That is why you need to know what options are available so you can provide your clients with exactly the right kinds of doors they need.

  • Which interior door type should I choose?

  • What door core should I choose?

This commercial wood interior door buying guide gives you the information you need to know to select the best door for your requirements.

What is the Best Material for Interior Doors?

The door material you choose depends on the industry of your project, and each material for interior doors serves a different purpose. You can explore the benefits of each one to decide which door would be right for your client's project. 

When choosing the door material, think about the use of the door. You can also design a custom door out of any material you choose. A professional door distributor can help you find the right custom door material.

1. Versatile: Wood Door

Verstile wood doors for apartments and hotels - DoorStop

Wood doors offer natural beauty that enhances the aesthetic of any office space. Wood is a reliable material for interior doors because of its resistance to wear and tear. You can also stain or paint wood doors any color.

Manufacturers create flush wood veneer doors with thin layers of wood over a core. Since wood doors are versatile, you can find a wood veneer door to fit your budget. Our wood veneer doors come in a variety of stylish species.

At DoorStop, we offer two unique types of flush wood door finishes:


  • Standard wood veneers: We offer some veneer doors in some popular materials like walnut, birch and oak. You can choose an unfinished or pre-finished wood veneer door depending on your inventory needs.

  • Special wood veneers: We can also create custom doors made from special wood materials, including eucalyptus and fir.


Our wood veneer doors are custom-made to accommodate your clients' design requests. Craft your perfect interior wood veneer door with your choice of veneer, cut and match. Flush wood doors are easy to maintain and cost-effective.


Wood veneer doors are popular in apartment buildings and hotels. Both hotel and apartment staff enjoy their ease of maintenance and variety of design options. Solid wood doors also provide noise reduction for additional privacy in a room.

2. Industrial: Metal Door

Hollow metal material provides a durable, easy-to-maintain door for your office space. We have doors on hand for you to choose, or you can create a custom-made metal door. Our customers enjoy our hollow metal doors because of their:


  • Durability: Metal doors can withstand harsh winds and rains. Within an office space, metal doors are useful in case of an emergency.

  • Safety: Metal doors can protect your clients and their employees from fires and break-ins.

  • Ease of maintenance: Metal doors are damage-resistant so they can last a long time with minimal repairs.

  • Versatility: Metal doors are lightweight but sturdy. Companies use them both inside and outside of their buildings.

  • Insulation: Hollow metal doors insulate against both hot and cold temperatures. They keep your clients' office space comfortable at all times.


Clients install metal doors in high-traffic areas like corporate buildings, offices and hospitals. Companies enjoy lightweight hollow metal doors to provide ease of entry. Areas with high traffic also use metal doors to protect people inside from harm.

3. Traditional: Stile and Rail Door

A stile and rail door employs vertical and horizontal pieces of wood to create a classic look. Stile and rail doors can accommodate your clients' interior commercial space. Customers like our stile and rail doors because of their:

Hotels use stile and rail doors to give their rooms an elegant feel and to make their space feel like home. Libraries or historical societies could also use a stile and rail door for an extra classic look.


Stile and rail doors are adaptable, allowing you to create a classic door for your clients. You can choose window placement and wood placement to allow your door to look how you want.

4. Professional and Clean: Plastic Laminate Door

Plastic laminate doors for hospitals and schools - DoorStop

Plastic laminate doors are useful for high-traffic areas like hospitals and schools. Laminate doors are easy to clean and are resistant to stains and moisture. High-traffic areas that are prone to germs could benefit from these stain-resistant doors.

Plastic laminate doors are both high-quality and affordable. Manufacturers create laminate doors to accommodate any style. Plastic laminate swing doors are popular in hospitals because they allow for more space for patients and equipment.

Our team at DoorStop has a variety of plastic laminate door design options:

  • Linear Graphite: A textured, linear stone pattern with hints of red.

  • Chocolate Ash: A rich, mid-tone wood pattern textured with a charred look.

  • Lost Pine: A knotty wood texture highlighted by gray and taupe.

  • Shadow Ash: A woodgrain pattern adorned with warm gray ash partial cathedrals.

  • Stone Alona: Plain-sliced grain with strong cathedrals in dark gray oak.

  • Planked Texas Walnut: Wood paneling with full cathedrals and light to dark variations.


Manufacturers create laminate by mixing paper and resin into a sturdy sheet. You can have the natural beauty of wood and the affordability of plastic in a plastic laminate door. Each plastic laminate door's core contains fire-retardant material.

Which Interior Door Type Should I Choose?

After choosing the commercial interior door material, think about your client's door type. With custom options available, you can choose any type of door to make from your door material. Here are the most popular types of interior doors for your clients' commercial space.

1. Bypass Door

What is a bypass door? DoorStop bypass doors for hotels

Bypass doors feature two or more offset panels that slide along a track. They stack up behind one another when the door opens. Bypass doors are most often used for bedroom closets. Apartments and hotels would most enjoy this type of door because of its ability to save space.

Bypass doors work like sliding doors. While a sliding door glides along a track on the bottom of the door, a bypass door glides on a track above the door. Since the doors overlap when one door opens, there is no need for the door to swing open.

Use bypass doors in small spaces that don't have a lot of room. A bypass door is useful for storage because it is lightweight, and it reduces space. You can design a bypass door with mirrors to make a room look bigger.

2. Folding Door

Folding doors, or bi-fold doors, open by folding into two panels that jut outwards. You can use this type of door for a closet or an area with limited space. Folding doors are practical for small areas. They allow more access to your closet than bypass doors.

Folding doors are like a combination of swing doors and bypass doors. They use both hinges and an overhead track to move. Folding doors save space and allow for easy access. These doors only take up about half the space of a standard swinging door. You can use a folding door for a closet, a laundry nook or a pantry. Design your folding doors with wood or metal.

3. Hinged Door

Hinged doors, or passage doors, are the most common in commercial and residential buildings. You can install hinged doors either on the left side or the right side of the door frame. Designing a hinged door left-handed or right-handed allows easy access into a room. Hinged doors provide a smooth transition from one room to the other. They offer a wider range of motion than other doors.

You can buy most hinged doors pre-hung and leveled within a frame. Pre-hung hinged doors are easier to install. You can add the frame right to the hallway or room entrance.

You could use a standard hinged door to give privacy to a meeting room. You could also install double-hinged doors to allow space for big furniture. Double-swing doors also create the feeling of a grand entrance.

4. Pocket Doors

What are pocket door styles? Pocket doors for offices - DoorStop

Pocket doors slide along a track under the door and disappear within the wall. Installing them in an existing wall may need some demolition work. They make a great door for privacy in case you need it, and they take up less space than hinged doors.

Pocket doors work great in areas of limited space. They also give privacy to larger spaces like conference rooms. If a staff member has to take a phone call, for example, they can slide the door closed. Since they are versatile in design, you can use pocket doors in any location and for any purpose. You can install either single or double pocket doors for a commercial building.

What Door Core Should I Choose?

The core of an interior door is what is inside the door. You have several options, from solid to hollow core material. These are the types of door cores that we at DoorStop provide.

1. Diet Core

Diet core is a solid core with lightweight materials. Our lightweight core provides the advantages of both solid and hollow cores. It has a lighter average square foot to pounds ratio.

Diet core is easier to use and install than a standard solid core door. Solid wood core doors provide noise reduction and durability at a low price. You can use diet core doors for your corporate office project that needs a lightweight door for daily use.

2. Particleboard

What is wood particle board for doors

Another option for a commercial door with a solid core is particleboard. Made of fibers of recycled wood, our particleboard core is ecological and cost-effective. Particleboard accommodates a wide variety of construction standards for doors.

Both hotels and apartments require a comfortable living environment as well as safety, and particle board is fire-rated up to 20 minutes. Since particleboard is affordable and accessible, it is a great choice for your hotel or apartment door.

3. Structural Composite Lumber (SCL)

SCL core contains a combination of wood and laminate. This core made of both plastic and wood is stronger than particleboard. Solid wood core doors are effective at reducing noise and providing privacy at an affordable price. SCL is fire-rated at 20 minutes. You could use SCL doors in hospitals that require strong doors for protection and damage-resistance.

4. Fire-Rated

Fire rated doors for hospitals - DoorStop

A fire-rated core allows any of the doors in our collection to be resistant to fire. We have fire-rated cores rated for 90, 60, 45 and 20 minutes. Mineral core is a non-combustible material we use for our fire-rated doors.

For a material to be fire-rated, it must pass harsh smoke, pressure and flame tests. Each of these fire-rated core doors contains material that has been rated to accommodate your fire-resistance needs. Fire-rated doors are useful for solid wood core doors.

Hospitals and apartment buildings need to meet certain fire requirements for their interior doors. Our fire-rated doors are sure to comply with your project's construction standards.

5. Honeycomb

Standard hollow doors contain corrugated material in 4-inch by 4-inch hexagonal cells. This pattern resembles a honeycomb and provides a lightweight door while maintaining structure. Hollow core doors are only used for interior doors.

Hollow cores use fewer materials, so a honeycomb door core is more cost-effective than other types of core. Hollow door cores are more affordable, lighter and more attractive than solid wood doors. Since they are lighter, they are easier to install and transport.

A hollow core door is a great option for interior doors or areas with low traffic because of their ease of use.

What Door Hardware Do I Need?

Hardware is what makes your door open and close, and it should make your door of choice look and function better. Follow this commercial door hardware guide to explore what we offer at DoorStop.

Door hardware options - DoorStop

1. Hinges and Pivots

Pivots and hinges move the door along the frame. Hinges are the most common way that manufacturers hang a commercial interior door. Manufacturers use five- or three-knuckle hinges for heavy traffic commercial door applications. You can use pivots to mount the door if it is heavy. Pivots are also more attractive than hinges, so your client may prefer the look of pivots on the door.

Hinges are effective for bypass doors and folding doors. As you consider whether to use hinges or pivots, remember to choose a handling side. Put the hinges on whichever side you are going to use to open the door. For example, if you want to open the door with your left hand, put the hinges on the left side of the door.

2. Locks

An effective, secure lock will complete the functionality of your door. We offer a wide supply of commercial locks at DoorStop. Whether you need a simple mechanic lock or a high-tech electrified lock, we have what you need!

Our most popular commercial lock products are:


  • Deadbolt: A deadbolt lock is the most common type of commercial lock. You use a key to lock from the outside and a thumb turn-in to lock from the inside.

  • Tubular: A tubular lock involves a latch that locks into the door. For commercial doors, you use a key to lock from the outside and a knob to lock from the inside.

  • Interconnected: An interconnected lock includes two key-activated locks — one on top of the other. You use a key to lock both locks from the outside and a thumb turn-in to lock both locks from the inside.

  • Mortise: Designers cut a mortise lock into a hinged door. To make a mortise lock, designers insert the latch of the lock inside the edge of the door.

3. Door Closers

If you have a manual door, you can use door closers to help the door come to a complete close. Consider the following qualities to help you choose a door closer:


  • Durability

  • Rate of closing

  • Aesthetics

  • Safety

  • Tamper-proof capabilities

  • Resistance to opening forces


We offer a variety of door closers, including:


  • Surface-mounted closers

  • Concealed closers

  • Floor closers

  • Electric closers

  • High-security closers


Each type of door closer we offer provides different benefits and features. Contact our team to find a door closer for your client's door.

4. Door Protection

Interior commercial doors offer safety, security, privacy, functionality and accessibility for your company. As such a valuable investment for your client, you want to protect your door and prolong its lifespan. We offer several types of protection for your door to guard against wear and tear.

Our door protection inventory includes:


  • Protective plates: Kickplates guard your door against scuffs and dents. You can design your door's kickplate to complement your existing hardware.

  • Edge guards: Like kickplates, edge guards protect your door from dents. They can also cover up existing dents. Edge guards can fit any door size.

  • Gasketing: Door gaskets seal the perimeter of your door jamb. Gasketing helps with sound control, smoke and fire control and light infiltration.

  • Push plates: Push plates protect doors — especially wooden doors — from wear and tear due to excessive use. They are usually installed on the push side of the door.

What Size Interior Door Will You Need?

Your interior door should be the right size for your commercial space. Interior doors often come in standard sizes. Each size accommodates a different function for your client's commercial space.

If you need a door for a frame with a unique shape, we can create custom doors for you and your clients. Here are the standard sizes for most doors:


  • Height of 8 feet and 8 inches: The standard height for a passage door is 8 feet and 8 inches. A passage door is an interior door that leads from one room to the other. You could use a standard passage door in an apartment room or an office.

  • Height of 8 feet and 6 inches: These shorter doors are useful for closet and utility doors. You could also use them for bathroom doors in any commercial building.

  • Width of 2 feet 8 inches: The standard width for a passage door is 2 feet 8 inches.

  • Width of 2 feet 4 inches or 2 feet 6 inches: For a bathroom door, a closet or a utility door, some manufacturers offer more narrow doors.

  • Width of 3 feet: Doors that are 3 feet wide are for wheelchair-accessible commercial spaces.


To decide what type of door you need, measure the door frame first. Here are the steps to obtain the proper measurements:


  • With the door opened, measure from the inside of one door jamb to the inside of the other door jamb. For measuring a slab door, measure the length, width and height of the door itself, not the door jamb.

  • Measure from the inside top of the jamb to the floor. Subtract 3/4 inch from this measurement for floor allowance.

  • Measure the thickness of the door frame.
