Polycarbonate or Glass for Side Infill Panels
When enclosing a veranda, the choice between polycarbonate and glass for side infill panels is critical to both the visual impact and the long-term utility of the area. We compare these materials on their physical properties, durability, and how they contribute to the comfort of your outdoor space.
Properties of Polycarbonate
Polycarbonate is a durable, lightweight plastic. It is highly impact-resistant, making it a safe choice in areas with high activity. It typically comes as a multi-wall or solid sheet and can be easier to install in complex configurations. However, it can scratch over time and may lose some clarity compared to glass.
Properties of Glass
Glass panels offer superior visibility and a premium look. Toughened glass is very strong and provides excellent light transmission. It remains clear throughout its lifespan and is resistant to scratching. It is significantly heavier than polycarbonate, requiring robust framing to support the panel weight.
Technical Comparison Factors
We look at these criteria when helping you specify.
- Clarity and visibility
- Weight and structural requirements
- Scratch and impact resistance
- Cleaning and long-term appearance
Environmental Considerations
Polycarbonate can be prone to yellowing if not protected by a high-quality UV coating. Glass is naturally inert and unaffected by solar UV exposure, making it the more stable choice for longevity.
Common questions
Which material is better for privacy?
Both can be specified with tints or frosted finishes to achieve privacy, though glass usually maintains a higher clarity if you want an unobstructed view.
Is polycarbonate cheaper than glass?
It can be, depending on the thickness and the specific grade. However, the cost of the supporting frame for glass must also be considered.
Does polycarbonate scratch easily?
Yes, it is more susceptible to surface scratches than toughened glass, which is why we recommend careful cleaning methods.
Which lasts longer?
Glass has a longer lifespan in terms of clarity and resistance to environmental degradation.
Design and Visual Impact
If your garden view is the main reason for your project, glass is almost always the preferred choice. For high-impact areas, like children's play zones, polycarbonate’s resilience can be the deciding factor.
In short
Glass offers superior clarity and longevity; polycarbonate provides impact resistance — choose based on your visibility priority and site use.
