13 CEILING SYSTEMS Product description best wood CLT BOX is a statically effective and at the same time spacecreating wood element, which is suitable for all construction requirements thanks to its versatile dimensions and excellent construction characteristics. A high-performance and versatile building product is created by utilising the advantages of solid timber and wood frame construction. The combination of CLT and ribbing planks produces a high static load-bearing capacity with a comparatively low weight. The crosswise assembly from high-quality raw material in combination with high-quality gluing of edges and surfaces guarantees a high degree of dimensional stability. A high degree of prefabrication of the best wood CLT BOX with downstream cut-off and the simplicity of joining the best wood CLT BOX elements ensures swift and cheap installation and guarantees dry construction. It is simple to produce building element constructions with increased fire resistance with evidence from the best wood STATICS software. Advantages high static load-bearing capacity with comparatively low weight large spans and therefore prop-free rooms possible low structure height high degree of prefabrication and simple joining of the ceiling elements for swift and cheap installation utilises advantages of solid timber and wood frame construction high resistance to fire high-quality ready visual quality on the underside with additional surface finishing possible Laying variant best wood CLT BOX CEILING Version 25 9 x 30 mm separate tongue Standard rabbeting 23/51 mm Height: mm Inlay board/separate tongue Inlay board for forming the ceiling section Three-layer board with building approval, 22/100 mm in 5.00 m/pieces Separate tongue Multiplex birch, 9/30 mm in 5.00 m/pieces Our production according to your schedule JUST IN TIME!

Product description best wood CLT BOX is a statically effective and at the same time space-creating wood element, which is suitable for all construction requirements thanks to its versatile dimensions and excellent construction characteristics. A high-performance and versatile building product is created by utilising the advantages of solid timber and wood frame construction. The combination of CLT and ribbing planks produces a high static load-bearing capacity with a comparatively low weight. The crosswise assembly from high-quality raw material in combination with high-quality gluing of edges and surfaces guarantees a high degree of dimensional stability. A high degree of prefabrication of the best wood CLT BOX with downstream cut-off and the simplicity of joining the best wood CLT BOX elements ensures swift and cheap installation and guarantees dry construction. It is simple to produce building element constructions with increased fire resistance with evidence from the best wood STATICS software. Download Certificates In approval procedure! 24

29 Product description Glued beams produced from mountain larch are the ideal material when great importance is placed upon high form maintenance and dimensional stability. Even when large sized and long construction elements are produced, the timber does not twist and is, to a great extent, free of any cracking. Unlike the Siberian larch, which is very light and has black knots, we exclusively use highest quality central European mountain larch originating from the alpine regions. This mountain larch has a well-formed knot structure and its deep and strong colouration is decisive for satisfying our high quality demands. Our glued beams have secured quality, as the complete production process is subject to strict internal and external inspection. Our production according to your schedule JUST IN TIME!

Download Certificates Product description/application DUO/TRIO-BEAMS are especially suitable for all applications with high demands on form stability of the wooden parts. In particular, they are ideal for exposed applications which must meet high aesthetic requirements without the use of chemical wood preservation. The solid wood appearance and character is maintained by the use of very few joins in production. DUO/TRIO-BEAMS for use in exposed applications are exclusively made from North Scandinavian spruce originating only from PEFC certified mixed woodlands. In our opinion, it is the very best spruce available currently in terms of its superior visual quality and high stability. DUO/TRIO-BEAMS may only be used in application classes I or II (interior room climate or external climate under roofing). Due to their good form stability and low wood moisture, DUO/TRIO-BEAMS are especially suitable for timber building construction. The low level of timber moisture means that chemical treatment of the timber is unnecessary, should the construction regulations contained in DIN be fully respected. 30

The desired surface qualities can be found in the above table. Deviations from this information are to be separately contractually agreed. Transportation and installation; constructional instructions Elements are packed in wrapping foil at the factory, so they are protected during loading, transportation, and brief intermediate storage. The transport packing only provides short-term protection and should be removed as soon as possible due to the danger of condensation formation leading to blue stain and mould growth. The elements are then to be protected with suitable coverings against moisture penetration, direct sunlight and dirt. The outer layers of the elements, in particular, absorb moisture in the state of construction. This building moisture must be gradually shifted to the equilibrium moisture content of later use. Careful heating and airing, and the consequent slow reduction of the relative air humidity and corresponding wood moisture, is conducive to this. Depending on the environmental conditions, shrinkage cracks can occur on the surfaces of the elements including along the glue line because of the wood s natural swelling and shrinking behaviour. In elements without systemic transverse stress such shrinkage cracks can be tolerated up to a depth of 1/6 of the element width (each side), in elements with planned transverse stress up to 1/8 of the element width (per side). The tendency towards crack formation grows where there is direct weathering and strongly changing climatic stresses. At the planning stage, protective measures should already also be envisaged for the state of construction. These include, in particular, covers and unimpeded water drainage. It is recommended that coatings only be applied once the equilibrium moisture content has been achieved. Glue joints in elements made of larch sometimes tend to open up when exposed to direct weathering, because of intracellular substances. We therefore recommend that glulam made from larch be built exclusively into the use classes I and II. 37 APPLICATION
