APPLICATION The BENCHMARK Roofliner system is to be used as an insulated composite roof deck under site applied single-ply membranes or fully supported or self-supported aluminium, copper, zinc and stainless steel cladding systems. Flat or pitched finished roof slopes to suit the membrane and or metal standing seam roof system or curved (convex and concave) roofs with a radius greater than 25 metres (see PANEL SIDE JOINT clause below).

PRODUCT TOLERANCES Length 3mm +3mm Width 1mm +1mm Thickness 2mm +2mm End Squareness 2mm +2mm Flatness (per metre) 2mm +2mm AVAILABLE LENGTHS Standard lengths 1.8 to 12metres. 12 to 16 metres can be supplied but are subject to additional transport surcharge. PANEL END All panels are produced flush-ended. It is recommended that panels are used in continuous lengths from ridge to eaves with no end joints. However, where an end lap must be used the panels must be butt-jointed to each other and sealed with continuous self-adhesive film backed butyl mastic tape on the external face. FACTORY APPLIED WEATHER SEALS Continuous bead (approx. 7mm x 10mm) is factory applied in the female joint on the external face side. External Face Internal Face Compressed FAWS Page 1 of 5
PANEL SIDE JOINT Tongue and groove joint inter-fit achieves excellent thermal performance. At less than 50 metres radius, the joint should have site applied Premier Sealants SGV20 PVC tape of appropriate size to suit gap between joint. Consult BENCHMARK Technical for more information.

PERFORMANCE Thermal Insulation The Roofliner panels have a Thermal Transmittance (U value), calculated using the method required by the Building Regulations Part L2 (England & Wales) and Section 6 (Scotland) Technical Handbooks. Core Thickness (mm) 80 100 125 150 175 200 220 U value (W/m 2 K) 0.25 0.20 0.16 0.13 0.11 0.10 0.09 Biological The Roofliner system is fibre-free and immune to attack from mould, fungi, mildew and vermin and therefore forms no health and safety risk to building occupants. No urea formaldehyde is used in the construction, and the panels are not considered deleterious. Fire The steel outer and inner facings have Class 0 surface spread of flame as defined by Building Regulations. Class 1 to BS476: Part 7: 1997 and Fire propagation index, I = 5.4, Sub index, i 1 = 3.5, i 2 = 1.9 & i 3 = 0.0 to BS476: Part 6: 1989. Acoustics All Roofliner panels have a predicted single figure weighted sound reduction Rw = 24dB.

Structural Notes: 1. Values have been calculated using the limit state method described in the European Recommendations for the Design of Sandwich Panels (ECCS document No.115 2001), taking imposed loads, temperature and creep into account. 2. For each value individual and combined load cases with appropriate load factors and temperatures have been considered. 3. The load tables are for dark coloured panels. 4. The following deflection limits have been used: Pressure loading L/200 Suction loading L/150 5. For intermediate values linear interpolation may be used. 6. The actual wind suction load resisted by the panel is dependent on the number of fasteners used and the material of the purlin. The fastener calculation should be carried out in accordance with the appropriate standard. For further advice please contact BENCHMARK Technical Services. 7. The allowable steelwork tolerance between bearing planes of adjacent purlins is L/600. Where L is distance between supports. Page 5 of 5
