The installation instructions for many of the fans available today show a metal type box that has screws going through the box and into blocking above the box. This is not what is installed in most of the newer construction homes which use the labor saving nail-on products. As a general rule builders and contractors do not provide blocking above the ceiling box with a nail-on product as the added material & labor is not cost effective. The average nail-on plastic ceiling box is rated for only supporting a 35 pound static load. They are also not fan-rated. This requires that the ceiling box be replaced with a fan-rated box before the installation of a ceiling fan. Fan-rated boxes are capable of holding 70 pound loads and are rated for this application. This is easier said than done! The nail-on products do not lend themselves to be reinforced easily since labor savings have also been applied to the construction of homes themselves. In many circumstance the average home does not have an attic, only a narrow crawl space between the trusses is provided. This combined with blow-in insulation makes the location of the ceiling box difficult if not impossible when a fan is to be hung on an upper floor.
A Better Way. Following the trends used in the construction methods of today's homes has led to the development of a new and simple method to reinforce an existing ceiling box to that of a fan-rated box that is consumer friendly. Access is gained through the ceiling box itself with a small bracket being utilized in what is in most cases is wasted space within the ceiling box itself. Two fasteners are driven through the ceiling box and into the joist or truss with the bracket being firmly held in position. This bracket has been shown by independent testing by a leading product testing laboratory to allow the ceiling box to sustain very large dynamic loads.
Office presentation rooms too do not desire light to reflect from the walls on to the projection screen or wall thus, here too, the back ceiling comes in handy. Commercial kitchens like the restaurants or hotels must have black color ceilings so that soot from charcoal ovens on grills that is deposited on the roof mainly does not alter the look and feel of the kitchen. A lighter colored roof for a kitchen can be disastrous since maintaining and cleaning can be a big issue. Blackened ceilings help solve this issue.
