Friction hinges

(easy clean and egress)

Friction hinges are very popular for flush windows and are very practical as they have a natural stopping mechanism from the sash window being pushed by wind. They can withstand up to 10,000 cycles.

Easy clean

Easy clean hinges are a perfect solution for cleaning as they allow sash windows to slide, for easy reach to clean windows from the inside.


Egress aka Fire escape hinges allow casement windows to open to a full 90 degree for emergency exit to comply with the British Standard BS5588 Part 1:1990 and building regulations approved document B for fire escape windows. Once the sash window is closed it automatically resets to the fire escape mode.

Butt hinges

Butt hinges pivot the casement away from the reame.

When mounting doors, you can use a butt hinge to link both the door and the jamb. It usually consisted of two leaves, one attached to the door and one attached to the jamb.”

Both types are made of stainless steel for enhanced corrosion resistance.
