Multiplex-top Data Sheet GUTEX Multiplex-top is a rain-tight sarking board with single-ply construction, homogenous cross-section and paraffin impregnation. Photographic images are property of GUTEX archive Technical Data Joint type – Rain-tight sarking – In above-rafter constructions as sarking over GUTEX Thermosafe-homogen Actual coverage, length x width (mm) Square metres per board (m2) Weight per board (kg) Weight per m (kg) – 18 mm GUTEX Multiplex-top boards are only suitable for use with above-rafter insulation. – All GUTEX Multiplex-top boards, except those that are 18 mm thick, are suitable for installation directly over rafters. Advantages – Consistently uniform board dimensions make installation quicker and easier Square metres per pallet (m ) – Homogeneous, single-ply construction – Wind tight Nominal thermal conductivity λD(W/mK) – Extra covering or taping of the joints is unnecessary if used with 22, 28 and 35 mm thick boards for pitches greater than 15°. Additional covering and taping of joints is unnecessary for 18 mm boards if the roof pitch exceeds 20°. Vapour diffusion factor (μ) – Suitable as temporary roof covering (max. 3 months) – Adhesive nail tapes or sealants are not required Compressive stress/ strength (kPa) – Ideal for upgrading the thermal insulation of existing structures Tensile strength perpendicular to board surface (kPa) – Reduces thermal bridging – Superior thermal storage capacity provides outstanding insulation against heat in the summer. Short-term water absorption (kg/m²) – Significantly improves soundproofing Specific heat capacity (J/kgK) – Regulates humidity Fire reaction Euro Class as per DIN EN 13501-1 – Allows vapour diffusion – Guaranteed by Germany's Association of Roofers – Wood is a sustainable, recyclable natural resource. – Made in Germany – Biologically safe (natureplus® certified) Dry manufacturing technique with designation: WF-EN 13171-T4-WS 1,0-CS(10/Y)100TR40-MU3-AF100 *Approval No. 23.15-1404. German disposal category: A2 (treated wood; without non-halogenated organic compounds) Code number as per AVV:030105; 170201 Composition Manufactured from untreated Black Forest spruce and fir – Additives: • 4 % polyurethane resin • 1.5 % paraffin

– Store and install this product dry. – Always install the boards so the side with the marking is exposed on the exterior of the building. GUTEX Multiplex-top 22 / 28 mm Nails per linear metre of batten – Max. rafter distance (centre-to-centre): – Board joints must be butted tightly. – Avoid walking on areas between the rafters. 30 x 50 mm batten cross section Snow load (kN/m2) 0.75 – Immediately install battens after installing boards. – Adhesive nail tapes or sealants are not required. Nails per linear metre of batten – Avoid cross joints. 5.0 x 140 mm nails  (Power nails 3.8 x 130 mm) 40 x...
