Door Material Quality

How can you tell if a door is made from quality material? The criteria for quality material depend on the material. There are various types of door materials, which include laminate, veneer and paint grade. Each type comes with unique specifications that cater to a specific budget and audience.

Laminate wood door quality


For an affordable, versatile door option, you may want to consider a laminate door. Decorative laminate doors have consistent, durable designs that make them a popular option for commercial or high-traffic spaces, such as schools and hospitals.

The following are benefits of laminate doors:

  • Affordable: Because laminate doors are made from simple yet sturdy materials, manufacturers can offer distributors laminate doors that are affordable. Laminate doors provide a similar appearance to stone or wood doors at a more affordable price.
  • Durable: Laminate tends to be more durable than wood veneer. Laminate is also resistant to scratches, heat and stains in spaces involving dirt or liquids.
  • Easy to maintain: Laminate doors tend to have surfaces that are easier to clean than wood doors. Cleaning a laminate door is as simple as using a soft, damp cloth. Laminate doors also do not need oil and require minimal maintenance.
  • Versatile: Distributors can select from a wide range of designs for a laminate door to match the theme and decor of a space. Laminate door manufacturers offer patterns like stone, wood and solid colors.
  • Weather-resistant: Materials in laminate doors ensure that the doors will not warp when the weather or humidity changes. Laminate doors remain the same shape and size regardless of the season.

At Manhattan Door, we design our flush plastic laminate doors to ensure durability through high-frequency use. These doors can be designed in customized sizes up to 48 inches by 120 inches and are fire-rated up to 90 minutes. Additionally, we offer a wide variety of design options to tailor laminate door, including wood grains, solid colors, abstract patterns and styles. Our laminate doors can be installed in several different work environments, such as offices, warehouses, municipal buildings, retail centers, auto shops and more.

How can you tell if the laminate is quality laminate? Check the door material. The material should not produce an unpleasant odor, the frame should be level, and there should not be any visible dents or scratches. You can also check the accessories to ensure all the elements are fastened securely.

Wood Veneer

If you want an affordable door option without sacrificing beauty, veneer interior wood doors may be the right option for you. The following are the benefits of wood veneer doors:

  • Quality: The quality of wood veneer doors is comparable to the quality of other types of doors. For high-quality veneer doors, materials come from prime sources.
  • Variety of options: Veneer doors are available with solid or hollow cores. Solid core doors feature a combination of engineered wood and natural wood veneer that are fused together to create a heavy fiberboard. This type is suitable for restricting sounds and providing better security. Hollow cores are sourced from paperboard or laminated wood. These doors often come with honeycomb cardboard, which is covered in veneer to improve structural integrity.
  • Aesthetically pleasing: Wood veneer doors stand out. They bring a look of class and elegance that are highly appealing to the eye, and wood veneer’s aesthetic appeal makes it a common choice among architects and designers. Distributors who value aesthetic appeal may want to consider a wood door.
  • Flexible: The versatility of wood veneer doors adds up to its growing popularity. You can style the wood in several ways, from contoured style to curved surfaces. Because of varying designs and beautiful patterns, this gives wood veneers an edge in terms of flexibility.
  • Durable: Doors in high-traffic areas are subjected to a lot of wear and tear. As such, doors must be as durable as possible. Fortunately, when properly maintained, wood veneer doors are among the most durable doors. These doors can avoid scratches, dings and dents.
  • Insulative: Wood veneer doors can be quite insulative, allowing little cold and heat to enter a building. These doors can prevent drafts and reduce energy bills.
  • Eco-friendly: Sustainability is a core element in wood manufacturing. Due to the lesser wood composition, wood veneers cut fewer trees, making them more sustainable than solid wood. Other companies also upcycle reclaimed wood to create veneers and minimize carbon footprint.

Wood veneer can provide excellent quality, durability and insulation. These doors can be made from various types of wood, such as oak, cherry, mahogany, maple and walnut. Additionally, you may want to select a wood veneer door that has a durable stain and a clear finish. A finish can prevent your door from absorbing moisture or swelling.

Common veneer cuts include:

  • Rotary
  • Plain sliced
  • Quarter
  • Rift cut

Our veneer doors are manufactured to your specifications, which includes customizing your door to fit the exact opening size. Select any common or specialty species of wood or a certain factory finish for an attractive and distinct professional appearance. Wood veneer doors can offer visual appeal and lasting performance at a cost-effective rate. Many wood veneer doors are corporate settingshotels and hospitality venues.

How can you tell if the veneer is high quality? During quality control, veneer doors are inspected for knots or rot sections. Other materials used during construction must also meet certain standards of quality, such as the glue and stains. A quality veneer door should keep swinging for years and resist warping.

To determine if the wood is high quality, you can first check the package integrity, looking for opened or torn packaging. You can also compare your door to the presented model and examine the heat and sound insulation.

Paint Grade

Wood doors are also available in paint grade. Here are some of the benefits of paint grade doors:

  • Match existing decor: Maybe you want to match your door to your upholstery, carpet or interior paint. Paint grade doors allow you to create the perfect color scheme.
  • Additional protection: A quality primer protects soft woods and medium-density fiberboard (MDF) doors before they are installed.
  • Versatile: Paint grade doors are extremely versatile. Doors of the same shape can look surprisingly different when painted in different colors.
  • Easy to update: With a paint grade door, all it takes is a new coat of paint to refresh a door or change the feel of an entire room.
  • Easy to maintain: Painted doors tend to be easy to clean, depending on the paint finish. Cleaning a painted door often requires just a wet cloth and some soapy water.

At Manhattan Door, our paint grade options can complement any interior design. We use a fast-drying, water-based latex primer that works well in both exterior and interior applications. With all of our options, you can add a clean, professional paint grade door to any building.

Door core types

Door Core Quality

Are solid core doors worth it? Or should you select a hollow core door? Solid core and hollow core doors differ in insulation, sturdiness, sound blocking and maintenance. Knowing how a door is constructed is helpful when it comes to decorating or making repairs.

Solid core doors are constructed from natural wood and synthetic material, and they more closely mimic real wood than hollow core doors. While hollow core doors tend to be a more affordable option, they are less durable than solid core doors.

We at Manhattan Door offer the following types of interior door cores:

  • Hollow core honeycomb: Honeycomb cores are made of corrugated fiberboard that gives a door structure while also saving money. Check out our spec sheet to learn more about honeycomb cores.
  • “Diet” core: Our unique “diet” core doors offer more structure than hollow core doors and are lighter than solid core doors. Check out our spec sheet to learn more about “diet” cores.
  • Fire-rated: To meet building regulations, fire-rated commercial doors can be designed for a rating of 20, 45, 60 or 90 minutes. Learn more about the specs of our 20-minute fire-rated doors45-minute fire-rated doors and 60-minute and 90-minute fire-rated doors.
  • Particleboard: Another type of interior door core is particleboard. Particleboard is a cost-effective, durable core. Learn more from our spec sheet on particleboard core doors.
  • Structural composite lumber core: In a structural composite lumber core, different species of wood are held together by resin. Structural composite lumber core remains affordable while also offering more structure than particleboard. Learn more from our spec sheet on structural composite lumber cores.

How to tell if a door is solid or hollow

How to Tell If a Door Is Solid or Hollow

Use the following guidelines to determine if a door is solid or hollow:

1. Test the Door’s Weight

If the door is new and has not been hung yet, you can test it by how easily you lift the door. For a door that is already attached, you can swing it open and closed to test the inertia. Hollow core doors can be lifted and swung quite easily, while solid core doors are quite a bit heavier and will be more difficult to lift. If the door requires minimal effort to lift or swing, there is a high chance that it is a hollow core door. If the door requires more effort to lift or swing, it is probably a solid core door.

2. Check the Door’s Paneling

If there is paneling on the door, it may help you determine whether a door is solid core or hollow core. Hollow core doors tend to have faux panels, and a close examination can tell you whether the panels are imitations. If the panels on the door appear real and detailed, then it is likely a solid core door.

3. Examine the Door’s Finish

The finish on a door can also help you determine whether the door is hollow core or solid core. Hollow core doors are not often stained by manufacturers, except for veneer doors. If a wood door is stained, then it is more likely that the door is solid core than hollow core, particularly if the door is heavy. If the door is painted, then it is likely a hollow core door.

4. Consider the Price of the Door

Hollow core doors tend to be less expensive than solid core doors. Prices can vary by manufacturer and location, so speak to a salesperson who can give you an idea of the price points you can expect for different door cores. Solid core doors typically have a higher price point because of the resources used as well as the detailed construction process. As a result, solid core doors are sturdier while providing more insulation and security.

5. Check the Condition of the Door

A solid core door uses denser materials, which makes it more durable than a hollow core door. The solid construction of solid core doors also impacts its life span. If a wood door has dents or holes from normal wear and tear, then it is likely a hollow core door. If the door does not have any damage, this does not necessarily mean it is definitely a solid core door, but damage likely means it is a hollow core door.

Door Hardware Quality

Hardware for a door serves multiple purposes, including adding beauty, securing a property and providing convenience. The following are different hardware types for doors:

Doorknobs and Levers

Doorknobs and levers are necessary for opening, closing and securing a door. A latch in the doorknob disengages when the knob is turned. When the doorknob is locked, the latch cannot be disengaged from the outside unless a key is used. A door can be locked and unlocked with the thumb turned on the inside of the knob. Some doorknobs have locks that can be disengaged when the inside knob is turned, and others feature a push-button that can lock the door on the inside.

Door levers are intended for easy operation, as they do not need to be grasped and twisted like doorknobs. Instead of a lever, the user needs to only push down the lever to disengage the latch. Locking a lever prevents anyone from disengaging the latch from the outside unless a key is used. Door levers can also be right-handed, left-handed or universal.


Handlesets can add a decorative touch to a door. These include a thumb-operated latch, a deadbolt and an exterior handle. Similar to door levers, handlesets can be found with left-handed, right-handed and universal levers. The deadbolt of the handleset can be either single-cylinder or double-cylinder. Nonfunctional handsets are also available to complement a double door’s functional hardware. A handleset can give a door more elegance compared to the average deadbolt and doorknob or door lever.


Deadbolts are another type of door hardware. When paired with a locking doorknob or door lever, a deadbolt functions as another locking point. A deadbolt can provide an additional security measure and more peace of mind. Deadbolts are available as either single-cylinder or double-cylinder.
