Crown Mouldings
Crown mouldings are decorative architectural trim installed where walls meet ceilings. They create a finished transition while adding character, depth, and architectural detail to any room.
Popular applications include living rooms, dining rooms, bedrooms, kitchens, hallways, offices, finished basements, condominiums, and commercial interiors.
LED Light Coves & Cove Lighting
LED light-cove mouldings conceal LED strip lighting and create indirect illumination. The effect depends on the moulding, LED position, brightness and room finishes. Test the proposed layout from normal viewing positions.
Compare the profile drawings and samples to choose a moulding that suits your room and lighting plan.
Coffered Ceilings & Waffle Ceilings
Coffered ceilings consist of decorative recessed ceiling panels framed by beams or mouldings. They create architectural depth, visual interest, and a luxury appearance that transforms ordinary ceilings into premium design features.
Waffle ceilings are a type of coffered ceiling featuring symmetrical grid patterns that add dimension and structure to interior spaces.
Decorative Ceiling Beams
Decorative ceiling beams add architectural character and visual structure to rooms. They can be incorporated into coffered ceiling systems or installed independently to create farmhouse, traditional, transitional, or contemporary design styles.

Nu Crown Mouldings — Product and Planning Questions
Browse answers about crown mouldings, LED light coves, coffered ceiling planning, and ordering.
Crown mouldings
What rooms should have crown mouldings?
Common applications include living rooms, dining rooms, bedrooms, hallways, kitchens, offices, and finished basements.
Are crown mouldings suitable for modern homes?
Yes. Modern crown mouldings typically feature cleaner lines and simpler profiles that complement contemporary interiors.
Are crown mouldings suitable for traditional homes?
Yes. Traditional crown mouldings often incorporate multiple curves, steps, and decorative details inspired by classical architecture.
What are Styrofoam crown mouldings?
Foam crown mouldings use an expanded polystyrene, or EPS, core. Nu Crown mouldings have a plaster-based coating. Check the selected product information for its dimensions and finish.
What are foam crown mouldings?
Foam crown mouldings are lightweight decorative profiles used at wall-to-ceiling transitions. Nu Crown profiles combine a foam core with a plaster-based coating and can be finished using the published installation guidance.
Are foam crown mouldings durable?
Handle and install the selected moulding according to the installation guide. Crown mouldings have a manufacturer’s lifetime warranty for specified manufacturing defects. Ask for the full terms to check which products and types of damage are covered.
Why choose EPS crown mouldings?
The foam core makes the mouldings lightweight to handle, and the plaster coating provides a finishable surface. Compare the product dimensions, installation requirements and delivered cost with the alternatives for your project.
Are EPS mouldings better than MDF?
Compare the selected EPS and MDF products by shape, weight, finish, installation needs and the conditions in your room. Use each product’s specifications to help you choose; neither material is the best choice for every room.
Are EPS mouldings better than wood?
Compare foam and wood mouldings by size, weight, finish, installation needs and the conditions in your room. Follow each product’s instructions for attaching the mouldings and finishing the joints. Ask for product-specific advice if joint movement is a concern.
Can crown mouldings be painted?
Yes. The crown moulding installation guide covers sanding and painting the finished installation. Follow its paint recommendations and check compatibility with the selected moulding and any joint-finishing materials.
What color should crown mouldings be?
Choose a colour that works with the ceiling, walls and other trim. White, a matching ceiling colour or a contrasting trim colour are design options; the best choice depends on the room and lighting.
What crown moulding size is best?
The ideal size depends on ceiling height, room dimensions, and design preferences.
What size moulding works for 8-foot ceilings?
Use the product dimensions and drawings to compare how much of the wall and ceiling the moulding will cover. A sample can help you judge its size in your 8-foot room. Consider the room’s proportions as well as the ceiling height.
What size moulding works for 9-foot ceilings?
Compare the moulding’s wall and ceiling dimensions with the room proportions and other trim. Use a sample to judge its size at a 9-foot ceiling; choose for the whole room, not just a fixed size range.
What size moulding works for 10-foot ceilings?
For a 10-foot ceiling, compare larger and smaller profiles using their drawings and a sample. Room width, existing trim and the desired visual effect also influence the choice.
Are crown mouldings suitable for kitchens?
For a kitchen, check the chosen moulding, the space around cabinets, the surface it will attach to and the room conditions before installing it.
Are crown mouldings suitable for bathrooms?
Ask Nu Crown whether the chosen moulding and finishing materials suit your bathroom or powder room, especially where moisture is a concern.
Are crown mouldings suitable for basements?
For a finished basement, compare the moulding dimensions with the available ceiling height. Check the surface it will attach to and the room conditions. Ask Nu Crown whether the product is suitable if moisture is a concern.
How are crown mouldings installed?
Follow the crown moulding installation guide for measuring, cutting, fitting, attaching and finishing. Use the adhesive and joint materials recommended for the chosen moulding and the surface it will attach to. Check compatibility before using a construction adhesive.
Can homeowners install crown mouldings?
If you have the right tools and skills, use the crown moulding installation guide to assess the work. Complex corners, difficult surfaces and related electrical work may need professional help.
What tools are needed for installation?
The crown moulding installation guide lists measuring, cutting and finishing tools and materials. Check that list for the selected installation, including the recommended adhesive or fixing method and joint-finishing materials.
How are corners cut?
Measure the actual corner and use the cutting method shown in the installation guide. Test the fit before fixing the pieces; room corners are not always exactly square.
How are moulding joints finished?
Follow the installation guide for fitting and finishing joints, sanding and painting. Careful preparation, fitting and finishing are important to the final appearance; a seamless result is not guaranteed.
Do crown mouldings come with a warranty?
Crown mouldings have a manufacturer’s lifetime warranty for defects in materials and manufacturing, including the coating defects described on the homepage. Contact Nu Crown for the full terms, the products and defects covered, and how to make a claim.
LED light coves
What are LED light coves?
LED light coves are decorative moulding profiles used to conceal LED strip lighting and create indirect illumination. Compare the LC-01–LC-08 profiles in our LED light cove mouldings collection, then check the profile drawings before choosing a moulding.
What is cove lighting?
Cove lighting is an indirect lighting technique where light is reflected from ceilings or walls rather than shining directly into a room.
What is indirect ceiling lighting?
Cove lighting uses a concealed light source to illuminate the ceiling or upper wall indirectly.
What are the benefits of LED cove lighting?
A light cove can conceal the LED strip, highlight the ceiling and add an indirect lighting effect. Energy use, dimming and colour options depend on the LED system you select. Test the layout from normal viewing positions before finishing it.
Is cove lighting energy efficient?
Energy use depends on the LED strip, power supply, total installed length and controls. Compare the selected system’s input power and light output; the moulding itself does not determine energy consumption.
What rooms benefit most from cove lighting?
Light coves can be considered for living rooms, bedrooms, dining rooms, hallways and home offices. Check the selected profile, ceiling or bulkhead arrangement and the lighting needed for the room. Plan separate lighting for tasks where needed.
Is cove lighting suitable for living rooms?
A light cove can add indirect ambient lighting to a living room. Compare the profile with the ceiling layout and test it alongside the room’s other lighting.
Is cove lighting suitable for bedrooms?
A light cove can add indirect lighting to a bedroom. Choose the shade of white light and any dimming controls from the selected LED system, then test the effect in the room.
Is cove lighting suitable for dining rooms?
A light cove can be used with other dining-room lighting. Check how the indirect light works with the table lighting and the room’s finishes.
Is cove lighting suitable for kitchens?
Cove lighting can add general background lighting to a kitchen. Plan lighting for work surfaces separately, and choose mouldings and LED components suitable for the actual installation conditions.
Is cove lighting suitable for home theatres?
Cove lighting can add general background lighting to a home theatre. Test the proposed brightness and position from the seating area and check for reflections on the screen.
Is cove lighting suitable for commercial projects?
Light coves may form part of a commercial lighting design. Have the project team confirm the moulding, finish, mounting details and electrical system against the requirements of the specific space before ordering.
What LED strips are compatible with light coves?
Check the selected moulding drawing against the LED strip and any channel used to hold it. Compare their dimensions and follow the lighting manufacturer’s mounting instructions. Ask Nu Crown to confirm the proposed arrangement before ordering.
Can RGB LED strips be used?
Colour-changing (RGB) LED strips can be used when the selected lighting system and controller support them and suit the cove installation. Confirm the features and shade of white light you want before choosing the system.
Can smart lighting be integrated?
Smart control depends on the LED system and controller you select. Check compatibility with your intended app or smart-home platform before purchase.
Can cove lighting be dimmed?
Dimming depends on the selected LED strip, power supply and compatible controls. Check the lighting manufacturer’s dimming instructions and test the system before finishing the cove.
What color temperature should I choose?
Choose colour temperature for the white-light appearance you prefer: 2700K and 3000K look warmer, while 4000K looks cooler. Compare an actual lighting sample with your finishes and check light output separately.
What is 2700K lighting?
2700K provides a warm, cozy glow often used in bedrooms and living rooms.
What is 3000K lighting?
3000K is a warm-looking white light that is slightly cooler in appearance than 2700K. Colour temperature does not specify brightness; compare the LED product’s light output separately.
What is 4000K lighting?
4000K is a cooler-looking white light than 2700K or 3000K. Choose it for its colour appearance and compare the LED product’s light output separately.
Are LEDs visible in cove lighting systems?
The cove is intended to conceal the LED strip. Visibility depends on the profile, mounting position and viewing angle, so test the proposed arrangement from seated and standing positions before finishing it.
Where is the LED strip installed?
In the arrangement shown in our cove-lighting guide, the strip sits on a suitable support behind the moulding with the LEDs facing upward. Confirm how it will be mounted and how much space it needs for your chosen moulding and lighting system. Leave access for maintenance and repairs.
Are LED light coves paintable?
Yes. Follow the moulding installation guide and the paint manufacturer’s instructions. Confirm that the finish is suitable for the moulding; the published technical guide prohibits urethane-based finish coats.
Do LED light coves come with a warranty?
Nu Crown lists a manufacturer’s lifetime warranty for defects in materials and manufacturing. Ask for the full warranty and confirm that it covers your selected light cove before ordering.
How do I choose the right LED light cove?
Compare the LC-01–LC-08 drawings and a sample where available. Check the ceiling layout, where the LED strip will sit, the space the lighting components need and access for maintenance. Measure the lengths and plan the cuts, then choose the packing option shown on the product page.
Coffered ceiling planning
What are coffered ceilings?
Coffered ceilings are decorative ceiling systems consisting of recessed panels framed by beams or mouldings. They create architectural depth, visual interest, and a premium appearance.
What is a waffle ceiling?
A waffle ceiling is a type of coffered ceiling featuring a symmetrical grid pattern of recessed panels.
What is the difference between a coffered ceiling and a waffle ceiling?
A waffle ceiling typically has a uniform grid, while other coffered ceilings can use different beam and panel patterns.
What ceiling height is required for coffered ceilings?
There is no single minimum ceiling height listed in the coffered catalogue. Compare the chosen profile depth with your room height and layout. Ask how much height will remain below the beams before ordering.
Can coffered ceilings be installed on 8-foot ceilings?
In an 8-foot room, check how much ceiling height will remain below the chosen beams. Send the measured ceiling height, room dimensions and proposed grid to sales or your installer for advice.
Can coffered ceilings include lighting?
Plan the lighting together with the coffered grid. Confirm the chosen profile, light positions, space around the components, wiring route and maintenance access with the installer and lighting supplier. Support light fixtures separately; do not use decorative foam profiles to carry building or fixture loads.
Can coffered ceilings work with LED light coves?
Cove lighting may be planned with a coffered layout. Ask for drawings showing how the chosen profiles and LED strip will fit together, how the lighting will be mounted, the space it needs and access for maintenance before choosing the combination.
What are decorative ceiling beams?
Decorative ceiling beams are architectural elements used to add depth, character and visual structure to ceilings.
Are decorative beams structural?
These profiles are decorative trim. Use separate, suitably designed supports for building loads or lighting fixtures; the catalogue and technical guide do not give the profiles a structural load rating.
How do I choose the right coffered ceiling?
Measure the room and ceiling height, sketch the beam grid and mark lighting and other ceiling features. Compare the catalogue profile dimensions with the proposed layout. Send the profile codes, quantities, measurements and delivery postal code to sales. Confirm how the profiles will attach to the ceiling and the installation details before ordering.
