polytec-50-at-bangor-universityREHAU Polytec 50 has been Passivhaus certified and boasts a Ucw value of 0.8 W/m²K, so it is popular for use in public and private sector commercial projects, and in both new build and refurbished homes where the emphasis is on energy efficiency.

It has also recently been tested and certified to the CWCT standard test methods for building envelopes so can be used in new build developments where an NHBC certificate is required.

Recent installations at the newly opened St Marys student village at Bangor University, North Wales and in the Greenlaw Court apartment building in Ealing illustrate many of its strengths.

At St Mary’s village, for example, 23 REHAU Polytec 50 screens coloured anthracite grey on the exterior and white on the interior were installed at heights of up to 11.3m in new student halls of residence built by Vinci Construction. REHAU’s system was preferred to aluminium primarily because it was more cost effective with no compromise on the aesthetics of the finished buildings, and also because of its better thermal performance and warmer internal face.
Similarly, at the high profile, eight storey 1960s Greenlaw Court, a 20m high curtain walling section in REHAU Polytec 50 was chosen to match the aesthetics of the steel section which it replaced and give the building’s residents better thermal performance with minimal requirements for maintenance.

REHAU has a UK network of fully trained fabricators and installers for the Polytec 50 curtain walling system, including commercial specialists Campbell Mason who have just begun a major project to install Polytec 50 curtain walling in new student accommodation being built at Coventry University.

REHAU Polytec 50 is on display in the REHAU Hub in the Building Centre, London; and further information for architects and specifiers, including full technical specification, is available in a 16 page brochure which can be downloaded from the REHAU website via www.rehau.uk

As part of REHAU’s extensive support package for commercial specifiers which is branded ‘REHAU KNOWHAU’, the company also offers a RIBA approved CPD on high performance curtain walling.

This examines the different curtain walling options – ladder, stick, unitised and structural glazing and explains the differences between them and the most appropriate applications for each.

It also covers the key design criteria – from material, spans and fixings to finishes, glazing and ventilation; and there is a detailed focus on the load considerations which apply when calculating curtain walling designs.

Zehnder’s new Zmart Flex Radiator provides the Solution to Corrosion

zehnder_zmart_600-1000_ral9016_office_udo_003_boeCorrosion in radiators is an all-too common problem, causing many commercial premises to suffer from under-performing heating and then the disruption and expense of maintenance and repairs. Now, however, Zehnder has come up with a solution by introducing radiator components formed from polymers instead of metal. Unlike conventional, pressed steel radiators, the new Zehnder Zmart Flex distributes warmth via a polymer heating register and comprises a network of plastic tubes behind an aluminium front casing. This first-of-a-kind technology heralds a new era of lighter and longer-lasting radiators.

This is the biggest innovation in radiator design since bulky cast iron radiators were replaced by sleeker pressed steel models in the early 1970s, but the plumbing and heating industry has already been using polymer components, of course, for more than three decades. In pipes, pipe elbows, compression fittings, and connectors, polymers have proven capable of distributing hot water perfectly well. And now Zehnder’s research and development has proven that the hard-wearing polymer polybutane works just as well inside a radiator.

zehnder-zmart-radiator_polymer-registerPolymer components became popular in plumbing, in comparison with the traditional copper alternative, because they are easier to install and maintain, less prone to pitting and lime-scale, totally resistant to corrosion, and more durable. Those same advantages are true when polymer is used instead of steel for the heating register inside a radiator. Even when installed within a system with poor water quality, the performance is not impaired.

As well as being unrivalled in its corrosion-resistance, the Zmart Flex is 60% lighter than steel alternatives, which means it can be more easily transported and lifted, and can be positioned and installed by a single person. With the added advantage of patented 360⁰ flexible flow and return tubes that connect to any valve arrangement and give the freedom to fit wherever there’s pipework, the Zmart has been shown to consistently reduce installation times by 30%.

Cycle storage is essential for every school. With a myriad of options available, which one is right for your site? To help you decide, here is a breakdown of the main types of cycle storage and their individual benefits.

The Sheffield Cycle stand is a common sight around the UK and offers a scalable and flexible cycle parking solution. Providing the cycle stands are installed correctly (minimum 800mm apart) each stand will provide secure storage for two bicycles. This style is preferred by cyclists as its simple design allows both the bicycle frame and wheel to be locked to the stand.

Type B Cycle Rack 1 (300x275)Cycle racks are better suited for the smaller, or tighter, site. Cycle racks, such as the AUTOPA Type B, offer a higher density of cycle parking than single level cycle parking solutions. The Type B cycle rack alternates high and low cycle holders, reducing the space between the bicycles to 305mm.

Cycle holders are ideal for smaller sites as they affix to the wall of an existing building without the need for additional space. Cyclists push their bicycle into the holder, and they are secured through the front wheel with the owner’s own lock

In order to satisfy BREEAM regulations, any cycle storage provided must be protected from the elements. This is easily achieved through the installation of a cycle shelter or compound; which are designed to protect bicycles from the worst of the weather. AUTOPA offers BREEAM compliant cycle shelters and compounds in a variety of different designs to match your site’s environment.

AUTOPA Limited has been manufacturing cycle storage and parking control products for over 60 years. The majority of our products are manufactured at our works in Rugby. We provide our customers with a comprehensive end-to-end service; from manufacture through to installation. To find out more, please visit our website www.autopa.co.uk.

Kee Safety, a global supplier of fall protection equipment and safety railing systems, has launched Kee Gate, a range of self-closing safety gates, which provides industrial workers with a safety solution when working at height and on ground level.

kee-gate-1Designed to work both internally and externally, on ladder and stair access points, roof hatches, walkways and roof tops, Kee Gate, ensures maintenance, inspection and warehouse staff can fulfil their job, follow best practices and comply with current safety standards, without putting their safety at risk. Kee Gates are spring loaded so can automatically close behind the user, providing an added level of security and overcoming the potential for human error. This type of system is the preferred solution to chains, bars or sliding tubes, as these traditional forms of protection can lead to a hazardous void, when used incorrectly.
kee-gate2-1Kee Safety self-closing safety gates are available in galvanised steel and if required can be powder coated in safety yellow. The safety gate is available with standard ‘U’ bolts for fixing to uprights of 33.7, 42.4 and 48.3 mm diameter, enabling the gate to be fixed quickly to existing supporting structures, posts or stringers. An additional fixing pack is provided which allows the gate to be fixed to square, flat or angle uprights. Easy to install on all types of handrails or to retro-fit existing structures, such as galvanised handrails and roof edge protection systems, Kee Gate is 1 metre wide. Designed to be trimmed on-site, this solution saves companies the time and money it takes to fabricate their own gates.

Kee Gate is compliant with the requirements of EN 13374 Class A, EN ISO 14122 Part 3 & Part 4 and is CE marked to EN 1090. The range is also compliant with international standards, meeting OSHA, O.B.C and I.B.C requirements. The system has undergone extensive testing to ensure total reliability of the gates. These include salt spray testing to ASTM B117-11 Neutral solutions over 200 hours to assess the coating’s corrosion resistance, life cycle testing to BS 6375-2:2009 Clause 6.5 – Opening and closing of Gate through 90 degrees 50,000 cycles and Abuse Testing where 9 x 25kg weights were suspended from the gate to test what happens if pressure is applied. This ensures durability, superior corrosion resistance and defence against signs of wear.
