Butyl Preformed Sealant Tape
Tremco 440 Tape is a 100% solid Polyisobutylene cross-linked butyl, preformed sealant.
It is used for non-compression glazing of vision lites and spandrel panels in PVC metal and wood frames, in low rise building construction. It is unaffected by UV through glass and remains flexible at low temperatures. A 6" (150 mm) toe bead of compatible sealant at each corner is required to minimize potential for water infiltration.

IMPORTANT INFORMATION
Limitations
Not for use in joints subjected to continuous water immersion or temperatures exceeding 158 °F (70 °C). A compatibility test is required when used in conjunction with sealants other than approved Tremco silicone sealants.
Not for use with lites of glass over 75 UI (1905 mm). As the size of the lites approaches 75 UI (1905 mm), 50" (1270 mm) in height or 8 to 10 ft² (.743 to .929 M²) in area, a higher performance glazing system should be considered, such as the use of POLYshim® II Tape. Contact your local Tremco Sales Representative for guidance.
