Introduction
Choosing the right signage material is an important decision for any business. The material you select affects the sign’s appearance, durability, cost, portability, and suitability for different environments. Whether you need promotional signs for an event, temporary outdoor displays, retail signage, or a professional sign for your business premises, understanding the differences between available materials can help you make the right investment.
Three popular options are foam board, Coroplast, and acrylic signs. Each material offers distinct advantages and is suitable for different applications. Foam board is lightweight and ideal for indoor displays, Coroplast is a practical option for temporary outdoor signs and promotions, while acrylic provides a polished, professional appearance for business interiors, reception areas, and branded displays.
For businesses looking for custom signs in Calgary, selecting the right material starts with understanding where the sign will be used, how long it needs to last, and the impression it should create.
In this guide, we will compare foam board, Coroplast, and acrylic signs to help you choose the most suitable option for your business, event, or promotional campaign.
1. What Is Foam Board Signage?
Foam board is a lightweight display material made with a foam core between two smooth outer layers, typically paper-based or coated surfaces. Its relatively flat surface makes it suitable for high-quality printed graphics, photographs, illustrations, and promotional messages.
Foam board signs are commonly used in retail stores, offices, exhibitions, conferences, presentations, trade shows, and indoor promotional displays.
Benefits of Foam Board Signs
One of the biggest advantages of foam board is its lightweight construction. It can be carried, positioned, and mounted easily, making it convenient for temporary displays and events. Its smooth surface also supports detailed printed designs, allowing businesses to display colourful graphics, product images, logos, and promotional messages.
Foam board is particularly useful when visual quality is a priority but a heavy or permanent sign is unnecessary. Businesses can use it for product information boards, directional signs, menu displays, presentation boards, and point-of-sale promotions.
Another advantage is its versatility. Foam board can be cut into different shapes and sizes, depending on the intended design and the capabilities of the printing provider.
Limitations of Foam Board Signs
Foam board is generally best suited for indoor applications. Standard versions can be vulnerable to moisture, bending, denting, and damage from rough handling. Prolonged exposure to rain or harsh outdoor conditions can reduce their useful life.
Although foam board can be used for short-term displays, it may not be the best choice for signs that need to remain outdoors or withstand repeated handling.
Businesses should also consider the mounting method. Because foam board is lightweight and relatively rigid, it may require appropriate supports or a display stand to prevent it from falling or bending.
Best Uses for Foam Board Signs
Foam board is a strong choice for:
- Indoor trade show and exhibition displays
- Retail promotions and point-of-sale graphics
- Presentation boards and information displays
- Temporary indoor directional signs
- Event signage and photo displays
- Short-term product advertising
If your business needs an attractive indoor sign that is easy to transport and set up, foam board may be the right solution.
2. What Is Coroplast Signage?
Coroplast is a corrugated plastic sheet commonly made from polypropylene. It has two relatively flat outer surfaces connected by internal fluted channels, giving it a lightweight structure with more resistance to moisture than standard paper-faced foam board.
Coroplast signs are widely used for real estate advertising, construction notices, event promotions, temporary directional signage, election campaigns, and outdoor marketing.
Benefits of Coroplast Signs
A major benefit of Coroplast is its suitability for many short-term outdoor applications. The plastic material is moisture-resistant and can handle ordinary outdoor exposure better than standard foam board.
Coroplast is also lightweight, making it easy to transport and install. It can be printed with business logos, promotional messages, contact details, and directional information. The material is available in different thicknesses and sizes, allowing businesses to select an option that suits their display requirements.
Another advantage is its practicality for bulk campaigns. Businesses that need multiple signs for different locations can use Coroplast to maintain consistent branding across a promotion without selecting a heavier, more permanent material.
Coroplast can also be installed using suitable stakes, frames, or mounting hardware. For example, a real estate company might place signs near properties, while a contractor might use them to display project information at a worksite.
Limitations of Coroplast Signs
Although Coroplast is useful outdoors, it is not indestructible. Strong winds, prolonged exposure to sunlight, severe weather, and improper installation can damage the sign or cause it to move or fall.
The fluted internal structure can also affect mounting and cutting. Installers should consider the direction of the flutes when planning stakes, fasteners, and supports.
Coroplast typically provides a more utilitarian appearance than acrylic. While it can display vibrant graphics, it may not create the premium, polished impression required for a high-end reception area or permanent interior branding.
It is also important to distinguish moisture resistance from complete weatherproofing. The printed surface, edges, mounting system, and installation location all influence how the sign performs outdoors.
Best Uses for Coroplast Signs
Coroplast is suitable for:
- Real estate signs
- Construction site notices
- Temporary outdoor advertising
- Event and festival signage
- Directional signs for outdoor activities
- Short-term sales and promotional campaigns
- Community and local business advertising
For businesses that need affordable, lightweight signs for temporary outdoor use, Coroplast is often a practical option.
3. What Is Acrylic Signage?
Acrylic is a durable, rigid plastic material known for its smooth surface and glass-like appearance. It is available in clear, white, coloured, frosted, and other finishes, making it suitable for professional branding and decorative signage.
Acrylic signs are commonly installed in office reception areas, corporate interiors, retail stores, restaurants, clinics, showrooms, and commercial buildings.
Depending on the design, acrylic can be printed directly, decorated with applied graphics, cut into custom shapes, or combined with dimensional lettering and mounting hardware.
Benefits of Acrylic Signs
Acrylic is popular because it creates a clean, contemporary appearance. Its smooth finish can make company logos, business names, and other graphic elements look refined and professional.
The material is also rigid and more resistant to ordinary handling than foam board. With suitable thickness, mounting, and care, acrylic can provide a longer-lasting solution for permanent indoor signage.
Design flexibility is another advantage. Businesses can select clear acrylic for a layered effect, coloured acrylic to match brand guidelines, or frosted finishes for a subtle, sophisticated appearance. Stand-off mounts can create a floating effect, while layered panels can add depth to the design.
Acrylic can also be used for reception signs, room identification, product displays, menu boards, and branded wall signs. Its versatility makes it suitable for businesses that want signage to become part of their overall interior design.
Limitations of Acrylic Signs
Acrylic is usually more expensive than basic foam board or Coroplast, particularly when a project requires thicker panels, custom cutting, multiple layers, or specialized mounting.
Although acrylic is rigid, it can scratch, chip, or crack under certain conditions. It should be handled and cleaned carefully, using products recommended for the specific material.
Acrylic signs can also be heavier than foam board or Coroplast, depending on their dimensions and thickness. Larger panels may require professional installation and secure mounting.
Outdoor use is possible with appropriate acrylic products and a suitable design, but the material, print method, mounting hardware, and exposure conditions should be assessed before installation. Not every acrylic sign is designed for long-term outdoor use.
Best Uses for Acrylic Signs
Acrylic is a suitable choice for:
- Office reception and lobby signs
- Corporate logos and branded wall displays
- Retail and showroom signage
- Interior wayfinding and room identification
- Professional menu and information boards
- Layered signs with dimensional effects
- High-quality promotional and product displays
If you want signage that creates a premium impression and supports a permanent brand identity, acrylic is worth considering.
4. Foam Board vs. Coroplast vs. Acrylic: Key Differences
Although all three materials can display printed graphics and business information, their performance differs considerably.
| Feature | Foam Board | Coroplast | Acrylic |
|---|---|---|---|
| Weight | Very lightweight | Lightweight | Varies with thickness |
| Typical use | Indoor displays | Temporary indoor and outdoor signs | Professional interior and selected exterior signs |
| Moisture resistance | Usually limited | Generally good | Generally good, depending on product and installation |
| Appearance | Smooth printed display | Practical, promotional appearance | Polished, contemporary appearance |
| Durability | Best for short-term indoor use | Suitable for many temporary outdoor uses | Suitable for longer-term use with proper care |
| Portability | Excellent | Excellent | Depends on size and thickness |
| Custom shapes | Often possible | Often possible | Often possible with suitable fabrication |
| Relative cost | Usually low | Usually low to moderate | Often higher |
| Common applications | Presentations and indoor promotions | Real estate, construction, and event signs | Reception signs, retail branding, and corporate interiors |
The best choice depends on the project’s requirements rather than simply selecting the material with the lowest price.
5. Which Sign Material Is Best for Indoor Use?
For indoor signage, foam board and acrylic are often the leading options, although Coroplast can also be useful for temporary displays.
Foam board is ideal when a business needs lightweight promotional signs that can be changed frequently. It works well for trade shows, presentations, product displays, and short-term campaigns.
Acrylic is generally better for permanent branding, particularly when appearance matters. Reception signs, corporate logos, and retail displays often benefit from its smooth finish and professional look.
Coroplast can be suitable for indoor directional signs, temporary event displays, or areas where practicality matters more than a premium appearance.
Before choosing, consider how long the sign will be displayed, how often it will be moved, and whether it needs to complement the surrounding interior design.
6. Which Sign Material Is Best for Outdoor Use?
Coroplast is often a practical option for temporary outdoor signs because it is lightweight and moisture-resistant. It is commonly used for property advertising, construction notices, and short-term promotions.
However, the installation environment matters. A sign exposed to strong winds may require a stronger frame, suitable stakes, or a different material entirely. Larger signs also need appropriate support to reduce the risk of movement or failure.
Acrylic can be suitable for certain exterior applications when the correct material, print method, and mounting system are selected. For permanent outdoor signage, businesses should discuss exposure to sunlight, temperature changes, moisture, and potential impact with their sign provider.
Standard foam board is generally not recommended for prolonged outdoor exposure. If an outdoor display needs to last beyond a brief event, consider whether a more weather-resistant material would provide better value.
For businesses in Calgary, local weather conditions should be part of the decision. Wind, snow, road grime, temperature fluctuations, and seasonal sunlight can influence the performance of signage and its mounting system.
7. How to Choose the Right Material for Your Budget
Budget is important, but the lowest initial price does not always provide the best overall value. A sign should be assessed according to its intended lifespan, appearance, installation requirements, and replacement frequency.
Foam board may be economical for a one-day event or a temporary indoor promotion. Spending more on a permanent material may not be necessary when the sign will only be used briefly.
Coroplast may offer a practical balance for outdoor promotions that require several signs across different locations. Its lightweight structure and moisture resistance can make it useful for short-term campaigns.
Acrylic may involve a higher upfront cost, but it can be a worthwhile investment for reception areas, retail interiors, and other locations where signage remains on display for an extended period.
When comparing quotes, ask what is included in the price. Printing, custom cutting, finishing, mounting hardware, design services, and installation can affect the total project cost.
It is also helpful to request material samples or photographs of completed projects. This makes it easier to compare finishes and determine whether the material suits your brand.
8. Consider Design, Printing, and Installation
The material is only one part of successful signage. The design must also communicate clearly and suit the location.
Use readable typography, appropriate colour contrast, and a clear visual hierarchy. The business name or main message should be easy to identify, while secondary information should remain legible at the expected viewing distance.
For promotional signs, focus on one main message rather than trying to fit every product or service onto the panel. For corporate signage, maintain consistent logo proportions, brand colours, and typography.
Printing quality also matters. High-resolution artwork, suitable print methods, and proper finishing can improve the final appearance. For acrylic signs, consider whether direct printing, applied vinyl, or layered elements will best achieve the desired look.
Finally, select the right mounting method. Lightweight signs may need simple stands or temporary supports, while acrylic panels and larger displays may require secure hardware and professional installation. A sign that is poorly mounted can look unprofessional or become unsafe, regardless of the material.
9. Common Mistakes to Avoid When Choosing Signage
Businesses can avoid unnecessary expenses by considering the intended use before ordering.
One common mistake is selecting foam board for an outdoor location where moisture and wind can quickly damage the sign. Another is choosing Coroplast for a premium corporate reception area when a more polished material would better represent the brand.
Some businesses focus only on the material price without considering mounting, installation, replacement, and maintenance costs. Others choose a sign that is too small or includes too much text, reducing its effectiveness.
It is also important not to assume that every plastic sign material performs the same way. Foam board, corrugated polypropylene, and acrylic have different structures and limitations.
Before approving a project, confirm the material, dimensions, thickness, print finish, intended location, mounting requirements, and expected service conditions with your sign provider.
10. Where to Get Custom Signs in Calgary
Selecting the right sign material can be easier when you work with an experienced signage provider. A professional team can review your requirements, recommend suitable materials, and help you balance appearance, durability, and budget.
Businesses looking for custom signage in Calgary should consider the purpose of the sign, the environment where it will be installed, the expected lifespan, and the impression they want to create.
Whether you need foam board displays for an exhibition, Coroplast signs for an outdoor promotion, or acrylic signage for a professional reception area, choosing the right solution can help your message stand out.
