Product Details
The polyurethane sandwich wall panel produced (seamless version) by Henan Ruii Steel Construction Engineering Co.,Ltd. is a high-quality external wall enclosure material integrating thermal insulation, heat insulation, waterproofing and decoration. It is suitable for various external wall needs of buildings, with both practicality and aesthetics. The product supports two installation methods for external walls: vertical installation and horizontal installation, which can flexibly adapt to the design needs of different buildings such as industrial plants, office buildings and commercial complexes. It is convenient and efficient to install, greatly shortening the construction period.
The panel adopts a composite structure of “face panel + PU/PIR core + back panel”. The core has excellent thermal insulation and sound insulation performance, which can effectively reduce building energy consumption and meet the standards of energy-saving buildings. The face panel is weather-resistant, corrosion-resistant and uniform in color. After installation, the wall surface is flat and seamless, with a simple and elegant overall texture. Aiming at the problem of easy water leakage in vertical installation, the product adopts a scientific node design, accurately optimizes the sealing structure, fundamentally eliminates the hidden danger of rainwater leakage, ensures the stability and durability of the external wall for long-term use, and is the preferred product for high-quality external wall energy-saving enclosure.

Polyurethane Wall Sandwich Panel（seamed version)
The PU/PIR building external wall panel (seamed version) is a new type of external wall enclosure material integrating thermal insulation, heat insulation, waterproofing and decoration. It is mainly suitable for horizontal installation of external walls and is widely used in various buildings such as industrial plants, office buildings and commercial complexes. The panel joints can be flexibly adjusted, and combined with the four-sided tongue-and-groove process, it can present an exquisite aluminum curtain wall effect after construction, with both practicality and aesthetics.
