Blue Shield Asphalt Barrier Papers from Holland Manufacturing provide a semi-permeable moisture resistant barrier. Unlike a poly-coating, asphalt barriers have higher moisture vapor transmission rate (MVTR) values, allowing for gradual transmission of moisture.
This makes Blue Shield Asphalt Barrier Papers the ideal choice for:
- Underlayment for wood and tile flooring
- Slip layer between sub-floor and finished flooring for noise control
- Countertop underlayment
- Concrete curing
- Export packaging
