The Installation and Restoration Process

2. Lumber Preparation and Treatment

The hallmark of a professional installation is the “finger-light” operation of the sash. If the weights are too light, the window will not remain open; if they are too heavy, it will be tough to close. Experts use specialized scales to weigh the glazed sash and then adjust the internal weights appropriately.
4. Incorporating Draught-Proofing Systems
One of the main complaints relating to standard sash windows is their tendency to rattle and let in cold air. Professional fitters incorporate brush stacks and covert seals into the meeting rails and staff beads. This substantially minimizes sound pollution and heat loss without changing the window's appearance.
