LeakBarrier MS300 Ice and Water Armor is a glass fiber reinforced, self-adhesive modified bituminous roofing underlayment for use under slate and asphalt shingles. Mineral granules on the upper surface provide enhanced skid resistant properties.
Underlayment product selection is influenced by many factors. Primary roof covering, substrate type, roof design criteria, building codes, material cost, labor cost savings, life cycle expectations, walkability, exposure rating, warranties, climate and customer preference, to name a few, can all factor into the choice of underlayment.
To place these various factors into perspective, a good place to begin is a glance backwards at the history of traditional asphalt-saturated organic felt. That will help us to appreciate from a marketing perspective the entries of alternatives into the residential roofing industry. The new entries include premium self-adhering and synthetic underlayment products. The successful introduction of these new product categories into the residential roofing market is a remarkable story.Read more
The textile industry has been making fabrics from polymers for more than fifty years; as a result, the processes and equipment are highly evolved.
A fiber of continuous length is typically referred to as a “filament.” With modern equipment it is possible to convert a thousand pounds of polymers into filaments without a single break occurring. In the textile industry, molten polypropylene (PP) passes through an adapter into a die that has a pattern of holes in it. The liquid polymer being forced through these holes solidifies in a short distance, typically about 100 centimeters or 40 inches (one meter), and it can be further stretched or treated before winding onto spindles.Read more
