The environmental protection policy promotes the growth of the roof underlay market size mainly in the following aspects:

Demand side

Mandatory requirements of green building standards: Environmental protection policies in many countries and regions

stipulate that new buildings must meet certain green building standards to obtain approval or relevant preferential policies.

Green buildings have strict requirements for the environmental protection and energy - saving performance of roof underlays.

For example, roof underlays are required to have good heat insulation and thermal insulation properties to reduce the energy

consumption of buildings. This has increased the demand for high - performance and environmentally friendly roof underlays

that meet green building standards.

Enhanced consumer environmental awareness: Under the publicity and guidance of environmental protection policies,

consumers' environmental awareness has been continuously improved, and their requirements for the environmental friendliness

of the living and working environment are also increasing. When choosing building products, consumers are more inclined to

choose environmentally friendly roof underlays. This prompts builders and developers to increase the use of environmentally

friendly roof underlays to meet consumer needs, thus driving the growth of the market size.

Supply side

Elimination of backward production capacity: Environmental protection policies have strictly regulated the environmental

protection standards of roof underlay manufacturers, eliminating enterprises with backward production processes, serious

pollution, and substandard product quality. This has concentrated market resources on enterprises with more environmental

advantages and technical strength. These superior enterprises can more stably supply high - quality environmentally friendly

roof underlay products, ensuring the effective supply of the market and providing a basis for the growth of the market size.

Incentives for enterprise innovation: In order to meet the requirements of environmental protection policies, enterprises

have increased their investment in environmental protection technology research and development and product innovation,

developing more environmentally friendly and higher - performance roof underlay materials and production processes, such

as the use of recyclable materials and water - based coatings. This has improved the competitiveness of products, expanded

the scope of market application, and thus promoted the expansion of the market size.

Market standardization and expansion

Promotion of international market access: With the increasing global awareness of environmental protection, the demand

for environmentally friendly products in the international market is also increasing. The environmental protection policies of

various countries have gradually converged the international standards for roof underlay products. Environmentally friendly

roof underlays produced by enterprises are more likely to meet the market access requirements of different countries and

regions, which is conducive to expanding the international market, increasing export volume, and thus driving the growth of

the global roof underlay market size.

Release of demand in emerging markets: Driven by environmental protection policies, some emerging markets have begun

to pay attention to the environmental protection and sustainable development of buildings, and the demand for environmentally

friendly roof underlays is gradually increasing. For example, in the process of infrastructure construction and urbanization in

some developing countries, roof underlay products with higher environmental protection standards are beginning to be adopted,

bringing new growth space to the roof underlay market.
