How to Insulate the Ductwork in the Attic?

Day by day, summer is coming to an end, and winter may not be far off. As the temperature cools down, homeowners start to keep their houses warm. However, to keep your home warm, it is vital to keep all rooms warm. Since most ductwork is used to regulate hot air better, ensure that air ducts are properly insulated. Air Duct Cleaning in Suwanee GA services recommends inspections in-between seasons, so everything stays working.

There’s a chance that warm air can escape the ducts from the attic, so having it inspected with proper tools, like a laser thermometer, can be helpful. This way, you can be sure that ductwork is properly insulated, which could help reduce the expenditure of utility bills in winter.

Therefore, to get things started for checking and insulating air ducts, you can follow the steps below. However, before that, let’s go through the things you’ll need.

Things to get you started

According to Heating and Air Conditioning Service Suwanee GA, these are the thing you’ll probably need:

  • Laser Thermometer. However, it’s usually referred to as a thermal
  • Imaging Camera or Corresponding Smartphone Application. It’s easy to find one anyway.
  • Paintbrush from 1″ to 3.”
  • A sealant like Mastic or Air Duct Sealant
  • UL 181 Duct Tape. It’s perfect for insulation.
  • 10-10 Mesh that will help in insulation.
  • Masking Tape. It will help in the sealing process.
  • Eye Goggles for eye protection
  • Protective Gloves are the ones for working and keeping your hand safe.
  • Caulking Gun is a type of sealant, but you’ll need one other than the one mentioned before.
  • Silicone Tube, well, what will you put in the caulking gun anyway.
  • Ruler or inch tape and something for marking, like a pen, marker, or a pencil. You’ll need it.

Inspecting condition of attic insulation 

Some of you know that insulation can keep warm air in, preventing cold air from getting in. Before making improvements to your attic insulation, it is essential to know the condition of your ducts.

First of all, let’s start with gauging the current state of air ducts.

You can use a ruler to measure the ground-level attic insulation. It tells you where to begin checking insulation from. Then comes the laser thermometer to check for temperatures in the ducts. With that, you can detect temperature irregularities with ease.

Utilization of a laser thermometer

By pointing and pressing a button on a laser thermometer, you can quickly and easily determine the average temperature of an object or area. These thermometers are readily available and reasonably priced. These make it easy to identify and repair draught holes.

Check for drafts and temperature

Many Air Duct Cleaning Suwanee GA experts suggest starting checking the drafts and temperatures around doors, vents, windows, light switches, and another opening that you think may have issues. All you have to do is point and aim the laser carefully to get the actual reading to make sure there are no leaks. Like this, check the regions from where the drafts could enter. See places like lips of windows, areas in and around light switch panels, door jams, or ventilation shaft openings. Here, insulation may be weak and could affect indoor temperatures.

Use a sealant, especially a silicon-based one.

Additionally, The laser thermometer could also detect temperatures through walls. Therefore, it helps detect potential duct leaks in an HVAC system.

Thus, If you are thinking of an alternative to the laser thermometer, some Heating and Air Conditioning Service Suwanee GA use mobile-based apps like Seek that does the same thing. However, these smartphone applications are more expensive than traditional laser thermometers.

Additional insulation

Furthermore, you can use some insulation materials in those areas. Hence, You can use cellulose, fiberglass, recycled denim, or wool insulation for insulation ducts. Moreover, the duct system in the attic should be the primary focus, so the warm air cannot escape from there.

So, how can you do it?

Here are some easy steps:

Insulating up Those Leaky Duct Joints

Firstly, We know that ductwork is the backbone of air exchange and ventilation. Secondly, duct joint leaks often remain undetected, which is quite common. It happens because of rusting and eroding from elements like oxidation over a long period. It is usually because of ducts made of metallic alloy.

  1. Start by examining duct joints to find any damage or tears. The best way is by turning the HVAC system on. This way, you could quickly detect escaping air from ducts.
  2. If you discover a damaged or torn duct or joint, clean the area to prepare it for taping or insulating it. Use soapy water and a rag for this. A common mistake you could make is not cleaning the area properly, resulting in a poor seal, resulting in the leak staying the same.
  3. After carefully inspecting the surface, move forth with insulating the place with duct tape and affixing a piece of mesh carefully. Use mastic sealant or air duct sealant to close everything.
  4. For heating ducts, Air Duct Cleaning Suwanee GA recommends using caulk mastic for insulating. You could use a putty knife for this.

However, the most common mistake that most DIYers (do it yourself) make is failing to seal the joints with the right amount of caulking properly. Caulking isn’t cheap, so use the process effectively without cutting corners.

Post Work Inspection

Services like Heating and Air Conditioning Service Suwanee GA recommend checking back for post inspection after a couple of days. Use a laser thermometer or a smartphone application to not change or improve after the whole insulating process. You will notice that temperatures are now consistent. If any problem arises, repeat the steps above again, and see if you missed any spots. Don’t worry; it’s common to miss something. If needed, you could always call an HVAC technician or cleaner for inspection or professional consultation to get a second opinion.
