  • Wienerberger - Using clay pantiles under the new British Standard BS5534
    pantiles actually performed on the roof in terms of both security and weathertightness Now fast forward to present day and consider how we can install clay pantiles in accordance with the new fixing requirements Taking Wienerberger Sandtoft clay pantiles as an example firstly these are manufactured with nail holes that penetrate through the tile nib thus enabling every tile to be nailed into the top of the tile battens Until quite recently though clipping pantiles in the same way that single lap concrete tiles are clipped ie with a clip securing the left hand side of each tile was difficult if not impossible This is because this method of clipping the tile tended to cause it to roll over rather than secure it Therefore special clips have been developed that sit between the mitred corners of a tile and the adjacent tile in the course below and simultaneously hook and secure both tiles at once thus preventing the tendency of the tiles to roll over These clips are very secure and are not visible on the finished roof Although we all know and understand the great benefits of dry fixed ridge and hip systems we must acknowledge that these are not always appropriate for some traditional roofing situations clay pantiling being a good example It is certainly possible to use dry fix systems with clay pantiles but the appearance may not be too pleasing for example because pantiles generally have quite deep and sweeping rolls and pans using a standard dry fix ridge roll means that there are large gaps between the tile pans and the ridge tiles The nature of clay pantile manufacture means that there are small but natural variations in size between tiles making it difficult to produce dry fix systems that accurately fill the spaces between

  • Wienerberger - A trend towards low roof pitches with long rafter lengths
    underlays do not provide complete waterproofing protection where they are penetrated by batten nails etc and may leak if any driven rain or snow passes through the roof tiles BS 5534 the British Standard for slating and tiling gives clear guidance for double lapped slating All recommendations and calculation methods for determining slate lap and pitch are based on a maximum rafter length of 9 metres for areas where the rainfall does not exceed 56 litres per square metre per spell or 6 metres where rainfall is likely to exceed 56 litres per square metre per spell The Standard provides a rainfall map of the United Kingdom that gives predicted categories of driving rain exposure derived from historical weather data BS 5534 does not provide similar information for manufactured roof tiles therefore it is left to the manufacturer to provide appropriate recommendations Each tile manufacturer will provide their own recommendations but as guidance I will set out below what Wienerberger Sandtoft provides for its own tiles and slates Firstly Sandtoft s recommendations for minimum roof pitch headlap and gauge etc are based on ordinary domestic buildings and uses the limitations set out in BS 5534 for slates as detailed above for maximum rafter length Where a roof slope exceeds the recommended maximum rafter length at minimum roof pitch for example on larger homes and commercial buildings then the design of the roof requires special consideration One perhaps obvious option is to increase the roof pitch For guidance Sandtoft recommends that the pitch should be increased by one degree for every half a metre distance that the rafter length is over the recommended maximum length For example for a rafter length of 8 metres in a 6 metre rainfall zone and the minimum recommended roof pitch for the proposed tile is 17 5 degrees then the roof pitch should be increased to at least 21 5 degrees CAD Illustration Box Gutter This particular option of increasing the roof pitch to compensate for a long roof slope could be considered until 30 degrees is reached but above 30 degrees the water run off is such that no further increase in pitch would be of major benefit But remember that increasing the roof pitch also increases the rafter length so this particular option only has limited benefit If it is not possible or practical to increase the roof pitch then alternative ways of dealing with the issue should be considered For example the roof could be divided into shorter sections by the use of a gutter partway down the slope The illustration shows a possible detail for such a gutter This detail is commonly used closed to the eaves to enable the omission of the normal visible gutter but it could also be utilised to reduce long rafter lengths Depending upon the design of the building it may be feasible to have features such as differing roof levels but without draining onto lower level roof slopes dormer windows or Northern lights to break

  • Wienerberger - Exploring what BIM really means for the Construction Industry
    1970s But considering the age of the idea why has it suddenly become so important to the future of the construction industry Well to give an extremely simplistic answer BIM needed the technology to catch up with the idea Even at the point at which the acronym BIM came into use in a 1992 paper the notion of providing a digital representation of the physical and functional characteristics of a facility was not something that seemed within practical reach However it was clearly an idea that had incredible implications for the construction industry of the future and one that would gain serious traction and investment over the coming decades The real beauty of BIM and what makes it so incredibly useful as a design tool is that it is able to go far beyond the two dimensions of a drawing It can augment the three spatial dimensions width height and depth with time and cost meaning that BIM represents not just geometry but conjures a projected reality Obviously from a project planning perspective this is amazingly useful virtually saving money and improving performance before a single brick has been laid Likewise the model of information created can be shared amended and updated from the design team to contractor subcontractor and operator each able to add their own discipline specific data to that shared model without anything being lost or overlooked in the process As a result BIM hugely assists with the drive to reduce UK wastage on government projects and will see an estimated 8 8 billion saved which can be spent on more projects and further improving our infrastructure for the coming population increases we are experiencing on a global level This will be achieved through level 2 BIM by 2016 for all government projects over 5 million Germany and France have just announced that they will require level 2 BIM by 2017 So the UK is once again leading the way in Europe But what about 3D CAD I hear you shout Well in short 3D CAD is not the essential part of BIM in fact you can reach level 1 BIm with 2D CAD but you need 3D modelling to achieve level 2 both require you to follow the process of work outlined in PAS1192 2 2013 The benefits of utilising a 3D CAD system are clear the functions offered by revit and other systems help ease the process of sharing information between peers and sets up the government soft landings requirements very nicely So yes the process of BIM is made much easier through the use of such specialised software PAS1192 2 3 and 4 outline all of the basics of the BIM process and which are so important to the core of the process that they are being moved straight into ISO status leapfrogging BS status completely As the finer details of BIM were developing savvy manufacturers realised that they needed to make sure that they were able to provide all of the key specification

  • Wienerberger - The Appeal of Clay Paving
    and replacing with a new one As a result the overall maintenance and replacement costs are significantly lower than other forms of paving materials very much putting the upfront cost of clay into context The second reason for its comparative scarcity of use in the UK is that clay pavers are not as widely available as for example concrete and stone This is simply because clay requires more skill to work with and so it isn t something that every manufacturer can produce Though this is very much part of its appeal because the UK has such a rich resource of natural clay this is not something that should hold clay paving back it simply needs people to understand its many benefits in order to really become the UK s number one choice To put it simply clay could easily be widely available but it s just a question of demand Blue Diamond Pattern Paver Perhaps the most obvious benefit of clay is how it looks The aesthetic effect of clay is far more appealing than concrete thanks to its warm appearance and far sturdier than asphalt delivering an unmatched richness of colour that lasts an entire lifetime Unlike other material types that use artificial dye or pigment during the manufacturing process clay won t be affected by ultraviolet light and even heavily trafficked or pedestrianised areas and will have no problem with dark colours shininess or reflective light Furthermore that colour will run consistently through the entirety of the product colour through and is an inherent and fundamental property of clay material The surface of clay pavers offers a natural highly abrasive texture that not only adds to the visual appeal of the product but also makes the pavers both slip and skid resistant with the majority of pavers

  • Wienerberger - BS 5534 British Standard Code of Practice
    also gives guidance on restrictions on the use of underlays such as maximum batten gauges and country zonal areas 2 Mortar bedding will no longer be relied on as a fixing Mortar can still be used but it must be supplemented with mechanical fixings such as nails screws or clips etc In practice this means that mortar bedded ridge and hip tiles must all be mechanically fixed 3 Theoretical wind loadings on the roof have increased This means that stronger and more fixings are required to secure the roof tiles and slates In practice it is unlikely that any roof tiles on a roof would not require fixings So what implications do these changes have for the roofing contractor With regards to the underlay the supplier will print a zonal classification table on the underlay wrapping label This will provide the user with information on geographical zone suitability and maximum recommended batten spacings So for example an underlay with a measured wind uplift resistance of not less than 1900 N m2 can be used in all UK zones at batten gauges up to 345mm This can be reduced to 1600 N m2 in buildings that have well sealed ceilings There are limiting factors within these recommendations for example the ridge height must not be greater than 15 metres or the site altitude must not be greater than 100 metres and the site topography is not classed as significant Where a site is outside these conditions a calculation is required to determine the required wind uplift resistance of an underlay The roofer should request this from the underlay supplier To comply with the new requirement to mechanically fix ridge and hip tiles the obvious solution is to use dry fix systems These offer the installer many advantages that are well understood such as speed and ease of installation the ability to work without worrying about the imminence of frost or rainfall etc as well advantages within a roof system such as the provision of roofspace ventilation and the ability to cope with structural movement etc However there are circumstances where it is still appropriate to use mortar bedding for example on heritage work and for roofing tiles such as traditional clay pantiles or handcrafted clay plain tiles The easiest way to mechanically fix a ridge tile is to use ridges that are pre holed by the manufacturer and use screws with sealing washers to secure each ridge tile to the ridge or hip batten On trussed roofs where there is no ridge tree a timber ridge batten can be secured to the apex using suitable straps or brackets Seek advice on suitable mechanically fixed mortared ridge and hip details from the roof tile manufacturer Perhaps the change that will have the greatest impact on the roofing contractor though will be the higher theoretical wind loads that will mean greater and more tile fixings Because most if not all roof tiles will now require fixing the roofer will need to find different
