1. Thermal Performance and Draught-Proofing

2. Acoustic Insulation
Professional fitters can encourage on acoustic glass or various thicknesses of panes to minimize street noise-- a common requirement for city-dwellers in period homes.

Signs You Need a Professional Fitter vs. Basic Repair
| Sign | Potential Cause | Professional Requirement |
|---|---|---|
| Rattling in the wind | Worn personnel beads or absence of seals | Fitting of draught-proofing system |
| Sash will not keep up | Damaged cable or inaccurate weights | Replacement of cords and re-balancing |
| Noticeable rot in the sill | Water ingress | Partial or full frame replacement |
| Condensed glass | Blown seal in double glazing | Replacement of glazing system |
Conservation Areas and Planning Permission
