WebRigid foams are polyurethane materials mainly used for sealing and insulation. They can be divided into block, one-component, spray and pourable foams. They show similar properties, but they differ in the method of application. Block foams are made by cutting a block of rigid foam into slabs with specific thickness values. WebAn insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density. The R-value of most insulations also depends on temperature, aging ...
WebRigid Polyurethane Foam. Rigid polyurethane foam is a low-density PU system often used in fire retardant parts and insulation panels.
