300C – Linear Plank Ceilings / Hunter Douglas Contract


have the power to increase design potential for architects by defining, maximizing and even dramatizing interior space. For decades, Hunter Douglas has engineered its ceiling systems for design versatility, as well as ease-of-installation, with industry-leading sizes, options, and colors, as well as an exclusive universal carrier system that lets architects mix and match widths and panel depths.

One of the most versatile, consistent ceilings in the industry, 300C metal panels, creates a distinct, smooth look for any interior. These panels offer a subtle, long span design featuring a butt-joint, “bevel edge” that moderates panel-to-panel connections for an orderly, finished design. Hunter Douglas experience in designing and manufacturing ceilings is shown in every detail of their products.

Perforation Patterns / Acoustics

Sound Absorption

In order to improve interior sound control, the metal ceiling panels can be perforated and also fitted with non-woven acoustic tissue or an acoustical pad. Two different perforations are available: The diameter of the holes in mini perforated panels is .059″ (1.5mm) in a .118″ (3mm) triangular pattern; the apertures represent 23% of the perforated area. The diameter of the holes in standard perforated panels is .078″ (2mm) in a .196″ (5mm) triangular pattern; the apertures represent approx. 15% of the perforated area. Fiberglass encapsulated acoustic pads can be used to achieve acoustic absorption. Also non-woven acoustic textile is available which is adhered to inside the panels automatically during production.

#160 23% Non-Woven Acoustic 0.70
#160 23% 1”-1.5 pcf Polywrapped Fiberglass and Non-Woven Acoustic


*Acoustical Tests performed in accordance with ASTM C423 and ASTM E795, in a type E400 mounting.

Trim Options: EdgeLine Trim Systems

Designed for a wide range of suspended ceiling systems, EdgeLine ceiling trim adds a finished look to both commercial ceilings and architectural ceilings. These aluminum ceiling trims are available in Blade and a wide range of Channel sizes and were created to integrate with all types of ceiling panels, including Luxalon metal ceilings, Techstyle acoustical ceilings, and many other systems. Their smooth finish and stable construction ensure outstanding durability to match their good looks.

Recycled Content

Hunter Douglas aluminum ceilings are manufactured from material with 70% recycled content

-40% is post-consumer
-30% is pre-consumer

    i hope in this section you will be able to present clearly materials to architect focusing on what matters more during design phase (standard size, finishes, limits, cost, +,etc..)

  • Archlad

    It’s incredible how the type of ceilings to be used in a project can impact its overall look.

  • Rod Nuffert

    Not only impacts on its look, but acoustically it can make a BIG change. Many times architects don’t think too much on the ceiling they are using or just choose it for it “looks”, and that’s a big mistake. As everybody cares about “wall insulation” or “glass façades”, there should be a big thinking about interior materials, that can make a huge difference.

    Hope HD can make a good showcase of this, taking advantage of the great architectural community over here
