Smooth and Seamless Surfaces: Cleanroom sandwich panels feature smooth, seamless surfaces that prevent the accumulation of dust, bacteria, and other contaminants. This characteristic facilitates easy cleaning and helps maintain a sterile environment, which is essential for cleanrooms. The use of wall sandwich panels in these structures is a common and professional choice due to their cohesive and hygienic design.
High Resistance to Moisture and Water: These panels are engineered to have high resistance to moisture and water, ensuring optimal performance in environments where hygiene and humidity control are critical.
Strong Thermal and Acoustic Insulation: Cleanroom sandwich panels include thermal insulation layers that reduce temperature exchange and maintain desired conditions inside the room. They also provide adequate acoustic insulation, which helps minimize noise in the environment.
Resistance to Chemicals and Disinfectants: Cleanroom panels are highly resistant to chemicals, disinfectants, and strong cleaning agents. This is a crucial feature, as disinfecting agents are frequently used to maintain sterility in these environments, and the panels must not be damaged by them.
Resistance to Bacterial and Fungal Growth: A key characteristic of cleanroom sandwich panels is their high resistance to the growth of bacteria and fungi. They are typically made from antibacterial materials that prevent the proliferation and spread of microorganisms.
Precise Airflow Control: These panels are designed to effectively control airflow, which is essential for maintaining positive or negative pressure within the cleanroom. This control helps prevent the entry or exit of contaminants.
Resistance to Abrasion and Corrosion: The panels are usually constructed from materials like galvanized steel or aluminum, which offer high resistance to abrasion and corrosion. This feature is particularly beneficial in environments with high humidity or the presence of chemical substances.
Before making a decision to purchase cleanroom sandwich panels, understanding their applications will lead to a more precise and cost-effective choice. Due to their structural features and hygienic standards, these panels are used in numerous industries, and this diversity in application directly impacts the price of cleanroom sandwich panels.
Some of the most important applications include:
When purchasing cleanroom sandwich panels, it is essential to consider the specific application, the required cleanliness level, the materials to be used, and the project’s approved standards.

Advantages of Consulting with Mammut Experts








Cleanroom sandwich panels are manufactured in various types, including polyurethane core, polystyrene, and rock wool. Each type features specific technical properties related to insulation, weight, durability, and application. Below, we thoroughly examine the specifications and differences of each type.
Polyurethane (PU) Core Cleanroom Panels
Polyurethane core cleanroom sandwich panels are among the most common options for cleanroom construction due to their high density (approximately 40–42 kg/m³), providing excellent thermal and acoustic insulation. These panels have a low thermal conductivity coefficient (around 0.022 W/m²K) and demonstrate strong resistance to moisture, mold, and corrosion. Available thicknesses typically range from 4 to 10 cm, facilitating easy installation and lightweight handling, which reduces installation costs. The smooth and washable surface makes this product ideal for hygienic and sterile environments.
Rock Wool Core Cleanroom Panels
Rock wool core cleanroom sandwich panels offer an ideal solution for projects requiring high fire resistance, strong sound insulation, and compliance with stringent hygiene standards. These panels have a density between 100 and 120 kg/m³ and provide good thermal resistance (thermal conductivity coefficient approximately 0.04 W/m²K). They can resist fire for up to 2 hours, comply with EN 13501 standards, and their modular installation system enables fast and flawless project delivery. Rock wool cleanroom panels are produced according to detailed engineering datasheets, which are available upon request.
Aluzinc Antibacterial Coated Cleanroom Panels
Cleanroom panels coated with antibacterial aluzinc are specialized choices for sensitive hygienic spaces such as operating rooms, pharmaceutical industries, and food production lines. The antibacterial aluzinc coating, composed of aluminum and zinc, is finished with a special layer to prevent microorganism growth.
These panels exhibit high resistance to corrosion, moisture, and chemicals, making them a reliable option for clients seeking durability and high quality in hygienic projects. They are sterilizable, feature a smooth surface resistant to scratches, and fully comply with GMP and HACCP standards, making them an excellent choice for consulting engineers. Easy installation, uniform appearance, and low maintenance costs make these panels an efficient solution for contractors and project executors.
Stainless Steel Sheet Cleanroom Panels (For High Humidity Conditions)
Cleanroom panels with stainless steel sheets offer a professional solution for environments exposed to high humidity, corrosive substances, or frequent cleaning such as pharmaceutical cleanrooms, laboratories, industrial cold storage, and food production plants. Stainless steel sheets (grades such as 304 or 316) provide exceptional resistance to rust, chemicals, and temperature variations.
The smooth and professional surface of stainless steel cleanroom panels complies with stringent GMP, FDA, and ISO standards. Their high durability and suitability for special conditions make them an ideal choice for project owners and consultants requiring high-quality surface control.
