In the course of the planning of the new construction of an engineering office for technical building equipment, you should not just create modern inner workplaces in an optimal environment, but the company's external appearance should additionally express the flexibility and innovative spirit of your enterprise. The planning result complies with the following requirements: the two-storey office building, built on a Y-shaped floor plan, is pleasantly set apart from the simple commercial building predominating the area thanks to its idiosyncratic shape.

The facade design should comply with the said central planning principle. This is the reason why the client opted for the MF-Design 35-5 profile made by the Germany company Montana Bausysteme AG, an evenly perforated aluminium profile equipped with a sawtooth-shaped cross-section which can be supplied in lengths of up to 6 metres with an element width of 440 mm. The colour-coated perforated sheet should also have a coloured background, for which the roofing company Voss GmbH recommended the DELTA®-FASSADE COLOR PLUS facade membrane we have just launched. This highly vapour-permeable, waterproof membrane, corresponding to the fire class B, is specially designed for this application area and is available in rolls of 30 m x 1.5 m. After having carried out a preliminary sampling with different colour variants, the choice fell on a bright coral red, which impressively enhances the three-dimensional effect of the facade.
Aluminium profiles were used for the vertical supporting substructure with adjustable installation depth. The external thermal insulation in between was attached to the masonry by means of plate anchors. Above this - starting at the base - the first facade sheet was laid horizontally by temporarily fixing it on the substructure. Our tapes and adhesives are perfectly suitable for this purpose. During the installation of the membrane, you had to particularly focus on the fact that the surface did not form any bulges or creases because the resulting shadow effects, which are clearly visible due to the transparency of the cladding material, may decisively influence the overall impression. The dimensional stability and "boardiness" of the approx. 300 g/sqm heavy membrane largely accommodates the required even installation. To permit an immediate relief of the temporary adhesive points, the horizontal substructure made of aluminium hat profiles was installed immediately after the installation of each strip and screwed to the vertical substructure. They had previously been coated in the same colour as the facade membrane. We offer the universal dispersion paint DELTA®-FAS PAINT as an accessory to match the colour of all paintable fastening elements. In this context, the paste systems for the tinting of the universal colour as well as the coloured top coating of the membrane come from our sister company, Dörken Coatings GmbH & Co. KG. In this manner, not only a 100% colour match can be ensured. Furthermore, the special quality of the paste systems ensures that the selected colour is highly resistant to UV and aging, so that there is no fading of the sheet, even after years.
The self-adhesive zones integrated on both edges of the membrane ensure that the DELTA®-FASSADE COLOR PLUS facade membranes are wind-tightly bonded to one another; for the bonding of vertical membrane joints, the membrane manufacturer supplies a highly transparent, permanently UV-resistant film carrier tape. In the area of window and door connections, the membrane was led to the element frame and glued there in a windproof manner. Depending on the feature of the connection surfaces, adhesive tapes or permanently elastic cartridge adhesive may be used for this purpose. More complex connections - such as for example in window corners - and penetrations for installations were additionally sealed with the paste-like functional coating DELTA®-LIQUIXX and then colour-matched with the universal dispersion paint DELTA®-FAS PAINT In all connection work, the potential optical influencing factor had to be considered, i.e. only the use of transparent or paintable components were allowed in all areas which were visible through the facade cladding.
The result of this care was clearly shown after the subsequent assembly of the facade elements and the scaffolding dismantling. Depending on the point of view and the lighting conditions, the facade impresses with its spectacular variety of optical effects. During the passage from diffuse light to direct sunlight, the appearance changes as well as when the observer's perspective changes. In any case, the client and the facade builder are extremely satisfied with the result and are sure that they have made the right choice when it comes to materials.
