WHAT IS CLEAR OPENING OF A COLD-ROOM DOOR, AND WHY IS IT IMPORTANT?
In this article, we will talk about the size of the cold – room door itself. Firstly, we will determine what cold – room door’s rough opening is. Secondly, we’ll define the clear opening of the cold – room door. Finally, we will explain what to consider when ordering a cold – room door to ensure the smooth construction of your cold – room. We think this topic is essential as it often creates confusion among installers and suppliers of cold-room doors.
Frequently, the confusion occurs between the idea of clear opening and rough opening of a cold-room door.
WHAT IS ROUGH OPENING OF A COLD – ROOM DOOR?
A cold-room door’s rough opening is the clear opening plus the cold-room door’s frame and counter-frame.
WHAT IS CLEAR OPENING OF A COLD-ROOM DOOR?
We consider that clear opening is the available space for passing once the door is fully open. Suppliers consider that the clear opening size of a cold-room door is what matters most.
In other words, when preparing a cold-room door order, it’s better to focus only on the height and the width that we require free for passing. The supplier will take that size and provide you with the cold-room that fits your requirements.
CLEAR OPENING VS SIZE OF THE BLADE OF THE DOOR
I’ve also frequently experienced confusion between clear opening and the size of the blade of the door itself.
Let’s consider a determined clear opening: every supplier produces a different blade size to fit the same size of the clear opening. These differences occur due to different assembling systems. For example, the frame size or the position of the heater can be different.
An important factor here is working temperature: the cold-room door blade of a blast freezer will be larger than the one of a cooler, even if they share the same clear opening.
The reason is that for ultra-low temperature, a cold-room door needs extra space to bear a double perimeter gasket.
Now you know what the clear opening of the cold-room door is. Also, you know the difference between the refrigeration door’s rough and clear opening. It will help you to avoid misunderstandings and mistakes when ordering a cold – room door.
