What Is The Best Method To Utilize Duct Insulation Wrap mmihomeimprovement.com/2022/06/21/what-is-the-best-method-to-utilize-duct-insulation-wrap
For air conditioning ducts, insulation is crucial. Many people, however, struggle to obtain information and instructions on how to choose and insulate ducts. As a result, we made the decision to write about it. To utilize duct insulation wrap, we must first choose the type of duct insulation and the thickness of the insulation. Then we must measure the duct’s circumference, cut the insulation to length, apply glue to both the insulation and the duct, and gently wrap the insulation around the duct. While the technique appears to be straightforward, several people are perplexed by the thickness of duct insulation. For air conditioning ducts, insulation is crucial.

To insulate ducts, we must first choose the type of duct insulation and the thickness of the insulation. Then we must measure the duct’s circumference, cut the insulation to length, apply glue to both the insulation and the duct, and gently wrap the insulation around the duct. It is vital to gain a better understanding of insulations in order to avoid purchasing the incorrect insulation.
How Do I Choose The Right Duct Insulation? Fiberglass and cross-linked polyethylene are the two most common forms of insulation. Because of its reduced cost, fiberglass is usually the selected material. Although polyethylene (PE) is more expensive, it is also safer and more attractive. Fiberglass is the best choice for insulating ducts that are positioned in the attic, above the ceiling, or inside the wall. However, if your ducts are visible under the ceiling and others can see them, you might choose to use PE insulation.
How Do I Know How Thick My Duct Insulation Is? Many individuals, including myself last time, struggle to determine the required insulation thickness. Although some energy-saving standards call for substantially greater insulation, most individuals insulate ducts to avoid condensation. To avoid condensation on ducts, the duct’s external surface temperature must not approach or dip below the air’s dew point. As a result, the dew point of air varies based on temperature and relative humidity. To put it another way, it is location-dependent.
Because condensation might happen shortly after you turn on the air conditioner, we should use the initial temperature and relative humidity values instead of the desired room conditions value when calculating the dew point.
Characteristics Of Insulation: When it comes to most insulations, you don’t want to compress or lower the thickness as much as possible. Insulation’s thermal conductivity of insulating capabilities is determined by its final thickness after installation. When 1′′ insulation are compressed to 1/2′′ thick, the insulations’ insulating capacity is effectively halved. Furthermore, air should not be allowed to accumulate between insulation and ducts. The insulations must be lightly pressed into the external surface of your ducts in all directions. Before gently pressing insulations against ducts, we usually apply dedicated insulation glues or adhesives to both the insulations and the ducts. When the air becomes trapped between insulation and ducts, it condenses into water droplets, which wets the insulations and reduces their thickness, lowering their effectiveness.

Thirdly, you should wipe your ducts with wet towels to ensure there is no dust and dirt staying on the surface of the ducts before putting on the insulation so that the insulations will stick onto the ducts. The above three things are essentials and basics when insulating ducts, pipes, and almost everything. Must Read: What Is The Best Time To Get HVAC Duct Cleaning Service
How to Insulate Ducts Using Fiberglass Insulation Before you begin applying fiberglass insulation to your ducts, it is critical that you comprehend the characteristics of insulation in general. Flexible ducts, in case you’re wondering, do not require external insulation because they are pre-insulated. Let’s have a look at how to install fiberglass insulation wrap on ducts step by step.
1. Measure The Circumference Of The Duct Measure the circumference of your duct. Just add the width and length of rectangular ducts and multiply by two. Measure the diameter of the duct, divide it by two, then multiply by 6.28 (the round circumference formula is 2r). If we have a 2416′′ duct, for example, my duct circumference is (24+16)x2=80′′.
2. Trim The Insulation To The Appropriate Length
Unroll the insulation and cut it to the proper length based on the duct circumference you just calculated. My duct circumference, for example, is 80′′, so we measure 80′′ and cut the entire insulation. Usage Of Roll Of Fiberglass Insulation The fiberglass insulation we mentioned earlier has a 48-inch width. As a result, when we trim it to 80′′ lengths, the fiberglass insulation is now measured as 8048′′, with 80′′ being utilized to wrap the duct and 48′′ being the duct’s length.
3. Adhere The Duct And The Insulation Together With Adhesive Apply adhesive to both the duct and the insulation once the insulation has been cut. If your insulations have an aluminum foil covering, you must apply glue to the fiberglass rather than the foil. Your ducts’ new external look is of aluminum foil. Because glue (liquid form) will drip if your ducts are hung up high. We recommend utilizing the spray adhesive. Because we insulate our ducts on the floor and glue is more cost-effective than the spray, we always utilize insulation glue (liquid form) instead of spray in projects.
4. Wrap The Insulation Around The Duct In A Gentle Manner Allow time for the adhesive to settle according to the manufacturer’s instructions. After that, enlist the assistance of a friend to help you wrap the insulation around the duct. It’s fine if you have crushed the insulation at the corner of the duct. The insulation should fit nicely on the duct with little to no additional length if you’ve measured and trimmed the duct circumference accurately. To help the insulation attach to the duct better, gently press it against it.

Wrapping duct junctions in fiberglass insulation is acceptable. You’ll need to cut and wrap the duct joints separately if you’re using PE insulation (cross-linked polyethylene foam).
5. Seal The Insulation Joint Using Tape After you’ve finished putting the insulation around the duct, cover the gap between the insulation joints with the aluminum tape we mentioned before. The tape should be large enough to cover the joint completely. Typically, we use 2′′ broad aluminum tape. Experts do not recommend other types of tapes for insulation.
6. Inspection The insulation should not appear to be sagging from the bottom of your ducts if you apply the adhesive and wrap it properly.
Conclusion: In conclusion, we can say that duct insulation wrap is an easy process. However, one should be very careful during it. Also Read: List Of Essential Dryer Repair Parts That Will Help In Troubleshooting
