CRL butyl architectural glazing tape is an extruded, preformed tape applied on easy release paper rolls. With its butyl-based rubber foundation, this butyl tape has proven to be weather resistant and is specially designed to be long lasting by providing a flexible yet durable weather seal between two surfaces when subjected to normal expansion/contraction and wind loading forces. It is used as an exterior primary spacing and glazing seal when glazing glass into a window sash. This sealant tape can also be used to seal other architectural surfaces such as metal to metal joints, wood to glass, metal to plastic, etc. The thickness of this glazing tape is designed to be compressed approximately 10 percent at installation to accommodate surface alignments.
