The growing demand for cost-effective doors which separates the work environment effectively while reducing heating and cutting energy costs has now led to the popularity of strip doors. Every company, whether it is involved in production or marketing, can introduce strip doors in their workplaces to promote better workflow and a comfortable environment.

This PVC in your doorways has several benefits in the workflow of any company. All walk-in coolers or freezers created on or after January 2009 should compulsorily have strip doors, spring-hinged doors, or other techniques of lessening infiltration when doors are open. It is no longer a rule of thumb, it is the law.

There are many advantages to having a strip door in the work environment such as restriction from the air pollutants, isolating noise, increasing employee comfort, letting natural light in your work office, etc. However, in this discussion, we will be discussing on your total economic impact of having the strip door cost-effectively.

How is the Strip Door Cost-effective?

There is no exact standard measure or a formula to calculate how much return on investment you can obtain from installing strip doors in your workplace but it is undoubtedly a cost-effective investment depending on the scale of your business. If your workplace consists of a cleanroom that is opened every 30 seconds then the loss that your cooler has to make up for those countless times of opening and closing of the doors is costing you. So, it’s time to rethink these lost energies and have the strip doors implanted in your workplace.

However, if the cleanroom or your workplace has the PVC Strip Doors installed then these strip doors can prevent up to 85% of air loss in comparison to the conventional doors. During the time the conventional doors are left ajar, the strip doors ensure easy access through for both people and vehicles.

The cost-effectiveness of the PVC Strips

Unlike the doors, these PVC strips won’t stand in your way as it is not meant to. Its sole intent is to let you enter the workspace with minimum surface area opened while entering. The strip doors help in reducing the amount of heated or cooled air which are usually lost through unnoticed openings in the workplace. It is numerically figured out that the strip door can successfully block 70% of the air passing through the doorway which ultimately helps in saving energy.

Also, the PVC strip doors cost way lower than the conventional doors. But the fact that this strip door lets minimum entry point for anything, be it a person or a vehicle. The minimum infiltration has its benefits by letting the minimum cost to be recuperated by the air conditioner.

Concurrently, the feasibility to customize your preferred door along with its mobility helps you in moving these doors to a new workplace if necessary. This is another plus point for reducing costs in the long haul.

How to calculate the Total Energy Loss?

If you are still unsure of how much energy you have already lost with those conventional doors then here is an example on calculating your energy loss and how much one could have saved if one installs a strip door in their workplace.

  • While calculating the total energy loss, several factors should be considered.
  • First and foremost is the approximate heat or temperature loss through the open doorway
  • Second is how much energy generated the lost conditioned air
  • Thirdly, it is the money spent on the lost energy by your air conditioner
  • Finally, how much money you could have saved if you had PVC strips as doors

For reference, you can use this method to ascertain the total energy lost in British Thermal Unit (BTU) standard.

  1. First of all, calculate the door’s size (in feet). For that, multiply the door’s height and width (W*H). You will get its result in Square Feet (Sq Ft).
  2. Next, calculate the Average Wind Speed of your facility. For that, Multiply the Miles Per Hour (MPH) and 88. You will get the result in Feet Per Minute (FPM).
  3. After calculating these two variables, we can calculate Cubic Feet Per Minute (CFPM). For that, you will need to multiply the door’s size we just calculated in point no.1 and the average wind speed we calculated in point no.2.
  4. Now, you can calculate the Temperature Differential (TD). It is quite simple. For this, just subtract the outdoors’ temperature (in Fahrenheit) from indoors’ temperature (in Fahrenheit).
  5. Now, to calculate the Hourly BTU Loss, multiply CFPM, TD, and 1.08. CFPMxTDx1.08= Hourly BTU Loss (Hr BTU).
  6. Next, you can calculate Daily BTU Loss easily. For that, just multiply Hr BTU and the number of hours the freezer’s door is open. This way, you can ascertain the Daily BTU Loss (Dy BTU).

Lastly, the bigger picture of the strip door is more than just cost-effectiveness. These doors have become the most economical solution to every workplace along with countless benefits which we have mentioned in our several blogs.
