Types of OSI Construction Products

Sealants & Construction Adhesives

OSI sealants provide flexible sealing options for compatible joints, gaps, seams, and transitions where air or moisture intrusion must be managed. Construction adhesives provide bonding solutions for compatible wood, metal, masonry, concrete, and other building materials. Performance requirements vary according to the substrates and application.

Spray Foams

OSI spray foams provide options for filling and insulating compatible gaps, voids, and penetrations within building assemblies. Available formulations and suitable applications vary according to the location, opening, adjoining materials, and required sealing or insulating function.

Flashing & Specialty Tapes

Flashing and specialty tapes support compatible window, door, opening, and wall assemblies where air and moisture management are required. Tape selection should account for the substrate, surrounding building materials, and intended integration with the assembly.

Choosing OSI Construction Products

Choose OSI products according to whether the application requires sealing, bonding, insulating, or flashing, along with the substrates, interior or exterior exposure, anticipated joint movement, and building assembly. Verify product compatibility and application requirements before selection.
