Plenum-rated data cable is derived from an old HVAC term referring to “plenum spaces”.  A plenum space is the division of a building that facilitates air circulation by providing pathways for heated/air-conditioned and return air-flows at a higher pressure than typical.

Simply put, plenum rated low-voltage data cabling has an extra fire retard applied to the shielding portion of the cable making it more resistant to heat and less likely to cause fires vs. non-plenum cable which does not have this extra layer of fire protection.

The choices Onsite Computer Services available for different cable products these days are very abundant. Everyday new options are being introduced into the electrical market. Whether it be from the parameters changing to the different variations, the choices are becoming more and more plentiful as time goes on. One option; however, which is usually the first thing a person takes into consideration when purchasing cable remains pretty constant. This is whether or not the cable to be used will need to be plenum rated or Non-Plenum rated.

There are two basic types of building construction as it regards the movement of heating, air conditioning and ventilation through office buildings. In these modern times, every business needs a reliable cabling system to handle their voice and data needs, and if you do not want any untoward delay in your operations due to a massive system failure then you should only get the services of reliable structured data cabling services. As the years pass, more and more technological innovations seem to pop out of the woodwork, and this is all the more reason why you should get a cabling system that can manage all of these new devices and infrastructures so your business can reap all of their benefits.

In newer construction and in most high-rise construction the architects save space and the cost of expensive sheet metal return air ducts by simply drawing the air back to the heating/air condition unit through the open spaces above the ceiling and between the walls.
