4 Inch Insulated Flexible Duct,HVAC Insulation Duct,25 Feet Insulated Duct, 4 in Insulated Duct Hose, R4.2 Air Flexible Duct Aluminum Hose 4''25' Long,for HVAC Flex Ductowrk
【 High-quality performance 4 in insulated flexible duct】Made of thickened aluminum foil material and made of high-strength elastic spiral steel wire.The middle is covered with glass fiber insulation layer, which has high temperature resistance, acid and alkali resistance, and flame retardancy.
【 Owens Corning Glass Wool Insualtion 】Glass wool Insualtion is the safest building material, with high corrosion resistance and thermal insulation,R value: R-4.2. The temperature resistance range is -4℃~454℃.
【 Sound absorption and noise reduction insulation】 The internal structure of glass wool insulationis fluffy and the overall density is large, which can absorb the sound in time,Noise can be reduced by up to 85%.
【 4 inch insulated flexible duct】 It can be bent arbitrarily, without rigid elbows, the aluminum foil is self-sustaining and will not retract after installation.It can maintain the flatness in the tube and reduce the wind resistance.
【 Multi Function of the 4 in insulated flexible duct】Used for high, medium and low pressure ventilation system without corrosive gas. Mainly used in central air conditioning HVAC system,Fresh air ventilation systems, mechanical equipment recovery systems and other ventilation systems that do not contain corrosive gases, etc.
Great duct, absorbed 95% fan noise and thermal proof Great product with very reasonable price. Very easy to install on my new ventilation ducting to bring fresh air onto my bedroom, almost noise from the ducting fan disappeared since replacing this fibre wood one. So quiet I don’t even know the fan is on. Highly recommended
Tough Enough if you're careful The inner “foil” layer was much tougher than another reviewer said. It’s more of a “mylar” plastic silver mirror kind of material. I only needed 15 to 17 feet, so I didn’t mind ruining the end I attached to a rope for pulling through the hordes of black widows and rattlers. The insulation is as expected. I did tear the outer layer just a tiny bit pulling it with a rope I’d fish-taped through a confined crawlspace trench I had to hand-excavate. Attaching it firmly to the flanges worked well however the Hose Clamp, or Radiator Clamp style items supplied were some metric size I had no socket bit for. So, picture a guy on his back in dirt with spider webs hanging down trying to use a flathead driver on his drill to tighten a long long long clamp. One spider said: Hey, how-ya-doin?” I have patience. I attached it to one flange from inside the home, the other from underneath. Both ends were easier than expected. This is a quality product, but fragile as you might imagine. Be careful of it and it’s tough enough and a good value.
Great product at a great price! Great flexible duct at a great price point – a lot cheaper than the local hardware stores for the exact same thing. Fitment over my 4″ soffit vent it pretty tight, but it can be done. Insulation seems like decent quality. The interior duct itself seems durable too (I pulled it pretty hard to “stretch” it over the 4″ soffit duct and it went without ripping. Also came with 2 hose clamps which is just a nice addition (one less thing to worry about).
Now it comes vacuum packed and kind of coiled up. Once you open up the plastic it stretches out nicely (kind of like those memory foam mattresses). Easy to get to the shape that you want. The entirety of the duct was wrapped with insulation as well – so it doesn’t appear to be “cheap”.
Use – I’m personally using this for my bathroom exhaust vents. Running from the exhaust vent to the soffit vent with this line.
Overall – it’s great that this is available on Amazon – no dealing with the store, parking, ghetto people, paying higher prices at the store etc.
Its DuctingAnd It Does Exactly What Ducting Should Not much to say here: it’s 6″ insulated flexible ducting, and it did the job perfectly. Easy to work with, solid insulation, and exactly what I needed for my project.
Sometimes you just need something that works without any drama—and this delivered. Five stars!
