Exterior HVAC Insulation - Wrapping Ductwork with Foil Insulation
This entry was posted on December 12, 2016.
This is great customer project to share. Thanks H .J for sharing your photos. H.J. wanted the HVAC lines running to his metal building located Southwest of St. Louis, Missouri insulated.
InfraStop® double bubble foil insulation is a perfect product to use as it is inexpensive, easy to work with, performs well, and is impervious to moisture.
H.J is very detailed as you can see in the pictures he sent over of this project. Prior to ordering, we discussed his project and shared ideas on how to best insulate his exterior HVAC lines. From here you can see how he insulated the lines from start to finish. Look at the pieces he cut to work the 90 degree elbows. What a great project!
We explained the 3 different options available when working with double bubble foil insulation and the different R-value’s associated with each option.
Option 1 (all seams taped, maintain airspace): Loose wrap the insulation, R-4.1 Option 2 (all seams taped, maintain airspace): Wrap the insulation around spacers, R-6.0 Option 3 (all seams taped, maintain airspace): Wrap insulation around spacer 2 times, R-8.0
Thanks again H.J for the photos and sharing your project. This perfectly demonstrates how to insulate HVAC duct work located outside.
