At the forefront of industry research and development, RCM constantly strive to innovate and develop their range of building boards and facades. Finding the latest technology is an ethos which lies at the very heart of RCM business and one that separates them from their competition. With a comprehensive range for all applications – RCM recognise the importance of providing quality certified products which have been rigorously tested, to meet the demands of a challenging construction industry.
Ian Quinton, Managing Director of RCM – suppliers of building boards, facade and roofing solutions to some of the UK’s most prestigious developments, outlines the key criteria to consider when specifying building boards and cladding solutions for structural applications.
Quality Certified Products
RCM recognise the importance of providing quality certified products which have been rigorously tested, to meet the demands of a challenging construction industry.
In order to select the right product for the right application, specifiers need to be supplied with the right technical information. The NBS National BIM Report 2014 reveals that 90% of specifiers find product inclusion in NBS BIM useful – they of course would say this, however as one of the few building board suppliers to use this specification system – RCM are great advocates.
Specifying systems with a credible certification provides reassurance and confidence to specifiers. BBA, for example, offers full technical approval for construction products and is recognised by building control, government departments, architects, local authorities, specifiers and building insurers – essential in developing school buildings. BBA Approval provides architects, designers and contractors with certified information when specifying or installing building board products.
Structural Strength and Stability
A significant consideration when assessing building boards is to ensure the optimum racking performance to enhance structural strength. For example, European Norm – BS EN 594:2011 is the recognised testing protocol for testing racking strength and stiffness of timber frame wall panels.
Another factor to consider for stability is moisture movement. When evaluating a solution, consider a system that offers a high level of dimensional stability with limited moisture movement. Building boards can be specified with as little as 0.06% moisture movement. By specifying a building board that is fully tested to BS EN 1062-1, it ensures the boards have adequate moisture resistance and durability and will have a life equal to that of the building.
Behaviour in Relation to Fire
The Building Regulations for England and Wales set out the legal obligations for building designers. These functional requirements outline what must be done, but do not address how to achieve this. An example of a functional requirement that covers structural stability in a fire is that, ‘the building shall be designed and constructed so that, in the event of a fire, its stability will be maintained for a reasonable period.’
RCM make technical information readily available and the material safety data sheet for building boards and external cladding systems is a good starting point.
CE Marking is a manufacturer’s declaration that the product meets the requirements of the applicable EC directives in terms of safety, health and environmental requirements. CE Marked buildings boards appear under the harmonised standard of BS EN 12467:2012.
NEW to RCM’s products portfolio for 2016 – Tilcor and DAFA ranges.
The stone coated and satin-finished roof systems incorporates cutting-edge Zincalume protective steel, which gives the tiles longevity and service life over traditional galvanised tiles – delivering a visually appealing finish and long term durability. The Tilcor range of pressed metal roofing tiles includes five distinctive profiles
A wide range of products for creating airtight building envelopes, including: breathable membranes EPDM Weather Resistant Seals and Vapour Control Layer (VCL) Tape ranges.
Both these products will be launched at the RCI Show 2016 on the 27 & 28th January 2016, Ricoh Arena Coventry – stand E9.
