MISCELLANEOUS INFORMATION

1. To prevent galvanic action, isolate any aluminum trim surface(s) from surface of panel support steel using one of the following methods:

a) An approved sealant or sealant tape.

b) A non-absorbent gasket.

c) Duct tape or equivalent type tape.

d) Paint the incompatible metal with a coating of heavy bodied bituminous paint.

2. Gas bubbles on foam panels are an industry-wide, sporadic problem. If they occur on this project, they can easily be repaired by drilling

a 1/16" diameter by 1 3/4" deep hole near the bottom of the gas bubble in the exterior metal facing to allow the trapped gas to be

released. The repair is completed by applying a small amount of clear acrylic touch-up paint to the raw edge of the drill hole. Gas

bubbles should be repaired as soon as possible as they will continue to grow until corrected. Gas bubbles are not a cause for rejection

of the panel(s).

EXPOSURE TO HEAT OR FLAME

1. Although the urethane core panels are acceptable for use in non-combustible building assemblies in accordance with the International

Building Code (IBC) and have been exhaustively tested for fire resistivity based on their end use, they are not non-combustible in and

of themselves. They are not "fire rated" per ASTM E 119. Therefore, they shall not be exposed to extremely high temperatures or direct

flame at any time. Simply stated, do not use a welding torch on or near insulated panels any more than you would on a wooden building

assembly. Refer to panel test data information under "fire" for detailed information on ignition, heat of combustion, and surface burning.

CLEANING PANELS

1. After installation, surfaces must be cleaned to remove any metal chips to prevent any possible oxidation. A wet, soft cloth is recommended.

MAINTENANCE

1. Proper installation and maintenance are extremely important to obtain the best performance and appearance from the insulated panels.

2. Dirt, oil, grease, fingerprints or any other kind of contaminant must be completely removed when the installation is finished to maximize

coating(s) performance.

3. The building will require periodic maintenance according to site conditions (U.V. exposure, dirt, smoke, corrosive atmosphere, etc). If

further assistance is required, please consult Metal Sales Technical Services department.

4. To remove superficial oxidation and tough stains, it is recommended to use a regular household cleaner followed by a thorough rinsing.

Wire brushes and/or abrasive material will damage the painted coating and should never be used.

5. If "touch-up" paint is required, contact Metal Sales to obtain a paint chip for color-matching.

6. Since metal-faced insulated panels are a modular system, they require joint and intersecting caulking to minimize potential leaks in the

building envelope. The flexible sealant materials typically used are gun-grade or ribbon-type and either butyl, silicone, or urethane-

based, depending on the specific application. It is essential to inspect critical areas such as roof endlaps, ridges, or any trim used to

complete the building envelope every 24 months after the first 60 months in-place. Over time, sealants will shrink, crack, and lose

adhesion when subjected to heat and cold, freeze / thaw, expanding / contracting metal, moisture, and chemical contaminants. Sealants

can be removed and replaced where practical or areas can be face-sealed from the interior. For specific recommendations of sealant

type(s) and / or application(s), contact your Metal Sales representative.
