CUSTOMER REVIEWS

Rated 4.2 out of 5 by 5 reviewers.
Rated 4 out of 5 by Great product, only comes with 5 sides... This duct board plenum kit worked perfectly for my application. I purchased 3, because I had to get the extra sides to build 2 complete boxes, which is my biggest complaint. the only way I knew it was not a complete box was because another reviewer mentioned the same thing. I used 1 box as a supply sub-plenum, 25 ft away from the main furnace supply plenum. 14" flex run in, (3) - 8" flexes out, split to (6) 6" register connections. I used the other box as a return sub-plenum, 35 ft away from the main furnace return plenum. 14" flex run to the box, branching to (4) 8" flexes to return runs in stud cavities. The boxes were easy to assemble once I figured out how to do it, although it takes a while to build them. Comes in 3 "pieces", which make up 5 sides. 2 of the pieces are ready to fold into a half square, with 2 corner seems to tape completing the square. The 3rd piece is an end, with all 4 edges to tape. Fabricating a 6th side from the 3rd plenum kit was easy, just took a side with 3 "beveled" edges, and added a 4th bevel edge using a utility knife. Cutting material is very easy and clean. Used a utility knife with a sharp blade, cuts through like butter. In order to cut completely through the thick material, I used a sharp lock blade knife to finish the cuts. Minimal mess, easy to cut clean holes, no "sawing" required. I would choose to work with this material over sheet metal any day. One more thing. Material is itchy hard fiberglass. Use gloves, try not to get it on your skin. December 15, 2013
Rated 5 out of 5 by nicely engineered building and installing the plenum and ductwork in a 100 year old house couldn't have been easier. The plenum is in pieces that fit perfectly together. needed to adjust the size to fit between floor joists and it cut smooth as silk with a utility knife. much sturdier than I expected, a pleasant surprise! seal it well with foil tape (I used three layers because I had extra tape). cuts easily with a hole saw or jig saw - and I used both. it might have been nice to have assembly instructions but I had it figured out in two shakes - and it made perfect sense once I understood the way it was fasioned to fit. very light weight and easy to position.

Rated 5 out of 5 by Looks like a pro did it. This is a good product. It is easy to cut with a utility knife if you need to modify the size. The price is a little spendy. October 16, 2012
Rated 4 out of 5 by Easy to tape together The only down side is this box has no bottom section incuded. I bought these to make a collector box for my returns. ( 14" in and 4 ~8" out. So had to buy a third box to get the end sections needed to complete the box I was looking for. I went with R-8 flex runs so also wish this was offered in something thicker to have a higher R value. Over all happy with the item April 10, 2012
Rated 3 out of 5 by Felt layer to thin. Kudos for home depot for carrying this product. I used it for a return air plenum for three seperate returns. My chief goal was to elimanate noise from my furnace fan and I have no noise chiefly due to this product, duct board registers, extruded aluminum filter grills, and ~13 ft 8 inch flex duct on two returns with 25 feet on a 12 inch run (all probably could have been shorter). The plenum was the big noise silencer. Take care with the collars you use with this product. The inner felt layer is thin. I am no expert, but I had a register box with a 1/4 inch felt layer where the collar went through which worked great. With a thin layer, you may have tufts of insulation sticking out around your collar in the flow of the air. I used aluminum foil tape to shield this exposed insulation, but since this was used as a plenum it will not be easy to verify that the tape does not break lose in the future, creating a health hazard (especially if you've got filter grills with no filter to capture any fiberglass fibers breaking lose in the ducts.) I am elated with the overall project as it is dead silent. May 15, 2012
