Sign Types and Materials: Interior Signage

Glad to see you back with us here at Miracle Sign Co. We’ve been working on introducing you to the sign types we offer and the materials we use in our family-owned sign shops in Forest Grove and Portland, Oregon.

As you know, signs are an important part of your commercial and residential needs – they say something about your business, event, and home. As with any form of communication, a sign needs to be clear. It also helps if your signage is easy on the eyes. And, all of this comes from a well-thought and well-designed sign. In our last post we outlined all the materials that go into making an exterior sign. Today, we’ll talk about interior signage.


Whether you’re looking for interior signage to both complement your business motif and fit its space or need a few sturdy signs to stand out from the rest at the annual trade show, Miracle Sign Co., has you covered. Just like exterior signs, indoor signage should reflect the best of your commercial and residential sign needs. From start to finish our family-run business and its team of sign experts work with you to produce the perfect signage.

There are several sign styles and materials to choose from and we’re happy to guide you along the way. What’s most important is knowing the purpose of your sign. Do you plan on using your signage as a directory? Or, perhaps to identify your business. Do you need a series of signs to show points of purchase in a retail setting?

At Miracle Sign Co. we understand that you want the best for your customers, returning and new – your business relies on this. Naturally, you need a building directory that is recognizable, informative, and understandable. Directories should also be attractive and complement your company’s design and visual theme. This is why we only use the high-end quality materials that work well indoors and get noticed by your customers and the public. Two interior sign materials that are also used outdoors are Dibond and Lexan. Dibond is a an aluminum composite that’s half the weight of aluminum and its makeup helps to produce stunning graphics. Lexan is engineered plastic that doesn’t peel, chip, or fade over time. It’s also shatterproof.

Another durable material available when designing a directory is frosted plexiglass. It’s lightweight, easy to work with, and a great alternative to traditional glass. Frosted plexiglass offers privacy where needed and yet it’s stylish and bright. Wrisco brushed aluminum is an excellent choice too for an urban industrial or contemporary look. Two traditional materials still commonly used in building directories are wood and glass. Both are timeless and elegant. The possibilities are endless as a  combination of two, three, or more of these materials can be used in designing your directory signage.

While building directories point people to places they need to go, your corporate identification says it all. Company logos, brand titles, or franchise symbols are the marks of your business and organization – it’s the first thing people should see when coming in through the front door. So, we only use the best of the best when it comes to your corporate identification indoor signage. Choose from acrylic, Sintra PVC, and aluminum.

An acrylic corporate identification sign presents a high-gloss finish. Acrylic is smooth, thin, and lightweight, making it easier to mount or install compared to traditional glass. It’s also perfect for lighted sign displays for a luminous effect. Sintra PVC is made from polyvinyl chloride, a durable synthetic material ideal for both interior and exterior signage. Sintra resists dents and scratches and like acrylic, it’s lightweight. Sintra PVC is a great choice for digital and screen printed graphics. A third option is aluminum. When used for interior signage, aluminum is long-lasting. It’s rustproof and waterproof too. Aluminum is extremely durable and projects a premium finish for your corporate identification.

We at Miracle Sign Co. also know the importance of your retail and point of purchase signage – these are the signs that impress your customer-base and drive sales. So, it makes sense that the level of quality, craftsmanship, and design of your retail and point of purchase signage is one of the most effective ways to increase the level of success for your business. In other words, promotional signage will only be as effective as its quality. Our sign team experts use a variety of high-end materials to produce high-end retail and point of purchase signs. One of our most versatile materials is Sintra PVC foam – we use it for both indoor and outdoor signage. Sintra is light, easy to cut, and is perfect for graphic displays. It’s also tough. Vinyl is another popular and reliable choice for sign layout and lettering. It’s cost-efficient, durable, long-lasting, and moisture-resistant. Vinyl is a type of polyvinyl chloride (PVC) – a resin plastic – made to resemble leather. Miracle Sign Co., only uses the most high-quality vinyl brands: 3M, Arlon, and Oracal. An added bonus to using vinyl is that it can be recycled.
