Wall form units and systems

A wall form system, comprising:

• a core comprising pourable, curable construction material;
• a plurality of panels sheathing the core, wherein the plurality of panels comprises at least two wall form units adapted for interlocking and wherein each wall form unit comprises a first panel and a second panel in predetermined relation, thereby forming a hollow between the first and second panels for receiving the construction material;
• and
• at least one tie assembly comprising a spacer member for maintaining the first panels and the second panels in predetermined relation,
• wherein both the first panels and the second panels are rigid and adapted to retain the construction material,
• the first panel comprises a thermally insulating material, and
• the second panel comprises a thermally conducting material.

A process of erecting a building structure, comprising:

• i) arranging a first panel and a second panel of a plurality of Insulating Concrete Form (ICF) units in predetermined relation for defining a wall section, such that the first and second panels are spaced apart to form a hollow between them,
• ii) connecting at least one tie assembly comprising a spacer member for maintaining the first and second panels in predetermined relation,
• iii) introducing a pourable, curable construction material into the hollow, and
• iv) curing the pourable, curable construction material,
• wherein both the first panel and the second panel are rigid and adapted to retain the construction material,
• the first panel comprises a thermally insulating material, and
• the second panel comprises a thermally conducting material.
