The most affordable option (applicable to free draining, relatively dry conditions only) is to use treated softwood. Although softwood substructure will become slimy/moldy easily over time, this is normally acceptable as it is not seen. We can also provide a composite substructure profile which is useful in wet conditions or areas with low air circulation. In particularly damp conditions where the deck is over 1 meter off the ground, we recommend the use of galvanized steel box section beams / hard wood structure or other stronger structure. 

If it gets marked or damaged, then the scratch can be softened and blended back into the deck using either Danish or Tung Oil. Please see our                                                    for more details.

Forestar product is of unique and higher-cost formulation, and the best fire resistant rate we can carry is the B1. Unlike wood, it is not easily to be ignited due to its solid product with no air pockets inside, but once it catch fire, if the fire source is removed from, it will self-extinguish very quickly and will not drip molten material like plastic does.

No. Just normal tools are enough, special woodworking equipment is not required.

Forestar product is wood plastic composites, made from a unique blend of recycled wood powder and plastics, combines with highly advanced manufacturing process. Forestar product is a special combination of approximately 60% hardwood fibers, almost 30% polypropylene, and the rest 10% contains high quality pigments and some other additives such as UV stability, mildew and fire resistance.

Forestar products has an appearance that is very similar to wood and works as perfect alternative to wood, but not substitute.

No. Please do not use any glue to fasten or seal between Forestar boards. This application will damage the performance of plank, such as its drainage system and natural expansion.
