Improving Energy Efficiency for Sash Windows in Bristol

Original timber sash windows can be warmer, quieter and easier to use with a few targeted upgrades. This site explains proven methods that keep the period look while improving day-to-day comfort.

Slimline Double Glazing

Where frames are in sound condition, new timber sashes with slimline double glazing can be fitted while the original boxes stay in place. Sightlines and glazing bars remain true to the period style, yet heat loss and external noise drop significantly.

Draught Proofing

Discrete brush seals fitted into beads and meeting rails block cold air movement while both sashes still slide freely. The result is a calmer room, fewer rattles and a noticeable lift in comfort through the colder months.

Keep the Look, Improve the Comfort

Many Bristol homes sit in conservation areas. Work that respects timber profiles, glazing bar layout and vertical sliding action can meet guidance while bringing efficiency up to modern expectations. A balanced approach avoids unnecessary replacement and protects the character that buyers value.
