Product Description

The key element to the Patented Silca System is the Grate. This is the 400x450x38mm structural component that screws direct to the timber or aluminium deck frame and provides the solid flat surface on which to lay almost any kind of paving.
Features:
a) strengthening ribs and hex cells to spread and transfer load across the decking element and down onto the joist.

b) pre-formed countersunk holes designed to guide the screws into the joist at the correct position. (remember to not overtighten screws as this can damage the countersink)

c) a second row of fixing so grates can be uniformly trimmed to slot in between joists should more height clearance be required. (This requires extra timbers clashed to the side of the joist for the grate to sit on.)

d) free draining design for minimum moisture retention

e) micro flex to absorb any movement within the decking element

f) UV stable

g) manufactured in New Zealand from 100% recycled materials. Green Building Product

h) B1, B2 and E2/AS1

Scope of Use

Silca Grates connect together and are securely fastened directly to timber or aluminium deck joists or direct to pedestal using x6 screws per Grate. This provides a solid, flat, permeable surface on which to install various paving materials such as tiles, natural stone, heavy pavers, artificial turf or porcelain. Silca System enables a free draining finished surface and air circulation beneath, preventing moisture buildup in the substructure and ensuring the longevity of the decking element. Suitable for standard elevated decks or those floating over a membrane. Silca System can be specified on structures within the scope of NZS 3604.
