I ordered 2 boxes, each containing 8 foam tiles, for our double garage door. Tools required are a sharp utility knife, measuring tape, straight edge and a marker of some type. Make sure you use a new blade in the utility knife for easier cuts and less mess. Look at your garage door and remove any hurricane bars, lock chains, handles etc which might be in the way. In my case I simply had to unattach the locking chain from each side and remove its rotating handle in the center by removing a pin. Once the project was finished attach each end and reinstall the handle.As for the install it took me maybe 90 minutes total with my 4 year old son helping. :) I did the two center columns first starting with the center four then the top center two and the the bottom. The left hand column came next then over to the right hand side to complete the door. The left hand side and both center columns fit recessed in tightly behind the frame lips at the top, bottom and left side while the right side slides straight in flush with the frame. The right column has recessed edges on all four side which doesn't work and is noted in the instructions. I cut four pieces at 2.5" which fit behind the right side of the column flush with edge. Next cut the panels as the rest it fit in the right, top & bottom recesses and flush in tight beside the smaller 2.5" piece. I did not have to but decided to run a length of duct atone from top to bottom in those four right hand areas over the joint. Just a personal choice and wasn't required. Neatly done and hardly noticeable.The tiles are extremely durable and bendable! I'd start at a slight angle inserting the top left edge first and as much as possible then bending or cupping the panel insert the bottom left edge while straightening it out. Once most of the panel was inserted pull the right side out away from the hinge brackets and slide in towards the left and behind the lip. Bend the top in followed by the bottom until you finally fit the right side edge in. Watch the hinge brackets when you slide the panels so they don't catch and tear the slotted side corners. They are so durable and bendable that they can fit extremely tight. I cut the first 3 columns at 45 13/16th inches (instead of just cutting at 3/4") and the right edge fits in snugly against the frame. You couldn't slide a sheet of paper between any of the edges. So when cutting and fitting in cut to the exact size for a perfect fit!The laminated side looks great in our otherwise roughly finished garage which badly needs a painting! I was amazed at the easy & quick install, how durable the panels were, how tight they could fit in and that they could look as good as they do. The final raising and lowering test of the door showed that the panels remained in place with no movement. Perfect!I have 100% total product satisfaction with this! Completed photo included. I'd have moved the cars out but it was too cold to bother with. Enjoy!
