Was your conservatory built pre-2011? If so, there is a very high chance that it will have a polycarbonate roof on it.

Polycarbonate roofing sheets are used for conservatory roofs because they are a strong thermoplastic material. Polycarbonate is also cheap to produce, lightweight and clear so over the years, it has become a common choice for conservatory installation companies to offer as a roofing option for customers.

Warm Conservatory Green Space

There are, however, many drawbacks that come with a polycarbonate roof. The average lifespan is between 10 to 15 years. By comparison, Green Space UK guarantees our panels for a full 10 years and they generally last much longer too.

Alongside the short lifespan, the problem with a polycarbonate roof is that it provides very little heat or sound insulation. In heavy rain or hail, your conservatory will be incredibly noisy. High winds will also cause issues with sound as the polycarbonate provides little to no sound dampening. 

In the summer your conservatory roof will let in and then trap heat. That can make it hotter than a greenhouse. Plus the extra heat can seep into the rest of your home, meaning the entire house is too hot. 

In winter you will have the exact opposite problem. Because a polycarbonate roof has almost no insulating properties, your conservatory will likely be the same temperature as the outside. You can install radiators or use portable heaters but this will significantly increase electricity or gas costs as the heat generated will quickly escape through the uninsulated roof. 

You can retrofit a polycarbonate roof with extra insulation to help keep a conservatory warmer in winter and cooler in summer, but that will not address any leaks, the short lifespan or the look of the roof.

The final issue with a polycarbonate conservatory roof is not always apparent until a few years after it has been installed. These roofs are often very difficult to maintain. The material scratches easily which can leave an ugly mark. Plus, once the polycarbonate roof has been out in the elements for a few years, it may start to discolour. That makes your home look older and less well maintained. Worse still, algae can actually begin to grow within the polycarbonate conservatory roof, making it look green and ugly.

The reason so many conservatories were built with Polycarbonate roofs is that the material is generally the cheapest option. In traditional polycarbonate roofs, the most common thickness used are 16mm, 25mm and 35mm. This made the panels light and cheap so they were easy to make and quick to install. 

If your conservatory currently has an old polycarbonate roof insulation in it, the chances are there are only a few months of the year where you will be able to comfortably use your conservatory as a living space and not a storeroom or dumping ground.

How Do Thermotec Roof Panels Work?
