Forestar product can adapt to various weather conditions. It will shrink in hot and expand in cold when installed. We recommend to put boards in the working spot 48 hrs before installation so as to make it’s adaptation to the weather.

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.

Yes, but not required. Because Forestar product is very low maintenance product and not required to painting or staining. Stains and paint are just adhere to the surface of our boards, and you may need to re-painting them periodically just like wood does if you still want to stain.

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.

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. 

You need to pre-drill in just a few instances. For example, when you install the deck, you need do drill in the deck covering area for adapting plastic expansion bolt.
