Atmosphere control in steel buildings is a major design issue, since comfort is always a priority. Heating, ventilation and air conditioning or, more commonly, HVAC, systems are mainly concerned with temperature regulation, airflow control, and other factors concerning the general comfort of the building occupants.

Steel Building Ridge Vents Designed to Allow Free Airflow

In addition to comfort, HVAC systems are also essential for keeping the building occupants on top form. Molds, bacteria, and other harmful organisms that harm not only humans but also certain objects stored within the structure. Such harmful organisms thrive in moist, unclean environments and contribute a lot to increasing the chances of viruses and other illnesses getting acquired by the building inhabitants. Apart from health reasons, having a poor HVAC system can also damage certain equipment. If not well maintained, factors such as temperature and airflow can hasten or aggravate oxidation, in other words, rusting. Consequently, not only performance, but likewise, service life of equipment decline. This need for a superior HVAC system is especially true for museums and archives, where preservation is top priority. Historic artifacts are easily affected by changes in the environment, particularly shifts in temperature.

Proper ventilation is extremely important in steel buildings, since steel, being a metal, is highly vulnerable to condensation and heat transfer. With steel buildings, accessories are often used in place of HVAC systems. A ridge vent, one of the most common accessories, is specifically effective when it comes to reducing condensation.

Ridge vents, found at the peak of the steel building’s roof, are often used with louvers, gravity vents, and turbine vents. Pairing devices contributes to acquiring adequate ventilation throughout the entire steel building. Size is also essential to achieving this well-ventilated effect for the structure. Most suppliers believe that every 10’ ridge vent will be sufficient to regulate airflow for an area of 2400 square feet, given no obstructions. This has actually become more of a "rule of thumb" when setting up ridge vents. Hence, the size of the ridge vent should be well calculated before it is installed. Several other factors, just like the number of people who will supposedly occupy the area, must also be considered. Else, a poor choice could lead to future problems and incur more costs.

The growing global concern about energy efficiency has put ridge vents in the spotlight. The right design and installation of ridge vents determines the performance of the ventilation system. Achieving proper ventilation means less work for, say, air conditioning systems, less energy consumption, less resources used up.

Nowadays, ridge vents come in ready-to-install packages, making set up quick and easy. Ridge vents are commonly available in various sizes, ranging from 10’ to 0" lengths and 1" to 12" throats. This makes it very customisable for the building’s requirements. One practical tip about installing ridge vents: it should be mounted no closer than 5’ to 0" to the end wall steel line. This grants room for natural airflow and gives just the right amount of room to flash the steel building.
