UNI-HOUSING Panel System Enclosures Used in Pressurized/Nonpressurized Applications McGill AirSilences UNI-HOUSING enclosures are designed to have low leakage, provide excellent thermal and acoustical control, and facilitate easy on-site assembly for both pressurized and nonpressurized applications indoors or outdoors. Applications include enclosures for built-up air handling systems, as well as outside intake air, supply-return air handling, and fan system plenums. Large rectangular duct systems can also be fabricated from UNI-HOUSING panels. Depending upon the application and size, McGill AirPressure can deliver finished units or subassemblies to the site.
UNI-HOUSING pressurized enclosures are assembled from McGill AirSilences Type SL (snap-lock) and Type TG (tongue-and-groove) panel systems, identical except for their panel joint designs. The TYPE SL panel offers quick assembly and is used in applications where disassembly is not a primary concern. The Type TG panel has a simple tongue-and-groove design that is recommended when future disassembly and re-erection of the enclosure may be required. All of the standard wall, door, roof, and floor panels are available with either snap-lock joint design or tongue-and-groove joint design. Both SL and TG panels are available in standard 4-inch thickness or optional 2-inch thickness, with other thicknesses available by special order. Standard panel widths are 24 inches and 36 inches with standard lengths up to 12 feet. Other widths and longer lengths are also available through special order. Both
types of panels have sandwich-type construction, with a solid galvanized
steel outer shell, acoustical/thermal insulating fill, and either a solid
or perforated inner liner of galvanized steel with a minimum G-60 zinc
coating. Many different material and gauge combinations of outer shell
and inner liner can be selected. The standard fill is 1.55 pcf fiberglass,
giving the standard 4-inch-thick panel an R17 value. The fill will not
settle or promote the growth of bacteria, mold, vermin, or insects. A
moisture barrier separating the insulation from the inner perforated metal
liner, can also be specified, as can optional joint insulation. All insulating
materials, inner and outer surfaces, and sealants used in UNI-HOUSING
pressurized enclosures meet the requirements of ANSI/NFPA 90A. UNI-HOUSING is a trademark of United McGill Corporation. |
