ACOUSTA-WAL® SPECIFICATIONS
RAW BLOCK ACOUSTA-WAL® Sound Absorbing Masonry Unit Specifications
Part 1-General
SUBMITTAL
Submit product literature, certifications, test
reports, and full size sample(s).
QUALITY ASSURANCE
All sound-absorbing masonry units shall be ACOUSTA-WAL® units produced with special mold parts available from Trenwyth Industries, Emigsville (York), PA. Production shall be monitored so that the top of the units shall be completely closed and edges of slots and ends of blocks shall be straight and clean. Type IV units shall have fillers as supplied by Trenwyth Industries, inserted in the cavities at the block plant. Type IV fillers shall be fiberglass fillers laminated to metal septa. All filler material shall be cut accurately to size and installed as recommended for the type of ACOUSTA-WAL® units specified.
Fire Resistance: Define hourly ratings required as 1, 2, 3, or 4 hours.
Field Constructed Mock-ups: Construct a sample panel, no less than 4' x 4', of units of each color and size to be used in the project.
DELIVERY, STORAGE, AND HANDLING
ACOUSTA-WAL® units shall be delivered to the jobsite on covered banded pallets with cardboard between layers. Store pallets in single-stacks on level ground and cover with waterproof covering (e.g., tarpaulins) to protect the blocks from inclement weather. Handle blocks carefully to avoid breakage and damage to the finished surfaces.
PROJECT/SITE CONDITIONS
Protection of Work: Cover walls each day after installation to keep open walls
protected and dry.
Trenwyth requires ordering a full size unit to illustrate color and texture for approval. Trenwyth Industries requires a jobsite sample panel be installed at the jobsite prior to installation of any Trenwyth products. This panel will represent both the quality of the product and the workmanship to be expected for the project. The panel must be approved by either the owner or architect for the project. Trenwyth will provide 4" units for a sample panel 4' by 4' and no cost for the material (not including freight to site).

SIZES AND SHAPES
ACOUSTA-WAL® units shall be 8" x 16" nominal face size. They shall be:
. 4" or 6" thickness Type I
. 8", 10", or 12" thickness Type IRF
. 4" or 6" thickness Type IV
. 8", 10", or 12" thickness Type IVRF
Part 3-Execution
INSTALLATION
ACOUSTA-WAL® blocks shall be consistent with the best concrete masonry practices. Only quality units shall be installed; all defective units shall be rejected. No broken, chipped or cracked units shall be used. ACOUSTA-WAL® blocks shall be laid in running bond or stack bond as specified with the closed tops up. They shall be laid in a full horizontal bed of mortar. The slots shall face toward the room or area where sound absorption is required as shown on the plans. Slots shall be kept free of mortar and debris and the exposed mortar at the bottom of each slot shall be neatly tooled. NO RAKE JOINTS
FLASHING OF MASONRY WORK
Install flashing at locations shown in the plans and in strict accordance with the details
and the best masonry flashing practices.
INSPECTION
The ACOUSTA-WAL® blocks shall be free from chips, cracks, crazes or any other imperfection that would detract from the overall appearance of the finished wall when viewed from a distance of twenty (20) feet at right angles to the wall with normal lighting.
INSTALLATION RECOMMENDATIONS
The units should be laid in a full horizontal bed of the mortar. They should be laid with the closed tops up.
The slots should face toward the noise source (with the exception of partitioning a small office off from a large noisy plant area). Slots must be kept free of mortar. The exposed mortar at the bottom of each slot should be neatly tooled and all debris removed. NO RAKE JOINTS
Under no circumstances should the units be laid upside down, that is, with the closed tops down. First, it would be impossible to lay the units in a full horizontal bed of mortar if they are laid upside down, and second, excess mortar would fall into the slots giving an unsightly appearance. If the cavity volume were reduced by more than 5 to 10% due to mortar falling inside, the acoustical performance of the units would be altered.

MASONRY CLEANERS
Use masonry cleaners such as SURE-KLEAN®600 or VANA TROL®, carefully following manufacturer's instructions.
CAUTION! The following solvents must never be used as they may damage ASTRA-GLAZE-SW+/ACOUSTA-WAL block facings: paint remover, lacquer thinner, epoxy thinner, methylene chloride, acetone, muriatic acid.
PART 3 - EXECUTION
INSTALLATION
ASTRA-GLAZE-SW®+/ACOUSTA-WAL® units shall be installed by the general contractor or masonry contractor. ASTRA-GLAZE-SW®+/ACOUSTA-WAL® blocks shall be laid in running bond or stack bond as specified with the closed tops up. The slots shall face toward the room or area where sound absorption is required as shown on the plans. Units shall be laid in a full horizontal bed of mortar.
Cutting: Make all unit cuts, including those for bonding, holes, boxes, etc., with motor driven masonry saws, using either an abrasive or diamond blade. Size and place cut pieces appropriately to maintain consistency and bond.
WORKMANSHIP
Lay ASTRA-GLAZE-SW®+/ACOUSTA-WAL® units with the faces level, plumb, and true to a line strung horizontally at the glazed face. Units shall have uniform joint dimensions of 1/4" both horizontally and vertically. Tool joints neatly after they are finger-hard to make them straight and uniform. Slots shall be kept free of mortar and debris and the exposed mortar at the bottom of each slot shall be neatly tooled.NO RAKE JOINTS.
The laying of ASTRA-GLAZE-SW®+/ACOUSTA-WAL® blocks shall be consistent with the best concrete masonry practices. Only quality units shall be installed; all defective units shall be rejected.
FLASHING OF MASONRY WORK
Install flashing at locations shown in the plans and in strict accordance with the details and the best masonry flashing practices.
INSPECTION
The glazed facing shall be free from chips, cracks, crazes or any other imperfection that would detract from the overall appearance of the finished wall when viewed from a distance of five (5) feet at right angles to the wall with normal lighting.
CLEANING
Keep walls clean daily during installation using brushes or rags and a clean damp cloth. Harsh cleaning methods after walls have been erected may mar the surface of the blocks. Do not allow excess mortar lumps or smears to harden on the glazed surfaces. Remove green mortar with a dry cloth. Do not use steel wool, sandpaper, or other abrasives.DO NOT POWER WASH.
MAINTENANCE
ASTRA-GLAZE-SW®+/ACOUSTA-WAL® units, properly installed and cleaned, need virtually no maintenance other than routine cleaning with standard commercial grade cleaning agents such as PINESOL® or FANTASTIK. Graffiti, paint or dye may need special cleaning methods and products such as Trenwyth's Graffiti Wizard environmentally friendly cleaner. Contact manufacturer for specific cleaning recommendations.
INSTALLATION RECOMMENDATIONS
To insure good sound transmission loss performance:
. The unslotted side of ASTRA-GLAZE-SW®+/ACOUSTA-WAL® blocks must be painted or parged to seal the porosity of the aggregates.
. The units must be laid in a full horizontal bed of mortar.
. For best appearance, use stack bond construction when stack bond appearance is desired (as opposed to scored units in running bond).
