- the discrete solution-
Windows with Spilka Opus™ hinges are opened by means of a handle on the lower part of the sash and can be closed and also secured in a ventilation position via an espagnolette locking system. Spilka Opus™ hinges incorporate a safety lock as a standard, this limits the initial opening of the window to a maximum 80mm at the bottom of the sash.
For cleaning purposes, the window can be turned 180º, which will engage the safety device and hold the sash securely. The sash does not intrude into the room, curtains and plants on the window sill are not disturbed.
Spilka Opus™ is specifically made to maintain a flush outside surface. This makes it very well suited for production of windows with aluminium cladding.
Outward opening windows have a weather performance advantage as the sash is made tighter against the weather gasket in the frame by increased wind pressure.
Consistent and precise production of our hinges and components, with sealed, lubricated rivets on the hinges, allow for a long operational life for Opus-hinged windows. The sash is securely balanced on the hinge and is easy to operate in all positions including fully reversing for cleaning.
