Dow Rigid Insulation Under Slab

Use foamular 400 600 or 1000 for industrial applications where floor areas will be exposed to heavy loads.

Dow rigid insulation under slab.

Below grade under slab system with foamular extruded polystyrene rigid board insulation and radiant heating. When building a slab on grade eps rigid foam insulation is the most common choice of insulation for performance and cost. Additional insulation is applied along the edges of the slab because that is a primary surface for heat loss. Reduces energy loss between ground and concrete slab.

Spray foam for sure has uses where it is the best choice by a long shot but under a slab is not the place. Since its discovery in 1941 styrofoam brand xps insulation has a long and rich heritage as a sustainable building product insulating to meeting core thermal moisture air and vapor performance requirements through its rigid foam board technology.
