More on Performance
Within the building industry, building codes set minimum standards for installed product performance. The International Code Council (ICC) develops the standards for decking, including the standard minimum performance measures for decking products that are not constructed from a solid piece of wood cut from a tree. So how does dassoXTR decking and siding rate when it comes to performance? The good news is that, like exotic woods, dassoXTR bamboo performs at incredible levels. However, ICC standards can be difficult to apply when making apples-to-apples comparisons to other bamboo decking or composite decking. This is because oftentimes either suppliers do not test their materials, or a supplier may choose to report the results only as “passing,” where passing is the test’s minimum standard.
In comparing dassoXTR to exotic woods like Ipe – the most popular exotic hardwood used in decking – a fairly apple-to-apples comparison can be made using three standard measures of product performance (independent of the structure on which the deck is being installed). These include:
dassoXTR vs Other Decking Materials
||Western Red Cedar
|| 1,000 psi
|| longitude %
Its high MOE score tells that dassoXTR is very hard to bend and break. The high Janka rating means it’s hard to dent. And its inherent decay and insect resistance make it suitable for outside use. Another performance benefit: dassoXTR (like exotic woods) will not sag or droop between the joists when exposed to heat from the sun. This can be a particular concern with composite decking products, particularly those blended heavily with plastics.
