Hardwall vs. Softwall Cleanrooms

Cleanrooms are a crucial component in various industries such as pharmaceuticals, biotechnology, and electronics manufacturing. They maintain a highly controlled environment to prevent contamination of products or processes. Choosing the right materials for your cleanroom is essential for ensuring optimal performance and compliance with regulatory standards. In this article, we delve into the differences between hardwall and softwall cleanrooms, helping you make an informed decision.

A Brief Introduction to Cleanrooms

Cleanrooms are classified based on their cleanliness level, as determined by the number of particles and contaminants present in the air. The International Organization for Standardization (ISO) classifies cleanrooms into various classes, with ISO Class 1 being the cleanest and ISO Class 9 being the least clean. Choosing the right materials and construction for your cleanroom is essential for meeting these cleanliness standards.

Hardwall Cleanrooms: Features and Benefits

Hardwall cleanrooms are characterized by their rigid wall panels made from materials such as stainless steel, acrylic, or high-density polyethylene (HDPE). These cleanrooms offer the following benefits:

Enhanced Durability:

Hardwall cleanrooms are built to withstand the test of time. Their robust construction ensures they can handle heavy equipment, resist damage, and maintain structural integrity for many years.

Improved Cleanliness:

Hardwall cleanrooms provide a higher level of cleanliness due to their non-porous and easily cleanable surfaces. The rigid wall panels minimize particle generation and prevent contaminants from infiltrating the cleanroom.


Hardwall cleanrooms can be tailored to meet specific requirements. They can accommodate various ceiling heights, HVAC systems, and air filtration configurations to suit different industry needs.

Softwall Cleanrooms: Features and Benefits

Softwall cleanrooms, also known as portable cleanrooms, feature flexible, transparent curtains or vinyl walls. They offer the following advantages:


Softwall cleanrooms are typically less expensive than hardwall cleanrooms. Their simple design and easy installation result in lower upfront costs.


Softwall cleanrooms are known for their adaptability. They can be easily expanded, reconfigured, or relocated based on changing requirements or production needs.

Rapid Deployment:

Softwall cleanrooms can be quickly assembled and disassembled, making them ideal for short-term projects or temporary installations.

Comparison of Hardwall and Softwall Cleanrooms

Feature Hardwall Cleanroom Softwall Cleanroom
Durability High Moderate
Cleanliness High Moderate
Customizability High Low
Cost High Low
Flexibility Moderate High
Deployment Speed Low High

Selecting the Right Material for Your Cleanroom

When deciding between hardwall and softwall cleanrooms, consider the following factors:

Industry Requirements:

Assess the specific cleanliness and regulatory standards required for your industry. Hardwall cleanrooms are generally better suited for highly regulated industries such as pharmaceutical and aerospace, while softwall cleanrooms may be suitable for less stringent environments like research labs.


Analyze your available budget for constructing and maintaining the cleanroom. Softwall cleanrooms typically have lower initial costs, but hardwall cleanrooms may offer better long-term value due to their durability and efficiency.

Space Constraints:

Evaluate the available space for your cleanroom and consider potential future expansions or reconfigurations. Softwall cleanrooms offer greater flexibility in terms of size and layout, while hardwall cleanrooms require more careful planning and construction.

Project Timeline:

Determine the timeline for your cleanroom project. If you need a cleanroom solution quickly, softwall cleanrooms can be rapidly deployed. On the other hand, hardwall cleanrooms generally require more time for planning, construction, and commissioning.

Equipment Requirements:

Consider the type of equipment that will be used within the cleanroom. Hardwall cleanrooms can accommodate heavy machinery and provide better support for infrastructure such as HVAC systems, while softwall cleanrooms are better suited for lighter equipment and more straightforward configurations.

Choosing the Right Provider

After selecting the appropriate material for you cleanroom, it is important to select a provider who is able to meet your needs and has extensive experience in the field. Instant Cleanroom Solutions provides both hardwall and softwall options that are tailored to any operation. If a hardwall solution is what you require, ICS provides both the Mobile Cleanroom — specialized for short term rental situations and rapidly expanding manufacturing — and the Modular Cleanroom — a long term, permanent solution. Both are able to adjust to your changing needs, although the Modular Cleanroom provides full, top-down customization to meet your specific configuration.

The Instant Cleanroom is a revolutionary softwall solution pioneered by ICS to be the most rapidly deploy-able cleanroom on the market. Capable of being setup in under 4 hours, the Instant Cleanroom provides a temporary or seasonal environment that can certify down to ISO 5. Relying on preexisting climate control, the Instant Cleanroom is the fastest and most cost-effective way to incorporate a cleanroom into you operations.


Selecting the best material for your cleanroom is a crucial decision that requires careful consideration of your industry requirements, budget, space constraints, project timeline, and equipment needs. Both hardwall and softwall cleanrooms have their advantages and disadvantages, so it's essential to weigh these factors before making a choice. By making an informed decision, you can ensure that your cleanroom will effectively meet your needs and promote the success of your business in the long run.
