Thatch Roof Chimney Height

This topic was discussed at length by experts at a thatch fire safety seminar in.

Thatch roof chimney height.

The height requirement is thought to allow for any sparks embers to preferably die out before they exit the chimney or be ejected away from the thatch. The reason for 1 8m is a topic for discussion as although it is in building regulations no one knows exactly why that height best guess has been that it is the height of a person. The top of the chimney should be at least 3 ft 0 92 m above the roof surface. Vertical blue line along the left side of the chimney in our photo.

We can also install a solid flue liner system and carry out both cctv surveys and drone surveys. The current building regulations state that the top of the chimney pot should achieve 1 83m above the thatch ridge. For gas vents or a type l vent this distance above the roof surface must be at least 2 ft 0 61m. That are very common in this part of britain.

This specification makes sure steep roof slopes are cleared. For small 440mm square two brick stack chimneys there must be at least a 40mm gap from the outer face of the brickwork to the thatch material this can be done by constructing a non combustible shield away from the face of the chimney before re thatching takes place. The right hand roof is fully coated and waiting for a ridge. Ensure the top of the chimney pots are at least 1 8 metres above the thatch.
