Security grilles help protect storefronts by deterring criminal activity and are available in either a roll-up or side-folding design. Each has its pros and cons, especially when it comes to space, visibility, and operation. Here’s everything you need to know to choose the right security grille for your retail space.

 

Understanding Security Grille Types

Here’s how the design and functionality of each security grille type differs:

Roll-up security grilles, or rolling grilles, operate by rolling up and down vertically. When closed, the grille curtain stores in an overhead coil supported by guide extensions.

Rolling grilles are ideal for openings with limited sideroom. These can be used to protect windows, countertops, storefronts, and control access to hallways and employee-only areas. Rolling grilles can fit standard openings up to 40 feet wide and 20 feet high, but can also be customized for larger openings.

Side-folding grilles, or sliding grilles, are made up of connected panels that fold to the side and stack neatly at one or both ends of an opening. The panels slide along a track on the wall or ceiling, like an accordion. You push or pull the panels along the track to open or close the grille.

Side-folding grilles are typically installed in storefront entrances, but can also be used to secure expensive merchandise displays, cashier stations, inventory storage areas, and as temporary dividers in large retail areas. 

One of the biggest advantages of security grilles is their ability to be customized, as they come in various styles and offer a range of operational, safety, and security features.

Design Innovations and Aesthetic Options

What sets Clopay rolling grilles apart from others is an unbeatable range of customization options. Grilles are available with a ton of aesthetic choices, allowing you to select a curtain pattern, paint and finish, trim package, and even custom etching to show off your logo or branding. Plus, Clopay grilles are "made-to-order," which means you can choose the size and dimensions that work best for you. Some grilles are designed so they can support themselves, which means you can install them even before the walls are completely constructed.

 

Of course, balancing aesthetics with security is never easy. You don’t want to cause customers or passerby agita. Luckily, Clopay roll-up grilles have plenty of options to help you find perfect harmony between your design and peace of mind.

Clopay rolling grilles are available in these popular materials and finishes:

• aluminum
• steel
• stainless steel
• 316 stainless steel
• galvanized steel
• dark anodized
• clear anodized

For added security, you can get a Lexan insert. Lexan is made with clear and durable shatterproof plastic and placed in the open spaces of the grille curtain.

Safety Features and Compliance

Clopay roll-up security grilles comply with building codes and provide users with reliable daily protection and ease of use. Standard and available safety features meet egress requirements and prevent injuries. Available on all rolling grilles is a manual release system, a wall-mounted pull handle that disengages the motor, partially opening the grille for egress.

Other available safety and protection options can include:

• guide mounted interlocks
• sensing edge
• light curtains
• entrapment protection devices
• lock options

Whether you’re beefing up your grille with safety features or not, you’re guaranteed a long-lasting product. Clopay security grilles are incredibly durable and come with a standard two-year warranty on the operator and components. Warranties can vary, so check product details for exact warranty terms.

Business Security Solutions for Different Environments

As we move into 2025, retail design is changing, with an increased focus on sustainability, adaptable multi-use spaces, and an emphasis on community and customer comfort. To compete with online stores, brick-and-mortar retail spaces need to give customers a reason to leave their couch.

 

Modular retail spaces are trending, and it’s no surprise why. These designs are flexible and cost-effective, letting you change the layout without incurring the cost of renovation. These spaces need strong yet subtle security solutions like the Visionaire® MicroCoil® Grille, which requires 40% less headroom than standard grilles.

Multi-use spaces encourage community, combining retail therapy with areas for relaxation, workshops, group fitness classes, pop-up events, and more. Due to increased foot traffic, these spaces come with access control challenges. The SteelWeave™ MetalMesh Grille is the most attractive solution available, with delicate patterns woven into the grille curtain. Along with an elegant appearance, this security grille is incredibly strong, thanks to its 316 stainless steel construction.

Another popular option for retail spaces are Visionaire® & VistaGard™ Grilles. These models use 30% less headroom than standard grilles. A patented link design reduces operation noise and contributes to the lifecycle of the grille, which operates at a notable 50,000 cycles.

Choosing a security grille isn't easy, especially with so many models and options on the market. Luckily, Clopay makes the decision easier with flexible designs and endless customization.
