A2 Rated Pedestals and Rails for Decking FAQs

How does a decking pedestal system support drainage?

A decking pedestal system raises the deck surface above the substrate, allowing water to drain below the boards. This is useful on balconies, terraces and flat roofs where the finished surface needs to remain level while the base below may have falls for drainage.

What are the benefits of A2 fire-rated decking pedestals over plastic pedestals?

Fire rated decking pedestals offer a non-combustible support option for projects where plastic pedestal systems may not meet the required specification. They are especially relevant for high-rise, balcony and terrace applications where material fire performance is a key consideration.

Are aluminium rails used instead of timber joists?

Yes. Aluminium rails can be used as a non-combustible alternative to timber joists in suitable decking pedestal system installations. They provide a coordinated support structure for decking boards and help reduce the risk of rot, warping or moisture damage associated with timber.

What height ranges are available for MetalPad pedestals?

MetalPad pedestals are available in a range of adjustable heights to suit different build-up depths and finished floor levels. The correct height should be selected based on the substrate, drainage falls, decking board type and required finished level.

Can non combustible decking pedestals be used for commercial projects?

Yes. Non combustible decking pedestals can be considered for commercial terraces, high-use external walkways, hospitality areas and residential developments, subject to correct specification, loading requirements and installation guidance.

What installation components are required with A2 rated decking pedestals?

The required components depend on the decking system, substructure design and project layout. IMS can advise on suitable MetalPad pedestals, aluminium rails, connectors and fixing components for external decking installations.
