We are finding that our tower is becoming uncomfortably hot during the summer months.

As a sandstone tower, it tends to retain the warmth sometimes days after the heat outside has subsided. Similarly, in winter, the walls remain very cold even after a cold snap.

We have next-to-no ventilation in our tower. There is a large, partitioned, stained glass window (age unsure, but I'm guessing over 150 years old) on one wall. Opposite this is an arch shaped glass window with a circular opening which opens in to the main body of the church.

There's holes in the ceiling (for sound) and a trap door leading to a clock chamber.

The question is - does anyone have any experience of installing ventilation in a tower like this, and have knowledge of the steps required re. faculties etc?

I've considered putting vents in the floor, but I'm not convinced that would help much. The only thing I can think of is to put some kind of vent(s) on the stained glass windows - perhaps even a hinge.

Can anyone offer advice?
