Architectural Information

	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… Download
	BUILDING ISOLATION DISCUSSION Noise and vibration isolators are used to prevent the downward transmission of vibration from a machine to a structure, the upward transfer from the structure to a sensitive machine or to isolate a complete building from ground vibration… Download
	ARCHITECTURAL ISOLATION DISCUSSION We have been floating floors, resiliently suspending ceilings and isolating walls for close to 45 years… Download
	NEOPRENE SOUND ISOLATION SYSTEM The noise isolation efficiency of mechanical or gypsum board walls and ceilings is seriously threatened when solid connections are made to noisy structural walls, ceilings or floors. Simple inexpensive neoprene isolators can break these sound paths when used as wall braces, ceiling hangers or floor supports… Download
	EAFM MOUNTS FOR FLOATING FLOORS In 1976, the acoustical community asked us to develop a floating floor mounting that would last as long as the building and provide response frequencies lower than two inch (50mm) thick fiberglass… Download
	EAFM MOUNTS FOR SOUND AND VIBRATION CONTROL Acoustical solutions are in the 6 – 8 Hz frequency range. However, these very same low stress isolators can be stacked with steel shim plates between to achieve lower frequencies for vibration isolation… Download

Seismic HVAC Isolation

	MASON INDUSTRIES SEISMIC RESTRAINT GUIDELINES These guidelines provide general seismic restraint requirements and details for suspended piping, ductwork and electrical systems. Prior to installation, the support and seismic restraint locations shall be verified by the engineer responsible for the design of the structure… Download
	A PICTORIAL STUDY OF SEISMIC DAMAGE On an early January morning in 1994, the Northridge area of Southern California was shaken by an earthquake that measured 6.6 on the Richter scale and lasted approximately 30 seconds. The repercussions are still being felt throughout the engineering community… Download
	SEISMIC SPECIFICATION APPLICATION DRAWINGS Seismic Applications are basically the same as Non Seismic but complicated by the need to keep equipment in place. Whenever we show our Z-1011 heavily cushioned snubbers, the input to the equipment will not exceed 4 G. All mountings, hanger-cables or snubbers are designed to resist the seismic force in any zone or specification… Download
	EXPLANATION & INSTRUCTIONS FOR THE USE OF COMPLETE SEISMIC HVAC ENGINEERING SPECIFICATIONS Introduction to Seismic Vibration Control Specifications for Office Buildings, Colleges, Hospitals, Theaters and similar structures… Download
	COMPLETE SEISMIC HVAC ENGINEERING SPECIFICATIONS All mechanical equipment, piping and ductwork as noted on the equipment schedule or in the specification shall be mounted on vibration isolators to prevent the transmission ofvibration and mechanically transmitted sound to the building structure… Download
	EFFECTS OF SEIMIC INPUTS ON RESILIENTLY MOUNTED MECHANICAL EQUIPMENT Earthquake control of resiliently mounted systems is an area of primary concern for acoustical and mechanical engineers… Download
