Thatch Roof Chimney Height

We can also install a solid flue liner system and carry out both cctv surveys and drone surveys.

Thatch roof chimney height.

Ensure the top of the chimney pots are at least 1 8 metres above 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. This topic was discussed at length by experts at a thatch fire safety seminar in. We install twin wall insulated flue systems to allow flue to pass any combustible materials safely and terminate at the regulation height of 1 8 metres above thatched ridge.

For gas vents or a type l vent this distance above the roof surface must be at least 2 ft 0 61m. Chimney heights the height of a chimney is usually the main issue with thatch properties as a large proportion of them are also listed buildings. 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 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 left hand roof seems to have more chimney than thatch these four hundred year old almshouses have an abundance of eaves chimneys. This specification makes sure steep roof slopes are cleared. The top of the chimney should be at least 3 ft 0 92 m above the roof surface. The current building regulations state that the top of the chimney pot should achieve 1 83m above the thatch ridge.
