Polyisobutylene Primary Seal Tape
Double Glazing Components

Polyisobutylene Tape

Polyisobutylene (PIB) tape is a double-sided, butyl rubber, self-adhesive tape reinforced with cotton mesh for stability. The unique tape has been developed for rigid spacer bar application in insulated glass units and should be used in conjunction with a secondary sealant of either hot melt butyl, silicone, polyurethane or polysulphide.

Packaging: Supplied on rolls of 0.6mm x 3mm x 30lm and boxes of 100 units

Polyisobutylene tape functions as a primary seal in dual-seal systems, providing the main barrier for moisture vapour transmission and gas loss between the glass and spacer. The tape can be applied by hand or with the GMS PIB Tape Applicator.
