How to Select

How to select Flex Ducting

Installing flex ducting in a house is very necessary for safe and easy connection of all air ways and corners of the building. Moreover, flex ducting reduces the number of unnecessary elbows thus increasing the efficiency of the system. Selecting the necessary ducting parts and accessories is always complicated, especially for people who don’t know what to look for. This guide will help you select the best flex ducting supplies for your home.

An essential part of every ducting system is flexible duct. This is the tube that connects all of the inputs and outputs and provides space for air circulation. To know what type of such ducting you need, you have to size the flex work appropriately. Correct calculations will make the air volume flow through the system properly thus providing every room of your house with fresh air.

Square footage of each room is the first detail to calculate. Next step is figuring out the CFM rating that corresponds to the room’s area. CFM is the amount of air that is required per a square meter of the area. This means that to receive proper ventilation, a 50 square foot room will need 50 CFM of air volume. Now, to calculate the flex ducting size, use the online calculator.

When you have specified the ducting size, you may need to calculate its length if you haven’t done it previously. Simply measure the perimeter of the room or the area where the flex ducting will be installed.

The next step in selecting Flex Ducting is deciding which construction material to use. The most common types of duct materials are: vinyl coated flex, fiberglass or galvanized sheet metal. Fiberglass offers better insulation, galvanized metal is perfect for industrial and commercial installations and flex ducting features easy installation.

Selecting the right ducting fittings is crucially important. You need to ensure that such fittings are compatible with the flex ducting and in addition to that provide gap and slot free connection. If the air is slipping through the connections, more energy and money will be spent to push it through the system. To prevent such thing from happening, install your ducting and all of the additional fittings with efficiency in mind.

Special devices, such as fans, air-conditioners and coolers, provide the air circulation through the duct system of the building. To select perfect devices for your particular system, you need to pay attention to their power, safety, control options, design and quality.
