4. Hardware Overhaul: Pulleys are cleaned and oiled (or changed if necessary). Cables are changed with high-tenacity nylon-core ropes.
5. Rebalancing: The weights inside package frame are adapted to ensure the window remains open at any height and moves with minimal effort.
6. Draught-Proofing Installation: This is an essential modern upgrade. Discreet brush strips are machined into the wood beads and meeting rails to remove spaces.

Slim-Profile Double Glazing
