UPVC stands for Unplasticised Poly Vinyl Chloride and is used to make bay frames. Advantages such as UV protection, sound insulation, chemical resistance, impact resistance, and many more are enabled by these apertures. There are many types of UPVC sliding window handles available in the market. Some of them have been discussed here.
Espagnolette hold is the common UPVC window handle. This hold has a spindle at the back which is attached to the locking system of the aperture. There are two variants of espagnolette holds. One is an in-line hold in which the grip of the hold is in-line to the locking point at the center and can turn left or right. The cranked hold where the grip is at some distance from the locking point is another variant. For example, In-line espag chrome UPVC universal window handles of various spindle lengths and polished chrome appearance are available in the market. Cranked espag black aperture holds of these types are also widely available in the market.
Cockspur hold does not have a spindle. In place of a spindle, it has a spur that is present on a wedge. The hold hooks on to the aperture frame. The holds come in left and right-hand varieties. The wedges also come in different sizes. For example, the cockspur aperture holds gold of this type is available in both left and right-hand variants. These are highly adjustable. Another example is the cockspur UPVC aperture hold black available in a universal size.
Tilt and turn
Tilt and turn aperture holds for these apertures also have a spindle-like espag hold but can turn 180 degrees. The hold can have tilt before the turn or turn before the tilt mechanism. For example, tilt and turn white aperture holds of these types with lockable mechanisms are available in the market. There are huge selections available if you want to buy these bay holds. The price depends upon the type of hold, size, material, brand, and other factors.
