Cold Storage Construction Column Bearing Blocks-Products R-9300

General Plastics R-9300 Thermal Isolation Blocks series are a high-density cellular polyurethane material. They are designed to support heavy structural loads while insulating a building interior from the external elements. They are commonly used as column bearing blocks for cold storage facilities.


The R-9300 Thermal Isolation block is a high-density rigid cellular polyurethane material designed to support heavy structural loads while insulating a building interior from the supporting ground. Cellular polyurethane is a naturul insulator and even at the high densities needed for support of roof-column loads, R-9300 will provide thermal insualation value superior to lightweight concrete, treated wood blocks, and other materials typically used in this application.

Typical applications of this material include use as a thermal isolation load-bearing block in concrete footings for roof-column supports in refrigerated warehouse structures. The high-density of this cellular polyurethane material gives it strength to support large compressive loads with little deflection. Each lot of R-9300 material is tested and certified for its compressive-strength.

Product Features:

  • Blocks are custom-cut, with pre-drilled anchor bolt holes
  • Will not rot or dissolve in sub-grade applications
  • Does not release any chemical compounds into surrounding soil
  • Cellular polyurethane is a natural insulator
  • Delivered as a fully-cured, ready to use material, there is no waiting before moving on to the next construction step, saving precious time
  • Short-circuits energy transfer to cooler/warmer earth at foundation
  • High compressive strength to support roof-column loads
  • Closed-cell material will not absorb liquid water
  • Will not support insects or vermin
  • Compatible with grouts, adhesives, concrete; Will not promote steel corrosion
  • Standard blocks are single-piece, with no adhesive joints
  • Blocks are custom-cut, with anchor-bolt holes pre-drilled, if desired
  • Standard R-9300 blocks are available in 30 (R-9330), 35 (R-9335), and 40 (R-9340) pound-per-cubic-foot densities
  • R-9330 blocks are certified to support compressive loads up to 1,000 psi at 2% deflection. R-9335 and R-9340 blocks will support higher loads at similar 2% deflection
