A subframe is the structure that sits beneath your deck, keeping it supported and providing the base that your decking boards are attached to. Plas-Pro is Millboard’s premium 100% recycled subframe material and can be used alone or as part of our DuoSpan landscaping subframe system. This all-weather, durable and flexible material is a non-rotting alternative to timber and is perfectly suited to spaces exposed to damp, such as jetties, pools, roof terraces and boardwalks.
