| 1. Are AIA/CSI learning units available for MgO board? |
|
| Attention AIA/CSI members: If you or your colleagues need to earn AIA/CSI Learning Units online, log on to www.architect-forum.com. Click the Continuing Education tab see "How to Combat Mod Improve Air Quality and Specify MgO Products". |

| 2. Do the boards need to be taped like the Gypsum boards? |
|
| DRAGONBOARD can easily be taped and spackled on its tapered edges. Finish just like common drywall. |

|
| 3. What types of applications can DRAGONBOARD be used for? |
|
| Applications include single-family homes, apartment complexes, commercial high-rise buildings, theaters, museums, schools, hospitals, retail, hotels, restaurants, nightclubs, airports, subway stations, tunnels, fire separations, etc. DRAGONBOARD is a U.S. patented, UL approved fire resistant, water resistant, high-impact construction panel that is well-suited for both interior and exterior sheathing applications. With its mold resistant, fire resistant and high impact properties, DRAGONBOARD should be used whenever there is a high value placed on a building’s contents and equipment or when health and safety concerns exist. |

| 4. How does DRAGONBOARD differ in weight compared to Gypsum boards? |
|
| DRAGONBOARD is a far denser material than Gypsum, thus making it highly impact-resistant. As such, DRAGONBOARD weighs about 20% more than drywall. However, in fireproof applications, you will need fewer sheets of DRAGONBOARD to achieve a 2 or 3 hour UL rated assembly. |

|
| 5. What types of fire protection does DRAGONBOARD offer? |
|
| DRAGONBOARD offers superior fire protection. It requires only a single layer, which expedites job completion, saving time and money. DRAGONBOARD is approved for 1-, 1 1/2-, 2-, 3- and 4-hour fire resistant wall systems, providing an unprecedented degree of safety and security. DRAGONBOARD has flame spread and smoke propagation ratings of 0 per ASTM E84. STC ratings of 53 on a 2-hour UL assembly and 54 on a 3-hour UL assembly are available. A Dade County hurricane qualified system is also available. DRAGONBOARD's New York City MEA number is 359-02-M. For 2- and 4-hour fire resistant wall assemblies, the MEA number is 85-05-M. ICC approval is pending. |

|
| 6. Is there any rating for a one-sided fire assembly? |
|
| There is no rating for that application as UL tests are not given for every contingency. Remember ASTM E 136 provides useful information relating to non-combustibility, albeit with no UL hour rating. |

|
| 7. How do you treat the holes for outlets, holes, for firewall assemblies? |
|
| Normal switches and outlets do not affect the rated wall with DRAGONBOARD or drywall. |
| Top |
|
| 8. Can you use DRAGONBOARD in a Parapet Wall? |
|
| This application is fine for DRAGONBOARD. If you need to “cap” the parapet, the top piece of DRAGONBOARD will sit on top of the assembly. A slight overlap is okay. The top of the assembly should not have the DRAGONBOARD placed inside the parapet and screwed from the sides, but rather it needs to be placed on top like a cap, and be fastened from the top. |

|
| 9. How does mold affect DRAGONBOARD |
|
| DRAGONBOARD is a non-nutrient to mold or fungus per ASTM G21 and does not support insect life. It provides superior moisture resistance in high-humidity areas and combats the growth of mold and mildew. |
| Top |
|
| 10. What is the Sound Transmission Loss Test (STC) Rating (acoustical – reduction) of DRAGONBOARD? |
|
| We did not test DRAGONBOARD panels for Sound Transmission Loss Test (STC). The rating would have been just a bit better than a comparable naked sheet of drywall – it achieves a 53 on a 2-hour wall system and a 54 on a 3-hour wall. |
