2. Acoustic Insulation
Expert fitters can encourage on acoustic glass or different densities of panes to lower street noise-- a typical requirement for city-dwellers in period homes.

Indications You Need a Professional Fitter vs. Basic Repair
| Sign | Prospective Cause | Expert Requirement |
|---|---|---|
| Rattling in the wind | Used staff beads or lack of seals | Fitting of draught-proofing system |
| Sash will not keep up | Damaged cable or incorrect weights | Replacement of cords and re-balancing |
| Visible rot in the sill | Water ingress | Partial or full frame replacement |
| Condensed glass | Blown seal in double glazing | Replacement of glazing system |
