Flexible Elastomeric Foam
Foam sheets and tubing insulation containing vulcanized rubber.
Insulation Types, Forms & Finishes:
Insulation Finishes: Insulation finishes are important because the ability of an insulation system to perform as designed and specified is dependent upon protection from moisture, weather, chemical and mechanical damage. Insulation can also be used to enhance system appearance. Weather Barriers: Protect the insulation from rain, snow, ice, sunlight, ultraviolet degradation, ozone and residues of chemical compounds in the atmosphere.
Mastic
Metal
Plastic
Roofing felt
Vapor Retarders: Retard the passage of moisture vapor from the atmosphere to the interior of the insulation system.
CPVC
FRP
Laminated foil-scrim membranes
Mastic
Metal
Plastic
PVC
Reinforced polyester resin
Mechanical Abuse Protection: Rigid jacketing provides protection against mechanical abuse from personnel equipment, machinery, etc.
Metal
Plastic
Appearance: Chosen primarily for appearance value in exposed areas.
