Instructions for use - tender specifications for UNIGLAS FACADE: The performance limit is the glued laminated timber post and beam construction to be provided by the customer. The minimum timber quality of the construction must correspond to grade GL 24 for glued laminated timber. The minimum width of posts and beams is 60 mm. The structural design must prove that the beam has a maximum deflection of l/500 from the weight of the beam itself including the weight of the insulating glass. Contrary to DIN 18202:2013-04 and DIN 18203-3:2008-08, the installation inaccuracy (dimensions) of the post and beam construction is maximum ± 2 mm (=> maximum tolerance 4 mm) with regard to the reference point of a reference axis both in height and in the axes. The offset of the posts from the beams at the level of the insertion elements must not exceed ± 0.5 mm. The maximum sag of the beams must be limited to fmax l/500. Beam axis 2 Beam axis 1 h Nominal axis dimension ± 2 mm Beam axis 0 Post axis 0 1 2. n b n Nominal axis dimension ± 2 mm Example of installation inaccuracies for nominal dimension transgression with the post (beam dimension h arises parallel to reference point = post axis 0 / beam axis 0): Other performance limits are lateral building connections, as well as connections to the base, eaves or attic, including insulation and cladding with flashings, as well as exterior sun protection. The glazing is not further specified. Any functional glazing from the corresponding proposal, the UNIGLAS product range or even panels, PV or solar thermal energy modules in insulating glass technology can be used here. Tenders for a window and/or glazed doors with turn-tilt function as an insert element are invited by way of example. Accordingly tenders are also invited for sliding sashes or lift-slide sashes as an insert element, as presented in the guiding notes.
UNIGLAS Tender Specifications for Special contractual conditions: Insulating glass elements The insulating glass elements used and integrated must bear the CE mark, as well as the Ü-mark for multipane insulating glass in Germany in accordance with Bauregelliste A, Part 1, Annex 11.10.

In particular the glass thicknesses of the insulating glass elements must be determined and the supporting insulating glass bond for the loading conditions, wind suction and climate load, the bond of the connecting rod and the attachment of the TCG element to the substructure including the normal and shear stress must be verified. The submission of a structural analysis is also permitted by way of evidence. Corresponding component tests must be submitted for own weight deflection of the insulating glass, as well as for evidence of the emergency support in the event of failure of the static adhesive joint.

The connecting rod must be checked for dust, damages and timber humidity and expertly glued to the insulating glass, which has been cleaned beforehand, using Ottocoll S 660, observing defined adhesive geometry, ensuring that there are no holes or bubbles and with the correct interlocking arrangement according to the workshop drawing supplied. The adhesive surface on the connecting rod must be free of varnish residue. Rods that do not meet requirements must be sorted out and may not be used. The adhesive geometry must correspond to the static calculation. The adhesion may not take place on the construction site. The adhesive joint must be fully hardened in according to manufacturer's specifications before installing the TGC element. The dimensional accuracy, planarity and parallelism of the glued laminated timber post and beam construction provided by the customer must be checked and the tolerances determined before installation. The timber construction must be masked with a compressible Duplocoll adhesive tape before inserting the elements to ensure air and driving rain impermeability and to serve as a vapour barrier. Longitudinal joints in the adhesive tape on the post must be avoided. The connection joint of the adhesive tape on the beam must be tight i.e. free of open joints. Any unplanned moisture penetration into the elements during installation must be avoided. The TGC element must be hoisted, aligned and screwed to the post and beam supporting structure. When screwing the TGC element to the supporting structure, it must be ensured that glass substrate and the thick layer of varnish on the connecting rod is not damaged.
