The pole selection and truss structure is arguably the most important factor in any thatched roof, followed by the quality of the thatching material used. The application and consistency of the thickness of the thatched roof, is another vital aspect.

The span of the roof truss structure determines the diameter of pole selection. Great care is taken in this regard and weight bearing poles are ordered accordingly (the wider the span the thicker the poles). All pole diameter specifications are written into our quotation.

There are various species of thatching materials available and suitable for roofing. The most popular being Cape Dekriet and Hyperhinia Herta. We use both varieties and are able to advise on the correct application taking the existing climate conditions for each region into consideration.

• thatch thickness is generally 170-200mm. We advise replacing the treated twine by using non-flammable galvanized or stainless steel wire to attach the thatch to the roof structure.
• all poles are treated and SABS approved to meet the Code 475 specification. All trusses, tie beams, king posts and bracing are bolted together using galvanised threaded rods - nut ends can be countersunk and plugged.
• laths are also treated and reasonably straight and clean in accordance to the size.
• timber pole varieties include Poplar, Pine and Gum (Eucalyptus), again taking regional climatic conditions into consideration.
• we highly recommend the installation of the SABS approved Fire Retardant Blanket to all buildings unless instructed to the contrary by the client or architect. The fire blanket also provides a screen against dust and is not visible from the inside of the building.
• a fully automated sprinkler system is available, with a back-up manually operated system. This is provided on request.
• additional opening or non-opening skylight windows can be installed for extra ventilation and light.
• all cement ridges are completed with a water-proofing sealant.

A thatched roof is a wonderful lifestyle investment - providing years of pleasure.

Thatching is eco-friendly and certainly applies to the policy of sustainable development and construction. A thatched home provides wonderful ventilation and insulation.
