What are the advantages of sandwich panels

Sandwich panels are an increasingly popular building material that offer a number of advantages. These panels are constructed from two pieces of metal, a top layer and a bottom layer, that are connected together with an insulating core of foam or other material. Using sandwich panels for construction makes the structure stronger, more energy efficient, and provides better acoustic and thermal insulation than traditional building materials like wood and concrete.

Insulation of sandwich panels

PU sandwich panels, PIR sandwich panels and rock wool sandwich panels have good thermal insulation properties., which could be proved by comparing with other construction materials in heat transfer coefficient. The panel has high insulation properties as much as 14-80 times than brick and concrete. The panel therefore is a best choice for the use of strict control of temperature requirements.Therefore, sandwich panels are used as cold storage panels in some cold storage with thermal insulation requirements.

Prevent condensation

There are two methods for building thermal insulation in general: internal thermal insulation and external thermal insulation. For internal insulation it would generate temperature difference in different divided spaces, such as indoor area and the back of small rooms, and resulting condensation normally. On the other hand, external insulation covers a building completely with insulation material; therefore the divided space between indoor area and the back of small rooms sharing stable temperature will not generate condensation. Sandwich panels adopt external insulation method which would prevent condensation effectively.Therefore, PU sandwich panels and PIR sandwich panels are often used as cold storage panels.

Fire Resistance of sandwich panels

The use of fire-resistant or fire-retardant materials for the core material in the middle of the sandwich panel can stop the fire from spreading in the event of a fire. The outer “skins” of the panel are designed to resist the spread of flames. These skins are often treated with special fire-resistant materials that create a barrier between the flame and the interior of the panel. This improves fire safety and reduces the rate at which fire can spread. Solideck’s rock wool sandwich panels have class A fire resistance, while PU sandwich panels and PIR sandwich panels have class B 2 fire resistance, which ensures the safety of the building under certain circumstances.

Durability of sandwich panels

Sandwich panels boast excellent strength and durability. The core is made from either Styrofoam or polyurethane foam. This foam insulation is both lightweight and incredibly strong, making it extremely capable of withstanding considerable force. It can also absorb shock, while retaining its structural integrity over extended periods of time.The prefabricated panels are made from either steel or aluminum, giving them an even greater strength. This makes sandwich panels an ideal choice for applications such as walls and roofs.

Sandwich panels have so many advantages that they are becoming more and more popular with our customers.
