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.

Forestar product should be fastened by using approved and standard fixing systems. Normally, stainless steel fixings are high recommended.

Forestar products can be ripped only to reduce width. Please be very careful when fastening ripped boards and refer to our Installation Guides.

If Forestar product has been installed as mentioned in the Installation and Maintenance Guide, most of melt off will flow away rather than freeze. However, we recommend to use rock salt or calcium chloride for ice or snow removal. These may only leave white residue, but it can be cleaned easily by mild soap or rinsing with water.

Forestar product can be heated up and bent, but Forestar cannot guarantee the performance of such application, and assumes no responsibility for it. We recommend such kind of design and work should be reviewed and operated by engineer or licensed installer.

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.
