ARCHITECTURAL CEILING HANGERS |
Floating Floors remain the most effective way of reducing sound transmission and vibration from the floor above. However, there are many situations where a floating floor is impractical or not economically feasible, so an isolated ceiling becomes the practical choice.
There are two types of ceilings.There are the simple acoustical tile ceilings that surround the lighting fixtures, duct outlets, etc., and conceal unsightly ductwork, piping and electrical work. The acoustical tile reduces the reflected noise within the room, but does virtually nothing to reduce sound transmission from above. It does not prevent noise within the room traveling upward or over partition walls that are not floor to structural ceiling. |

SPRING, RUBBER and COMBINATION HANGERS |
Over fifty years ago, vibration control hangers were in their infancy and it was not uncommon to use isolation materials such as a block of cork with a hole drilled through the center, two or three layers of rubber and cork pads or felt within the hanger frame.These products all gave way to the lower frequency bonded steel strip rubber-in-shear elements and then to round rubber-in-shear designs which were lower incost and higher in capacity. |

Through the use of aircraft cable with swivel anchors, piping, ductwork and suspended equipment can be safely prevented from swinging out of control during earthquakes or when exposed to wind. |

WBI & WBD Thrust Restraints |
Fans Heads are cabinets containing a fan and motor and no accessories such as coils or filters. They can develop extremely high thrusts that are equal to the suction area multiplied by the negative head plus the positive pressur emultiplied by the discharge area. These forces act horizontally, opposite to the airflow and about halfway up the cabinet. Since fan heads are light and narrow they tend to shift and overturn with damage to the flexible connections or to the units themselves. |
