Yes, building a subframe is typically necessary when installing a loft boarding system. The subframe provides a stable base for the loft boards and helps distribute the weight evenly across the joists, preventing damage to the ceiling below. It also creates an air gap between the insulation and the boards, which helps to maintain proper ventilation and prevent moisture buildup. Without a subframe, the weight of the boards and any items stored on them could compress the insulation and cause damage to the ceiling below.
