Rated 5.0 out of 5.0 by Pricey, but absolutely great product! Great product for decking your attic! Easy to install, goes in quickly. Easier to carry than the alternative of sheets of plywood! November 13, 2013
Rated 5.0 out of 5.0 by Excellent product. Needs to be sold in store (or store delivery option) and in larger quantities with greater discounts. Suggest installing 2x2's top of and at 90 degress to attic floor joists. This solves the problem encountered where the floor joists are not exactly 16 inches on center as well as having to deal with the problem of electrical wiring strung across the floor joists. Use a Attic Dek floor unit to set the spacing between 2x2's and all units will fit perfectly. It also gives you a much stronger and better supported floor than trying to make them fit between th floor joists. The extra cost in doing it this way is minimal compared to the savings realized in time and frustration involved in installing them the conventional way between the floor joists. April 29, 2014
Rated 4.0 out of 5.0 by Install hints and some precautions 1. Measure beam distance edge to edge, not center to center, there are centering tabs on the underside that of each panel that will make you crazy if you're off by even a 1/16th of inch. space needs to be 16"+. 2. Check to be sure your layout is across single beams, not overlapping 2x6's. You'll have to offset the panels if they are. 3. To break off the tabs, hold with a strong pair of pliers and bend the panel back and forth about 6 times then twist. Don't bend the pliers. 4. Buy more panels than you think you need; The Home Depot 20 pack is a very good deal. Don't be surprised if you get stiffed on the screws though, I got screws in one box only of 2 that I ordered. Replacements are 8x2" Countertop screws, available by the box at-- you guessed it. 5. Consider knee pads for installation, the pattern is painful to lean on for extended periods. 6. Power screw driver is a must. Overall a very nice product, esp if you have small access to the attic and can't fit planks up it. April 30, 2011
Rated 4.0 out of 5.0 by Great idea! These tiles go down quickly and easily and look great when done. Be sure to seal any gaps in the floor (partition walls, light fixtures) before installing. The ventilated design allows any moisture to evaporate instead of getting trapped under a plywood floor potentially causing mold growth. If the beams aren't quite 16" on center you can easily break the tabs off on the bottom to allow some movement before screwing them down. So far they seem very strong with only minor flex when walking on them. The price is the reason for 4 stars. These could easily add up to $1000 or more to cover an attic floor. I think the price should come down or allow for a larger bulk purchase than 20. February 19, 2011
Rated 5.0 out of 5.0 by Great product and easy to install I really like this product. In my last house I used cut plywood to make an attic deck and walkway, but I decided to try the Attic Dek this time. They are really light and easy to carry through the house and are easier to install than wood. They work great and are generally more expensive than plywood, but they are much more convenient - no cutting and hauling heavy wood upstairs to get to the attic. Also, there will be probably be a few areas in the attic where the studs are not 16" on center. I had to use some wood boards to cover those areas. I used 1x12 pine boards from the local Home Depot for those spots and it was fine. The pine was more expensive than the plywood, but I went for the convenience of hauling and cutting. I am ordering more of these tomorrow. January 14, 2014
Rated 5.0 out of 5.0 by Easy attic flooring. Easy to install. Rather epensive, but a great product. May 27, 2014
Rated 4.0 out of 5.0 by Definitely recommended This stuff rocks. I just installed about 20 of 'em in my attic. We had some critters up there nesting in the blown insulation, and I wanted sure footing when "walking the plank" through there. The nice thing about these Attic Dek panels is I was able to use them to install them, if that makes sense. Install one, then kneel on it while installing the next...and then the next, etc. They are not cheap, but it is SO nice being able to walk around up there now. The old plywood planks are gone.

Rated 4.0 out of 5.0 by Strong Product I think folks are beating up on the value b/c of the the freight costs. Each carton (20 pcs) weighs 57LB. These ship free freight. UPS is not cheap so there's at least $20 right there. On the other hand it is just plastic, but good plastic. The product itself is very good. I like that I can walk around the attic safely w/o fear of stepping on plywood the wrong way and getting hit on the head. I also like that is resting on the studs, not insulation -- so it is easier to breathe while working around the attic. Also since each panel is relatively small you can make adjustments where there are different elevations within attic. Also as others have said installation is a breeze. December 15, 2011
