Modi Systems - Modi 4.5 Slate

- MODI 4.5 SLATE:
Modi 4.5 Slate is a plasticized bituminous roofing membrane consisting of a compound of distilled asphalt mixed with atactic polypropylene and various petrochemicals. When the asphalt is modified in this way, it imparts flexibility to the compound. The compound is bonded around a polyester core. The distinctive characteristics of the polyester core material include high tensil strength coupled with elongation capability, strength, toughness and excellent dimensional stability.

MODI 4.5 SLATE FEATURES:

Modi 4.5 Slate is designed for use in most roofing and waterproofing situations, including new construction and reroofing.

Modi 4.5 SLATE is an APP torch-applied modified bitumen roofing membrane reinforced with a nonwoven polyester mat. Its finished surface is composed of authentic French slates available in two colors: white and gray.

INSTALLATION: Modi 4.5 Slate is easy to install using a proper Modi-Torch and Modi-Trowel.

WARRANTY: Modi 4.5 Slate carries our warranty from 10-20 years, depending upon the specification used.

Modi 4.5 Slates roofing products are intended for use by professional roofers only and are not intended for use by amateurs. Use of the torch and/or hot asphalt application methods represent potential fire/burn hazards and all appropriate safety measures and cautions should be taken. It is the sole responsibility of the applicator to exercise all necessary safety procedures.
