In the continuous development of the construction industry and with the increasingly refined requirements for quality, various lining

products have become indispensable key materials in construction projects by virtue of their strict adherence to standards and

excellent performance, safeguarding the stability and safety of buildings.

The reason why these lining products can gain a firm foothold in the field of building protection largely lies in their strict compliance with

a series of standards formulated by the American Society for Testing and Materials (ASTM). Take ASTM D226 standard as an example. It

focuses on regulating various indicators of asphalt-saturated organic felts used for roofing and waterproofing, covering multiple aspects

from the basic physical properties of materials to precise dimensional tolerances. Lining products manufactured in strict accordance with

this standard are like a solid line of defense, which can effectively resist water penetration under normal circumstances, laying a solid

foundation for the waterproofing project of buildings and ensuring that the interior of buildings is free from moisture problems.

The ASTM D4869 standard cannot be ignored either. It centers on non-asphalt-based sheets used for roofing and waterproofing and sets

strict measurement standards for key properties such as tensile strength, tear resistance, and weather resistance of materials. Lining

products that meet this standard have obvious advantages in practical applications. During the installation process, they possess good

toughness and strength and are not easily damaged by external forces such as construction operations, thus ensuring the smooth progress

of construction. And during the long-term use process, regardless of the complex and changeable climate conditions, whether it is exposure

to the scorching sun or being battered by wind, frost, rain, and snow, they can always maintain stable performance, greatly extending the

service life of buildings and reducing maintenance costs and potential safety hazards caused by the aging or damage of lining products.

In terms of meeting the special requirement of ice-water barriers, the ASTM D1970 standard plays a vital role. This standard specifies key

indicators such as bonding performance and impermeability under low-temperature conditions for self-adhesive polymer-modified asphalt

waterproofing rolls and other products used on steep-slope roofs. Lining products that meet this standard are like "guardians" on the roofs

of buildings in cold environments. Even under harsh conditions where ice-water is prone to accumulate, they can rely on their excellent

anti-ice-water penetration ability to firmly protect the roof structure, preventing roof deformation, indoor water leakage and other

problems caused by ice-water leakage, and ensuring the normal use and living comfort of the interior of buildings.

In addition to strictly following ASTM standards, lining products also have outstanding performance in terms of compatibility with

building codes. Roof lining products with ICC-ES reports are undoubtedly powerful evidence of building compliance. The ICC-ES

reports clearly demonstrate their perfect fit with the International Building Code (IBC) and the International Residential Code (IRC).

e International Building Code (IBC), as an important universal code system in the global construction industry, has detailed and strict

requirements for many aspects such as the structural integrity of buildings, fire safety, and overall functionality. The fact that roof lining

products comply with the IBC means that they can seamlessly cooperate with other building components to jointly build a safe, reliable,

and fully functional building as a whole, ensuring that each link of the building, from planning and design to actual construction and then

to use, can meet high-quality standards.

The International Residential Code (IRC) focuses on providing comprehensive guidance for residential construction, with clear regulations

on various dimensions such as ensuring the comfort and safety of residents and improving the durability of residences. When roof lining

products meet the requirements of the IRC, they can give full play to their advantages in residential projects, creating a dry, warm, and safe

living environment for residents, so that people don't have to worry about roof leakage and other problems when facing changes in various

natural conditions and can enjoy a comfortable home life at ease.

In numerous construction practice cases, lining products have won wide acclaim from architects, contractors, and property owners by

strictly adhering to ASTM D226, D4869, and D1970 standards and possessing ICC-ES reports that conform to building codes. Whether

it is commercial building projects such as high-rise buildings or cozy residential construction projects, lining products are quietly playing

an important role, effectively ensuring the effective realization of key functions such as waterproofing and protection in buildings,

contributing indispensable strength to the creation of high-quality, durable, and reassuring building spaces, and also indicating that

they will continue to shine in the future construction field and help the construction industry continuously move towards higher quality

levels.
