2 RIGIDAL ZIP LOK SYSTEM An advanced zip-up standing seam roofing system with unique halter design Rigidal Ziplok is a BBA approved, advanced zipup standing seam system that creates a continuous weathertight roof. The side laps are zipped up in conjunction with a unique halter system that is fixed directly to the supporting structure without penetrating the external weather sheet. This method of secret fixing creates a structurally sound roof that gives excellent resistance to wind uplift with outstanding aesthetic properties. The Systems Approach Ziplok typifies Rigidal s systems approach to roofing. By offering a complete range of complementary products, we are able to ensure compatibility between components, and more importantly ensure that we provide a roof which performs according to its design criteria in all respects. Apart from the benefits of one stop shopping, the complete approach to the whole system is the only way that the integrity of that system can be guaranteed, or that it can be shown to have compliance with the ever more stringent Building Regulations and Technical Standards. Other benefits of buying from a single source include being able to eliminate problems of colour matching or other incompatabilities, since we are able to ensure that fascias and accessories are produced from the same batch of coated coil as the top sheet. More importantly, the systems approach enables us to calculate variations in terms of acoustic properties and thermal transmissions to suit different applications, as well as loading capabilities, impact resistance etc. Unique Halter Building upon the ever increasing demand to further improve thermal efficiency, Rigidal has developed the unique Thermohalter. Utilising a resin based material originally developed for the space industry, thermal transmission through the halter is virtually zero, achieving a part L compliant system which provides 0.25 U values as standard and with 0.2 and 0.16 also available. In addition, the exceptional thermal efficiency of the Thermohalter allows the system height to be reduced, both improving the aesthetics and reducing overall construction costs still further. Widths/dimensions Ziplok is available in three standard widths of 300, 400 and 500mm. In addition, Ziplok can be produced in non-standard widths at any size from 240mm to 580mm, providing a very cost effective way of finishing roofs and also allowing laying of the sheets to take place from both ends of the roof simultaneously. It also allows designers the freedom to choose the module width or even to mix widths on a single roof. Cost effective As the layout of the liner sheet effectively sets out the halters on site, Ziplok is particularly quick and easy to install when used in conjunction with the Thermohalter. In addition the design of Thermohalter means that the Ziplok sheet snaps onto the halter and therefore does not have to be zipped one sheet at a time, so increasing the speed of construction still further and providing an exceptionally user friendly and cost effective construction. If required, Rigidal Ziplok can also be provided as a bar and bracket system using Corogrid as the spacer system. 2 RIGIDAL ZIPLOK - Zip-up standing seam roof system

3 STANDARD WIDTHS ZIPLOK ZIPLOK ZIPLOK 500 BESPOKE WIDTHS Materials Offering the ultimate in design flexibility, Rigidal Ziplok is available in aluminium, steel, stainless steel, zinc, copper or clad alloy. Rigidal has eight roll forming machines, three of which are mobile providing on-site manufacture where required. This allows very long sheet lengths to be produced eliminating the need for endlaps and greatly increasing the speed of construction. In addition, Rigidal Ziplok can be smooth curved down to radii as tight as four metres convex or eight metres concave, as well as crimp curved, tapered or wave formed.

4 Rigidal Ziplok Roof Envelope Solution Roof failure is the largest single source of litigation in the UK construction industry. Rigidal Ziplok Systems overcome the many issues that can seriously impair the performance and lifespan of metal roofing systems. No Leaks Leaking roofs are accountable for more roofing defects than all other issues put together. Secret fixing to avoid water penetration via the primary fasteners is a step in the right direction, but falls a long way short of providing a complete solution. Approximately 90% of all reported roof leakage is experienced within 10% of the total roof area at perimeter details. Regardless of the degree of fall on a roof slope hips, ridges and penetrations can all be a source of water ingress. Eaves/gutter junctions and verges on lower roof pitches can also become points of water entry. Perimeter Detailing Water ingress at perimeter details is avoided by overlapping and interlocking the upstand seams of Rigidal Ziplok sheets. This ensures that any water is directed towards the eaves and not back into the building. For low pitch applications the eaves overhang on the topsheet can be turned down to increase the angle of run off by approximately 20. This is sufficient to prevent the possibility of water entering the building via the junction with the gutter. At hip and ridge positions, the profile can be turned up to form an apex dam across the width of the panel. This detail and the standing seam side lap detail is then overlapped by the verge. Secretly Fixed Rigidal Ziplok features a secretly fixed true standing seam side lap detail which provides a continuous weathertight roof and excellent protection in all weather conditions. Long Lengths Rigidal Ziplok is available in very long lengths and can be rolled on-site where sheet lengths exceed that which can be delivered by road. This eliminates the need for end laps and consequently the potential for water ingress. The unique design of Rigidal Ziplok addresses the problem of leakage without an over reliance on sealants or a myriad of components.

5 Rigidal Ziplok Roof Envelope Solution Outstanding Structural Performance Structural performance is another major factor that can result in roof failure. Again Rigidal Ziplok provides an ideal solution to the most commonly experienced problems. A Complete Roof Envelope Rainwater solutions Soffit sheeting Rigidal Ziplok standing seam system Halter combined with zip-up standing seam detail provides exceptional weathertightness and resistance to wind uplift Eaves fascia solutions Factory fabricated corner units Curved or straight barge boards Wind Uplift Rigidal Ziplok standing seam roofing systems provide excellent resistance to wind uplift due to their unique fixing method. The thermally broken halter firmly secures the roof system to the steelwork below. The strength of this joint and fixing detail is completed by zipping the side laps together to create a secretly fixed roofing envelope with outstanding structural performance. A full range of integrated fascias, gutters and flashings are also available providing the designer/specifier with a complete one-stop roofing solution. Made to individual specifications, all are designed to complement the outstanding aesthetic and performance standards of Rigidal Ziplok. Factory assembled rooflights and a full range of of fasteners and fixings completes the comprehensive package.

6 Rigidal Ziplok System Options Thermohalter Rigidal s unique Thermohalter can be used in the traditional Rigidal Ziplok system without cold bridging through the system. The liner sheet acts as a template for setting out the halters on site, making this system not only world beating in terms of performance but also very cost effective, quick and easy to install. Bar and bracket If required, Ziplok can be used in a bar and bracket system, where the traditional aluminium halter is mounted on a galvanised rail which in turn is mounted on galvanised brackets. Rigidal recommends Corogrid as the bar and bracket system in this application. 6 RIGIDAL ZIPLOK - Zip-up standing seam roof system

7 Rigidal Ziplok System Options Acoustics Rigidal Ziplok is available in numerous acoustic systems. By using a variety of insulation thicknesses and densities a whole host of performances can be achieved. The standard 0.25 U value construction also achieves better than 40dB sound reduction. By utilising perforated liner or deck in conjunction with a high density layer of insulation, significant sound absorption can be achieved. Three layer systems can be purpose designed to achieve a combination of both sound absorption and sound reduction. Our acoustic systems are regularly used in schools, residential projects, sports halls and hospitals. Structural deck Structural decking offers a simplified method of construction by dispensing with the need for purlins. The structural deck is used to span the portal frames of the building, thereby using fewer components and giving clean lines to the interior of the building. Decking can be non perforated, web or fully perforated allowing acoustic requirements to be accommodated within this system. Rigidal also offer a range of structural liner trays, both solid and perforated, which while normally used in wall applications can also be applied in roof applications where a flush interior finish is required. 7

8 Rigidal Ziplok Tapers and Curves Tapers Rigidal s Ziplok panels are available rolled tapered, with the UK s first tapering machine. Previously, any tapering of sheets had to be carried out by cutting and welding tapered blanks then roll forming, with the inevitable labour costs which this incurred. The state of the art tapering machine is believed to be the only one capable of rolling tapers in a single pass from coil, and allows the production of tapered sheet at a similar rate to parallel sheet. The roll former is also mobile, allowing tapering to be carried out on site if required, which in turn means that, unlike our competitors, the length of tapered sheet is no longer restricted by transport or production capability. Tapers can be from a minimum width of 240mm at one end to 580mm at the other end, on sheets with a minimum length of 3.5m and up to any length maximum. Tapered sheets will self curve to a 40m radius and can be machine curved to 20m radius if required. Curves Rigidal Ziplok can be curved in a variety of options to suit the required application. The profile can be concave, convex or wave shaped, incorporating both curves in one sheet. Profiles will self curve to a large radius, otherwise they can be mechanically smooth curved down to 4m radius convex curves or 8m radius concave curves. If required, profiles can be crimp curved down to 600mm radius. In all cases, the micro ribbing of the Ziplok profile helps to produce a clean, crisp curved appearance. 8 RIGIDAL ZIPLOK - Zip-up standing seam roof system

9 Rigidal Ziplok Safety Systems Rigidal Systems prides itself on the designed-in safety of its roofing systems. As part of our systems approach to the roofing envelope we also offer a range of walkways and fall arrest systems designed to ensure that ongoing maintenance of the roof can be carried out in complete safety, confident that the safety systems are wholly compatible and have been tried and tested with the roof structure. Fall arrest systems Rigidal s fall arrest systems use either a 8mm 316 stainless steel cable, a unique 16mm polyester parallel fibre cable, or an extruded aluminium rail. All systems offer exceptional benefits and the polyester cable is available in a range of colours to suit a building s exterior. Walkways and access systems Designed to complement the Ziplok standing seam profiles, Safegrip provides a safe walkway system which also removes the risk of damage from foot traffic. Using the unique attachment system, no fixing through the outer skin of the roof is required so the walkway does not compromise the integrity or performance of the Ziplok system. 9

No premium is directly payable by the client or the main contractor as this is covered by Rigidal Systems pricing policy. The process by which a warranty is arranged starts at design stage where the architect should specify that the QA+ Guarantee is to be in place. This will require that the roofing contractor is to be vetted, approved and part of the scheme. All drawings will be vetted by the main contractor and work will be inspected at various stages during the course of construction. On completion, the warranty will be issued, confirming that the whole roof system and all components have been vetted and approved. An important aspect of the service is that it ensures that only Rigidal s first class components find their way into the roofing system, where often components can be substituted by inferior products. The vetting process also ensures that any potential problems of design or workmanship are identified at an early stage and rectified before completion of the roof, so ensuring that any problems with the completed project are less likely to occur in the first place.
