The most common uses of foam include:
Making a rugged customized carrying case / accessory case from one of the cheap aluminum cases available from the larger stores is cost effective and easy. Polyethylene foam is often used as it doesn't retain gases, doesn't hold moisture, and its compression properties will hold your valuables very well.
Today we see more and more new homes and buildings that are being insulated and decorated with shapes cut from foam. Hundreds of different architectural shapes like moldings, trims, bands, cornices, sills, balusters and columns are easily cut to supply this large industry.
Foam is one of the best and least expensive packaging materials used to protect products. Packaging customers often need large numbers of the same shape.
Reupholstery such as reupholstering any piece of furniture changes the look and appearance of the furniture and increases its lifespan. Simply replacing the foam padding on any older piece of furniture or vehicle such as a couch, seat, chair, or stool is a very common use of foam. More about using foam for reupholstery.
