Designed to maintain low temperatures in cold storage and controlled environments, Cold Storage Sandwich Panels feature insulating cores with low thermal conductivity (between 0.022 to 0.028 W/m·K), enhancing energy efficiency. The special connections of these panels ensure complete insulation.
Suitable for environments with high sanitary requirements, such as pharmaceutical and electronics industries, Cleanroom Sandwich Panels have smooth surfaces and are easy to clean, providing the necessary sanitary conditions, such as smooth and seamless surfaces to prevent contamination, chemical and detergent resistance, non-particle generation, and repeated easy washing.
Sandwich Panels with rock wool cores (10 to 24 cm thickness) are non-combustible (A2-s1,d0) and withstand fire up to 240 minutes (walls) and 180 minutes (roofs). This feature is certified by global standards such as FM Approvals. Fire-resistant panels with densities of 90 to 110 kg/m³ provide excellent thermal insulation (U-value up to 0.17) and sound insulation up to 32 dB, making them the optimal choice for buildings where fire safety is critical.
Decorative Sandwich Panels are available in various designs such as wood, stone, glossy metals, modern textures, and custom colors, allowing the creation of unique and attractive interior and exterior facades. These panels are used in modern and classic building facades, commercial, office, and residential interior decoration, stylish partitioning, and constructing special decorative elements, offering both aesthetic appeal and insulating properties.
The choice of sandwich panel color is typically based on the client’s preference and, in some cases, aligned with the client’s corporate color scheme. Occasionally, roofs are covered using two different colors. However, the most commonly used colors are those shown in the image below.
The foam of a Sandwich Panel is its middle layer and core, which is injected between two metal sheets using a foam injection machine with varying densities. It can be considered the reason behind many of the unique features of a Sandwich Panel. For instance, the type of Sandwich Panel foam determines its thermal insulation performance. Other characteristics, such as fire resistance, are also determined by the type of Sandwich Panel foam. Therefore, selecting the appropriate type of Sandwich Panel foam according to the application and project location is of great importance.
Polyurethane foam (PUR/PIR) with a closed-cell structure provides highly effective thermal and acoustic insulation. This foam is produced in two types: PUR (flame-retardant) and PIR (non-combustible). PIR type has self-extinguishing properties and higher fire resistance. Due to its lightweight, high moisture resistance, and water repellency, Polyurethane foam is used in projects requiring high thermal and acoustic insulation, such as cold storage facilities and industrial halls.
Polystyrene foam or EPS (Expanded Polystyrene) is a lightweight and cost-effective material used as thermal and acoustic insulation in Sandwich Panels. This foam has an open-cell structure and lower fire resistance compared to other foams. However, due to its affordable price and light weight, it is used in projects with limited budgets and moderate insulation requirements, such as temporary buildings and warehouses.
Rock Wool foam is made from mineral fibers and has very high fire resistance. This foam can withstand temperatures up to 1000°C and also provides excellent acoustic insulation. Rock Wool foam is used in projects that require high fire resistance and sound insulation, such as control rooms and conference halls.
Glass Wool foam is made from glass fibers and provides suitable thermal and acoustic insulation properties. This foam is lightweight, flexible, and has good fire resistance. Glass Wool foam is used in projects that require thermal and acoustic insulation with low weight, such as office and residential buildings.
The foam materials used in the sandwich panels by Mammut Structures undergo multiple rigorous testing stages to verify compliance with relevant standards. Upon successful completion, certification is issued based on the test results. You can review the certificate by clicking the link below:
It should be noted that in addition to the type of coating, the weight and thickness of the coating are also of great importance. According to standards, the weight of the Aluzinc or galvanized metal coating should not be less than 100 grams per square meter. It is important to mention that the higher the coating weight, the greater the corrosion resistance will be. This level of coating protects the sheet against environmental corrosive factors such as humidity and rust, thereby increasing the lifespan of the sheet and consequently the Sandwich Panel product.
The price of Sandwich Panels varies depending on the type of materials and the specific features of each model. However, price is only one of the factors that should be considered when choosing a Sandwich Panel. Below, we examine the factors that affect the selling price of Sandwich Panels to help you make the best decision.
