ALT F50 SSG modification is designed for semi-structural glazing of building facades. The solution has been developed on the basis of classic ALT F50 post-transom series. Standard posts and transoms of the system with 50 mm visible width are used as the bearing structure.
Primary difference of this facade solution is the absence of wide 50-mm clamping and decorative caps. In their stead narrow clamping profiles are used, which almost invisible from outside, simulating the structural joint.
In this system integrated semi-structural windows can be built-in into the facade structure as window blocks.
Use of available thermal inserts and gaskets allows installation of glass units 28 - 50 mm thick manufactured in compliance with requirements imposed on structural glazing. Glazing, as well as installation of window blocks is done form outside of the building.
Primary advantage of ALT F50 SSG is the facilitation of integrated windows installation into the semi-structural facade:
There is no cutting and joining of clamping plate up to 45º. In similar systems an asymmetrical clamping plate is applied across the entire window perimeter; to provide formal resemblance across the entire facade it shall be cut at 45º. In ALT F50 SSG system in all facade areas a symmetrical clamping plate is applied, so there is no necessity to use a clamping plate of another type and cut it at a certain angle.
The window is delivered to the site completely assembled, so installation (and adjustment) of the furniture at the site is not required. In similar systems installation and subsequent adjustment of the furniture is carried out during the installation, not in the shop. Since many installers do not have sufficient qualification and experience in structure assembly, there are good chances that some error will be made during the installation works. Due to the absence of an adequate frame structure, during the installation of semi-structural facades it was necessary to install the counter part of the furniture on the post (or transom). In ALT F50 SSG system window structures a frame profile is used that provides the assembly of the window block in the shop and send it to the site ready-to-use. Thus the installers do not have to perform works related to the installation and adjustment of furniture, which is unfamiliar to themю
Two types of clamping profiles and decorative element.
