Bay windows are a prominent feature of many British period properties. Installing secondary glazing in a bay requires careful planning to accommodate the angled or curved configuration — but the results are outstanding.
Bay windows come in squared, angled (30° or 45°) and curved (bow window) configurations. Each requires specific secondary glazing specification.
Most common in Victorian and Edwardian properties — central flat window with angled returns. Secondary glazing installed as three separate units (or a single continuous frame) with frames cut and joined at the appropriate angle for a seamless appearance.
Bow windows require bespoke curved aluminium frames. Our bespoke manufacturing service produces frames with any curve radius to match the exact profile of the original window.
For bay windows we often recommend a timber subframe to provide a clean finish, incorporate a bench seat, and act as a thermal barrier between the aluminium frame and the cold bay structure.
Bay windows are often the coldest and draughtiest part of a period property. Secondary glazing delivers: up to 65% heat loss reduction, elimination of bay window draughts, up to 80% noise reduction for road-facing bays.
