Choosing the Right Protection: Glass vs. Polycarbonate Skid Steer Enclosures
by Nathan Biser
When it comes to upgrading or repairing a skid steer cab, the decision usually comes down to two primary materials: tempered glass and polycarbonate.
While both serve the fundamental purpose of keeping the operator out of the elements, they offer very different benefits in terms of safety, durability, and long term maintenance. Understanding the specific demands of your daily work environment is the most important factor in choosing which material is right for your machine.
Tempered glass is the industry standard for most general applications. It is the same type of glass used in automotive side windows. One of the primary advantages of tempered glass is its incredible surface hardness. Because it is highly resistant to scratches, you can use windshield wipers frequently in muddy or dusty conditions without worrying about the surface becoming cloudy or pitted over time. This makes glass an excellent choice for landscaping, snow removal, and general agricultural work where visibility is a constant priority.
From a safety perspective, tempered glass is designed to break into small, relatively blunt pieces rather than sharp shards. However, it is still susceptible to shattering if it is struck by a heavy object or a high velocity piece of debris. For operators working in environments where there is a low risk of flying projectiles, glass is often the most cost effective and practical solution. It remains crystal clear for the life of the machine and is easy to clean with standard glass cleaners.
Polycarbonate, often referred to by brand names like Lexan, is a much more specialized material. It is a high grade plastic that is significantly lighter than glass but offers vastly superior impact resistance. In fact, polycarbonate is nearly unbreakable. This makes it the preferred choice for high risk applications such as forestry, land clearing, and demolition. If a piece of wood or a stray rock flies toward the cab, a polycarbonate door will flex and absorb the impact rather than shattering. This provides a critical layer of protection for the operator in dangerous environments.
While polycarbonate is exceptionally strong, it does have some drawbacks that operators need to consider. It is naturally softer than glass, which means it can be scratched more easily. If you are working in an environment with a lot of grit and you use your wipers frequently, the surface can eventually develop fine scratches that impair visibility. Most modern high quality polycarbonate doors come with a hard coat finish to mitigate this, but they still require more careful cleaning. You should never use harsh chemicals or ammonia based cleaners like Windex on polycarbonate, as they can cause the material to become brittle or yellow over time.
Cost is another factor that often influences the decision. Generally, a standard tempered glass door is the more affordable option. Because it is easier to manufacture and more common, the initial investment is lower. Polycarbonate is a premium material and carries a higher price tag. For many owners, this extra cost is viewed as an insurance policy. If you are working in heavy woods with a brush cutter, the cost of a polycarbonate door is much lower than the cost of downtime and medical bills resulting from a shattered glass door.
The choice between these two materials should ultimately be based on your specific job site. If your skid steer spends most of its time loading mulch, moving pallets, or clearing driveways, tempered glass will likely provide the best clarity and ease of maintenance for years to come. If your work involves heavy demolition, mulching, or any task where objects are frequently thrown toward the machine, the safety and impact resistance of polycarbonate are well worth the additional investment.
Regardless of which material you choose, a well sealed cab enclosure significantly improves the operator experience. By reducing noise levels and allowing for better climate control, a high quality cab helps prevent operator fatigue and keeps the machine productive in any weather. Regularly inspecting the seals around your glass or polycarbonate panels will ensure that your cab remains a clean and comfortable environment for the long haul.
