Ideas Duct work simply refers to ducts used for heating, air conditioning and ventilation you will find in all large buildings and some large homes. These ducts are also called H VAC (heating ventilation and air conditioning), are used to allow air passages throughout a structure by connecting rooms and floors to a central air pathway. The duct supplies air, returns air and exhausts air within the building. Proper air ventilation is not so important during the mild months when you can just open windows. But it becomes vital during cold months when we use indoor heating are during hot months when we need cooler air to create a pleasant atmosphere for work and living. To check on the availability of supplies contact hardware that specializes in duct-work H VAC, such as Audubon Plumbing Supply. You might also want to canvas for contractors to build your H VAC systems if your local supply stores cannot provide one for your or refer you to reputable contractors. Usually a contractor will have hardware where they regularly source their supplies, sometimes at a discounted member’s rate. Since H Vacs are supposed to function in order to maintain indoor air quality that is of healthy standards for those inside the building, it is best to find contractors who have done similar jobs in their previous jobs, and not to rely on general contractors or beginners.
.Ducts are also used to deliver thermal comfort in the warm months and having your ducts insulated or constructed in such a way that it conserves heat will save you a lot of money long term in energy bills. The most common ducts are pre-insulated, made of polyurethane or phenol insulation paneling. The old fashioned way to construct ducts is to create ducts with sheet metal then cover the outside part of the duct with insulation. But duct that are created from rigid insulation panels do not need a second coat of insulation on the outside, because they are insulated themselves. Ducts are sometimes suspending on ceilings and need to be lightweight in order to avoid collapsing. This give pre insulated ductwork made from aluminum ideal for large buildings or warehouse with exposed high ceilings. Before construction begins, have a qualified person draft the path design of your ducts. You want a duct system that efficiently creates air pathways to circulate in all the floors and rooms of the structure. Without a design blueprint to follow, contractors might miss a room or create unnecessary and redundant duct pathways. Once a design is clear, ductwork contractors will begin tracing the duct outline on metal sheets or pre-insulated panels, each section is joined at a forty-five degree angles. That means each joint will bend at a right angle, unless cut and designed to do otherwise. The parts are welded together or are sealed using aluminum tape or other sealant material depending on the material of your panels. For instance, fiberglass duct panels are pre-insulated but not metallic. These panels are attached together using staples and are sealed with tape made especially for fiberglass.
