Patch fitting means frameless glass elements in both interior and exterior parts of a building. The patch fitting glass door assemblies are made of toughened glass with top and bottom fittings. Top fitting is for fixing the frameless glass panel to the roof while bottom fitting is for attaching it to the floor. The frameless glass element has holes for fixing the patch fitting hardware. Patch fitting doors require hardware such as top patch fitting, bottom patch fitting, patch fitting clamps and patch fitting locks. The spaces between successive panels of frameless glass are filled with silicon sealants to provide protection against friction. The hardware used in fixing patch fitting panels are usually made of brass or 316 stainless steel.
The glass patch fittings can be moulded into a plethora of designs as per the architecture of the building. Patch fitting doors and partitions score high in terms of durability and strength apart from superior aesthetics. This is the reason why they are widely used in offices as modern glass doors and partitions.
