DENVER FOAM® OPEN CELL BACKER ROD – POLYURETHANE SEALANT BACKING
Improve joint performance and reduce sealant waste with Denver Foam® Open Cell Backer Rod. Designed to control sealant depth and create the ideal hourglass configuration, this backer rod ensures proper adhesion, flexibility, and long-term durability across a wide range of applications.
KEY FEATURES
- Controls sealant depth: reduces excess sealant use and ensures proper joint design
- Open cell structure: allows air flow for complete two-sided sealant cure
- Enhances joint performance: promotes proper adhesion and cohesion
- No out-gassing: eliminates bubbling issues common with closed cell backer rods
- High flexibility: stretches up to 90% to accommodate joint movement
- Wide temperature range: performs from -60°F to +500°F
APPLICATIONS
- Expansion and construction joints
- Concrete and precast walls
- Curtain walls and glazing systems
- Bridge and highway construction
- Parking decks and pavements
- Log home construction
- Saw-cut control joints
