What is one advantage of using glass fiber mats in shingle manufacturing?

Using glass fiber mats in shingle manufacturing provides enhanced fire resistance, which is a significant advantage. The composition of glass fibers contributes to the overall fire-resistant properties of the shingles, making them less likely to ignite or sustain combustion when exposed to heat or flames. This characteristic is particularly important in roofing materials, as it helps protect structures from potential fire hazards, providing homeowners and builders with increased safety and peace of mind.

While the other options may present some advantages in different contexts, the specific benefit of fire resistance is a key reason for opting for glass fiber mats in shingles, making them a preferred choice in many roofing applications.
