The fittings system, although largely visible, is responsible for the proper functioning and the protection of the product.

A tight sealing of the joinery, prevents the access of cold air during the cold season and of head during the summer.

TeraGlass fittings use innovative technologies that provide an efficient ventilation of the room without any impact on energy consumption.

Furthermore, being an element that comes often in contact with the user, the most important feature of a handle is resistance over time. Nevertheless, the design and the comfort of operating it are equally important.

The handles used to manufacture TeraGlass products, present all these features.

TeraGlass windows are provided with standard fittings, with a distance of 800 mm between the locking points and a mushroom head fastener with safety lock, but upon request may be manufactured windows using class WK1 and WK2 fittings.
