Questions & Answers

Does this flex duct contain an added or secondary vapor barrier to prevent outside moisture infill caused by condensation in very humid areas?

Asked by: meltillis
No, this stuff gets saturated from moisture if it is used in damp or wet crawl spaces and not much ventilation, then looses much of its insulating properties. Found a better solution for use in damp or wet areas, which resolved the problem we had with moisture soaked insulation in damp/wet crawl spaces with very little ventilation/air flow under the house: ........................................................................................................................................................................................................................................http://www.homedepot.com/p/Reflectix-16-in-x-25-ft-Double-Reflective-Insulation-with-Staple-Tab-ST16025/100012574 .........................................................................................................................................................................................................................................http://www.homedepot.com/p/Reflectix-48-in-x-100-ft-Double-Reflective-Insulation-BP48100/202092205

specifications stte that the 7" duct is 8 diameter and height is 11"; is "height the diameter including the insulation

I need to run 20' of the 7" duct between the 'rim" joist and the "adjacent" interior joist (space is 14-1/2"). The foundation wall line (wall that bears the rim joist) has a separation of 8-1/2" from this "adjacent" joist. Can the duct be temporarily compressed to pass through the 8-1/2" space without causing permanent deformation?
Asked by: RL133
The internal pipe is 7''. The outside diameter is pretty large. Did not measure it, but looks like about 11''.

Rated 5 out of 5 by from Great Product! We had to replace the ducting in our finished basement as the previous owners/builder had not put insulation around the metal A/C ducts before finishing the basement, and the metal ducts were having a serious condensation problem causing spots of moisture and eventually mold on the ceiling. We cut out all the drywall in the affected areas on the ceiling and pulled out the full length of the metal ducting and replaced it with this product. It was a perfect fit and you can tell this is a quality product. The hardest part about this whole project was patching up the ceiling. =)

Rated 5 out of 5 by from flexible and easy to use I used various sizes of Master Flow Flexible ductwork when installing my furnace. The 7 inch ductwork is as tough and flexible as the 12 and 8 inch sizes. When installing this ductwork on Master FlowStarting collars, installation is fast and very secure. The ductwork is very flexible and able to snake through tight spaces. I definitely recommend this ductwork.
