The material used for the core of the door must be light in weight and at the same time, have a high flexural strength.
Coating materials must allow an easy cleaning, high resistance and durability.
Cleanroom doors are a crucial part as they are responsible for sealing off the controlled environment. According to ISO 14644-1, “in manufacturing or scientific research environments, a cleanroom is an environment with low levels of contamination (dust, microbes, aerosol particles or chemical vapours) and in which other relevant parameters, such as temperature, humidity and pressure, are controlled as required”.

There are several points that are worth considering when choosing pharmaceutical doors. Although it is always convenient to consult with a specialist technician who attends to our specific case, we leave you with 4 basic points:
The surfaces of all the elements of a clean room must be completely resistant to water and not produce chemical reactions with the use of soaps, disinfectants and other cleaning products for daily use. On the other hand, the materials must be highly durable and have adequate reaction to fire behaviour. In addition, they must allow good usability and easy maintenance.
SICH Clean Rooms doors comply with ISO standards insofar as, due to their design and materials, they maintain the cleaning standards required in a clean room environment.
The design of the SICH Clean Rooms doors is flat on both sides and is flush with the panel. And attention should not only be paid to the surface and materials of the door, but also to the rest of the elements that make it up such as hinges, locks, handles, windows… All of them must be designed and installed in such a way that it allows easy access for the cleaning and, at the same time, prevent the accumulation of dust, dirt or grease.
Another of the critical points in the construction of clean environments is to guarantee an optimal seal . Keeping the space free of cross-contamination is crucial to ensure the quality of the plant’s output.
The goal of doors in a clean room, ultimately, is to maintain cleanliness by ensuring a high level of tightness .
SICH Clean Room hinged doors for clean rooms are completely flush and maintain watertightness due to the continuous perimeter seal placed throughout the door frame and another automatic one at the bottom of the door.

Another of the critical points in the construction of clean environments is to guarantee an optimal seal. Keeping the space free of cross-contamination is crucial to ensure the quality of the plant’s output.
The goal of doors in a clean room, ultimately, is to maintain cleanliness by ensuring a high level of tightness.
SICH Clean Room hinged doors for clean rooms are completely flush and maintain watertightness due to the continuous perimeter seal placed throughout the door frame and another automatic one at the bottom of the door.
Our door coatings are made from 3mm thick phenolic resin boards (HPL). HPL resin is an ideal material for the construction of clean rooms since, as it lacks porosity, it prevents the proliferation of microorganisms such as bacteria and viruses.
The core of the SICH Clean Rooms doors is made of 54 mm thick polystyrene, which provides sufficient resistance, lightness and, at the same time, flexibility.
The doors have been specifically designed to prevent the accumulation of dust and allow easy and effective cleaning and disinfection. On the other hand, the material has high durability and resistance to impacts or scratches. Optionally, a stainless steel sheet can be added.
They are fitted with extruded aluminum frames integrated into the panel that guarantee robustness and lightness at the same time. The electrical part (such as the interlocking system, traffic light, button panel or buzzer) is integrated into the whole, maintaining the same concept.
Based on our experience in the design and construction of clean rooms and following current regulations, we have standardized the following free passage sizes for our doors, but they can be manufactured to order in any dimension and colour:
800mm x 2200 for the simple ones.
800mm x 4000mm for the doubles.
Being products made of lightweight materials, not only are transport and assembly easier, but they are also more sustainable by reducing the carbon footprint.
There is the possibility of incorporating optional accessories such as: traffic lights, alarms, emergency bars or anti-panic bars, automatic weather stripping, locks, automatic access controls (fingerprint, non-touch, card, scanner facial…), peepholes and windows with anti-condensation system, electrical and magnetic interlocks, motors, external and hidden door closer arms, protections…
Thanks to our experience and knowledge in the execution of projects for the pharmaceutical industry, we have developed our own modular system for the construction of clean rooms. The set includes doors, windows, profiles, paneling, lighting, ceilings, PassBox, Benches for SAS… In short, all the necessary elements for the comprehensive design and construction of pharmaceutical plants and clean rooms.
The SICH Clean Rooms hygienic enclosure system is made of high-quality materials that do not release particles and allow easy cleaning. This system reduces the complexity of the pharmaceutical installation and ensures that it meets the requirements of ISO14644 and GMP classification. .

Double-opening steel clean room door
Before a clean room is functional, it would need more accessories. You need to install clean room doors, windows, benches, sinks, and so much more. This guide mostly focuses on the clean room doors and how you can make a great choice for your clean room. Let us see what clean room doors are all about.
Figure 1 Sliding Clean Room Doors
Take a clean room door like any other door you know about. The only difference is that this door would be made to seal the controlled clean area. If the door does not work as expected, you are easy to end up with more contamination in a clean room. So, the clean room door manufacturers have to take their time to come up with high-quality clean room doors that can do a good job of keeping the contaminants out.
It is why you might get these doors having seals crucial for maintaining an airtight clean room door. The best part is that most manufacturers would allow for the customization of the clean room door so that it can work great for all your needs.
If you are going to end up with the best clean room door, it is best to understand the common production process. In most cases, it could involve assembling the crucial clean room door materials. These materials would ensure that you end up with a highly functional clean room door.
Add sealing strip for clean room door window
Like for Sunnyda, the company uses a 1.0mm thick galvanized steel material. This material is important for making the door panels. Once everything is set up on the door including the core material, the thickness can go up to 50mm. This is the thickest you can get in most cases.
As for the core material, manufacturers often use paper nests or aluminum nests. These materials are known for their thermal insulation. This is important to keep the temperatures in the clean room within the desired range.
If you hope to get the best fire rating performance, go for rock wool material. This material is also important for keeping the fire contained in case there is an outbreak. The same material is also good at keeping the noise down. So, if you want the best sound insulation in a clean room, consider rock wool as the core material.
The door panels are mostly made of 1.2mm galvanized steel or powder-coated steel. The same material can be great for the door frame. Keep in mind that the door frame and panel thickness will be mostly based on the clean room wall thickness.
Once the doors and frames are produced, they have to go through different inspections to ensure they are working as expected. The last thing a manufacturer wants is complaints from the client that the door is not sealing correctly.
Whether you are looking to start a new project of clean room doors or you need to replace the existing clean room doors, there are many options available. Just make sure to take your time to consult even further before settling for one clean room door manufacturer.
Figure 2 Hinged Clean Room Doors
As the name suggests, clean room doors need to deliver on the performance expected for a clean room. This means it needs to provide an easy entrance into the clean room while at the same time prevent contamination where necessary.
So, which clean room types could use clean room doors? Well, it should be all clean room levels. Keep in mind that the clean room levels vary a lot. They are mostly based on the cleanliness level. They are also classified from ISO1 to ISO 8.
ISO 1 clean rooms are the cleanest and mostly used in industries such as life sciences and electronics. To help maintain their level of cleanliness, these clean rooms will have an average air change of 500 to 760 per hour. As for IS0 8 clean rooms, the air change is 5 to 60 per hour. It is easy to see how clean room doors for ISO 1 and ISO 8 clean rooms would be different. One needs to be better to help maintain the overall cleanliness of the clean room.
Clean room doors can be made of many materials. However, the most common options are galvanized steel and powder-coated steel. These materials are loved because of their overall performance against corrosion and keeping the clean room doors strong generally.
The biggest difference between galvanized steel and powder-coated steel is how the protection works. For galvanization, the surface will absorb the corrosive materials before they reach the steel material. As for powder coating, it provides a protective barrier that keeps the destructive materials from easily penetrating the surface.
The choice between the two options is mostly based on the cost. Galvanized steel would always offer low maintenance costs over the years. However, if the powder coating is done right, it can also have the best durability for years.
As for the core materials, you have the option of aluminum nests and paper nests. You could still get rock wool or EPS where fire resistance is important to further protect your clean room in case of a fire outbreak.
Stainless steel and steel clean room door
When you are buying clean room doors, you are likely to come across different types of materials used in the production process. Stainless steel is a top choice. The most common stainless steel grade is 304, 316, and 201. So, what is the difference between these materials and where best can you use them?
Grade 304
This is the most common type of stainless steel. It is a general-purpose material. That is why you are likely to come across it even in your house. It is often used to make kitchen utensils, appliances, and so much more.
It also contains higher levels of nickel content than the other grades of stainless steel. This nickel component can make the steel less susceptible to cases of corrosion.
Most people find it generally affordable. It is why it would also be a great choice for those on a budget and need clean room doors.
Grade 201
The prices of nickel important for making grade 304 raised the prices of such a grade of stainless steel. It is why grade 201 was developed. It led to cheaper stainless steel that would replace 304 while at the same time keep the prices down.
As much as it is a cheaper option, it still works great for various environments. It is known to have higher levels of manganese that makes it stronger and great for cold environments.
Since it does not have much nickel, it is not very effective at preventing corrosion. So, in case your clean room would be a highly corrosive environment, this would not be the best option for you.
Grade 316
This is the top-tier grade to get if you have highly corrosive environments. It has the highest nickel component. It is expected that it would cost more because of its compounds. However, the cost is still worth every penny.
The 316 also has molybdenum that the 304 lacks. This is crucial for fighting corrosion. It is why you would use such clean room doors for areas with chloride and saline exposure.
Now that you know the differences between these materials, let the choice be based on the applications. In cases where you would have more corrosion agents, it is best to spend extra and get the clean room door made of grade 316 stainless steel.

Figure 3 Using Clean Room Doors
Different manufacturers would have different types of clean room doors. However, most of them fall under the following types of clean room doors.
Manual door opening
Automatic door opening
Manual sliding door
Fast door
Rolling door
There can be many other types available. It comes down to what you need as the best clean room doors. This is mostly because the manufacturers can add more accessories to the doors to improve their operations. A good example is the automatic doors. They would have multiple accessories crucial for making it easier to open and close the door. Also, they can help in minimizing cases of contamination.
Yes. The clean room doors serve an important role of maintaining the performance of the clean room. It is why the manufacturer would ensure the doors are high strength, durable, and have good sealing effects. Also, the doors can be adapted to different environments where clean room doors might be necessary.
A good feature of most clean room doors to help maintain clean room class level is having a self-lifting sealing strip. This strip is important for aligning itself so that it can blow air from the outside from getting into the clean area. Generally, you should have confidence that your clean room level would be maintained better.
Round and square vision window for clean room door
Having the best clean room doors can help a lot in making sure your clean room works great. It is why you may want to keep the following factors in mind when picking the best clean room door.
Flush fitting
Flush fitting is something important for any clean room accessory. It is not just the clean room doors, but also the windows, and much more. Flush installation means that the doors can remain flat with clean room wall panels. This will help meet the compliance standards and keep the clean room clean.
Ease of integration
In this case, it is the way you install the clean room door. It should be designed to be for installation and also compatible with the various wall systems already existing. There is no doubt you should have an easy time installing the clean room doors once the manufacturer understands what kind of wall system you have. Also, the size is important. Not all clean room door spaces would be the same size. Tell the manufacturer about the size of the door so that you can get the right size.
Resistant to most cleaning chemicals
Clean rooms sometimes have to be cleaned using strong chemicals. This is because of the need for maintaining high levels of cleanliness. In such a case, the materials used to make the clean room doors should be good enough to withstand the use of strong cleaning chemicals. The best part is that most manufacturers would use stainless steel that can withstand such chemicals. More research might be necessary to find the best clean room door material.
Impact-resistant
Depending on the type of clean room and operations inside, sometimes there can be more traffic in and out of the clean room. It is because of such traffic that you would want to ensure that you get a model with the best impact resistance. It should also be highly durable so that it can stay useful for many years down the line.
Price
Another thing you have to keep in mind is the price. We all know that clean room accessories are not the cheapest. This is because they have to be adapted to suit the needs of the clean room. Even if you expect to spend more on a clean room door, it should be worth the price. This might mean checking out the features of the clean room door to see if it is worth the price.
Figure 4 Installing Clean Room Door Frame
Rollup clean room doors are the latest trend in clean room door manufacturing. This might be because the clean room has decreased footprint and it still needs a clean room door. So, the rollup door might be a nice choice to consider generally.
The new generation rollup doors will have anti-microbial materials and other cleanroom upgrades. These features are crucial to make the roll-up clean room doors good for different clean rooms.
They would also have tight sealing and high cycle speeds for making them suitable for various clean room types. Even with their roll-up mechanism, they can still be fast to minimize air intrusion while at the same time increase productivity.
So, if you are ever in the market for a different design for a clean room door, this one is still a great option to consider.
The cost of clean room doors varies a lot based on the manufacturer, accessories, design, and so much more. It is why there are times you may have to pay more. However, on average, the price will range from $100 to over $1000, depending on the customizations. Always take your time to check out the different clean room doors to understand the possible price. Also, get quotes from various suppliers and choose the competitive quote based on the features of the clean room doors.
Stainless steel clean room door with frame
When you are buying clean room doors, one thing that will be different from the regular doors is the hinges. The clean room door hinges are designed to work great in clean area while at the same time limit or prevent cases of particle emissions.
In most cases, the metals used in making these hinges will not have particle contamination. The best part is that these hinges would also be kept smooth, easy to move, and so much more. The chances of squeaks are kept to a minimum as much as possible. Still, some would have plastic bushings important to prevent any cases of minute dust particles that might affect the clean area.
Like any other door hinge, the clean room door hinge is also likely to get squeaky with time. When this happens, it is advisable to get yourself some lubricating oil crucial for improving the performance of the clean room door.
There are several options you will have when looking to improve the performance of your door hinge. You could use hinge oil, white lithium grease, or silicone spray. Silicone spray is probably the easiest to use, but it will not have a long-lasting effect as grease. Use the spray properly to minimize the mess.
Sometimes you may have a rusty hinge. Such a hinge would need proper lubrication to keep it working great. Using door hinge oil should be good to quiet it down with little effort. If the rust is too deep, you may have to use penetrating oil to get deep into the hinge.

The list above is just a few of the accessories you can get with clean room doors. They can be more depending on the clean room door manufacturer.
Color options for clean room door
You can always get different color options. You are likely to be limited by your imagination. This is because most manufacturers allow the users to customize the color for powder coating the stainless steel doors. You may opt for colors that would be great for your overall company color theme. So, the color options should never be an issue when looking for the best clean room doors.
You could say that the biggest difference is the opening mechanism. The manual clean room doors mostly need the user to push them manually to open. This means more people would be touching the clean room door. As such, there is the risk of more contamination. It is why more clean rooms are switching to automatic clean room doors.
With the automatic clean room doors, you will have the option of opening the doors using sensors or buttons. Some doors can sense when you are close to the doors and open automatically. This is important to reduce the need for worrying about more contamination when more people are using the same clean room door all the time.
As part of customizing the clean room door, you have the option of adding a window into the door. The window can be great for checking out the different operations going on in the clean room. Most of the time, the window would be made of tempered glass. However, there can be other materials depending on the client’s needs.
As you can see, clean room doors are crucial for any clean room to have today. Go ahead to ensure that the clean room door comes from a top brand. It gives you the assurance you are buying a high-quality clean room door. If you have any more questions, talk to Sunnyda for more details. The customer support team is ready to help you further.
This Door system is widely applied to hospitals, medical centers, clean rooms and electronic factories. We use 304 stainless steel panle with honey comb insert to make clean room door. There are two interts which are paper honeycomb and aluminium honey comb. In order to prevent dusts, we have added a brush seal on the bottom. The door could be operated with interlock system which is much safer than ordinary types.
Congratulations – you are building a cleanroom. It is important to choose the correct quantity and type of cleanroom doors so your cleanroom will function well.
These cleanroom gown room doors will be the most used doors in the cleanroom. They are typically kept as small as possible (3 ft wide) to limit the amount of contaminated air that can enter the cleanroom. Swing doors should have door closers to make sure the doors close when not in use. The cleanroom gown room doors can be interlocked to electronically make sure that only one door can be open at a time. For high-traffic cleanrooms, motorized sliding doors are often used to provide hands-free operation. However, the high cost of motorized sliding doors ($20k-$30k each) limits their usage.
Figure 1: Cleanroom swing door Figure 2: Cleanroom aluminum store front doorCleanroom equipment transfer doors are typically large doors that open directly to the outside to allow large equipment to be brought directly into the cleanrooms. Options for modular cleanrooms include manual cleanroom double swing doors varying from standard 6’x7’ to custom 8’x8’. For larger equipment, motorized roll up doors as large as 16’x16’ can be installed in cleanrooms albeit at high cost.
Figure 3. cleanroom motorized roll up door Figure 4: Custom extra large double doorManual Sliding doors are sometimes used in cleanrooms due to space restrictions. By installing a sliding door, we avoid using up space for the door swing. Disadvantages of manual sliding doors is they leak significantly more air than cleanroom swing doors and they do not last as long. There also needs to be space for the door to slide into when in open position. Motorized sliding doors are more durable but are very expensive.
Figure 5: Cleanroom manual sliding door Figure 6: Cleanroom motorized sliding doorMaterial transfer rooms are airlocks where incoming material can be wiped down prior to bringing material into the cleanroom. These rooms typically have either large cleanroom double doors or motorized roll up doors to allow palleted material to be either forklifted or manually pallet jacked into the room. The motorized rollup doors are sometimes equipped with sensors so they will open automatically for forklifts. When automatic door openers are used then the doors must be equipment with interlocks to ensure that both doors are not open at same time.
Rather than carrying material in and out thru gown rooms, pass thru’s are often installed in cleanrooms. They are typically 2’x2’x2’, though any size is possible with 2 doors. The doors are mechanically interlocked so only one can be opened at a time, thus limiting the amount of contaminants that can enter the cleanroom. The doors are typically clear acrylic or glass so personnel can see if there is something in the pass thru. Pass thru’s are most commonly made from plastic laminate but can also be made from stainless steel (very expensive). Sometimes a HEPA fan filter unit is part of the pass thru to further reduce contaminants entering the cleanroom thru the pass thru. Another type of pass thru is a cart pass thru that sits on the floor and is designed to allow carts of material to be brought into cleanroom.
