What Are The Benefits Of Polycarbonate Roofs Compared With Glass?


When you build a conservatory, you are faced with a tough dilemma: which material to choose for your conservatory roof.

There are two options on the market, both of which come with their own set of advantages and disadvantages.

The first one is polycarbonate, and the second is glass. But which is the better option? It’s time to find out…

Glass Conservatory Roofs: An Overview

If you conduct a survey among professionals in the business, most of them will tell you that a glass roof is still the best choice on the market.

Glass is the traditional choice when it comes to conservatory roofing-and the only choice for many homeowners. In the conservatory polycarbonate vs glass roofing debate, the classical style of glass often sees it come out on top.

The biggest advantage of a glass roof is its thermal efficiency. Glass helps retain more heat, and keeps you warmer during the chilly winter months.

In the end, that saves you money on energy bills. The second major advantage is that glass is less prone to scratches.

The glass roof is not as noisy as polycarbonate. You will still hear the rain, but not as much as you will do with a polycarbonate roof.


From opting for frosting, to eye-catching effects on the glass, there are many ways that you can customise a glass roof to your preference

Glass Conservatory Roofs: The Options

When you consider either option, there are sub-categories. Here’s a list of the most common glass types available:

-Glass Option 1: Active neutral (grey) that allows 56% light transmission, 68% solar transmission, and has U-Value of 1.0

-Glass Option 2: Active blue that allows 50% light transmission, 67% solar transmission and has U-Value of 1.0

-Glass Option 3: Active sunshade blue that allows 27% light transmission, 80% solar transmission and has U-value of 1.0

There are many ways that you can customise a glass roof; just as there are multiple types of conservatory, there are multiple types of glass roofing styles to choose from.

The options above are particularly popular among property owners, however, you can also go one step further and opt for tints, frosting and additional eye-catching effects to the glass.


From increased longevity, to superior soundproofing properties, a glass roofed conservatory offers a variety of benefits, making it a highly desirable choice

The Benefits of Glass Roofing

Glass also has some excellent benefits, that make a glass conservatory roof a highly desirable choice. Here’s 3 of the primary plus points of choosing this option: 

• Sound Insulation – Compared to polycarbonate, the sound insulation properties of glass roofing are much better. Its still very difficult to completely block out the sound of rain, but it’s certainly lessened with glass roofing.

• High Light Quality – Clear glass is undoubtedly the forerunner when it comes to light quality. A full glass conservatory creates a unique ambiance in the room.

• Long Lifespan – Glass has an excellent lifespan, able to stand up to the pressures of the weather for many years. An important reason why, for some homeowners, glass wins the conservatory polycarbonate vs glass debate hands down.


Although more affordable that glass roofing, a polycarbonate roof does lack the insulation benefits of other roofing alternatives-and will require additional insulation if you wish to enjoy the room year round

Polycarbonate Conservatory Roofs: An Overview

The biggest advantage of a polycarbonate conservatory roof is the price. Comparing the prices between glass and polycarbonate shows that you will pay 3 to 5 times less by going the polycarbonate way.

Since a polycarbonate roof is more affordable, the majority of people plump for that option.

The unfortunate downside is that polycarbonate roofs lack the natural insulation benefits of other roofing alternatives overall.

Polycarbonate Conservatory Roofs: The Options

Polycarbonate is a material made from thin sheets of plastic laid on top of one another. Here are some of the different polycarbonate options:

-Polycarbonate Option 1: Clear polycarbonate that allows for 63% light transmission, 62% solar transmission, and has U-Value of 1.5

-Polycarbonate Option 2: Opal polycarbonate that allows 15% light transmission, 35% solar transmission and has U-value of 1.5

-Polycarbonate Option 3: Bronze polycarbonate that allows 20% light transmission, 23% solar transmission and has U-value of 1.5

-Polycarbonate Option 4: Bronze/opal polycarbonate that allows 10% light transmission, 15% solar transmission, and has U-value of 1.5

-Polycarbonate Option 5: Heat shield/Opal polycarbonate that allows 5% light transmission, 8% solar transmission, and has U-value of 1.5

As you can see, the thermal U-value remains the same, but light and solar transmission change.

You can prioritise either one of those. But the more light you allow, the more heat you get as well.


Despite being made from plastic, which isn't considered to be the strongest of materials, polycarbonate is actually exceptionally strong-and delightfully durable to boot!

The Benefits Of Polycarbonate Roofing

When you imagine a conservatory, you generally imagine glass-which puts polycarbonate at a bit of an initial disadvantage. The unique material, consisting of multiple layers of plastic, is used worldwide for a variety of purposes.

The design of polycarbonate means that it is very lightweight, especially when compared to glass, but still works as a remarkably efficient roofing material.

Polycarbonate roofing may seem like the underdog when looking at which is best, conservatory polycarbonate or glass, but it has an impressive list of very appealing features and benefits including:

 Incredibly Strong – Despite being made from plastic, which isn’t considered to be the strongest of materials, polycarbonate is exceptionally strong, and very durable.

• Affordable – Especially when compared to glass, polycarbonate is a more affordable roofing option for many homeowners. Not only is the construction cost generally lower, but it’s much easier and often quicker to work with polycarbonate.

• Weather Resistant – The composition and design of polycarbonate means that it offers high levels of weather resistance. This extends to low and high temperatures, as well as harsh weather, like rain and snow.


In addition to controlling your temperature, conservatory roof insulation will also help to reduce the drumming noise from rain, and make the room far more cosy to boot!

Conservatory Insulation: Foiling Temperature Fluctuations Forever

Both sides of the conservatory polycarbonate vs glass debate have excellent benefits, giving customers a great variety when it comes to getting a conservatory roof that suits their needs.

For those who love the sound of rain, and want a lower cost roof, polycarbonate is the way to go. While for those that want sound-proofing and a traditional look, glass may be much better suited.

However, neither roofing system is going to create a conservatory that you can enjoy all year-round, without worry over the temperature. The specialist roofing addition that gives conservatories that ability is conservatory insulation.

Why Home Logic System’s the Overall Conservatory Roof Insulation Winner

Regardless of which option you choose, our advice is that you should ALWAYS add insulation.

A conservatory should feel like a relaxing refuge to retreat to; a place where you can dine, talk with friends, listen to music, read a book, or just simply relax.

Without adequate insulation, your conservatory will be sweltering hot in the Summer, and freezing cold in the Winter.

In addition to controlling your temperature, the insulation will also reduce the noise from rain , and make the room far more quiet and cosy.

The option we recommend is Home Logic Lightweight Roof insulation System.

It’s a six layer insulation system that ensures an ambient temperature in your conservatory, all year round. Bliss!
