The manufacturing process becomes easier through renderings like these. This one is showing 3 dimensional preformed curved translucent panels laid in a basket weave pattern in a conventional flat 9/16” grid. Modular sized panels allow for renovation

without reconfiguration of existing grid.

Commercial Interior Environments with Curves Create Drama and Excitement

• Add Depth and Interest to an Interiors “Fifth” Plane

• New Opportunities in Lighting and Signage

• Guide Pedestrian Traffic

Design Professionals discovered the possibilities associated with ceilings in the late 70’s and the desire to add excitement and movement to the ceiling plane continues to grow. Buildings like the Guggenheim Museum New York, The Los Angeles Pacific Design Center, and Bilbao Spain all helped strengthen the foundation for Curves. Whether your adding lighting or signage, guiding pedestrian traffic or just adding depth and interest to a room. All rooms can be enhanced while incorporating curves.

The 5 Standard Types of Curved Ceilings

1.Perimeter trim – Which is typically vertical, available in multiple heights and color options 180/360 etc.

2.Metal accent systems - Examples of that would be a Razor Edge or paired suspension trims.

3.Curved metal -Available in one, and two directional systems. Also in Concealed torsion spring systems.

4.Drywall suspension can have Undulating Edges, Valleys, Vaults, and Domes

1.Luminous wave options for flat suspension with wave panels, and

wave suspension with conforming luminous or opaque infill panels.

Curved Perimeter Trim With Open Cell Grid

This is an example of an Open Cell Grid with Cloud curved perimeter trim. All the components are painted 360 degrees.

No Visible Suspension /Computer Assisted Perforation Lay-Out

Here is a parallel metal sculpture with No Visible Suspension “grid-less” feature system. The aluminum panels are individually fabricated and interconnect to form a continuous

uninterrupted plane. Notice the perforation pattern follows the design.

Wave Ceiling With Two Directional Suspension And Custom Lighting

McCarran Airport United Terminal, Las Vegas, NV used a 2 directional grid system with 2 X 2 perforated metal panels and Neon Sculpted lights to help guide pedestrian traffic leading to departure and arrival gates.

This system uses a series of preformed valleys and vault grid along with metal infill panels.

Undulating Luminous Ceiling

Undulating Luminous Ceiling with preformed translucent panels on a pre-engineered grid system.

Custom Wave Ceilings / Conceptual Type

• Various Types Of Materials – Metal, Wood, Gypsum, High Tech Plastics are all possible

• Types Of Access – Point access can be upward or downward

• Finish and Shape – Metal, Paint, Wood Grain, Metallic Paint, Polished and

Custom Painted in various shapes • Special Function

– Custom Lighting, Corporate Logos, Special Needs such as aesthetics or color for pedestrian direction or security

An Example Of A Custom Radius And Custom Trim

Custom / One directional Metal System with custom closure and custom edge trim

Curved Ceilings Can Perform

• Acoustical Performance Can Be Provided – Perforated metal panels can have an acceptable NRC of .65

with an absorbent fabric backer or .90 with a poly-bagged glass fiber insulation.

• Many Lighting Options

– Down lights, translucent infill panels, track lighting, soffit lighting, cove lighting, and even neon

• Light Reflectance Can Be Addressed

Curved Ceilings Can Perform

• Metal Protection: – Hot Dipped Galvanized or Aluminum Metal Panels both Provide Long

term Sustainability. Where Electro-Galvanized Metals are not acceptable for Sustainability. Interior Grid Market has changed from Electro-Galvanized to Hot Dipped Galvanized due to Red Rusting

• Sustainable / Recycled Content Are Important Today – Typical Average of Recycled Content: Aluminum = 90%; Steel = 25%;

Gypsum = 95-1% depending on material source. – Aluminum and Steel can be recycled from demolition, gypsum board

cannot.

Manufactured Perimeter Trim

• Curved & Straight Edges In Steel Or Aluminum

• Different Profile Heights – Ranging from 2”, 4”, 6”, 8” , 10” or 12”

• Vertical And Horizontal Capabilities

• Painted, Polished And Wood Grain

• Paired Perimeter Systems

Aluminum and Steel Perimeter Trim

Aluminum Perimeter Trim Steel Perimeter Trim

An example of grid attachment on both Aluminum and Steel Perimeter Trim through use of attachment clips. The difference in these two systems will be profile heights, minimum

radius, finishes, and ease of grid attachment through clips.

Perimeter Trim Creating Islands

Example of a large space being improved by the used of “islands” formed with Straight Perimeter trim. Straight systems are made from standard components which improve availability.

Curved Perimeter Trim Creating a Layered Ceiling and Soffit

Curved perimeter trim used to create “layered ceilings” that can

be used to conceal lighting or could serve for supply or return

air. There is also an opportunity to improve acoustics through this

type of layering.

Curved Perimeter Trim Creating a Layered Ceiling and Soffit

Another example of Curved Perimeter Trim used to create a undulating curved soffit edge

and return air through layered ceiling. Good contrast between white and black.

Islands and Voids

Here we can see how straight and curved trim can be used to compliment each other. The

larger shape is referred to as an island while the empty circle is a void.

Horizontal Edge Trim

Here is a example of a horizontal edge trim providing a wide low profile edge. It “frames” the island with a look that has a razor edge and is sometimes thought to be more contemporary. Can

only be used on square and rectangular clouds requiring inside and outside corners. Some Manufacturers provide premade corners to eliminate gapping at field mitered corners.

Wood Grain Options

Here the trim system is finished in a Wood grain finish. This example shows a linear plank pan in 2’ X 2’ and 1’ X 5’ panels. The wood grain trim complements the design. Coordinating trim

could also be supplied.

Paired Perimeter Options

Paired Perimeter Trim left empty, integrated with light track. Possible options could be to include neon in the reveal, use light rope or hang signage.

Manufactured Perimeter Trim

• Clean, Crisp Edges

• Curved Form Capabilities – Minimum Radius 18”-24”

• Made to Order- Arrives Onsite Pre-Engineered • Strong, Durable and Long-Lasting Steel or Aluminum Trim

Curved Main Tee’s are used as primary spokes on a radial arm Basis of Dome framework

Manufactured Components

Here is a very large Dome. Notice the main

tee placement (or primary spokes) and the

connecting cross tees. In this instance gypsum panels are being used. On smaller domes with

tighter radius it might be more advisable to stay

with plaster.

Special Acoustic and Lighting Solutions

In this DWSS example Special Acoustics and

Lighting were needed. The valley application was

designed to provide optimum acoustics. While the design

was selected for performance, economy, and ease of installation, it still provides a high level of

aesthetic appeal.
