Since we now manufacture a new injection moulded headpiece, without the traditional positioning lugs, applicators can build their joist framework onto the support units, and lay the timber decking on top.

The adjustable stems still enable a flat deck to be constructed onto a falling roof, with the base plates spreading the load in a safe manner.

The timber is secured using ordinary wood screws fixed directly into the centre of the headpiece, which will not split.

Unlike laying joists onto concrete or metal blocks, or even onto timber itself, by using Wallbarn support pads installers can be sure that there is no risk of damage to the waterproof layer below.

And by creating this suspended system of timber decking using plastic pedestals, the timber does not come into contact with standing water, reducing the chances of rotting.
