8. What composite decking boards are best?
How do you know if hollow or solid composite decking boards are right for you? As well as thinking about budget and style, make sure you get value for money by looking at the structural properties and quality of the boards you are considering. Both can handle considerable weight for every day use.

Hollow boards have the advantage of being lighter than solid boards. However, if you are considering putting weighty objects on your decking, like a hot tub or furniture, solid boards would offer more stability. Solid decking can also be more suitable for sunken decking areas or areas with limited air flow. This is because you can adjust the gap between solid boards to 5mm, which will allow for better air circulation than the 2mm gap required between hollow boards.
