Building materials, especially insulated wall panels, face particular difficulties when it comes to humid climates. Such wall panels must maintain thermal insulation and structural integrity while being moisture resistant. In humid environments, core material selection is critical for achieving insulation wall panels durability and performance.Hebei Zhongtian Weiye Technology Co., Ltd., with 15 years of experience in manufacturing high-quality insulated wall panels, has summed up the most suitable core materials for humid areas through extensive research and project practice. Today, we’ll explore these core materials and their advantages, helping you make informed choices for your projects.

Rock Wool Core Material for Insulated Wall Panels

Rock wool is an ideal core material for insulated wall panels in humid areas, thanks to its excellent moisture resistance.The rock wool core insulated wall panels manufactured by our company utilize high-density rock wool which has improved fireproof certifications and a porous structure which does not easily absorb moisture. When compared to materials that swell or deteriorate from moisture, rock wool retains its structure and performance in high moisture environments.The rock wool core is treated with hydrophobic agents, further enhancing its moisture resistance and preventing mold growth. Our insulated wall panels with rock wool cores have passed strict humidity resistance tests, capable of withstanding long-term exposure to humid air and occasional water splashes. Additionally, rock wool has inherent fire resistance and sound insulation properties, making insulated wall panels not only moisture-proof but also safe and comfortable. This core material is widely used in coastal areas, rainy regions, and industrial workshops with high humidity.

PIR Core Material for Insulated Wall Panels

In humid regions, another great core material for insulated wall panels is PIR (polyisocyanurate). Our company’s insulated wall panels with PIR cores have dense, closed-cell structures that moisture penetration.The closed-cell rate of PIR core material is over 95%, leaving almost no space for moisture to enter. PIR is moisture resistant and maintains its dimensional stability, unlike PU (polyurethane) which can absorb moisture over time. This guarantees that no deformation or loss of thermal insulation will occur to insulated wall panels, even in a humid environment. Our insulated wall panels with a PIR core are CE-ROHS certified. This means that they are free of harmful substances and are safe for the environment. Furthermore, they are highly durable and have excellent compressive strength. They can therefore be used for internal and external walls in humid environments. PIR core insulated wall panels are equally effective in cold storage facilities in tropical climates and in commercial buildings located near rivers.

Glass Wool Core Material for Insulated Wall Panels

Glass wool is a cost-effective core material option for insulated wall panels in moderately humid areas.The glass wool core insulated wall panels of our company use premium quality glass wool that has undergone a hydrophobic treatment as a result of which, the glass wool core provides excellent thermal insulation and sound absorption, and the moisture absorption is reduced. Additionally, the glass wool core is covered with a moisture-resistant film that blocks contact with humid air, and increases moisture resistance.Unlike inferior glass wool that easily gets damp and deteriorates, our glass wool core insulated wall panels undergo strict quality control, ensuring uniform fiber distribution and stable performance. They are lightweight and easy to install, reducing construction costs and time.This core material is ideal for use in residential structures, office buildings, and light commercial end uses in environments with a moderate degree of humidity, and is engineered to provide a satisfactory balance between performance and economics.

Key Factors to Consider When Choosing Core Materials for Insulated Wall Panels

When selecting core materials for insulated wall panels in humid areas, several factors must be considered.Materials should be selected for their moisture-resisting qualities, such as water-repellent, low water absorption, and other hydrophobic traits. Insulation persistence in thermal insulation fosters savings energy insulating wall panels. Biological load and material deterioration resistance are aided through mold and corrosion resistance. Lastly, moisture traps are gaps left by insufficient bonding of the core material with metal surfaces.Our insulated wall panels are designed to incorporate these considerations with core materials that are internationally certified and tested. We also offer consultancy based on humidity and site conditions so you can make the best choice on core material.
