Component anchoring with a system without thermal bridges

Secure attachment of add-on elements to insulated building envelopes

Mounting something safely and without thermal bridges on to insulated building envelopes is now easy: the latest product from GLASSLINE, the modular FIX•N SLIDE outside system, revolutionises component assembly in the ETICS sector. It ensures not only the secure attachment of add-on elements to insulated building envelopes, but also simultaneously minimises thermal bridges in new constructions and retrofitting.

Adelsheim, 6th February 2018. Due to the requirements of legislators, such as the Energy Saving Act (EnEG) and the Energy Conservation Ordinance (EnEV), the envelopes of heated buildings are provided with increasingly thick layers of insulation. Due to structural-physical properties, the insulation is most often installed on the outside of components of the building envelope. Regardless of new or existing thermal insulation systems, the attachment of insulated exterior walls of add-on elements such as chimneys, Venetian blinds, canopies, air conditioning units, or awnings is always a challenge, because thermal bridges need to be reduced and the elements must simultaneously be securely anchored. The usually large dead weight of the elements and the variable loads such as wind or snow place huge demands on the attachment system.

So how does a leading manufacturer and supplier of products in the field of frameless glass architecture come to address this issue? "We are closer to the ETICS issue as it seems," explains Thomas Utsch, Managing Director of GLASSLINE. "Customers who have obtained a CANOPY cloud all-glass canopy or a BALARDO balustrade system from us were looking for a suitable system that would securely hold these loads even on a thermally insulated façade. This was a challenge for our developer's workshop that they overcame with FIX•N SLIDE.“ According to GLASSLINE, FIX•N SLIDE offers everything that constitutes a typical GLASSLINE product. It is modularly constructed, highly flexible in terms of its applications and thus remarkably simple and highly effective in the planning and assembly stages. With only a few components and differently sized insulating elements, each insulation thickness can be bridged following thermal and static testing up to 315 mm. The thermal properties of FIX•N SLIDE fulfil the criteria of the EnEV 2016.

"For FIX•N SLIDE to satisfy every situation in the vertical, horizontal and overhead areas, the system serves as a rail for linear installation and as a system component with adaptor plates for point-to-point attachment," explains Managing Director Helge Schönig.

The design of the rails is conceived for use in all-glass canopies, conservatories or balustrade elements in attic, balcony and roof areas, among other things. The main component is the cross-application aluminium rail for pre-assembly and connection to the substructure. During installation, the bearing forces can be adapted to the local conditions through a variable arrangement and number of bore holes. In the second step, bearing elements with high-tensile threaded rods are used that can be flexibly adapted to the attachment points of the add-on elements through adjustment. After insertion of the insulating elements that are appropriately drilled for introduction of the threaded rods, the add-on element can then be precisely mounted. To cover the widest possible range of applications, GLASSLINE delivers the glass panes in lengths of up to 3,000 mm and in five system widths. Aluminium plastering/connecting plates are optionally available.

For point-to-point connection, such as awnings, Venetian blinds, stainless steel chimneys, advertising structures or photovoltaic modules, GLASSLINE has developed its FIX•N SLIDE as a firmly defined system component with an adaptor plate. The construction and assembly are almost identical to the design of the rails. Only the adaptor plate and threaded sockets for its attachment constitute a difference. The component with adaptor plate is also available in five system widths, the length, however, is set at 200 mm. The component can also be used with or without on-site adaptor plates. GLASSLINE optionally offers corresponding stainless steel adaptor plates.

Both systems guarantee with their metal supporting components a structural residual load-bearing capacity even in the case of malfunction, such as due to fire.

"With FIX•N SLIDE, the possibilities are far from exhausted. After insulated exterior walls, we will concentrate in the next steps on applications for thermal panel façades and interior insulated walls," speaks Managing Director Thomas Utsch about the future.
