Butyl Tape
Butyl tape is 100% solid, nonhardening, nonskinning & permanently tacky pre-formed sealant formulated to the appropriate standards for nonstructural metal to metal sealing and for sealing and bedding glass into wood, vinyl and aluminum sash. The sealant is furnished on release paper rolls. The sealant is based on polyisobutylene and a cross-linked butyl blend, formulated specifically for easy installation on substrates at temperatures as low as -20° C (-4°F). It is designed to create a long lasting, flexible weather seal between the two similar or dissimilar surfaces which will be subjected to normal expansion/contraction and wind loading force. Formulated to pass AAMA spec., 807.1-85 for glazing tapes to be used with architectural aluminum.

Butyl Caulking
Butyl caulking is a flexible compound formulated to seal against weather, moisture and dust. It also acts as a noise dampener between metal panels. It is nonstaining sealant which offers excellent adhesion to metal, glass, concrete and wood surfaces. This superior Butyl Caulking offers better adhesion and flexibility than conventional oil based or acrylic latex caulks over a wide temperature range.
