Polycarbonate vs Glass - Which is Better?

You may not have realised it, but you encounter polycarbonate glazing and panels on an almost daily basis. This incredibly durable and versatile plastic is used as a substitute for glass in a wide range of situations and places - but the two materials look practically identical. 
In this latest blog from The Plastic People, we are going to take an in-depth look at polycarbonate and glass, discuss their similarities and differences; and, ultimately, decide which material is best! (Hint: The answer is obviously polycarbonate!)
On our site, you can find dozens of exclusive guides on home design and improvements, plastic materials and more! If you are still in need of more advice on anything plastic-related, please contact our team at 
What is Polycarbonate? 
Technically, there is more than one type of polycarbonate, as the name refers to a group of thermoplastics (available at several different grades), which contain carbonate groups (hence the name).

Though polycarbonate is particularly tough plastic, it has a wide range of uses in the engineering world as it can be easily moulded and shaped. 
Some applications of Polycarbonate include:
  • Construction materials (roofing and glazing, for example)
  • Data storage (CDs & DVDs)
  • Security components (bulletproof ‘glass’)
  • Windscreens for cars and aircraft 
Polycarbonate vs Glass
Polycarbonate has several perks that allow the material to outperform glass in several scenarios. For starters, polycarbonate is crystal clear - just like glass - and so can be used as a glass replacement whenever a see-through material is desired.
As we have already discussed, it has an incredibly resilient material and is typically 250 times stronger than glass. Polycarbonate is also shatter- and scratch-proof, making it perfect for roofing and window glazing. Moreover, it is actually lighter than glass too!
Another main benefit of polycarbonate is its workability. The material can be easily formed and reformed into complex and intricate designs. This is incredibly beneficial as it allows us to create bespoke polycarbonate glazing for people’s homes and greenhouses. 
Polycarbonate’s workability and shatter resistance also allow us to machine the plastic, trimming it to any desired shape or size. Additionally, we can easily drill holes, and other contact points, into polycarbonate panels - allowing it to be used in even more scenarios! 
Using Polycarbonate in your Home
There are several instances in which polycarbonate can be considered a more efficient material than glass in your home. Here are just a few:
  • Polycarbonate Greenhouse Glazing: This plastic is ideal for creating greenhouses. Not only is it incredibly strong and shatterproof (saving you money on future replacement panels), but it also offers unparalleled heat resistance. We cut polycarbonate glazing panels to any size or shape. 
  • Polycarbonate Roofing: Roofing is one of the most common uses for polycarbonate - also known as twinwall and multiwall in this scenario. Polycarbonate roofing is available in several colours and typically used for summer houses, conservatories and patio covers. This material is also treated with UV resistant chemicals, protecting you and your family from the sun’s rays. 
  • Protective Screens: We have already mentioned that some agencies used polycarbonate to act as bulletproof ‘glass’, but in the last year, as COVID-19 has begun to spread across the globe, more and more customers have come to us requesting polycarbonate sneeze screens and guards. These panels act as physical barriers to stop the spread of pathogens.
  • Vehicle Windows: In this category, we are including everything from car and aircraft windscreens to boat windows. As polycarbonate is so easy to shape and form, it can be made to fit almost any specification. Therefore, we have previously manufactured polycarbonate windows for racing cars, fire engines, recovery vehicles and more. 
Installing Polycarbonate in your Home 
We consider polycarbonate to be a DIY-ready material. This means that - whatever your skill level - you can work with polycarbonate and install it in your home!

Thankfully, we do most of the hard work for you and cut all our plastic panels to size/shape, so all you have to do is slot them into place. 
If you need to join two or more polycarbonate panels (for example, when making a patio cover), you have a couple of options. Firstly, you can easily glue multiple pieces together using an epoxide resin (regular solvents may not hold together). 
Alternatively, for a stronger bond, we recommend fusing panels with methylene chloride. (Note: This is a toxic chemical, so only use in a well-ventilated area). Always leave your panels to bond for at least 48 hours before moving/installing. 
As always, if you need further help with any of the things mentioned in this blog (or anything else plastic-related), do not hesitate to contact our customer services and advice team. They can be emailed at 
We hope you are now all on board the polycarbonate train and will be ditching glass from now on in your home DIY and improvement projects.

Secondary glazing adds an additional layer of protection for you and your home by placing an insulation barrier between your home and the window. By adding this extra layer, secondary glazing keeps the inner panel warmer and reduces condensation formation.
