Crisp, white UPVC bay window with replica top lights, hand crafted from the original design. The bay is now much more usable with opening top lights housing trickle vents to help ventilate the room. The frames provide ultimate security being fully steel reinforced, with a high security 8 point locking system and is now internally glazed. It has achieved the best of both worlds, as it is still a beautiful traditional bay retaining its period features but is energy efficient, secure and functional.
