Architects or home owners considering having thatched roofs will need technical input about the structure, the type of thatch, the pitch and configuration of the roof, fire prevention and the use of the extra upper living space created by using thatch, says Cheryl Neave of the Building Centre.

“Recognising this, Lucas Quality Thatchers has established its own consultancy, with designers and engineers who will work hand in hand with others.”

A big deterrent to using thatch is the fear of fire, but Neave says Lucas Thatchers has taken every measure to lessen the risk with up to date technology.

“The first step to eliminate the fire hazard was to replace the traditional stitching twine, which can be a fire conductor, with galvanised or stainless steel wire. Lucas then developed its sophisticated roof drencher system hidden in the roof capping. In the event of fire, the system will flood the affected section with water so thoroughly that the flames are put out.

“The drenchers are linked to internal smoke detectors and external temperature sensors, and the thatch roof can be given a state of the art chemical treatment that greatly extends its life.

“Complementing these provisions, Lucas can install ceramic blankets that are embedded in the thatch and prevent a fire from spreading by effectively denying it oxygen. This system, now used worldwide, has completely revolutionised thatch roofing.”

Lucas has branched out internationally from residential housing into theme parks, game lodges and a variety of hospitality venues, and also instals spaansriet ceilings and partitions, wood claddings, wood decking and stone accessories.
