This guide explains the features and benefits of the NUDURA system. It includes DURALOK, which securely locks forms into place; DURAFOLD, which allows the form line up to be easily assembled and shipped flat; and the patented 4-way reversible system, which reduces waste and helps speed the building process. NUDURA is the largest ICF form size on the market allowing 1.115m2 of wall area to be installed with a single form. This literature contains illustrations and measurements plus suggestions how to maximise the benefits of NUDURAs ICF building system. It also explains the newly launched retrofit system, which is a cost effective way of insulating foundation walls, non-insulated slabs and the inner/outer surface of exterior walls. The full range of NUDURA accessories is also shown.
