Fontana Paper Mills adds a new product to the family |

Wanting to offer the roofing community more underlayment options, Fontana came up with their newest product, the M40

FONTANA, Calif., May 23, 2022 (SEND2PRESS NEWSWIRE) — Fontana Paper Mills is proud to announce a new 6%+ SBS Modified Multipurpose Underlayment, otherwise known as M40. It has an organic core with a 6% + SBS modified asphalt surfacing and Fontana’s familiar high-grip surface.

The M40 is similar to our G40 but has the advantage of availability, price, increased flexibility while maintaining weather resistance and the extended life of a modified asphalt. M40 is covered by the Fontana Premium Leak Warranty when applied in accordance with the enhanced provisions of the TRI Moderate Climate Specification by a TRI certified roofer.

“The M40 is a special product because Fontana is able to control the quality of asphalt viscosity and melting point. By controlling all aspects of M40’s manufacturing process, M40 is more flexible. A more flexible product makes the work of roofers easier. Roofers have found that they have less product breakage when installing the M40 and it bends very well when cold,” said George Thagard, president of Fontana Paper Mills.

“M40 also has increased longevity because it’s not as UV-sensitive as other underlays; thus, it does not break down as quickly. The M40 also has superior nail sealing capability which will reduce the risk of roof leakage due to installation.

The M40 is also a more affordable product. Fontana, as a manufacturer, is able to keep costs low while maintaining its high quality underlayment standards, making the product more affordable for the roofer.
