Rated 5 out of 5 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 5 out of 5 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 out of 5 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 4 out of 5 by Clever solution for oddly-shaped attic Our home's attic space was apparently never intended to be visited much. It's an oddly-shaped area where you can't stand up fully -- or even half-way in some places. Electrical wiring and fire-suppression piping run every which way. The attic is accessible only via a smallish opening in the ceiling below. Add to this having to balance on wooden beams to get around up there. There was a real risk of stepping through the ceiling. Getting plywood flooring sheets into such an area would be a major chore, let alone cutting each piece to size / re-routing the electrical wiring and sprinkler pipes. That's where these "Attic Dek" squares fit in. They're small enough to fit through the entry to my attic. They're also cleverly-designed to fit between standard 16" on-center joists. Also, each Attic Dek "tile" can be placed around existing wiring/plumbing to provide something to stand on. Five deck screws are provided with each tile. My only complaint with these Attic Dek tiles is at ~$100 per box of 20 they're not inexpensive. I would say that you'd use these tiles to provide a "catwalk" to get around to key areas in an oddly-shaped attic space, not to serve as a complete attic flooring solution. Although my attic is still a challenge to get around in, with these Attic Dek tiles it's a lot easier than it used to be! September 2, 2014
Rated 4 out of 5 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
