Ducts & Vents

When it comes to adding a run of ducting and register to a cold room, you should be able to perform the work without the help of a pro. The first thing you need to know if that you should use rigid duct as much as possible. You’ll find several different diameters of rigid duct; measure the room you’re heating and install the recommended size. Flex duct – flexible plastic duct joined with a metal coil- may be easy to install and works well in certain situations but sags and turns can severely restrict airflow and sometimes deliver no heat at all.

Elbows also restrict airflow but are absolutely necessary. An adjustable, round metal elbow is built like a piece of lightweight armor and adjusts from straight to 90 degrees. Rotate the ends to get the desired angle. Duct work is held together with sheet metal screws and sealed to prevent loss of air through joints and seams. Sealing the joints and seams properly can result in significant savings on heating and air-conditioning bills. Even though it’s called duct tape, duct tape Is not an efficient or long-0lasting solution and should not be used as a sealing agent. Duct mastic and foil-backed tape are the two basic solutions to sealing your duct work.
