Most rain screen cladding manufacturers do not recommend their cladding material be taken to grade level or below grade.  Also, rain screen wall systems need to be weeped above grade level.  So how best to fill the gap at the foundation wall to allow for continuous insulation?  T-Clear Corporation WallGuard fills the gap and allows for continuous foundation insulation above and below grade.

Wallguard(R) is also the ideal solution for slab on grade applications to maintain continuous insulation requirements and ensure energy efficient design and construction.

Wallguard(R) is manufactured using DuPont Styrofoam extruded polystyrene insulation, with a factory-applied 5/16″ latex modified concrete coating.  Panels are 2′ x 4′ with tongue-and-groove edges on the 4′ length.
