Technical Details & Test Data
- Limitations
The installed system acts as a vapor barrier. Concrete should not be fully encapsulated in areas of freeze/thaw.
- Competitive Testing and Additional Physical Testing
Competitive Testing - V2 Structural Systems takes its performance values very seriously and commits to its unique performance in each properly installed application. The following chart compares commercially available data with performance values (both typical and design) for StructureWrap V2 280 UG versus commonly available glass reinforcement systems. Note that the StructureWrap V2 280 UG Design and Typical values exceed the standard values of all competitive products in the industry.
Safety & Health
- Caution
StructureWrap V2 280 UG is non-reactive and non-toxic. However, caution must be used when handling since stray fibers and dust may be present on the surface. Gloves and the use of an appropriate properly fitted NIOSH approved respirator is recommended to prevent skin and lung irritation when handling, cutting and applying StructureWrap V2 280 UG.
