dry seal:A weather seal between a window's glass and sash by use of strips or gaskets of neoprene, EPDM, silicone or other flexible material. A dry seal may not be completely watertight.
Glass-Seal?:A three-tab, self-sealing TAMKO? fiberglass shingle roofing product with a traditional square-tab design. A thick layer of weathering-grade asphalt gives it extra waterproofing protection. These shingles are UL Class A fire-rated and backed by a 20-year limited warranty. Algae-resistant granules are optional.
hermetic seal:A vacuum seal between the panes of a double-paned window or insulated glass unit (IGU). A hermetic seal that fails causes permanent fogging between the panels of the IGU.
polysulfide sealant:A type of polymer sealant which is mercaptan-terminated, having long-chain aliphatic polymers containing disulfide linkages. It can be converted to rubbers at room temperature without shrinkage upon the addition of a curing agent.
polyurethane sealant:An organic compound formed by the reaction of a glycol with an isocyanate and used as an adhesive and for sealing and waterproofing decks, wood flooring, trim, etc.
pre-shimmed tape sealant:A sealant having a pre-formed shape containing solids or discrete particles that limit its deformation under compression.
sealant:An elastomeric material with adhesive qualities that is applied between components of a similar or dissimilar nature to provide an effective barrier against the passage of snow, rainwater, wind, etc.
sealer:A clear or pigmented finishing material that is usually applied directly over uncoated wood for the purpose of sealing the surface.
silicone sealant:A multi-purpose sealant that typically does not shrink or crack and offers flexibility and adhesion, and a weatherproof, watertight seal.
sill seal:Fiberglass or foam insulation installed between the foundation wall and sill (wood) plate, designed to seal any cracks and gaps.
sill sealer:A foam strip placed between the top of the foundation wall and the sill plate to facilitate a better fit and eliminate water problems.
two-part sealant:A product composed of a base and curing agent or accelerator, necessarily packaged in two separate containers that are uniformly mixed just prior to use.
wet seal:An elastomeric sealant between window glass and its sash to form a weathertight seal.
