Scyon™ Matrix™ cladding
What is it?

An exterior cladding system with a geometric,expressed joint look. Fast and simple to install, Scyon™ Matrix™ cladding is the commercial look without the commercial price tag.

Where do you use it?

In residential and medium-density applications wherever a modern design is required, including external walls in composite construction, upper-storey and ground-level extensions, and internal feature walls.

What are the key benefits?

Simple to install. Instead of needing the steel top hats associated with many commercial systems, Matrix cladding sheets are installed with Scyon™ cavity trim battens. The expressed joint is created easily using a 10mm packer. Sheets are sanded smooth and pre-primed for fast paint application and a high-quality finish.



Design options. Square and rectangular panels with an expressed joint mean a variety of looks can be created, from horizontal and vertical stripes to geometric patterns. Sanded sheets give a flat, smooth finish and digital printing can add even more design options. Matrix cladding’s resistance to cracking, warping and swelling * means it can be painted both dark and light colours. The option ofbrad nailing minimises visual interruption. Matrix™ cladding may be specified for timber-framed or steel-framed structures.



Durability. The Matrix cladding panels are sealed on all sides for durability and stability, and the product has a 10-year product warranty when installed and maintained correctly.



Enhances energy efficiency. When Matrix cladding is used with the right insulation (and in accordance with James Hardie’s Wall System Thermal Performance Total R-Values Technical Supplement), an R-value of up to 3.4 can be achieved for the wall. The ability to use a cavity construction system adds to energy efficiency and helps moisture management.





* When installed and maintained correctly.

FAQ for Scyon™ Matrix™ cladding

Can Scyon™ Matrix™ cladding achieve a vertical, horizontal and off set pattern appearance?

Yes. Please refer to the current Scyon™ Matrix™ cladding Installation Instructions for further details.

Can Matrix™ panels be installed without the Scyon™ Cavity Trim?

No. The Matrix™ panels are sealed around all six sides therefore the Matrix panels require a cavity. Also Matrix™ panels have only been designed and tested when installed onto the Scyon™ Cavity Trim.

Can Scyon™ Matrix™ cladding be fixed with a nail gun?

Yes. C25 16 gauge 304 stainless steel Brad nail may be used with a suitable gun nailer.
Note: High wind area restrictions do apply.
