Cast a Vote for Precast

Layers in cakes are good. Layers in precast concrete walls are just plain smart.

Used in insulated precast, prestressed or tilt-up construction, rigid foam insulation products from Dow combine insulating capabilities with the added strength of concrete. The foam is sandwiched between two wythes of concrete and held together structurally by metal or nonconductive connectors.

When rigid foam insulation from Dow is part of the recipe, it’s wise to cast a vote for precast.
