I wonder if any of the companies that build wooden pallets invested in Pinterest? If not, they should at least write the company a really nice “thank you” note because wooden pallets have all of a sudden become a sincerely hot commodity–at least it is for anybody I know that is on Pinterest. While all of this Pinterest interest in the product is due to the DIY handiness & upcycling bragging points, my interest in a wooden pallet is more for the storage industry. Wooden pallets are one of a few things that help promote good air circulation in a storage unit. Air circulation might not sound like much, but it is important for your unit and there are several ways to help promote it.
First, you guessed it, would be wooden pallets. If you put your items on top of wooden pallets you are getting everything off of the floor and are allowing air to travel underneath through the slats. This is also helps get your things off of the cement slab which can be cold and in some cases damp.
Next, leave walkways in your unit. Leaving walkways will not only help keep air flowing within the unit, but it will help promote easy access of your items throughout the space.
Some say leave a full walkway down all of the walls of your unit as well. While it would be nice to have this and it is a recommendation if possible, I think you’d be okay with just leaving a minimum of a 3 inch gap. I can see where people might not want to give up that much space in a unit to create that many walkways.
Air flow helps to reduce the risk of that musty, dingy smell that is caused by mold. Stagnant air can be tough on items and can make accessing your unit unpleasant. So see what you can do to increase air flow in your unit. Leave walkways, space between the wall, and if you get to wooden pallets before all of the Pinterest people, use those as well.
