Recently, the construction industry has witnessed a major breakthrough. The emergence of the new synthetic underlayment

technology has provided a more excellent solution for roof protection.

Traditional roof underlayment materials have gradually revealed many limitations during long-term use. For example, traditional

asphalt felt underlayment is easily affected by climate changes. It may crack and age under high-temperature exposure, which

greatly reduces its waterproof performance. In a low-temperature environment, it will become brittle and the risk of damage will

increase. Moreover, its service life is relatively short, usually requiring replacement within 5 to 10 years. Frequent replacements

not only consume manpower and material resources but may also cause potential damage to the roof structure during the

construction process.

The new synthetic underlayment, on the other hand, demonstrates significant advantages. It is mainly made of advanced

polymer materials, such as polyethylene, polypropylene or polyvinyl chloride, etc., and special components like anti-ultraviolet

additives are added. These polymer materials endow the underlayment with excellent flexibility and weather resistance, enabling

it to maintain stable performance under various harsh climate conditions. The anti-ultraviolet additives effectively slow down

the aging speed of the material caused by sunlight exposure and greatly extend its service life, which is expected to reach 10

to 20 years or even longer.

In terms of waterproof performance, the synthetic underlayment forms an efficient waterproof barrier by virtue of its dense

material structure and special coatings. Whether it is a torrential rain or the melting of ice and snow, it can effectively prevent

water from infiltrating into the interior of the roof and protect the integrity of the building structure. Meanwhile, its good tear

resistance, especially the addition of reinforcing materials such as glass fiber or polyester fiber in the reinforced synthetic

underlayment, has greatly improved the underlayment's ability to resist external forces during installation and use, reducing

the risk of damage caused by construction operations or extreme weather.

Currently, numerous construction enterprises have begun to actively adopt this new technology and apply it widely in residential

and commercial building projects. From pitched roofs to flat roofs, the synthetic underlayment can perfectly match various roofing

materials, providing all-round, long-lasting and reliable roof protection for buildings. It is expected to become the mainstream

choice for future roof protection projects and promote the construction industry to develop in a more efficient and durable direction.
