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.

Good Quality Control

Sandwich panel is the best choice for factories and warehouses in many industries. The panel is combined by two metal sheets with rock wool or eps/pu, pir foam in the middle. The production uses high-pressure combination process that makes panels strong enough for heavy industrial use. We have a strict testing of each panel before packing and loading.

Good Fire-Proof Performance

Rock wool sandwich panel has a very good fire proof performance for industrial buildings. With 50mm thickness rock wool core, it will have 60 minutes of fireproof time. While the thickness increases to 100mm, and you get 120 minutes of fireproof time. This kind of sandwich panel will give people enough time to escape while on a fire.

Good Noise Control

There is lots of loud machinery and equipment noise at some Industrial sites. As professional acoustic sandwich panel supplier, Propanel’s rock wool sandwich panels can keep down noise levels obviously. Rock wool noise-absorbing sandwich panel can effectively absorb noise and provide workers with a healthier working environment.

Energy-saving and Cost-saving

Although the initial cost may seem high, sandwich panel saves money in the long run. It’s insulation advantages reduce energy costs. The panel has anti-rust, anti-mold, and anti-pest performance with only common treatment. Most panels have 20 to 30 years life time and only needs basic cleaning work. Quick installation of less construction work also saves money for the project.
