- What thermal performance does fixed picture windows achieve in Harpenden?
- Energy-efficient fixed picture windows installed across Harpenden, Hertfordshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- How big can a fixed picture window be?
- Up to 2.7m tall and roughly 3.5m² per panel with our standard glass. Larger sizes are possible using structural glass with additional lifting equipment on site — we survey and quote separately for anything over that.
- Can you fit one above bifold doors?
- Yes — a fixed head light above a bifold or slider is our most common configuration for full-height rear extensions. We coordinate the head detail, structural opening and colour match as one order.
- Do fixed windows meet Building Regs for ventilation?
- A fixed window on its own doesn't provide ventilation, so Approved Document F requires another means of purge ventilation in the room. On a rear extension this is usually satisfied by the adjacent bifold or slider. We check the room-by-room ventilation plan at survey.
