The system of drainage openings in the bottom frame of the sliding balcony part, the incline of its surface and special plugs provide removal of precipitations and protection against water penetration.
Various glazing options
Depending on the used fillet and EPDM gasket in the sliding, swinging and fixed parts of the balcony, it is possible to install glass 4 mm, 5 mm, and 6 mm thick.
The end rabbet component is made in the form of a “swallow tail” thus enabling quick adjustment and quick installation of the strike under the lock catch without milling. The meeting profile is easily snapped into the leave and does not lean against the mounting kit.
The system is easily assembled and installed, and does not require expensive processing equipment. In the sliding part of the balcony the frame and leave profile are overcut at 90°. The construction is assembled using self-threading screws. Additional milling is required only to install the lock. Swinging and fixed frame profiles, as well as swinging leaf profile are cut on the cutoff saw at 45° and are tightened together with aluminum embedded corners. All the grooves required for the assembly, and also punching of corner openings are performed with a special pressure die.
Safety and usability
Felt gasket ensures protection against external exposure and prevents leaves rattling. The leaves can be easily removed and replaced, which facilitates the balcony servicing. At the same time special vertical limit stops prevents the leaves from falling out in the event of wind gusts and ensure protection against entry into the premises from outside.
Widespread and inexpensive processing equipment
By the process of ALT100 series profiles we use standard press machines with dies designed to process Provedal series profiles provided that the die clamp is replaced.
