Top Swing Opuss


  Spilka Opus hinges with their unique construction make it possible to turn the window fully inside, thus making the maintenance of window very convenient and simple. The main feature of Spilka Opus hinges is that they are mounted between the frame and sash and placed in a groove in the side of the window. Because of that, hinges are “hidden” and almost invisible from the

external side and not affecting the exterior, which can be very useful. It is possible to turn window by 180°, making cleaning this type of window easy and more secure.

These windows can be manufactured from wood or a combination of wood and aluminium where aluminium covers the outer part of the frame and sash.

Sound-proof glass ensures excellent sound isolation and effectively drowns out any noise.




Sun-protection glass absorbs the energy of sunlight and reflects it back. Due to its shielding material, the glass will ensure that sunlight will not have as much of an effect on the temperature of the room and will limit the extent to which the room is heated from sunlight.



Self-cleaning glass glass with a self-cleaning coating that does not need to be cleaned as often and is more resistant to mechanical damage. The glass functions due to two natural components – the sun and the rain. The UV light of the sun dissolves dirt and makes them easier to clean. The rain washes away what is left of the dissolved dirt from the glass.




Safety glass is five times tougher than ordinary glass. By equipping windows or doors with tempered glass, building safety is increased. If broken, the glass crumbles into small pieces that are less hazardous.
