Resources & FAQ


What is the order process and lead time?

Please see our note below detailing the order process and billing information.

Am I limited to the design and material choices I see on your website?
Absolutely not, we strive to meet your needs and fulfill your vision for your elevator cab renovation. We work with you throughout the process to generate a distinctive, yet affordable product.
Do my elevator mechanics need to be involved?
Usually the only time your elevator company needs to get involved is in the event the door needs to be pulled to re-clad with stainless steel or bronze.
What are the benefits of one material over another?
Each material holds its own value and purpose. For further explanation please visit our Materials and Finishes page to learn more.
My building is high traffic, what is the best material for me?
For high traffic buildings we recommend incorporating satin or patterned stainless steel into your design. Our ‘Systems 3 & 4’ provide unmatched form and function, fostering timelessness, strength, and beauty.
I am on a budget, what are my options?
Selecting our vertical plastic laminate panels are a pleasing, affordable option that can add the distinct, updated touch you are looking for. Virtually all colors, styles, and finishes for plastic laminates are in the same price range so the choice is yours.
How will my order be shipped?
Your order will generally be shipped via Yellow Freight or a carrier of your choice.
Do you have green options?
Yes, we are proud to offer GreenLam recycled plastic laminate as an alternative to newly sourced laminates. Please see below for a note on Imperial’s environmental policy.
What is the billing process?
Please see the explanation of our order process below which includes information about billing and taxes.
What is your warranty policy?
We are proud to back our work for one year and will make repairs within that year at no charge.
Why do I need to measure each cab, can’t I send you original drawings?
As cabs age, the walls can flex and become out of square. If you are filling out the online order form, we ask that you measure each cab within 1/16th inch accuracy.
What is a canopy?
The canopy is the ceiling of your elevator cab.
What are my options for flooring?
Options range from granite to radial rubber tile flooring to carpet depending on your need for durability and/ or style.
What is the installation process and how long does it take?
Please see information below for detailed installation instructions. The process can vary depending on your design but typically takes several hours.
Can I get larger material samples?
Absolutely, we understand it can be difficult to make a final decision without seeing and touching the material. Please call our design team and we can order one or several of your choices.
My low voltage halogen bulbs need to be replaced, can I order replacement bulbs from you?
Yes, you are welcome to order bulbs through us or you can visit as well.
Can I get drawings of the design plans?
Yes, part of our approval process involves having shop drawings reviewed and approved by you.
What are my choices for panel design and material options and colors?
Please see our Materials and Finishes page for further descriptions of each material as well as links to see the array of colors, patterns, and finishes.
Should I be concerned about adding weight?
Not necessarily, we tend to take out as much weight as we put back in. The panel cores are made from a light weight MDF board. Sometimes adding materials like stone can add additional weight, though we can discuss this with you as it arises. It’s always a good policy to consult your elevator maintenance contractor.

Order Process

If you are using our online order form, please complete with each page initialed by a supervisor and fax, mail, or email it to us for review. Our design team will promptly review your order to ensure accuracy and will send you a quote for your approval. Your satisfaction is our top priority, so please choose with confidence.
Once approved, you will receive a contract. Shop drawings will be drafted once we have received the signed contract.

Fabrication will begin after we have received the approved shop drawings and a 50% deposit.
Finally, shipment or installation. Your balance is due prior to shipment. With your order you will receive all the necessary hardware as well as installation instructions.
This process can advance with your rapid response. The lead time on some materials is longer than others. We can provide that information as is arises.

Accurate Measuring

You will be responsible for accurate measurements when completing the online order form, so your precision is encouraged.
Measure the inside dimensions of each cab on the jobsite within 1/16th inch accuracy. Measurements should indicate the shell size without panels.
Do not rely on original drawings or the measurements of one cab, often with age walls can flex and change slightly in size.


Imperial Interiors is committed to conducting our business in a responsible, proactive manner. We are always on board with sustainable efforts within our industry, though we understand you can’t always wait for others to step up. We make every effort to handle and dispose of waste properly, conserve resources, and minimize waste through proper planning. Our skilled staff is free to use any off- cuts for reuse or repurposing. Energy efficiency is encouraged and recycling of office, shop, and shipping materials is a priority. Imperial is currently working on gaining LEED Certification status. The most sustainable material choice for paneling is our newly available GreenLam plastic laminates made from recycled materials. Our panel cores are always MDF, which has greatly improved its environmental impact over the years. It is now made in large part from recycled materials as well as off cuts from mills. We have switched to a low-VOC adhesive which produces far less off-gassing than traditional glue. We believe that small steps can add up to something big.


Elevator Cab Maintenance:

Plastic laminate and natural wood finishes in elevator should be maintained with mild soap and water. Use of spray wax such as Pledge should be avoided as this type of product tends to build up on the finished surfaces. Abrasive cleaners and pads should never be used on your decorative surface. Water-based cleaners and polishes are the best option. In the case of a woodgrain, always clean and polish in the direction of the grain.

Scuff marks from shoes or ink marker can be removed with Naphtha; which is available at your local hardware store. After the marks are removed, the surface should be cleaned and polished, as Naphtha will leave a slight residue on the panel. DO NOT use chemicals such as Acetone, Methyl Ethel Ketone or Lacquer Thinner on your wood panels as these solvents will harm the finish. Bronze metal that has a lacquer finish should be treated the same as natural wood.

Stainless steel should be cleaned on a regular basis using a water-based stainless steel polish such as the cleaner from 3M. Petroleum based cleaners will produce a build up of product on the metal, leaving cloudy streaks. Mild surface scratches can be removed with a 3M Scotch Brite pad. Always work the pad in the direction of the grain in the metal. DO NOT try this solution with mirrored stainless steel. Scratches in mirror finished metal need to be professionally repaired. All stainless steel finishes should be professional cleaned and regrained on a regular basis, every 12 to 24 months based upon the elevator usage.

Bronze metal, either satin or polished, requires more maintenance. If left unmaintained, bronze with start to tarnish or oxidize. Bronze needs to be cleaned and a clear lacquer coating applied for the metal to remain top condition. The maintenance of bronze needs to be done by a professional metal maintenance contractor. Depending upon usage, this work would need to be done every 18 to 36 months.

Establishing a regular maintenance schedule for your elevator will keep your cabs in a condition that you and your building occupants will be proud of.



Our standard recessed downlight is a 3” diameter low voltage 20 watt Halogen fixture. The fixtures are pre-harnessed to the system power pack, which houses the system dimmer. The input wattage of the Halogen is the same as many other 20 watt low voltage systems, but the output or candlepower is up to 4 times stronger. Therefore a 6 lamp Halogen system will have the same light level as other system using up to 24 mini-lights. A typical size elevator would use 6 Halogen fixtures. The fixtures are a standard power coated black with other finishes available.

An LED lighting option is available. The LED uses the same 3” fixture as the Halogen, each with 3 – 3 watt LED’s for a total of 9 watts per fixture. This energy efficient light will provide years of reliable service with out the cost of bulb replacement or the labor to change them. Each 9 watt LED fixture provides light levels equal to one – 20 watt Halogen, a 50R20 - 120 volt incandescent or a 26 watt compact fluorescent. Our warm white LED produces natural coloring to the cab interior, not the normal blue-white commonly associated with white LED’s.

An emergency light package option can be supplied as part of either the Halogen or LED systems. Typically the two fixtures near the car operating panel will be activated upon a power failure. The emergency light power supply is pre-harnessed to plug directly into the fixtures, and meets A17.1 emergency light codes.


Wall Panel Installation Instructions:

  • Remove existing handrails, panels and reveals, or any other material on the elevator walls exposing the structural cab surface.
  • Establish a flat, level floor line as the baseline to set your story poles. Use the markings on the story poles and establish corresponding marks on the cab walls, both vertically and horizontally. At the same time mark the wall for the location of the reveal strips.
  • Set each clip within your marks and screw each clip to the wall with two screws.
  • Double check the sizes of the reveals strips by “dry fitting” them. Trim if necessary. Use construction adhesive at the established locations from your story poles.
  • Set the panels in place by engaging the by-parting clips. Double check the reveal spacing prior to fully engaging the panels.
  • Lay-out the attachment points for the handrails and predrill a 13/64” hole for the enclosed fasteners. Attached the removable spacers to the cab wall and engage the handrails bar, tightening the set screws in the spacers.
