1 CI/SfB January 2015 (47) t6 Uniclass L524<L Issue 03 & Accessories A Range of Tubular Washers, Plates and Screw Fasteners Introduction A range of specialist fasteners for securing thermal insulation and Icopal single-ply roof waterproofing membranes to a variety of structural roof decks including steel, concrete and timber. Icopal Tubular Washers Icopal Tubular Washers are precision moulded from high grade polypropylene and extensively tested to ensure resistance to the extreme temperatures and mechanical stresses encountered within the roofing system. They are blue in colour and are available with two washer diameters: A 45 mm diameter for fixing membranes and a 75 mm diameter for fixing rigid insulation boards. are manufactured from high grade carbon steel which are case hardened to achieve the properties essential for long term performance and have an organic corrosion resistant finish to meet UEAtc Part 2 requirements. The fasteners are also available in austenitic stainless steel offering exceptional corrosion resistance for extended warranty projects. Icopal Stress Plates Icopal Stress Plates are manufactured from high quality carbon steel. Icopal Stress Plates are for use where tube washers cannot be utilised or where the membrane is being fastened without insulation present, eg cold roof situations.

7 Icopal Tubular Washers Composition Icopal Tubular Washers are blue in colour and precision moulded from high grade polypropylene and extensively tested to ensure resistance to the extreme temperatures and mechanical stresses encountered within the roofing system. The Icopal Tubular Washer System offers many benefits over other traditional fastening methods. Membrane protection Foot traffic or other loads applied to the roof surface can often force the fastener head to pop through the membrane as the insulation beneath compresses. This causes damage to the waterproofing membrane and therefore potential roof leaks into the structure. Thermal transmittance Traditional fastener and metal plate combinations create a path for heat loss from the inside of the building to the outside atmosphere. This seemingly small thermal bridge creates significant heat loss. This loss has to be factored in when calculating U-values to BS EN ISO This can result in an increase in the insulation thickness to compensate. The Icopal Tubular Washer eliminates this thermal transmittance thereby allowing a reduced thickness of insulation. Insulation thickness Regulations are constantly being upgraded to help reduce a building s carbon usage, leading to thicker insulation being required. Thicknesses of up to 595 mm can easily be accommodated with the Icopal Tubular Washer and Screw Fastener combination. Eliminate unwinding forces The cyclic nature of wind uplift on flat roofing systems can cause standard fastening methods to unwind. Icopal Tubular Washers and Screw Fasteners can allow this cyclic action to occur without causing the fastener to unwind. The telescopic action of a tube and fastener combination that is not locked together removes the risk of the fastener being pushed through a thin deck by foot traffic or materials being placed on the roof surface

9 Icopal Stress Plates Introduction There are often situations when the Icopal Tubular Washers cannot be utilised, for example when the membrane is not being fastened directly to insulation, such as in a cold roof situation, or when fastening membrane which is applied directly to a plywood overlay. For these situations the Icopal Stress Plates are used. These plates are purpose-designed for use with fasteners from the Icopal range and are manufactured from from a high quality carbon steel. If further advice is required please contact s Technical Services for guidance.

Examples of Typical Usage Cold Roof Application (timber deck) Suitable Fasteners: Seam Plate Type: Icopal IRC/W-82x40mm Stress Plates Warm Roof Insulation with Plywood Overlay Suitable Fasteners: (to suit structural deck type) Seam Plate Type: Icopal BS-S-4.8mm Stainless Steel Fastener Icopal TI-T25 6.3mm Carbon Steel Fastener Icopal IRC/W-82x40mm Stress Plates Membrane Overlay above Soft Insulation (eg mineral wool) Suitable Fasteners: (to suit structural deck type) Icopal BS-S-4.8mm Stainless Steel Fastener Icopal TI-T25 6.3mm Carbon Steel Fastener Seam Plate Type: Icopal IRD/82x40mm Stress Plates Icopal IRD/82x40mm Stress Plate for use when fixing waterproofing membrane in seam, over insulation Icopal Stress Plates Item Code Pressure Plate TBC IIcopal IRC/W-82x40mm Stress Plates 100 TBC Icopal IRD-82x40mm Stress Plates

10 Guidance Notes examples only Selecting the correct tube washer To optimize the benefits of the Icopal Tubular Washer system, ideally use the maximum length of tube washer and the minimum fastener length available. In certain applications, such as over-roofing of existing membrane and insulation layers, different tube lengths may be required. The tube washer should be chosen first; then the fastener can be selected. To select the maximum tube length (C) : i) deduct minimum 15 mm from the total build-up of the roof insulation (A) to allow for compression of the insulation (B). ii) choose the tube washer of that length or shorter. eg, For an insulation buildup of 140 mm, the maximum tube length would be 125 mm, and so a 105 mm long Tube Washer would be chosen. Total Roof System build-up (A) Deduct compression tolerance (B) Maximum tube length 140 mm -15 mm 125 mm Chosen tube length (C) 105 mm Selecting the correct fastener length When selecting the correct Icopal Screw Fastener length, allow for the recommended minimum deck penetration or embedment and take into consideration the total build-up of the roof system, including any pressure plate, membrane, separation layers insulation, vapour barriers, existing systems and structural deck. Key: A: Total roof buildup depth B: Insulation compression tolerance ( min 15 mm) C: Tube Washer length D: minimum deck penetration or embedment E: min 20mm allowance for fastener in tube F: Fastener length To select the optimum fastener length (F) for tube washer applications: eg, For a 140 mm build-up over 0.7mm steel deck using a 105 mm tube the minimum fastener length would be 70 mm. i) take the total roof system build-up measurement (A) and deduct the selected tube length (C). ii) iii) allow for deck penetration (D) and then add minimum 20 mm allowance for the fastener within the tube (E). select the fastener at this length or longer. Total roof system build-up (A) Deduct selected tube length (C) Add min. deck penetration/embedment (D) Add allowance for fastener within tube (E) Minimum fastener length (F) 140 mm -105 mm +15 mm +20 mm 70 mm

11 Guidance Notes examples only Washer/Fastener Combinations The following tables are provided as a quick reference guide for calculating the required tube washer and fastener combination for a new warm roof direct to deck. The thickness of structural deck used for the combination is indicated for each table. The fastener length should be altered accordingly where the structural deck thickness or system build-up is different. See previous page for further information.

13 Icopal Fasteners & Accessories A Range of Tubular Washers, Plates and Screw Fasteners Quality Assurance Icopal Tubular Washers, Pressure Plates and Screw Fasteners are supplied under a Quality Management System approved to ISO 9001: 2004 by Swiss Association for Quality and Management Systems. Insulation Attachment Icopal Thermazone PIR insulation boards should be attached at the minimum rate of 11 tubes & fasteners per 1.2 m x 2.4 m board (unless otherwise specified and approved). An increased density may be recommended depending on project location, height and exposure etc. Delivery and Storage Items are delivered in boxes. Keep the materials in unopened packaging prior to use, reseal any damaged packing. Technical Services Specialist advice and design guidance on all matters relating to Icopal Tubular Washers, Pressure Plates and Screw Fasteners is freely available from our Technical Department at the address below. Membrane Attachment For every mechanically fastened roof, a wind uplift calculation and fastener specification will be required prior to installation of the Icopal roof waterproofing membrane. All calculations are conducted in accordance with BS 6399 or BS EN 1991 parts 1-4, as appropriate. Fastener Application No pre-drilling is necessary for timber and steel decks. Simply insert the fastener through the tubular washer and install with a standard clutch drive electric screw gun ( rpm). Optimum fastener performance is achieved when fastener is installed perpendicular to the deck and into the top flutes of a steel deck. The TX-25 recess provides excellent drivability and the drill-point design cuts a hole in the steel deck maintaining contact between the deck and the minor diameter of the fastener, increasing back-out resistance.
