2. Panel Structure and Insulation

The structure and insulation of cleanroom panels in biologics facilities play a significant role in ensuring that the controlled environment remains stable and meets the stringent requirements for temperature, humidity, and air quality. Below is an explanation of the two main types of panel structures commonly used in biologics cleanrooms: sandwich panels and non-insulated panels.

1. Sandwich Panels

• Structure:
  • A sandwich panel consists of a core material (e.g., PIR (Polyisocyanurate), PUR (Polyurethane), or EPS (Expanded Polystyrene)) sandwiched between two layers of rigid surfaces, typically made of steel, aluminum, or other durable materials.
  • The core material provides the insulation, while the external layers offer strength, durability, and a smooth surface for easy cleaning and sterilization.
• Core Materials:
  • PIR (Polyisocyanurate): Known for its high thermal efficiency and low thermal conductivity, PIR is commonly used in biologics cleanroom panels. It offers excellent insulation properties, helping to maintain the required temperature for potentially temperature-sensitive biologics products.
  • PUR (Polyurethane): Like PIR, PUR offers good insulation properties and is commonly used in environments where temperature regulation is essential. It’s also effective at maintaining energy efficiency within the facility.
  • EPS (Expanded Polystyrene) is another core material used in sandwich panels. It provides an effective but cost-efficient thermal insulation option. While EPS offers good thermal insulation, it is typically less efficient than PIR and PUR and may not be ideal for high-performance environments.
• Advantages:
  • Thermal Insulation: Sandwich panels are essential in biologics facilities that require precise temperature control. The core material’s insulation properties help maintain stable internal temperatures, crucial for biologics manufacturing, storage, and research.

  • Energy Efficiency: Sandwich panels’ high insulation properties help reduce energy consumption by maintaining the desired internal temperature, thus contributing to a facility’s overall energy efficiency.
  • Durability & Cleanability: The external layers (steel or aluminum) provide a durable surface that resists corrosion, impacts, and contamination, making it easier to maintain a clean, sterile environment.
• Challenges:
  • Cost: Sandwich panels can be more expensive than non-insulated panels due to the added insulation material and manufacturing complexity. However, the long-term benefits, especially regarding energy savings and temperature control, often outweigh the initial investment.
  • Weight: Sandwich panels can be relatively heavy, particularly those with thicker cores or heavy-duty materials. This may require additional structural support during installation.
  • Moisture Management: While sandwich panels provide great thermal insulation, they must be carefully sealed to prevent moisture from entering the core, which could lead to mold growth or degradation of the insulation material.

2. Non-Insulated Panels

• Structure:
  • Non-insulated panels are typically made from a single material or a thin layer without an insulating core. They are often used in areas where insulation is not as critical, such as general storage rooms, hallways, or equipment areas.
  • The external material could be steel, aluminum, or other durable materials, but it would not have the thermal or acoustic insulating properties of sandwich panels.
• Advantages:
  • Cost-Effective: Non-insulated panels are generally less expensive than sandwich panels, making them suitable for areas of the biologics facility where insulation is unnecessary. For example, non-insulated panels may provide sufficient protection without thermal insulation in low-risk areas.
  • Lightweight: These panels tend to be lighter than sandwich panels, reducing the overall load on the structure and making installation easier and faster.
  • Simple Design: Non-insulated panels are simpler in design, which may make them more versatile and easier to modify or reconfigure if needed.
• Challenges:
  • Limited Thermal and Acoustic Insulation: Non-insulated panels do not provide the same thermal regulation or noise reduction level as sandwich panels. This can be problematic in biologics facilities where temperature and environmental control are essential.
  • Potential for Increased Energy Costs: Without insulation, non-insulated panels can generate higher energy consumption because the facility’s HVAC system will have to work harder to maintain temperature and humidity levels, especially in temperature-sensitive areas.
  • Limited Use in Temperature-Sensitive Areas: Non-insulated panels are unsuitable for areas that require precise temperature control, such as production areas, storage areas for temperature-sensitive biologics, and cleanrooms where sterility and environmental conditions must be carefully managed.

3. Cleanability

Cleanability is one of the most critical aspects of choosing cleanroom panels for biologics facilities. These facilities must adhere to strict cleanliness and sterility standards to ensure the safety and efficacy of biologics products. The design and materials of the panels must facilitate frequent cleaning and sterilization without compromising their integrity or performance. Here’s a closer look at key features related to the cleanability of panels in biologics facilities:

1. Smooth, Non-Porous Surfaces
