HDU Sandblasted Signs Superior to Wood
These days, high density urethane foam is the newest advancement in high quality signage. Businesses are using this petroleum-based foam for their signs instead of traditional high quality woods. HDU is popular, but is it really better than wood?
What Is HDU?
High density urethane (HDU) is a foam product that was designed specifically to make signs. It is flexible, durable, and can be made to look just like wood. The term “foam” may make you think about porous material full of air, but it is much thicker than most types of foam.
Traditionally, sandblasted signs were made of high quality wood. These are attractive, but they can be quite expensive. Wood also shows wear and tear over the years, and the added cost of replacing them every few years makes them even more expensive.
The Effects Of Water
The greatest advantage of HDU over wood is that it is naturally waterproof. Water is the number one destroyer of wood signs. Humidity bends and warps wood, and it can be noticeable in just a few short years, depending on the climate where you live. When a wood sandblasted sign is chipped, this allows water to get inside, and it can begin to deteriorate from the inside out.
HDU doesn’t have this problem. It is naturally waterproof because it is a petroleum based material. This means that HDU lasts longer than wood and doesn’t need to be replaced over time.
The Effects Of Wind
Although HDU is durable, it is lighter and more flexible than wood. This means that it can be effected by wind. If you have a long, thin HDU sign that is stretched between two posts, windy weather can bend it and permanently damage it. This is one thing to keep in mind when deciding whether it is right for you.
