Key Considerations for Choosing External Wall Insulation and Decoration Panels

How to choose exterior insulation and decoration boards has become a concern for many clients. With numerous manufacturers and a wide range of product quality, DAD editors introduce how to select high-quality exterior insulation and decoration boards.

One, thermal insulation performance of the exterior wall保温装饰一体板 integrated thermal insulation and decorative board

Certainly, the choice of exterior wall insulation and decorative panels focuses on their thermal insulation properties. The thermal performance is determined by the material used in the insulation layer. Generally, organic insulation materials (such as EPS, XPS, polyurethane, phenolic foam, etc.) offer better thermal insulation than inorganic materials (such as rock wool, glass wool, perlite, foamed cement, etc.).

Section 2: Fire Rating of External Insulation and Decoration Panel

While focusing on thermal insulation performance, the fire rating is also a critical factor we should pay close attention to. As an integral decorative building material, exterior wall insulation panels have a large installation area, and non-fire-resistant insulation materials are highly susceptible to fire spread. Therefore, we must choose exterior wall insulation panels with a high fire rating.

Similarly, the fire rating of the exterior保温装饰一体化板 is determined by the flammability of the insulation material. The fire rating of insulation materials is categorized as A and B levels. A-level insulation materials have superior fire resistance.

Grade A thermal insulation materials include: rock wool board, foam ceramic board, cement foam board, glass foam board, polyurethane composite board, composite material thermal insulation board, STP, perlite board, inorganic vitrified microbead thermal insulation mortar. Grade B thermal insulation materials: EPS external wall thermal insulation board, XPS external wall composite thermal insulation board, rigid foam polyurethane composite thermal insulation board, phenolic fire-resistant board, etc.

In terms of comprehensive thermal insulation and fire resistance, polyurethane exterior thermal insulation composite panels and phenolic exterior thermal insulation composite panels currently offer the best performance in both categories and are the most widely used.

Section 3: Service Life of External Wall Insulation and Decoration Panels

The service life of exterior thermal insulation and decorative panels is typically between 20-30 years.

Four, Construction Services

In addition to focusing on the quality of the exterior wall insulation and decorative integrated board product itself, another factor that deserves equal attention is the technical expertise of the manufacturer in serving the construction party.
