Thresholds and Seals
High-Performance Thresholds
Composite Thresholds incorporate the patented ImperiSeal™ technology, a continuous filament that positively seals the adjusting rail to the deck of the sill, thus eliminating any chance of water intrusion through the threshold. The cellular PVC rail is extremely resilient to long-term exposure to temperature changes, wind, and snow.
Features
- Meets code and design requirements
- Precision-engineered rails adjust upward (3/16”) and downward (1/16”) using flush screws, while the rail interlocks with a high-dam aluminum sill
