- 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.
