ALT F50 HL “Horizontal Line” system is still another variety of post-transom facade ALTF50, where one of directions of the glass unit clamp is distinguished from outside – horizontal or vertical. This is achieved by applying of various camouflaging plates (e.g., elliptical F50.0507 or semi-circular F50.0505) highlighting one direction, thus providing the building with some additional volume, either horizontal or vertical. Moreover, for lines going in the other direction, glass unit fixing profiles are replaced with a decorative joint gasket, or the space between glass units is filled with joint silicone sealant resistant to various weather exposures.
Besides, instead of standard clamping and decorative plates with visible width equaling to 50 mm, this system allows using clamping profiles F50.1601 or F50.1602 with visible width 38 mm. This being the case of another modification of post-transom system - ALTF38 HL “Horizontal Line 38 mm”.
Like in other versions of ALTF50 facade, constructions of “Horizontal Line” type can use hinged windows of “concealed leaf” type without altering the facade appearance.
Use of available thermal inserts and gaskets allows installation of glass units 22 - 38 mm thick manufactured in compliance with requirements imposed for structural glazing. Glazing, as well as installation of window blocks, is done form outside of the building.
ALT F50 HL has several principle advantages in comparison with similar systems available on the market:
Vertical space between glass units in ALT F50 HL system may be filled with a special gasket installed into thermal bridge groove, instead of joint structural silicone.
In horizontal direction a clamping plate with decorative cap from the standard post-transom system is applied (with visible width 50 mm), or clamping plate form ALT F50 SSG (with visible width 38 mm).
