FAQ
How much to add for a filler piece of duct
When adding a filler piece to shorten the duct to a certain length or filling a piece to keep the duct at a certain length, add an inch for each lap at the s-cleat. Typically this is two inches for lapping over s-cleats. Just keep the thought in your mind to add an inch. If needed, draw a diagram on the floor to help reference the needed length.
How to make a hole in duct
Duct is usually made of 28-30 gauge metal in residential applications and can be from 16-26 gauge in commercial applications. For industrial applications, it can be even thicker. The thicker the metal, the harder it is to make a hole. If the hole is for a cutout, there is no need to be careful as long as the area taken out is discarded. Use the back of a hammer (a masonry hammer or roofing hammer are the best for puncturing duct). If care is to be taken, a screw hole can be put in the duct on a marked line and the cut can go from that point both ways.
Does hanging duct take two people
Hanging duct does not take two people. It is much easier if two people are used: one to stabilize the duct and one to install the drives and attach to the hanging supports.
Best ladder position for overhead work
The ladder should be placed where one person can easily install the drives and the other can stabilize the duct in the air.
What is the lap of a drive
The lap of a drive is one inch.
What should the lip of a duct be over a curb
The duct should lip over the roof curb at least one inch. It also needs to be secured with screws so it does not fall under its own weight.
Does a curb have to sit level
Every effort should be made to ensure that a curb is level in three directions: horizontally two ways and vertically. Additionally, the gap between the roof and the bottom of the curb should be shimmed so the curb does not bow under the weight of the mechanical unit.
Why do duct seams need to be sealed
The seams of duct are sealed to keep air from escaping as it is pushed by the furnace through the duct. The fewer holes in the duct, including at duct connections, the more efficiently the air will flow. This means reduced energy costs for the end user and less maintenance on the system over time.
