WarmFörm™ Slab Forms are remain-in-place, self-shuttering, insulated concrete formwork used to create slab-on-grade foundations that comply with the IRC code for Frost Protected Shallow Foundation applications.
WarmFörm is based on decades of testing and tens of thousands of installed examples in Northern Europe where it is has evolved as the preferred formwork system, as it combines insulation and formwork in one elegant solution. Because the outer face of WarmFörm comes prefinished with a cement render, there is no need to finish the exposed stem wall face after construction, and because the prefabricated elements are made to exact sizes, and there are no stakes to pound making dimensional accuracy of the finished slab is easier to achieve.
WarmFörm is especially suited for radiant heat slab applications in cold climate construction since the heating coils can be placed on the insulation before the rebar is placed. The slab and beams are formed in one pour, and there is no formwork to strip.
