Hybase MF-95-SS

High performance modified bitumen, fully adhered base sheet using a tough, non-woven, reinforced polyester mat strengthened with select glass fiber strands, coated on both sides with select SBS polymers and premium asphalt.

  1. HyBase MF‑95‑SS Base sheet possesses a fine mineral surfacing to provide enhanced adhesion with either cold applied adhesives or mopping asphalt.
  2. HyBase MF‑95‑SS Base is an excellent choice as the “lay flat” base sheet in a layered membrane construction system.
  3. Both sides are sanded to allow installation via mopping asphalt or a Hyload approved cold process adhesive.
