Why Replace A Polycarbonate Conservatory Roof with Glass

There are many articles which discuss the modern benefits of a plastic-like material commonly known as polycarbonate. While this substance does offer some cost-saving advantages, the fact of the matter is that tempered glass is often the preferred option in terms of windows and roofing. So, what are some of the reasons why replacing a polycarbonate roof with glass could be a welcome change for your conservatory? Let us take a look at some of the traits associated with glass as well as why it is the preferred solution.

The "Clear" Difference

Visibility is a major concern within any conservatory, and for good reason. The intention is to enjoy as much outside light as possible. Unfortunately, polycarbonate can become cloudy or "foggy" over time; particularly if it is exposed to the harsh ultraviolet rays of the sun. Glass has always provided superior levels of transparency; enabling your conservatory to reflect a clear and crisp appearance.

Glass is Less Susceptible to Heat Damage

There can be times when your conservatory will have to endure a significant amount of solar heat during the warmer months of the year. The good news about glass is that its chemical properties make it highly resilient in regards to thermal damage. This is one of the main reasons why tempered glass is often used during the manufacture of cookware. Polycarbonate may be prone to warping if it is exposed to sunlight for extended periods of time and can become brittle because it does not have UV protection, unlike glass. This ultimately signifies that it will need to be replaced; a time-consuming and costly project.

What About Structural Requirements?

It is a well-known fact that glass is heavier than polycarbonate. While this could be a disadvantage under certain circumstances, the exact opposite is normally true when referring to conservatories. The dense nature of glass tends to provide a greater degree of structural support and stability. However, this may also depend upon the design of the conservatory in question. This is also why it is wise to speak with a professional in order to determine whether structural integrity should play a role when making a decision.

Better Insulation

Most of us have heard of the concept of double-glazed conservatory windows and roofs. This configuration is normally associated with glass due to its rigidity. Two panes of glass will be separated by a small amount of air. Air is an excellent insulator so it will help your conservatory to retain heat. This is particularly relevant when referring to the roof of the structure. If you have been spending a great deal of money on energy bills during the autumn and the winter, the chances are high that polycarbonate materials are to blame.

The Long-Term Edge

While replacing a polycarbonate roof with glass might be slightly more expensive, we need to look at this investment from a long-term point of view. As glass is highly durable and resistant to scratches, there are few maintenance issues and it will last much longer when compared to polycarbonate. This provides you with a higher return on investment (ROI); an important consideration if you have been looking to increase the value of your home.

A Visual Appeal

Finally, let us always remember that traditional glass is a timeless and elegant material to employ. This substance will help to bring out the beauty in your conservatory and its aesthetic appeal cannot be denied. Whether the conservatory has only recently been constructed or if it has existed for decades, glass always represents the most beautiful option.


Glass can also be self-cleaning, whereas polycarbonate lacks this option entirely. Clean glass is beautiful and will allow much more light into your home than polycarbonate roofs would ever manage.
