LAST-A-FOAM® R-9300 Continuous Insulation Series 

The LAST-A-FOAM® R-9300 Continuous Insulation Series for cold-storage and industrial buildings couples a thermal barrier with high-strength structural support. These high-density polyurethane foam construction blocks extend building insulation from below ground to the building’s roof. A wide range of compressive strengths is offered to address industrial thermal construction applications: 350, 500, 1,000, 1,500 and 1,800 psi.

Structural Thermal Isolation Column Block

LAST-A-FOAM® R-9300 Thermal Column-Bearing Blocks are designed to support heavy and structural loads while maintaining thermal control within industrial building interiors. Made of proven, high-density rigid cellular polyurethane material, these blocks are ideal for cold-storage facilities. They combine high compressive strength with little deflection and extraordinary thermal insulation.  

Tank Vessel Isolation Protection Block

These concave insulating blocks securely support chiller equipment outside cold-storage facilities. They prevent thermal energy transfer through the concrete between the tank and earth below.

Canopy/Mansard Support Block

Our high-density polyurethane foam blocks provide a thermal barrier for metal canopy or mansard supports where they are anchored to building exterior walls.

LAST-A-FOAM® R-9320 Thermal Floor Reinforcement Blocks

These thermal blocksprovide economical load-bearing shelving support inside cold-storage facilities while preventing thermal energy loss between the floor and ground. This stable polyurethane stock material eliminates the need for other thermal protection, such as gypsum foam. General Plastics provides blocks to your specified dimensions.

Equipment Support Block

Placed on top of the building’s roof, these insulating blocks support HVAC and other heavy equipment while preventing radiant heat transfer to the building’s interior. This added insulation keeps the building interior cooler and reduces the load on cooling equipment, lowering utility costs.

Perimeter Fall Protection Block

These sturdy blocks are a key component of a commercial or industrial roof safety system. Our R-9300 Series polyurethane blocks are custom-cut with pre-drilled anchor-bolt holes for securing to the surface of existing roof structures. The high-density material provides greater load-bearing ability and durability than wood while preventing cold air from escaping through concrete supports for perimeter posts.

Precast /Tilt-up Concrete Wall Panel Blocks

Our R-9300 Series prevents thermal energy transfer between the building and ground when installed under precast and tilt-up concrete walls. Because these insulating construction blocks offer excellent load-bearing ability and durability, only a few are required to support each wall. This eliminates wasted material while preventing costly energy loss.
