PERFORMANCE OF WEATHER EXPOSED DECKING DURABILITY
All decking timbers stocked by Calco Trusses & Timbers are naturally durable and have Class 1 and 2 durability ratings. Timber durability ratings relate to heartwood deterioration due to decay (fungal) or termites and are rated on in ground contact conditions. The sapwood of any species is classified as non durable. Being durable does not stop timber against rapid wetting and drying, and the resulting expansion/shrinkage. Different species also react differently under these conditions and we recommend you seek our advice when choosing wide board decking.
DECKING MOVEMENT IN SERVICE
Decking timber is kiln dried to under 18% moisture content and when exposed to weather are subjected to alternate periods of wetting and drying which can cause:
1.Board expansion or board shrinkage
2.Splitting of boards – particularly at board ends and nail fixing points
3.Surface checking or face splitting
4.Distortion or twisting
TIMBER PROTECTION - DECKING FINISHES AND TREATMENTS
Calco Trusses & Timbers recommend that all external timbers should be finished with an exterior grade finish to reduce the effect of rapid wetting and drying of the decking (and other exterior) timbers.
Calco Trusses & Timbers stock a wide range of decking timbers in a range of versatile sizes. Those sizes are generally 70x19mm, 90x19mm and 140x19mm. We also stock Spotted Gum wharf decking in 140x32mm.
It should be noted that wide boards are more reactive to swelling or shrinking than narrow boards and should be a definite consideration in large deck areas.
ModWood decking is stylish, versatile and easy to install. Whether you have a deck, entertaining platform or pool and spa area, ModWood adds definite style and sophistication which is long wearing, safe and eco-friendly. Our decking is safe for children as it is splinter free., Due to the fact that decks around swimming pool areas often have restricted ventilation and are of course potentially high moisture areas, when installing a deck around a swimming pool we recommend that ModWood solid section decking is used.
ModWood decking comes in a range of colours. The Natural Grain Collection is available only in the solid decking board. More Information
