In the current era when people are striving for green living and sustainable development, the choice of building materials has

become a crucial aspect in the topics of environmental protection and health. Recently, synthetic roof underlayment has stood

out with its remarkable environmental and health advantages, forming a sharp contrast with traditional asphalt felt.

Research shows that synthetic roof underlayment does not contain a large amount of asphalt. This characteristic leads to a

significant reduction in the release of volatile organic compounds (VOCs), thereby greatly reducing the generation of odors.

This not only means the disappearance of pungent odors during the installation process, but more importantly, it creates a

healthier indoor and outdoor environment for installers and residents, effectively reducing the potential harm of harmful gases

to the human respiratory and nervous systems. It is worth mentioning that some synthetic roof underlayment products are

recyclable, which perfectly aligns with the current development concept of green buildings and provides strong support for the

sustainable development of the construction industry.

On the contrary, the asphalt component in traditional asphalt felt will gradually release unpleasant odors and VOCs with potential

health risks during the usage process. Long-term exposure to such an environment may cause chronic damage to human health.

From the perspective of the entire life cycle from production to disposal, the environmental footprint of asphalt felt is rather heavy.

Its production process consumes a large amount of energy and emits greenhouse gases. And at the end of its service life, due to its

material properties, it is difficult to recycle it efficiently and it often becomes construction waste that is hard to handle, bringing potential

pollution risks to soil and water sources and exacerbating the environmental burden.

By comparison, the advantages of synthetic underlayment in terms of environmental protection and health are obvious. While

reducing the health risks to installers and residents, it also contributes to the ecological environment of the earth. With the

continuous improvement of the public's awareness of environmental protection and health, as well as the construction industry's

continuous pursuit of sustainable development, synthetic roof underlayment is expected to gradually replace traditional asphalt

felt and become the mainstream choice for roof underlayment in future buildings, opening a new chapter of environmental protection

and health in the field of building materials and leading us towards a greener and more livable living and working space.
