Deck construction and landscaping massaranduba low medium (Manilkara spp.) high BULK DENSITY COMPRESSIVE STRENGTH General details: • origin: Northern to central South America, trade name encompasses various species • Colour: Meaty red colour, later darkening to dark brown • Durability class: 1–2 • Properties: High swelling and shrinkage, satisfactory to moderate dimensional stability, extremely high strength, high hardness, homogeneous texture. DEFLECTION RESISTANCE Application: Deck construction, floors subject to heavy loads, noise barriers and privacy screens, fencing, structural timber, sometimes used in water engineering. E-MODULUS HARDNESS DURABILITY DIMENSIONAL STABILITY – Extremely low dimensional stability – often originates from overexploitation (use only certified timber wherever possible) – We consider permanent, secure fastening to be highly critical + High durability + Extremely high strength + High hardness Kapur Installation instructions: The installation is extremely dependent on the timber’s moisture level. The wood moisture must always be determined before installation. Ask your timber supplier for more information. Fastening recommendation: For timbers with high wood density and/or moderate dimensional stability, direct fastening of the boards is preferable to indirect. This applies above all to board thicknesses > 25 mm. For direct fastening, use Terrassotec A4 5,5 mm in combination with the Dista-Leiste 2.0 or profile drilling screw A4 5,5 mm for Eurotec aluminium profiles. It is always advisable to drill a pilot hole with a drill stop. Nevertheless, we cannot provide a general recommendation, as damage is repeatedly found to occur with this type of timber. (Dryobalanops spp.) low medium high BULK DENSITY COMPRESSIVE STRENGTH General details: • origin: Southeast Asia, trade name encompasses various species • Colour: Orange to reddish brown, darkening to brown • Durability class: 1–2 • Properties: Moderate to high swelling and shrinkage, satisfactory to moderate dimensional stability, homogeneous texture. DEFLECTION RESISTANCE Application: Deck construction, fencing, structural timber E-MODULUS HARDNESS Installation instructions: • Centre distance in substructure: max. 60 cm • Joint width between the boards: 6 to 10 mm • Spacing between the butt joints: 3 to 4 mm DURABILITY DIMENSIONAL STABILITY + High durability Ipé, – Possible erosion of constituent substances in the timber – often originates from overexploitation (use only certified timber wherever possible) – moderate hardness – moderate dimensional stability Fastening recommendation: For timbers with high wood density and/or moderate dimensional stability, direct fastening of the boards is preferable to hidden. This applies above all to board thicknesses > 25 mm. For direct fastening, use Terrassotec A4 5,5 mm or Profile drilling screw A4 5,5 mm for Eurotec aluminium profiles. It is always advisable to drill a pilot hole with a drill stop. Lapacho (Tabebuia spp.) low medium high BULK DENSITY COMPRESSIVE STRENGTH General details: • origin: Northern to central South America, trade name encompasses various species • Colour: Light brown to light yellowish brown, later darkening to brown to olive brown • Durability class: 1–2 • Properties: Moderate to high swelling and shrinkage, good dimensional stability, extremely high strength, very high hardness, homogeneous texture. DEFLECTION RESISTANCE Application: Deck construction, bridge construction and shipbuilding, floating jetties, fencing, parquet, floors subject to heavy loads, approved structural timber, sometimes used in water engineering. E-MODULUS HARDNESS DURABILITY DIMENSIONAL STABILITY + High durability + good dimensional stability + Extremely high strength + Very high hardness + approved structural timber – often originates from overexploitation (use only certified timber wherever possible) Installation instructions: • Centre distance in substructure: max. 60 cm • Joint width between the boards: 6 to 8 mm • Spacing between the butt joints: 3 to 4 mm Fastening recommendation: For timbers with high wood density and/or moderate dimensional stability, direct fastening of the boards is preferable to hidden. This applies above all to board thicknesses > 25 mm. For direct fastening: Terrassotec, hardened stainless steel, 5,0 and 5,5 mm; Hapatec, hardened stainless steel, 5,0 mm; or Profile drilling screw, hardened stainless steel, 5,5 mm for Eurotec aluminium profiles. It is always advisable to drill a pilot hole with a drill stop. *Solid wood decking is not part of our product range. This short overview represents a planning aid. 22
