Which is Better for Roofing – Perspex Acrylic or Polycarbonate?

Is Perspex the Same as Polycarbonate?

At first glance, it may seem like acrylic, branded as Perspex, is the same as polycarbonate. They are widely regarded as supplementary products. There are, however, some notable differences between acrylic and polycarbonate. When it comes to choosing one for roofing, it is important to differentiate between them. Keep reading to learn more about these two products and how they differ from each other.

Perspex vs Polycarbonate: Pros and Cons of Each

Ease of use

The first distinction between polycarbonate and acrylic can be made in terms of workability, more specifically, cutting and drilling. Cutting sheets of acrylic is much easier than cutting polycarbonate, which is much more resistant, even if you are using specialized cutting machinery.

When it comes to drilling, however, polycarbonate is much easier to work with. If you need a product that you can drill without having problems and that is easy to fix leaks in, you will be better off with polycarbonate as acrylic may break or crack more easily.


When it comes to transparency, acrylic is the better option, especially for roofing applications. Both acrylic and polycarbonate are clear, but polycarbonate may start to turn yellow when exposed to the sun.

With age, both acrylic and polycarbonate may start to lose their transparency, but acrylic’s transparency can be restored with the application of polish. When polycarbonate loses its transparency, however, it is permanent.


Both acrylic and polycarbonate can sustain severe levels of hammering and affliction without showing signs of damage or deterioration. Heavy blows to either one of these plastics will seldom cause damage as they are incredibly resilient to a wide range of materials – even metal.

When measured against each other, it is clear that polycarbonate is much stronger than acrylic. This means that if you favour strength above transparency, polycarbonate may be the better option for your roofing needs.


Acrylic is available in a wide range of colours. Polycarbonate, on the other hand, is only available in a select few colours. Also, keep in mind that polycarbonate tends to turn yellow when exposed to sunlight, which makes acrylic the best choice for roofing as far as colours are concerned.

Easy Cleaning

Both acrylic and polycarbonate are easy to clean with the application of non-abrasive materials such as soap and water. Despite the fact that both of these materials are used for bulletproof gear, they can withstand scratches, so it is important to refrain from using abrasive cleaning materials such as hard sponges.

It is also important to avoid using strong chemicals to clean these plastics. Polycarbonate is, to an extent, more resistant to chemicals than acrylic, but substances such as ammonia can cause damage over the long-run.

Although both acrylic and polycarbonate can obtain scratches and yellowing from exposure to the sun, it is important to remember that only acrylic can be treated for these types of damage.


As a rule, polycarbonate can be vastly more expensive than acrylic, which is significant for large roofing projects.


In terms of cost, appearance, and easy treatment of damages, a Perspex roof may be a better option than polycarbonate roofing. However, because of polycarbonate’s resilience and resistance to chemicals, it is better than Perspex as covering or roofing for decks, pools, sheds, and greenhouses. You can also use polycarbonate for patios and garages. Since these areas don’t require large surfaces as a roof or cover, the higher costs are easier to manage.

It is important to only make use of high-quality Perspex roofing to ensure prolonged use and more sufficient protection against the elements and other forms of damage.
