QUICK OVERVIEW
 SlopeShield Plus SA is a self-adhering, water shedding, vapor-permeable roofing underlayment. It protects roof assembly materials by allowing vapor to pass through (breathable) while concurrently blocking liquid water and air - mitigating costly moisture damage and saving energy for the life of the building.A highly vapor permeable roofing underlayment Air Barrier (AB) material

LOW SLOPE ROOFS BELOW 2:12, LIGHTWEIGHT AND STRUCTURAL CONCRETE DECKS, NEW AND RE-ROOF
| 
 Typical Compact Roof: Apply SlopeShield SA Plus to top of thermal board. | 
 Lightweight Concrete Deck: Apply SlopeShield Plus SA directly to concrete roof deck. 
 | 
| 
 Structural Concrete Deck: SlopeShield Plus SA can be applied over green concrete or over a damp existing concrete roof deck provided the surface complies with a bull float finish or better. | 
 Re-Roofing: Installing SlopeShield Plus SA on new thermal board applied over existing insulation allows for the drying and reuse of existing insulation. |

Mass Timber Protection
|  | SlopeShield Plus SA
 | Taped Splines | 
| Install SlopeShield Plus SA over mass timber roof deck/floor deck to protect it from moisture intrusion and construction damage. | SlopeShield Plus SA protects mass timber from bulk water intrusion and concurrently dries mass timber through moisture vapor diffusion. | Alternative protection such as taped splines will leak and less durable lower perm sheet goods offer little to no drying capacity resulting in water damage and mold. |
