Timber Homeshave character
Interesting features and later additionsand alterations are easily carried out
Timber Homes blend into the natural environmentwith minimal impact on the surroundings
Almost no damage to the surrounding vegetation.Ideal for environmentally sensitive and steep sites
Why build to a standard?Timber structures that are not built to the standards may collapse
Why build to a standard?Built to the standard, a timber frame home should last centuries
Why build to a standard?Incorrect treatment may result in a timber frame home only lastinga few years
Why build to a standard?Correct treatment will ensure life long durability
Why build to a standard?Incorrect insulation will result in heat in summer and cold in winter.
Why build to a standard?Correct insulation will result in outstanding climate control andsound insulation
Correct InsulationInfrared camera tells the story
Why build to a standard?Incorrectly constructed timber frame homes create a fire risk
Fire Risk Timber performs better than many other building materials in theevent of a fire. It chars and burns at a slower rate and is less likelyto melt or collapse. Correctly built, a timber home comfortably measures up to SouthAfrican fire safety requirements. The charring rate of timber is0.6 mm per minute. This figure is widely accepted internationallyand has been the subject of extensive published research. The charred timber prevents oxygen reaching unburnt timber, thusextending the structural integrity of the burning timber.
Why build to a standard?Correctly built timber frame homes have a great fire rating
Why build to a standard?
Correct Standard – SANS 10-082Timber Frame Construction is not an ABT and timber structures must bebuilt to the SABS standard.

Using sustainable timber Timber is a renewable resource – in sustainableplantations, harvested trees are constantly replenished.
Energy requirements and greenhouse gas emissions Are we really creating carbon pollution?!
Timber is a practical solution to alower carbon footprint Typical Residential Home ( 200m²)
Environmentally friendly
Looking to the futureInternational trends? “Most European countries are strong advocates for the implementation of theKyoto protocol and thus all new buildings in Europe will undergo an energyaudit and be attributed an energy rating, so that buyers have the ability todistinguish energy efficient from energy inefficient buildings. It is estimated thatone-third to one-half of all GHG emissions are attributable to buildingconstruction and operation costs.REF : UK Timber Frame ril2006/20/c9105.html3-Ürge-Vorsatz et al. 2007.

TAKE AWAY? Correctly build timber frame homes have manyexceptional benefits. Timber frame buildings should be built in strictaccordance to the SANS 10-082. The ITC-SA can provide you with a list of industryexperts that can assist in understanding andimplementing standards. Timber frame homes are gaining popularity in SouthAfrica.
FINAL TAKE AWAY?Australia has recently amended their building codesto allow timber structures up to 25 metres tall.Timber frame structures could alleviate SouthAfrica’s housing shortage and poor buildingpractices in a very short space of time by premanufacturing homes and then creatingentrepreneurs to erect them.

The American Institute of Timber Construction, established in 1952, is a non-profit industry association for the structural glued laminated timber industry. Its members design, manufacture, fabricate, assemble, and erect structural timber systems utilizing both sawn and structural glued laminated timber components.
Timber Piling Council The Timber Piling Council provides technical information, and promotes the use of timber piles in the construction industry. The Timber Piling Council is administered by the Southern Pressure Treater’s Association Photograph shows American Airlines Terminal at JFK w
