- To ensure an optimum support of the GU frame for projecting installation, fasten it using the GU 1K installation adhesive and GU anchor for projecting installation.
Processing information
The GU frame for projecting installation is a powerful problem solver for modern construction and energetic renovation. Windows and balcony-doors can no longer be fixed directly through the frame to the masonry in the case of multiple-layer outer walls that are formed by fixing a exterior insulation finishing system (EIFS). Conventional installation was done in the EIFS i.e. in a nonstructural material. Supporting structures are therefore essential for the fixing frame of structural elements. The GU frame for projecting installation performs its function particularly well thanks to its impressive features. It is very efficient to work with and has been tested for burglary protection to EN 1627 up to resistance class RC 2. In addition, the rectangular cross-section of the frame provides flexibility: it can be installed in two positions, so that, for example, the installation depth can vary between 90 and 120 millimetres.
Installation – step 1
During installation, the GU frame for projecting installation fixed under the component is first cut to the length of the dimensions of the window. The dimension here is calculated from the left outer edge of the frame formed by the frame to the right outside edge. The horizontal lower element is therefore measured along the full length, and the upper frame is also measured in the same way. The vertical frames are fitted to the sides of the window between these horizontal elements.
Installation – step 2
After cutting, the GU-1K installation adhesive is applied bead- and serpentine-like to the frame for projecting installation and then bonded to the surrounding masonry. In doing so the abutting edges must be glued airtight. The special processing instructions of the products used and the surface treatment must be observed.
Installation – step 3
Then the bonded GU frame for frame for projecting installation is also fixed to the GU anchor for projecting installation. At least three anchors per frame must be installed and the positions on the frame where they must be fixed is described in the graphic on the opposite side. The maximum distances from the outer edges of the GU frame for projecting installation to the first screw connection is 150 millimetres with a maximum of 700 millimetres between the fixing points. Carrying out the screw connection according to these specifications provides the necessary edge spacing for fixing stability on all sides.
Installation – step 4
The structural elements are installed perpendicularly and flush with the GU frame for projecting installation. Fixing the lower shims is not required for an exact plumbing of the frame. Installation of the window is carried out with self-cutting frame anchor screws (diameter 7.5 mm). When selecting the screw length, it is essential to ensure that there is a minimum engagement depth of 60 millimetres in the GU frame for projecting installation. In addition, the separate test certificate and the corresponding installation instructions must be observed with anti-burglary versions.
Installation – step 5
The sealing between the structural element and the GU frame for projecting installation is made in the last step. GU gun foam, GU outside window sealing tape, GU joint sealing tape, GU sealing tape BG1 and other sealing products of the GU Group are used here.
Note: During the entire installation process, the "Guidelines for planning and executing the installation of windows and house doors for new constructions and renovations" of the RAL-Gütegemeinschaft Fenster und Haustüren Einbaubeispiele e.V. should be observed.
