When planning a building upgrade, commercial interior doors are often overlooked, but they are one of the most impactful ways to improve an existing space.

This is not because you are starting from scratch, but because you are working within what already exists and trying to enhance performance, aesthetics, compliance, and tenant experience without a full rebuild.

At first glance, the decision may seem simple: glass, wood, or metal. In renovation projects, especially in occupied or aging buildings, it becomes far more strategic.

Interior office doors do more than separate spaces. They influence privacy, acoustics, durability, safety compliance, visibility, and even how modern a space feels.

So instead of asking, “What door should I pick?”, the better question is:

What issue in my building am I trying to solve, and which door solution helps me fix it most effectively?

Start With the Problem, Not the Product

Before selecting materials, successful renovations begin by identifying what is not

Door swing direction is one of the most common points of confusion when ordering a commercial door. It is also one of the easiest things to get right once you know what to look for.

The challenge is that small mistakes can lead to ordering the wrong door, delaying installation, or even failing inspection. Understanding door swing direction early makes the entire ordering process smoother.

What Is Door Swing Direction?

Door swing direction refers to the side of the hinges and the direction the door opens. In commercial doors, this is classified as left-hand (LH), right-hand (RH), left-hand reverse (LHR), or right-hand reverse (RHR).

Once you understand how these are determined, identifying the correct swing becomes straightforward.

How to Determine Door Swing Direction

To determine the door swing direction, stand on the hinge side of the door. If it swings left, it is left-hand. If it swings right, it is right-hand.

• Stand on the hinge side of the door

• If the door swings to your left, it

When you see terms like steel building doors, commercial fire rated doors, or hurricane proof doors, you’re not just looking at product categories—you’re looking at solutions built for specific risks, codes, and environments.

That’s what defines a specialty door.

At CDF Distributors, specialty doors are designed around real-world performance, not just standard sizing or appearance. Each type exists to solve a specific problem that a typical door cannot.

What Are Specialty Doors?

Specialty doors are engineered for performance requirements beyond standard use. In commercial construction, doors are often part of a larger system tied to safety, compliance, and long-term durability. A standard door might close an opening, but a specialty door is designed to perform under pressure—literally and figuratively.

You’ll typically see specialty doors used when a project calls for:

• Preassembled metal building doors (commonly referred to as steel building doors) for exterior commercial structures

When you’re ordering commercial double doors or exterior steel double doors, the last thing you want is a damaged shipment slowing down your project. At CDF Distributors, we understand that these doors aren’t just pieces of steel—they’re investments in safety, security, and smooth daily operations.

Choosing the correct door handing, also called door swing, is a critical part of specifying fire rated double doors. Door handing affects how the doors operate, how hardware is applied, and whether the opening meets fire and life safety requirements. For commercial double doors, including exterior steel double doors and interior fire-rated openings, understanding handing helps avoid installation errors, inspection failures, and costly rework.

Whether you are specifying a double door fire rated opening for a corridor, stairwell, or exterior wall, door handing must work in coordination with fire-rated hardware. Below is a clear breakdown of the most common handing options used for a double fire door and how each functions.
