Subframe Options

Composite Decking Needs A Solid Subframe

Various subframes can be used when installing Assured Composite decking. Be sure that you choose the right subframe taking into account the foundation and the space underneath deck boards for ventilation (minimum 35mm).​

Assured Adjustable Pedestal Supports

Assured Adjustable Pedestal Supports are used in areas where you require the joists raising off the surface. These are for concrete or solid foundations and can be used with timber, plastic, metal or solid composite joists to support the deck.

Assured Hollow Composite Joists

Assured Hollow Composite Joists are used where a concrete foundation is in place. The composite joists can be laid and fixed directly to the foundation or if solid can be used with our Assured Adjustable Pedestals for a raised decking area.​​​

Assured Plastic Joists & Posts

Our recycled Assured plastic joists and posts can be used on hard or soft foundations and are ideal in situations where the ground is uneven or you require a high raised decking area.​​​

Timber Joists & Posts

Like Assured plastic Joists and posts these can be used on hard or soft foundations and are ideal in situations where the ground is uneven or you require a high raised decking area.​
