• Measuring the aluminium window sill On the preliminary stage of the window sill installment, we recommend to meassure correctly the installation space underneath the window frame. The measurement of the installation space¹ will have to take into account the decrease of 3 mm from the windows sill measured length, which will be compensated by the applied aluminium end caps. In order to determine the optimal width of the window sill that needs to be installed, the distance between the solbanc profile and the edge of the building facade shall be measured. For the renovation projects it’s recommended to maintain a distance value of 30 to 40 mm from the finished facade, respectively in case of new construction projects it’s mandatory to respect the execution details indicated by the design engineer. • Preparation of the installation space Installation of the aluminium window sill is recommended to be carried out on a surface without unevenness. For this, the surface of the installation space on which the aluminium window sill will be mounted is prepared, in order to eliminate all the unevenness appeared after the new construction projects, respectively of the mounting adhesives in case of retrofitting projects. This facilitates the correct assembly and ensures a flatness of the window sill, respectively a better adhesion of the chemicals in the polyurethane foams. • Mounting the aluminium window sill The assembly involves in the first stage the application on the window sill of the following components:
- EPDM gasket on the top of the aluminium window sill, cutted to the required length;
- aluminium side covers type “C” or type “L” (depending on the final destination of the system);
- butyl sealing tape, applied to the corners of the end caps;
- soundproofing tape against the sound from rainfall cutted to the required length.
The second stage involves the application of polyurethane foam applied to the horizontal surface of the installation space, followed by the fixation of the window sill to the solbanc profile to the mounting dimensions, with the help of the self-tapping screws protected by the ABS masking caps.
* 1: In the case of new construction projects, take into consideration the use of aluminum end covers type “C” and compare the measured value to the execution details indicated by the design engineer, so that when the installation of the thermo system is finished it will cover the available 18 mm top edge aluminum end cover type “C”. For the instalation of the aluminum end caps type “L”, in case of facade retrofit projects, it’s mandatory to take into consideration the measurement of the existing installation space from one side of the thermal system to the other. **
