Why Install Two High Speed Doors in One Factory Corridor?
Why Install Two High Speed Doors in One Factory Corridor?
At BAROS, our team installed two high speed roller doors in a factory corridor to help reduce hot air, dust and insect entry while limiting cold air loss from temperature-controlled areas.
Why install two high speed doors when one might seem enough? Each door serves a different purpose. Together, they create an additional barrier that helps factories manage environmental exposure and temperature differences while supporting daily operations.
Why Install Two High Speed Doors in One Corridor?
A double high speed door system uses two separate industrial doors with a buffer space between them. Instead of relying on a single entrance barrier, each door supports a different environmental control requirement.
| Door Position | Main Purpose | Practical Benefit |
|---|---|---|
| Outer Door | Limits hot air, dust and insects | Reduces outside exposure |
| Inner Door | Limits cold air loss | Supports temperature management |
| Buffer Space | Separates two environments | Reduces direct air exchange |
The advantage is not simply having two doors. It is how both doors work together to protect temperature-sensitive areas while allowing regular factory movement.
How Do Two High Speed Doors Work Together?
01
Outer Door – Keep Outside Conditions Outside
The outer high speed door helps reduce unwanted exposure from surrounding factory areas.
It helps limit:
Hot Air
Hot air entering the corridor
Dust and Insects
Dust and insects reaching production areas
Air Exchange
Unnecessary air exchange during daily movement
Its fast opening and closing mechanism reduces the time the entrance remains exposed.
02
Inner Door – Help Keep Cold Air Inside
The inner high speed door separates the corridor from temperature-controlled production areas.
Its main functions include:
Cold Air Retention
Reducing cold air loss during access
Indoor Temperature
Supporting more consistent indoor temperatures
Environmental Barrier
Providing another barrier between factory environments
This arrangement is particularly useful for cold rooms, air-conditioned production spaces and food manufacturing facilities.
03
Both Doors – Additional Protection During Daily Operations
When correctly positioned and operated, two high speed doors create a buffer zone that helps reduce direct air exchange between factory areas. This arrangement offers several practical advantages:
Better Environmental Separation
Closing one door before opening the other helps limit direct exposure.
Additional Barrier
If one door becomes unavailable, the remaining door may still provide some separation, depending on its condition.
Smoother Daily Operations
A suitable arrangement supports regular movement while managing environmental exposure.
At BAROS, we plan door configurations around factory traffic, safety requirements and operational needs.

Which Factories May Benefit from Two High Speed Doors?
Not every factory requires two doors. We recommend considering the arrangement when environmental separation is important.
| Factory Application | Potential Benefit |
|---|---|
| Food Processing Factory | Reduces exposure to dust and insects |
| Cold Room Facility | Limits warm air entry and cold air loss |
| Air-Conditioned Production | Separates different temperature zones |
| Hygiene-Sensitive Manufacturing | Adds a physical environmental barrier |
| High-Traffic Corridor | Supports frequent movement and separation |
Suitability depends on corridor space, traffic frequency, door specifications and operating conditions.
How We Plan Double High Speed Door Installations
At BAROS, we help factories select practical industrial door configurations based on their daily operations.
Our process includes:
01
Site Assessment
Review corridor dimensions, available space and traffic requirements.
02
Door Planning
Determine suitable positions, environmental needs and operating arrangements.
03
Installation
Install both doors and the relevant operating components.
04
Testing & Support
Check door movement and safety functions, with maintenance support available.
Operating since 2008, we provide industrial door design, manufacturing, installation and after-sales technical support across Malaysia.

Two doors create an additional buffer zone. The outer door helps reduce outside exposure, while the inner door helps limit cold air loss from temperature-controlled areas.
They may reduce unnecessary air exchange and cooling demand. Actual savings depend on door usage, sealing, temperature differences and facility conditions.
Not necessarily. Sequential operation can help reduce direct air exchange, but the appropriate control arrangement depends on traffic and safety requirements.
The remaining door may provide some separation if functioning safely. Continued operations depend on the fault and facility requirements.
Yes, if sufficient space and suitable installation conditions are available. Our team can assess the corridor before recommending a configuration.
