Zink CLADDING & SHEETING 01992 801927 www.almhm.co.uk Powerlon FlameOutTM is a new house wrap breather membrane that is flame retardant to Class B for all timber wall installations. FlameOut has been developed by Industrial Textiles & Plastics (ITP), industry leaders in flame retardant technology, and joins the Powerlon range of technologically advanced building and roofing membranes. The new building membrane is strong but lightweight, with high water vapour permeability, and is the only product to be independently certified to EN ISO 11925-2 as Class B-s1,d0 for use in all timber frame constructions with no installation restrictions. A self-extinguishing FR material, FlameOut is available in two roll sizes: 1.5 x 50m and 3 x 50m, providing installation advantages for builders. It will be particularly valuable for use in safety critical buildings, both residential and commercial. Marc van der Voort, managing director of ITP, said: “Our 25-year expertise in developing flame retardant products for the construction industry went into the creation Powerlon FlameOut. “We’re proud to offer this new product which will increase building safety for our customers in the UK and abroad.” Other Powerlon flame retardant Opening the way for Kalwall 052 DECEMBER 2017 RCIMAG.COM building membranes from ITP include Powerlon UV Colour FR, which is flame retardant to Class 0/Euroclass B. This UV-resistant façade membrane has been specified for a number of projects, including RIBA-award-winning The Word in South Shields, the Glasgow School of Art and the Canada Water Library, another RIBA-awardwinning public building. The breather membrane comes in a range of attractive colours and is designed for use behind open or closed ventilated rainscreens and façades. The ITP technical team is available for site-specific installation advice and offers a concise technical briefing on flame retardant standards and testing procedures for building membranes. In addition to a large range of roof and building membranes, ITP also produces the Powerclad range of weather protection and containment sheeting and the Powerbase range of ground and gas barrier membranes, hydrocarbon and VOC barriers. www.itpltd.com Powerlon flame retardant membranes Copper Stainless New Powerlon FlameOut house wrap is flame retardant to B1-s1,d0 RIBA-award-winning The Word protected by Powerlon UV Colour FR New VCL offers higher protection The A. Proctor Group has launched a new high-performance variable resistance vapour control layer. Procheck Adapt is designed to protect the building fabric from the potential risks of condensation whilst providing the added benefit of serving as an effective airtight barrier. The new membrane offers variable resistance which adapts to changes in humidity levels, becoming increasingly more resistant in winter and more permeable in summer. This ensures that the building fabric is protected from damaging moisture levels during cold, wet winter months, and allows the fabric to dry out effectively in warmer, drier months. Procheck Adapt has a translucent structure which eases fixing to structural frames and, in combination with its integral tape, allows for a fast installation time. It has long been recognised that the correct management of moisture vapour within buildings is important in ensuring the longevity of the building fabric and the health of the occupants. Management of moisture at the design stage is critical. The introduction of Procheck Adapt will ensure that it provides a high level of protection throughout the building’s lifespan. www.proctorgroup.com Structura UK says it has formed a strategic partnership with RAICO Bautechnik GmbH to develop an adaptation of its THERM+ curtain walling system to accommodate Kalwall. The THERM+ framing system conceals fixings and screws making for a seamless finish and the flexibility to use a frame in aluminium, timber or steel. It also presents the opportunity for semiunitising the panels which can incorporate windows, Kalwall or a combination of both. This allows for monolithic, single action installations which save time on site and give excellent cost benefits together with a high-performance long lifecycle. It has passed a series of assessments designed to replicate various CWCT (Centre for Window and Cladding Technology) criteria and EN 13830 “Curtain walling – Product standard”. Testing was completed using the RAICO THERM+ 56 A-I system with a standard Kalwall 70mm panel. It is anticipated that one of the first installations to use this solution could be the Japanese Moshimo Skylight Restaurant in Brighton. The new system makes this daring and innovative project viable and will make use of the versatile stick frame by using steel, aluminium and timber backed curtain wall. Steve Rogers, sales manager at RAICO UK, commented: “Between ourselves, Structura and Kalwall we have modified our frames to create a fantastic system offering huge versatility and scope. We’re delighted the initial rounds of inhouse testing have proved so successful and are already looking at using this system on a raft of new projects both in the UK, across Europe and in the USA.” www.kalwall.com Japanese Moshimo Skylight Restaurant, suspended several storeys above Bartholomew Square in Brighton
