Traditional timber sash windows work seamlessly with a weight system and a cord system. The cord that runs across the hidden pulley connects the weight to the window frame. The weight acts as a counterweight to the sash window, providing enough resistance to ensure a smooth opening.

How do they work?
Two lead weights are attached to the sash cord. They balance each sash as it slides up or down.
The weight pockets are made from timber linings. They sit on both sides of your window. These pockets hold the lead weights.
Sash Cord The sash cord holds the weights to balance your sash slide. To maintain the correct weight, the sash cord runs across a pulley wheel.
The top Rail is the highest horizontal frame in the window. Meeting Rails are horizontal framings which join the sashes at the middle.
A pulley wheel sits at the top end of a pulley liner that allows the sash chords to pass over it while still maintaining balance.
A Paring bead, a long and narrow seal, is what allows the lower and higher sashes to pass through and holds the upper sash in its place.
Timber Linings are hollow sections which house the weights and make up the box frame’s case.
