T2 Treated Framing Timber

T2 Blue framing is treated to resist termites, making it ideal for internal structural applications in residential construction. It¡¯s kiln-dried, stable, and compliant with Australian standards for peace of mind.

H3 External Framing Timber

H3 treated pine is designed for above-ground outdoor use, providing resistance to decay and fungal attack. Perfect for pergolas, fencing, and other exposed exterior structures.

Decking

Available in a range of hardwoods, treated pine and even composite material, our decking is built to handle the harsh Aussie climate. Whether you¡¯re after natural grain or modern finishes, we¡¯ve got options to suit any outdoor space.

Sound Batts

Keep the noise down and the peace in. Our Sound Batts are designed to reduce sound transfer between rooms, making them perfect for home theatres, bedrooms, offices, and shared walls. Available in 430mm and 580mm widths, they fit standard framing and add a layer of acoustic comfort without compromising on thermal performance. A quieter space starts here.
