Solar Seal

To accompany our Clad Program systems we recommend NPC Sealant. We stoke 11 clad colors to make sure you have the perfect match, in the #900 Solar Seal.

The #900 Solar Seal is 100% “Terpolymer” Adhesive/Sealant and is formulated for long-term performance on vinyl, cedar, metals, masonry, stucco, skylights, fiberglass, roof flashing and termination bars. It is a high-performance alternative to urethane and silicone.


  • 300% elongation first year, 300% elongation twentieth year
  • Expectional joint movement capability
  • Full U.V. protection
  • Tenacious long-term adhesion
  • Paintable
  • Skins in one hour
  • Four-season application

TIP: After you cut a small tip on the tube keep the tip submersed in water to keep the sealant from drying out. This will keep the sealant fresh and ready to use.
