What is the recommended spacing for installing Polyboard horizontally?
In order to maximize impact resistance against forklift ramming, Polyboard opts for toughness rather than rigidity, and it therefore requires more supports when installed for a load-carrying application. For 12mm, 16mm and 18mm sheets, a minimum of 12″ centers is recommended to reduce deflection. However, the sheets will become sturdy and secure once they are nailed or screwed onto a frame or a solid ground.
