Features and Components
JM APP Base Plus is used as a base or ply sheet in APP multi-ply roofing systems.
APP (Atactic Polypropylene) Polymer and Asphalt Blend: Provides an extremely durable sheet with excellent weathering characteristics, flexibility and dimensional stability for ease of handling and quick installations.
Fiber Glass Reinforcement Mat: Offers excellent dimensional stability and tensile strength and withstands differential movement. Because it has no thermal memory less time is needed to relax the sheet, allowing for ease of installation. The fiber glass mat also has good lay-flat characteristics.
Surfacing: Fine mineral parting agent on both sides of the sheet. Enables the product to be applied using cold adhesive or heat welding techniques.
