The right hand roof is fully coated and waiting for a ridge.
Thatch roof chimney height.
The left hand roof seems to have more chimney than thatch these four hundred year old almshouses have an abundance of eaves chimneys.
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.
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.
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.
This specification makes sure steep roof slopes are cleared.
That are very common in this part of britain.
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.
Ensure the top of the chimney pots are at least 1 8 metres above the thatch.
The top of the chimney should be at least 3 ft 0 92 m above the roof surface.
We can also install a solid flue liner system and carry out both cctv surveys and drone surveys.
This topic was discussed at length by experts at a thatch fire safety seminar in.
