eps core panels suppliers

Currently, common sandwich panel include EPS sandwich panel, PU/PIR sandwich panel and rock wool sandwich panel.   Generally speaking, the thicker the sandwich panel, the better the insulation effect. PU/PIR has the best thermal insulation performance, rock wool has the best fire resistance, and EPS has the highest cost performance，but no fireproof.   Due to the different properties of the core material, the application of sandwich panels with different core materials is also different, as detailed below.   Thickness EPS Sandwich Panel PU/PIR Sandwich Panel Rock wool Sandwich panel 50mm Suitable for interior wall partitions in ordinary workshops and factories where insulation requirements are not high, as well as prefabricated houses, temporary houses, temporary buildings on construction sites, and general storage. Suitable for roofs and walls of warehouses at normal temperatures, as well as steel structure exterior walls and roofs. Suitable for interior walls and partitions of ordinary factory buildings with high fire protection requirements and general insulation requirements, as well as walls of simple warehouses and temporary buildings. 75mm Suitable for industrial buildings with no strict temperature requirements, such as general warehouses, logistics warehouses, steel structure workshops, and livestock farms. Suitable for general cold storage and insulation, constant temperature workshops (such as electronics, packaging, light industry, etc.), food processing plants, beverage plants, pharmaceutical and electronics cleanrooms, etc. Suitable for general warehouses, logistics centers, office buildings, workshops, and showrooms. 100mm Suitable for walls and roofs of large factories and warehouses, stadiums, markets, and large steel structure buildings, etc. Suitable for industrial buildings, cold storage (0-5℃), food processing workshops, cold chain warehouses, etc., where high insulation and fire protection requirements are needed. Suitable for high-standard factories, cleanrooms, hospitals, schools, public buildings, etc. 150mm Suitable for buildings with high insulation requirements but limited budgets, such as ordinary factories and warehouses in cold regions. Suitable for high-end constant temperature and humidity workshops, pharmaceutical warehouses, low-temperature cold storage (-18℃), cold chain logistics centers, dairy, meat and seafood processing workshops, etc. Suitable for public buildings with strict fire protection requirements, large warehouses, long-span factories, and buildings with extremely high requirements for thermal insulation/sound insulation, such as concert halls.     In short, 50mm sandwich panels are suitable for interior walls, simple interior partitions, etc.; 75mm sandwich panels are suitable for ordinary factories and warehouses, etc.; 100mm sandwich panels are suitable for food factories and low-temperature cold storage, etc.; and 150mm sandwich panels are suitable for low-temperature cold storage and high-standard buildings, etc.

For a good cold room, to use the right way to finish the installation is very important, cause the cold storage room requires excellent sealing performance--Once the sealing performance cannot be guaranteed, It may greatly increase energy loss and spoilage of goods.    The cold storage sandwich panels—it is usually composed with 2-layer pre-painted steel sheet with polyurethane(pu)/polyisocyanurate(pir) insulated core material. As is known to all, the pu/pir is the best thermal insulation building material—so it gives the best cold storage performance with B1 fireproof at the same time.    First of all, ensuring that the quality of the cold storage composite panels is good is the top priority. Propanel, just focus on supplying the pu/pir cold room sandwich panels, give customers the best solution also best price at the same time.   Secondly, ground site preparation and inspection must be done before installation. If the foundation is uneven - the panels won't line up properly - this can cause gaps to appear, ultimately allowing cold air to escape.   Thirdly, node connections are easily handled improperly. Nodes such as column edge connections, wall corner connections, and suspended ceiling points require professional personnel to connect them according to professional instructions. Improper operation can cause cold bridge phenomenon, finally leading to energy loss and damage to the cold storage panels.
