Ways to improve ducts in an unconditioned attic

January 30, 2023 10:27 am Published by

The ductwork in your home connects the air handler for your HVAC system to the various vents. To keep it from decaying and posing issues for the air handler, it is wrapped with a grease duct fire wrap insulation. To allow you to cool or heat the air in your home as needed, the ductwork’s job is to transmit warm or cold air across the building. Before blown-in insulation is applied, the ducts in your attic should be air sealed with spray foam. Grease duct fire wrap refers to a duct used to vent combustible grease-laden gases from commercial cooking appliances such as stoves, deep fryers, and works to the exterior of a structure or mobile food preparation unit.

When building an HVAC system, attic ductwork might not be the ideal option, but if you are renovating an existing house or installing ducting in a house without a space between both floors, you may not have any other options. Most people are aware that the ductwork and HVAC system in your home should be in an area that has been air-conditioned, and studies suggest that ducts in an unconditioned area maybe 25% less effective at cooling your home, particularly in hotter regions. The reality is that many duct systems in freshly constructed homes that complete duct testing are leaky, and imbalanced duct leakage leads to more issues than losses attributable to the leak.

Listed below are a few ways to improve ducts in an unconditioned attic:

Position ducts on the lower side of the attic

It may get very heated in attics. On a hot summer day, an uncooled attic may get as hot as 120° F or maybe more. You may not be familiar with this, but attics aren’t often heated. An attic has the warmest air, whereas the region nearest to it has the most excellent air. Considering that it has the lowest temperature, the attic floor is where those ducts ought to be placed.

Seal your ducts tightly

Duct leaks can be a major issue if they are situated in an unconditioned attic. Even worse is leakage from imbalanced ducts, which are sealed with a lot of mastics. If you find substantial leaks in your ducting, it’s important to seal all the joints.

Increase the airflow in the ducts

When ducts are installed in an attic without air conditioning, the air that flows through them heats up during the summer. The more gently the air moves through the duct, the warmer the regulated air will get. With a lesser temperature rise every cubic foot, faster air movement distributes heat over a broader air volume. As a result, design the ductwork for faster air.

Watch out for mold

As heat rises through your home, moisture is carried into the attic. Adequate attic ventilation can help with this issue, but before any moisture-filled air is driven out of the space, condensation may form on the relatively cold HVAC ducting. When moisture condenses from the air, your attic’s ventilation system can no longer remove it efficiently, which can lead to mold growth.

The grease duct fire wrap’s ability to assist in venting combustible fumes outside of a structure or residence is its most significant usage. Grease duct maintenance is also a crucial component. The structure’s passive fire prevention system includes grease ducts. The fire code or other relevant safety rules frequently set the cleaning timetable.
