WOODWORKS® Torsion SpringIns ta l la t ion Ins t ruc t ions

1. General

1.1 Product Description

WoodWorks Torsion Spring ceilings consist of perforated and unperforated veneered panels that are downward accessible, and are designed to be installed on an Armstrong Heavy-duty Prelude® XL® 15/16" wide T-Bar suspension system with field attached hardware to panels. All panels can be removed and reinstalled for access to the plenum. Panels are supported from the suspension system by metal brackets and springs that are screw-attached through predrilled holes.

Custom panel sizes are available in a maximum size of 16 sq. ft.

1.2 Surface Finish

All wood panels are constructed of wood chips factory bonded together between two layers of wood veneer finish. All exposed edges are banded with the same finish as the face.

1.3 Storage and Handling

Ceiling components should be stored in a dry interior location and shall remain in cartons or crates prior to installation to avoid damage. The protectors between panels should not be removed until installation. Proper care must be taken when handling to avoid damage and soiling. Do not store in unconditioned spaces with humidity greater than 55% or lower than 25% RH and temperatures lower than 50°F or greater than 86°F. Panels must not be exposed to extreme temperatures, for example, close to a heating source or near a window where there is direct sunlight.

1.4 Site Conditions

WoodWorks ceiling panels and veneer-wrapped trim should be permitted to reach room temperature and have stabilized moisture content for a minimum of 72 hours before installation. (Remove plastic wrap to allow panels to acclimatize.) They should not, however, be installed in spaces where the temperature or humidity conditions vary greatly from the temperatures and conditions that will be normal in the occupied space.

1.4.1 Temperature and Humidity During Installation

WoodWorks® ceiling panels are interior finish products that are designed for installation to be carried out in temperature conditions between 50°F (10°C) and 86°F (30°C), in spaces where the building is enclosed and HVAC systems are

functioning and will be in continuous operation. Relative humidity shall not fall below 25% or exceed 55%. There shall be proper ventilation of the plenum in high moisture areas.

All plastering, concrete, terrazzo, or any other wet work shall be completely dry. All windows and doors shall be in place. The heating, ventilation, and air-conditioning system should be installed and operable where necessary to maintain proper temperature before, during, and after installation of the WoodWorks panels.

In addition, during construction a humidity meter should be located at the height of the installed ceiling. This will measure humidity and temperature before and during installation to ensure the job site meets industry standard conditions per Armstrong warranty requirements.

1.4.2 Installation Considerations

WoodWorks Torsion Spring panels hang below the suspension system to which they are attached. The face of the installed panels will be 3/4" below the face of the suspension system. Gaskets are optional.

In the event of any conflict between the record set shop drawings and the installation instructions, the record set drawings take precedent.

Use of large wood panels may result in deflection up to 1/8" and alignment inconsistency due to size and ambient conditions. Do not mix different panel sizes with slotted perforations. Perforation border will not align.

A minimum of 4 inches above the suspension system is required for this installation.

not recommended for sloped ceiling installations.

2.1 General

The suspension system shall be standard 15/16" exposed tee grid. The installation shall, in all cases, conform to the requirements of the International Building Code and its referenced standards. Because these panels weigh in excess of 2.5 lbs/SF, the ceilings shall be installed with the following additional requirements:

• Heavy-duty rated 15/16" wide T-Bar suspension system

• Stabilizer bars are required on all perimeter edges unless some other means is provided to prevent spreading (such as fixed mechanical attachment to the wall, fixed mechanical attachment to Axiom® trim, etc.)

• Walls or soffits that serve to support a panel edge must be braced to structure so as not to allow movement greater than 1/8" when subjected to design lateral force loads. When such bracing is not practical or is not effective, additional mechanically connected suspension system components shall be provided to capture all edges of every panel. Axiom Perimeter Trim connected to the suspension system with AXTBC clips will also meet this requirement.

• The suspension system must be square

• Hanger wires shall be installed not more than 48" on center along the length of the main beams

• The suspension system must be leveled to within 1/4" in 10' and must be square to within 1/16" in 2'

The requirements listed here represent the manufacturer’s minimum acceptable installation recommendations, and may be subject to additional requirements established by the local authority having jurisdiction.

2.2 load Capacity

WoodWorks® panels weigh 2.75 lbs/SF. Therefore, heavy-duty main beams are required by building code. Main beams must be capable of carrying the weight of the panels plus any additional ceiling components that are not independently supported from the building structure.

2.3 Suspension System Installation

For your required suspension system layout, refer to your custom reflective ceiling plan.

2.3.1 Wall Molding

A 2" wall angle (item SWA9820HRC) should be used for this installation.

NOTE: Perimeter wires must be attached to the terminal ends of each piece of suspension system at least 4" but not greater than 8" from the wall. These wires must be plumb within 1 in 6 (10° angle).

2.3.2 Hanging Points

Before setting hanging points, review the record set of drawings for saddle clip locations as these may interfere with hanger wires. Before tying off any hanger wire to the suspension system, place saddle clips along the main beams per the custom plan. This will eliminate re-hanging wires that are found to interfere with saddle placement.

2.3.3 Main Beams

On center main beam spacing is determined by the width of the panel. Panels over 30" will require additional supports. Please refer to your custom reflected ceiling plan drawing for exact positioning. Border panels have a unique main beam spacing to allow for site condition modifications at the perimeters. A typical 1" reveal is recommended around the perimeter of the system. Cut the main beam length to position a route hole between each panel. Custom main beams may be required to accomplish this task.

Install the Top Lock Main Beam Splice (TLMBS) onto each main beam coupling to secure the connection using four #8 truss head sharp point screws. The Top Lock Main Beam Splice is required at every main beam splice location in the field of installation.

NOTE: Be sure to insert the screw from the larger (pilot) hole into the smaller hole on the other side of the clip.

2.3.4 Cross Tees

For cross tee location, refer to your reflected ceiling plan. All cross tee connections must be reinforced with a Grip Clip 3-way bracket (GC3W).

2.3.5 Perimeter attachment

Secure the ends of the suspension system to the wall with the Wall Anchor HD (item BP7100). At the two adjacent attached walls, insert one screw through the slot and one screw through a pre-drilled hole (as shown in detail below). At the two adjacent unattached walls, insert one screw through the center of the slot.

3.1 attach Brackets and Springs

Insert a spring into each bracket, then attach a mounting bracket at each set of factory drilled pilot holes on each panel. Three screws (item 91070A244) are required in each Mounting Bracket. Rotate the spring so the spring stands in a vertical position.

3.2 Cutting the Panel

Cut the panel using standard wood working tools and, where possible, a straight edge. A table saw is recommended for straight cuts and a band saw for curved cuts. In general, these practices will be typical of those employed in finish carpentry.

CaUTIOn! WOOD DUST. Sawing, sanding, and machining wood products can produce dust. Airborne wood dust can cause respiratory, eye, and skin irritation. The International Agency for Research on Cancer (IARC) has classified wood dust as a nasal carcinogen in humans.

Precautionary measures: Avoid inhalation of dust. If power tools are used, they should be equipped with a dust collector. If high dust levels are encountered, use an appropriate NIOSH-designed dust mask. Avoid dust contact with eyes and skin.

First aid Measure in case of irritation:

Flush eyes or skin with water for at least 15 minutes.

3.2.1 Treating exposed edges

Cut panel edges that are exposed to view will have to be treated to look like factory edges. Pre-finished peel and stick edge banding is available for this purpose. Cut edge must be clean and smooth before applying edge banding. Peel off the release paper and apply the edge banding using finger pressure or a small trim roller. Trim excess material with a sharp knife blade or with the edge trimmer available for order through Armstrong. Edge banding and trimming tools are ordered directly from Armstrong through the Customer Focus Center.

3.3 Panel Installation

Hold the panel in the vertical position and align the springs on one side with the corresponding saddles on the suspension system. Compress the springs and insert them into the corresponding slots. Swing the panel up into the horizontal position and engage the remaining springs into the saddles. When all springs are engaged in saddles, gently press the panel up into place with the palm of the hand. The springs will spread apart in the slots of the suspension system and seat the panel into place.

NOTE: If misalignment of the panels is noted, ensure proper alignment of the springs inside of the saddles to correct any visual issues.

4 . Panel reMOval

Panels can be removed from the system using the access tool at the panel removal pocket. WoodWorks® Torsion Spring border panels will always move away from the wall.

NOTE: For WoodWorks Torsion Spring, the swing down feature on the panels is only intended to aid with installation and removal. Due to the panel weight, the product is not designed to be left hanging in the swing down position and should always be removed from the space for access.

5 . SeISMIC reSTraInT

WoodWorks Torsion Spring has been engineered for application in seismic areas. No additional requirements needed as they are detailed in other sections of these instructions. Lateral force bracing is required for appropriate ground motion for the specific job location.

6. CleanInG reCOMMenDaTIOnS

Use a clean, dry, soft, white cloth to wipe off any dirt or greasy fingerprints. If this does not clean the panel, use a damp, clean, soft, white cloth or sponge with a mild detergent to wipe the panel.
