Product Details

Envirosheet - Under-Concrete - R10 - (with bottom drainage grooves) 8 sheets kit (each sheet 2 3/8 in. x 2ft. x 4 ft.) - total coverage 64 sq.ft., is a special High-Density EPS foam product designed for applications which require fresh concrete to come directly in contact with the insulation, where low water absorption and high strength are the key. Ideal applications include basement walls, frost protection for foundations and footings, under any type of on-grade or below-grade slabs, pads, or sidewalks. All sheets are 24 in. x 48 in. x 2 3/8 in. thick, which allow fast easy installation in even tight locations like basements and crawl spaces, and they can be transported in any regular car due to the convenient package size.
  • Board compressive strength is 22 psi or 3000 lbs. per sq. ft. load capacity, the panel has an R10 value and has less than 1.5% water absorption
  • Envirosheet UC Type II is acceptable for above and below grade applications - roof, floor and wall insulation in residential, agricultural, commercial and industrial construction
  • When used under concrete the raised square blocks and deep valleys on the one face act as additional anti-fracture reinforcing and should face the concrete side. Under wooden sub-floors, the grooves allow for air and water movement.
  • Can be used for the following applications: exterior/interior above-grade walls exterior/interior below-grade walls attic insulation re-siding projects slab on grades exterior roof decks cathedral ceilings cavity walls radiant floor heating snow melts as well as free-floating subfloor underlay insulation.
  • Exceptional Long-Term Thermal Resistance (LTTR) and increased R-Value in lower temperatures. High vapor permeance allowing wall assemblies to dry over time. No off-gassing and does not contain HFCs, CFCs or HCFCs.

Q:My covered front porch leaks water into the cold storage room underneath during really bad thunderstorms. Can I apply this under the boards--i.e., to the ceiling of the cold storage room? Thinking grooves will allow evaporation.

Answer This Question

A:  I used these styrofoam panels to insulate and provide a nice finishing touch to a small cold storage area in my basement. They are more robust than regular styrofoam so they do not flex much and do a great job as insulating panels. With regards to your question, it is my thought that any leaking roof system needs be addressed to find and fix the source of the leak vice applying a product such as these panels to help catch leaking rain water in the hopes that evaporation will solve your problem. Installing these panels underneath "the boards" as stated in your question might only serve to retain the leaking rain water up against the boards such that the boards will stay damp and rot out over time.
