Choosing a window is not as easy as it seems at first glance. When a buyer gets a window estimate on the forum, they are asked to make a choice with several details. For example: type of hardware, profile system, appearance, etc. Often, the manufacturing company has more than one profile system in its assortment and, perhaps, from more than one company. These can be 4-chamber, 3-chamber profile systems or the presence of various color schemes, as well as the use of different design technologies.
Components of a PVC window unit:
1) Frame – the stationary part of the structure. The frame is the base of the entire structure.
2) Sash – the opening part of the window unit. The glazing unit is fixed in the sashes using glazing beads. The hardware is located on it.
3) Glazing bead – fixes the glazing unit and sandwich panels in the PVC structure.
4) Mullion – divides the frames into contours, in which a sash can be provided.
5) Accessories – a set of auxiliary elements (flashings, window sills, canopies, hardware elements, etc.)
6) Sandwich panel – the opaque part of the window.
The following types of windows are distinguished (depending on hardware):
1) Tilt windows – open from the top. They are installed in basements, where casement windows can be dangerous, where open sashes interfere. These windows should be easily accessible for maintenance and cleaning both outside and inside.
2) Tilt-and-turn and turn windows – turn windows can only open in one direction. Tilt-and-turn windows can open by turning inward and tilting.
3) Windows that open in both directions – such a window unit rotates around an axis in both planes (vertical and horizontal). Such windows are produced only at high-tech window manufacturing plants, as has been repeatedly written on plastic window forums. These windows are suitable for large glazing units. If you have chosen this window, make sure that it can be fixed in different positions.
4) Multi-sash windows. We recommend choosing a sash ratio of 3:5. This ratio is considered the golden mean. And it is the most popular among people.
5) Fixed windows – it is possible to lock one of the sashes to prevent opening.
