Mr Verandah offers the following information and guidelines to assist you in making the best choice of timber and roofing materials
Selection of timber size
Mr Verandah will determine the size of the timbers required. The maximum structural performance is calculated with strict reference to the Victorian Timber Framing manual and Engineer Design Principles published by the Timber Promotion Council.
Selection of Timber
The lifespan of a timber structure is determined by the type of timber used, the maintenance provided and the degree of exposure to which it is subjected. All outdoor structures should have a paint or stain finish regardless of the timber used or the level of exposure to the weather.
Is a plantation grown timber specifically produced for structural applications that is kiln dried after treatment for increased stability. It has proven to be more durable than Australian hardwoods and popular imported timbers and has been used continuously as a structural timber in Australia for over 40 years.
As with all exposed timbers CCA treated pine must be painted or stained to prevent cracking, shrinkage, or twisting. With proper maintenance it can be expected to last for more than 30 years without significant rotting or termite damage. It comes in a 'microline' semi smooth finish ideal for a paint or stain finish and, it is ideally suited for all exposed or semi-exposed applications.
Is a popular timber that may be successfully used in the structural component of pergolas and decks that are protected from the element. However it is not recommended for use where there is long term exposure to weather due to its moderate durability characteristics.
