Heveatech engineered hardwood decking joists are manufactured from discarded rubber tree timber. They are designed for use as a subframe for Heveatech decking boards.
They are extremely durable, making them particularly suited to the often harsh and variable European climate. The timbers are offered with a 15-year warranty against contamination and decay and a lifetime warranty against termite infestation.
They are supplied from an FSC accredited source – Hevea Brasiliensis (rubber tree) – which has a typical rubber or latex producing lifespan of 25-30 years, after which they have historically been felled and used for firewood, or even discarded. This timber is now used to achieve Heveatech decking.
It is cut into small layers, which are bonded together under extreme compression and finished with a solid veneer. The result is a decking joist and board with a uniform moisture content and 50% less potential expansion and contraction than other hardwoods.
They have a reeded profile, with a warm light teak finish that gives a natural appearance.
Heveatech joists are generally available in 3m and 4m lengths although other requirements can be accommodated on request.
