BUILDING ISOLATION
BUILDING ISOLATION 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. Ground vibration may be generated by above ground or under ground passenger or freight trains,…
ARCHITECTURAL ENGINEERING
ARCHITECTURAL ENGINEERING We have been floating floors, resiliently suspending ceilings and isolating walls for close to 45 years. The need for this acoustical reinforcement has been well established in textbooks, sales literature and acoustical engineering recommendations. Therefore, we thought it would be helpful to offer a handbook of specific methods and suggested specifications rather than…
SEISMIC ENGINEERING
Seismic Engineering Our company started calling on West Coast engineering firms as early as 1960. We opened our L.A. sales and applications office in 1965 when it became important to provide local service to the most seismically active parts of the country in California, Oregon, Washington and Alaska as well as Vancouver, Canada. Very few…
HVAC ENGINEERING
HVAC ENGINEERING In 1962 we introduced our first “HVAC ENGINEERING SPECIFICATION.” While the 1962 approach was very well received and filled a void, it was made up of many individual specifications rather than presented in an organized format.It had no meaningful minimum static deflection guide and engineers found it hard to work with. In 1965…
