Thank you for your question. For the sides of the garage we would recommend our Vinyl Garage Door Seal for Top & Sides (model number 03822). This product can be cut to size as well. If your local Home Depot does not stock it, you can special order it from their Pro Desk.

The product is good. The picture made it look a lot wider than it actually is, so I will not be able to use it in my original application, but I will be able to use it in another I am sure.
