How to choose the right type of frames?

The choice of frames should be commensurate with the particularities, the external conditions of the building and the type of construction. You should pay attention when choosing the appropriate system, depending on the opening of the frame. For example, a “light” system has greater openness restrictions than a “heavy” system that can provide more applications of solutions.
The main types of frames we can choose are as follows: sliding and opening frames in various versions.

Casement Windows
Casement Window offers effective thermal and sound insulation, seal against the air and water leakage, but it is not possible to cover large openings, ie more than 1.70m usually, even with a double balcony door. They also provide greater security due to the perimeter mechanism and additionally, they provide all the opening while at the same time they require an interior space to open the balcony door

Types of Casement Windows:

Opening inwards with or without tilt function
Opening outwards
Top hung windows (that open outwardly from the bottom)
Vertical or horizontal pivot windows
Combination of sliding and hinged window with deflection mechanism

Sliding windows

Space economy is the main advantage of sliding windows. They are mostly used in building constructions – where space economy is required. Sliding windows are the special feature of Greek market used widely in the constructions in the 1970s and 80s. Current series of sliding windows are adapted to the market requirements and offer the best insulation possible, as well as thermal insulation solutions. They need less space to operate and accept glass, insect screen and shutters or external rolling shutters They can be hidden into the wall (using the whole range of opening) and externally to the wall. They may also be a double leaf door joined in the center of the aperture, or horizontal sliding windows standing next to each other on separate sliding tracks, and multi leaf door offering a similar function.

Types of sliding windows:

Horizontal sliding windows: multiple sliding windows stand next to each other on separate sliding tracks leaving open only the half of the window

Corner windows: Constructions in which two sliding windows make a right angle (90o) and are locked at their connection point in the corner

Meeting stile windows: two sliding windows stand on the same sliding track and are locked at their connection point in the middle

Pocket windows: Usually, one or two sliding windows which when opened are hidden into to the wall.
