Do cut ends of NeoTimber® decking subframe materials need treating?
No. NeoTimber® subframe materials do not require treatment on cut ends. Unlike timber, they won’t absorb moisture or degrade when cut. Simply trim to size with standard tools and position fixings correctly. No sealing or painting is needed, keeping installation simple.
How are NeoTimber® decking subframe materials cut?
NeoTimber® composite and plastic subframe components can be cut using standard woodworking tools, with a circular saw recommended for clean, accurate results. The material cuts similarly to timber but without splintering or exposed cores. Measure carefully, support the piece, and use appropriate safety gear.
Are fixings included with NeoTimber® decking subframe systems?
Fixings are not included with NeoTimber® subframe components, allowing you to choose the most suitable option for your installation surface. Stainless-steel screws are recommended for composite and plastic joists, while pedestals require fixings suited to the base below. This ensures a secure installation across different surfaces.
Can NeoTimber® subframes be used on uneven ground?
Yes. NeoTimber® subframe systems can be installed on uneven ground using adjustable pedestals or vertically fixed plastic posts. These enable precise levelling, creating a stable, even base for decking on sloped or irregular surfaces.
Are NeoTimber® subframe materials suitable for ground contact?
Yes. Composite, aluminium, and recycled plastic subframe materials are engineered to resist moisture and rot, making them suitable for direct ground contact. This provides long-lasting durability in conditions where traditional timber frames are more likely to deteriorate.
