Decoustics - Quadrillo

DESCRIPTION
Quadrillo is a natural wood veneer finish. Acoustical absorption is achieved by a unique patented perforation technology in combination with Decoustics high performance acoustical cores.
Panel edge conditions are available plain (unfinished), edge banded 3 mm (.118 inches) or fully framed with matching veneer finish. Panels can be mounted into existing millwork frames, or splined to create a monolithic appearance. Face frames of almost any width and profile can be created with a variety of corner details.  There are currently two design profiles available - one with the grooves (5 mm) o.c. and the other with ribs (10 mm) o.c. When used as a monolithic panel system, kerfed edges with splines are used to level the panel faces. The reveal between the panels is 3 mm which simulates the v-groove on a panel having ribs at 5 mm centers. Installed carefully, surfaces can appear monolithic, however panel joints are not invisible due to the change in geometry of the panel edges.  Quadrillo is available in nine different natural wood veneers. Matching and custom veneers can also be accommodated.

LIMITATIONS
Quadrillo does not carry a "Class A" (ASTM-E84) composite designation, as few wood products do in interior architecture. Quadrillo is manufactured in two types:

1. FIRE RETARDENT: Acoustic core, framing and lacquer finish are Class A components. Refer to AWI handbook for more detailed data. Note: Local codes fluctuate widely; check with authorities prior to use.
Close attention must be paid to acclimatization during installation. The site must be stabilized to final temperature and humidity controlled conditions prior to commencement of work as is typically practised in the interior wood working industry.

2. STANDARD: Not all applications require a Class "A" fire classification. Quadrillo is available with non-fire retardant components at significantly lower costs.

DESIGN CONSIDERATIONS
MAXIMUM PANEL SIZE: 4'-0" x 10'-0" (1220 mm x 3050 mm). Note: large panels are subject to significant movement when subjected to climactic changes. This can be overcome by using smaller panels. Also, a typical QPS-25 panel weighs approximately 3.50 lbs. per sq. ft. (17.1 kg/m2) and therefore a large 4'-0" x 10'-0" panel would weigh over 100 lbs. (45 kg) which may be impractical. Decoustics typically recommends a more manageable size of 12 to 20 sq. ft. (1.1 to 1.9 m2) per panel.

VENEER SPECIFICAION: Quadrillo veneer lay up is produced as slip matched, quarter sliced as a standard. Other veneer cuts and lay up options are available by request at additional cost. Veneer sequencing is not a standard practice but can be specified as required. Curved Panels: See Maximum Panel Size above. Minimum radius for outside curve is approximately 16" (400 mm) and inside curve is 24" (600 mm); tight radius panels may be non-acoustical.

FINISHING: Quadrillo is available prefinished in natural lacquer or unfinished for post application by others. DECOUSTICS can provide custom lacquer toning, tinting and sheen to match other wood finishes. An acceptable representation should be supplied and a prototypical sample produced for design acceptance and sign off.
Cautionary Note: Quadrillo panels are frequently used in conjunction with solid, millwork veneer panels. It is highly recommended that a single finishing source produce both Quadrillo and Flat panels where toning and sheen are matched.
In these instances, DECOUSTICS can provide unfinished panels.
RECOMMENDED USES
Ceilings and walls.  Available with Decoustics Ceilencio Custom ceiling suspension system (downward access) and other direct mount and suspended ceiling systems. Note: the use of curved panels on Ceilencio may be limited. Consult Decoustics for use criteria. The grooved Quadrillo facer is not available by itself as a finish for non-acoustical applications. The facer is designed to be used in a laminated or "sandwich" construction. Consult Decoustics for any non-acoustical application.

FEATURES AND ADVANTAGES
Available in both standard and custom sizes.
Impressive sound control properties. Panels can be manufactured with grooves running horizontally or vertically. The grain and groove must be in the same direction. Consult Decoustics for maximum sizes.
Quadrillo panels are available with a clear, natural lacquer or toned or tinted to match other finishes. "See Finishing" under Design Considerations. Quadrillo is
also available in a painted version to match any color.
Although the percentage of open area of Quadrillo is only 3.2%, the patented v-grooves create a four sided "funnel" effect that allows sound to arrive at a variety of angles thereby focusing the transfer of energy over a broader surface area of absorption material.

ADDITIONAL DATA
Ordering: As with most millwork process, Quadrillo is a longer lead time item and should generally be dealt with early in a project. Allow eight to ten weeks manufacturing time after all dimensions, veneer, samples and drawing approvals are provided. Custom matched or sequenced veneers may take longer and should be reviewed with DECOUSTICS in advance of ordering. Samples: It is important that samples be approved based on the finished product and not just a sample of veneer only. Held close in hand, a dark veneer with a lighter groove could be quite evident but when viewed at a moderate distance, the color will appear as one. Panel Weight: Depending upon thickness and whether or not framed, generally a QPS-25 panel having an overall thickness of 1-3/8" (35 mm) weighs an average of 3.5 lbs. per sq. ft. (17.1 kg/m2). A QPS-50 panel thickness of 2-3/8" (60 mm) weighs an average of 4.5 lbs. per sq. ft. (22 kg/m2). Solid wood border frames can add significantly to these weights.
