Regarding commercial buildings and facilities, exterior glass doors are a common feature due to their aesthetic appeal and the ability to allow natural light inside. However, these doors pose significant security risks, as intruders can easily breach them. Various security options are available for commercial exterior glass doors to address these concerns. This blog will explore these security options’ good, bad, and ugly aspects, highlighting their effectiveness and limitations.

The Bad: Standard Annealed or Tempered Safety Glass

Many commercial buildings utilize standard annealed or tempered safety glass for their exterior doors and windows. While these glass types are commonly used, they do not effectively protect against forced entry attempts or other threats like vandalism or storm damage. Annealed glass, the most common type, lacks the strength to withstand significant impact. Tempered safety glass is more robust but vulnerable to determined intruders.

The Good: Security Glass Systems

Security glass systems offer a viable solution to enhance the security of commercial exterior glass doors. One such option is laminated glass, consisting of two sheets of annealed glass bonded with a special interlayer. This interlayer provides increased strength and impact resistance, making it difficult for trespassers to penetrate the glass.

Another effective security glass solution is DefenseLite, a secondary glazing system made of custom-fabricated polycarbonate. This “security glass” is installed onto existing glazing, creating invisible protection against forced entry attempts, vandalism, and extreme weather conditions.

Security window film is another option worth considering. Applied directly to the existing glass, this film enhances the strength and shatter resistance of the glass, delaying or deterring potential intruders. It is also effective against blasts, severe weather, and earthquakes.

The Ugly: Insufficient Security Measures

While improving the glass itself is crucial, relying solely on security glass may not provide optimum security. To ensure comprehensive protection, it is essential to implement additional security measures such as commercial door locks, access control systems, alarms, cameras, and sensors. These components work with security glass systems to create a robust security infrastructure.

How Can a Professional Commercial Glass Door Company in NYC Help?

Here are some ways in which a professional commercial glass door company can help:

Enhancing Aesthetic Appeal: Commercial glass doors offer any business space a modern and professional look. They create an open and inviting atmosphere, allowing natural light to enter the premises and making it more welcoming for clients and employees. The sleek and contemporary design of glass doors adds a touch of elegance, giving your business a competitive edge.

Maximizing Natural Light: One of the significant advantages of commercial glass doors is the influx of natural light they allow into the interior space. Natural light has been shown to improve mood, boost productivity, and create a positive working environment. By maximizing natural light, businesses can reduce the dependency on artificial lighting, resulting in potential cost savings on electricity bills.

Energy Efficiency: Modern commercial glass doors are designed with energy efficiency in mind. They are often equipped with insulated glass, which helps control temperature and reduces energy consumption. By minimizing heat transfer, these doors can contribute to maintaining a comfortable indoor environment and reducing HVAC costs.

Improved Safety and Security: Commercial glass doors can be made with tempered or laminated glass, which enhances their strength and resistance to breakage. It improves the safety and security of the office by deterring burglars and providing better visibility of activities happening in and around the premises.

Easy Maintenance: Glass doors are relatively easy to clean and maintain. They are resistant to scratches and stains, and regular cleaning can keep them looking pristine.

Customization Options: Professional commercial glass door companies offer a range of customization options to meet businesses’ specific needs and aesthetic preferences. Companies can choose designs that align with their branding and style, from different glass types to frame materials and finishes. 

Increased Brand Visibility: Commercial glass doors with clear or tinted glass can provide visibility to passersby, allowing potential customers to see into the business premises and showcase products or services. This increased visibility can attract attention and contribute to brand awareness.

Sound Insulation: Some commercial glass doors are designed with soundproofing properties, which can help reduce noise transmission between office areas or external sources. It can create a quieter and more focused work environment.

Expert Installation: Professional commercial glass door companies have the expertise and experience to ensure the proper installation of glass doors. They understand the manufacturer’s recommendations and consider local climate factors to ensure the doors are installed correctly and withstand temperature fluctuations.
