Will the glass wool insulation repel animals in the crawl space? Is 10 inch diameter the standard for home central heat and air units?
Hi Virginia, thanks for your question. We recommend using 4" or 6" diameter duct for your application. Unfortunately, glass wool insulation does not repel animals. If you have any other questions or concerns please do not hesitate to contact us.
What is the R Value of the cotton insulation in these ducts?
The R value of these ducts is around 3.5.
Can this duct be used for venting a range hood? It is 1000 cm a minute, so it's just domestic, but it travels 6m to the vent in the eaves, so I need something strong and heat resistant. It's over a gas cooktop with 800 clearance to the underside of hood.
Our insulated ducts with glass wool are mainly used in air-conditioning systems, and are not ideal for venting a range hood. We would suggest using D1146669-PVC Flexible Duct instead.
If I'm using this insulated duct under a mobile home, is the PVC harder for mice to chew or get into? I read and see it does not say rodent resistant.
Hi Diane. To answer your question, most of the flexible ductings are not rodent resistant. Our insulated duct is made with 2 layers of PVC compound fabrics and 1 layer of cotton, which means the thickness is 3mm. It could possibly still be chewed by mice and rodents, but it won't be able to be broken into as easily.
Is the diameter of insulated duct inside or outside?
The insulated duct has an outside diameter.
Can this insulated flexible 6" duct be used for bathroom vent through the roof ?
Hello Victor, thank you for your question. Our Glass Wool Insulated Duct can certainly be used to vent a bathroom. This duct can be used for an array of HVAC needs.
What is the R value of the glass/wool insulated flexible ducting?
Hello Michael, thank you for your question. The R value is 3.5. The glass wool has a thickness of 25MM. If you have any other question or concern please do not hesitate to contact us.
Does this duct come in any other colors?
Hi Simon, thanks for your question. The duct comes in three colors: yellow, orange, or grey. If you need assistance with your purchase, please call our sales team at 1-888-667-5776 or email at sales@deelat.com!
