Dynamic Joints Concrete Overhead
BlazeFrame Profiles:
- Unencumbered gaps require only 1/2” distance of overall deflection
- Maximize smaller 3/8” gap to accommodate up to larger 3/4” deflection
- Joint protection is provided behind base layer of wall sheathing
- No fatigue to the system for life of system
- Finished aesthetic look of rated joints match non-rated joints at concrete O/H
- Approaches addressing head of wall (rated and non-rated) joints throughout unit
- L-metal maximizing a smaller joint with exposed look (floating ceiling)
- Covering with crown molding
- Non-fire rated “finish” caulk applied to all exposed joints
- No affect on the protection of fire rated joints
- Can be replaced, removed, or repaired without affecting fire rated joint
BlazeFrame Ratings:
- Maximum Level III – 30 cycles/min (seismic) UL certification
- UL certified lowest leakage rating (less than 1 CFM/Lin Ft.)
- Up to 3″ joint protection with 100% Compression and Extension Capabilities
Caulk/Spray only Considerations:
- Fatigue experienced during life of system (loss of Life Safety rating/protection)
- Shrinking/Cracking during curing process
- Adhesive failure to concrete overhead or wall sheathing
- Cohesive failure of caulking material itself
- Dislodging due to compression of joint or direct contact
- Tenant remove/replace with non-rated caulk during life cycle
- Encumberance requires large gaps and limits joints to smaller movement capabilities
- Compression may have negative affect on assembly protection
- dislodge materials
- damage (crack) drywall reducing fire performance rating
- Extension may open gaps
- adhesive failure of caulk to overhead or wall sheathing
- cohesive failure of caulk material due to “three-sided” adhesion
Typical Caulk/Spray Ratings:
- Typical limitation is for level II -10 cycles/min movement (wind sway)
- Typical limitation is 25% movement ratings (i.e 3/4” movement requires 1” installed gap)
