Polyethylene Backer Rod is an ideal and professional solution for filling expansion joints and structural gaps before applying insulating materials (silicone or mastic). It is made from flexible cylindrical polyethylene foam to ensure the necessary support for the sealant and control its depth, guaranteeing a tight and long-lasting seal.
Key Features:
-
Professional Filling: Perfect for filling expansion joints and cracks to ensure the correct amount of sealing material is used.
-
High Flexibility: Flexible cylindrical design makes it easy to insert and shape into gaps of various sizes.
-
Versatile: Used as a primary filler before silicone, and can also be used to seal holes resulting from the installation of TopDek panels.
-
Chemical Resistance: Polyethylene material is chemically inert and does not react with most types of sealants.
-
Cost Savings: Reduces the amount of sealant consumed by filling deep voids.
