Composite decking naturally expands and contracts with temperature changes. Proper installation with recommended gapping allows the boards to adjust without affecting their appearance or performance.
Yes, Trex composite decking expands and contracts with temperature fluctuations, as with most composite materials. To account for this natural movement, it?s essential to leave a gap between boards during installation. The recommended gap is 5mm to 8mm for end-to-end board spacing and 3mm to 5mm between side edges of the boards. These gaps ensure that the decking can expand and contract without causing buckling or warping.
Yes, it is highly water-resistant and ideal for use in coastal areas or poolside. The capped surface prevents moisture absorption, protecting against swelling, rotting, or warping.
Use products like Cutek Extreme CD50 to protect timber from moisture, splitting, and fungal decay. For colour enhancement, choose from the range of Cutek Colourtones.
Millboard composite decking has a BAL-19 rating under the Australian bushfire standards, meaning it can be used in areas that require this level of fire resistance, provided it is installed within a compliant system. The rating indicates that it is suitable for environments prone to ember attacks, radiant heat up to 19 kW/m², and some wind-borne debris without igniting. This makes Millboard a practical option for enhancing fire safety in decking applications.
