When you’re in the market for filled cavity insulation assemblies, there are two main systems you need to know: Long Tab Banded and Simple Saver Liner.
But in order to know which is right for you, you’ve got to weigh the pros and cons of each. Once you understand their differences, you can decide the best-fit system for your metal building.
Long Tab Banded System
This is often explained as a filled cavity system. It uses laminated insulation that’s parallel to the purlins with long facing tabs that have to be held to the tops of the purlins, which suspends the insulation into the cavity between the purlins, leaving the purlins exposed.
Pros
- Cost-effective
- High R-Value
- Meets specified U-Values defined in current energy codes and standards
- Easier access to purlins for HVAC, electrical and maintenance services, reducing the number of penetrations in vapor barrier.
- Provides mechanical support from underneath
- Much more efficient that the old ‘Sag and Bag’ technique
- Long-lasting
- Class A fire safety rating
- Installation is not as technical as a Simple Saver Liner System
Cons
- Does not provide fall protection.
Simple Saver Liner System
This is typically a little more expensive than the Long Tab Banded System. It is a fabric liner system that provides Osha approved fall protection and isolates the purlins from the inside air.
Pros
- Strong and durable for longevity
- Osha approved fall protection
- Bright white fabric liner and concealed purlins increase light reflectivity, saving money on lighting equipment
- Helps prevent condensation
- Minimizes insulation compression, while still assuring fundamental performance
- Provides low U-Values for energy code compliance
- Class A fire safety rating
Cons
- Harder access to purlins for HVAC, electrical and maintenance services
- Installation is fairly complex. Qualified installers are recommended.
- Not as budget friendly as a Long Tab Banded System.
