Standard Backer Rod insulation is customarily used in a joint to control sealant depth, insulate the underside of sealant, and to allow proper sealant tooling and wetting of joint surfaces.
Backer Rod, a non-absorbent, compressible material, is commonly used in the following projects:
• Glazing Operations
• Window and Door Applications
• Expansion Joints
• Log Construction
• Pavement Joints
Backer Rod is chemically inert and will resist gasoline, oil and most other solvents.
