Polycarbonate Pros And Cons: The Essential Guide

polycarbonate pros and cons

A conservatory is a welcome addition to any home; particularly if you have a smaller property, and would like some extra space, or if you have a beautiful garden or outdoor environment to enjoy.

However, such charm comes at a cost; it’s not cheap to have a conservatory built, or for any part of it to be modified or replaced. Conservatory owners frequently find that their clever addition gets too hot or too cold and start shopping around and researching into roof replacements.

Polycarbonate roofs are the most common of conservatories but it’s important to know whether or not it’s right for your conservatory before you invest.

With this in mind, we delve into the details of polycarbonate as a product, exploring what it is, how it works, and the pros and cons of opting for this roof choice. Let’s begin!

Polycarbonate Roofing 101: What’s It all About?

The right roofing material can make all the difference between a space that is the perfect peaceful retreat, and one that will need constant maintenance.

Polycarbonate is an incredibly diverse material, used all over the world for a vast range of purposes, from riot shield to baby bottles. It’s unique properties also make it a highly popular roofing choice for patios, porches, and conservatories.

Commonly pitted against the more traditional glass roofing, polycarbonate roofing can be seen on conservatories all over the UK. 

The product consists of multiple sheets of the thermoplastic layered together to create a panel. These can then be inserted into a conservatory roof system to create a strong finish that performs very well in practice.

There are different grades of polycarbonate, and different finishes, such as clear or opaque, making polycarbonate a customisable roofing choice, that still allows natural light to filter into an area.

Polycarbonate Pros


Polycarbonate conservatory roof replacements are considerably cheaper than glass equivalents, making them a cost-effective solution for most: and often the decision is made solely on this basis.


There is a cheaper option! Home Logic Conservatory Insulation is up to 50% cheaper than having a polycarbonate conservatory roof replacement fitted.

Home Logic Conservatory Insulation will also continue to save you money during its use, as the insulation will ensure you require less heating and cooling of the room, and therefore lower your household energy bills in the process.

There should be no need for your conservatory roof to withstand real force! You should find that whatever your roof replacement solution, it is strong enough to keep your conservatory safe and secure, as well as at a comfortable temperature.

This is why Home Logic Conservatory Insulation makes a suitable conservatory roof replacement alternative: it regulates temperature, and also offers significant, structural support, so it’s marvellously multi-functional.

polycarbonate pros and cons

Whether or not your conservatory will require external admin and a due legal process depends on your local building authority. You need to contact them in advance of any work being carried out, and may have to delay your building work to allow time for their processes and, ultimately, permissions

Polycarbonate Cons

Planning Permission:

When you convert your conservatory roof, the percentage of it which becomes either translucent, opaque or non-glass can justify requiring planning permission from your local authority, as technically it can change the legal classification of the room/structure.

Whether or not your conservatory will require external admin and a due legal process depends on your local building authority. You need to contact them in advance of any work being carried out, and may have to delay your building work to allow time for their processes and, ultimately, permissions.


There is another way! Home Logic Conservatory Insulation is applied directly onto your existing roof on the interior of your conservatory, and then covered.

As there’s no external construction work, no local building authorities require any administration, processes or permissions to be completed.

The installation of Home Logic Conservatory Insulation as a conservatory roof replacement also means you don’t have to facilitate a team of builders in your home, either.

Instead, the product is fitted by specialist BBA (British Board of Agrement) accredited expert technicians, who specialise in conservatory insulation.

The work can be carried out within a few hours, rather than days, and by a team of just two tradespeople in total.

As a result, the disruption to usage of your conservatory will be minimal… so you can get back to enjoying the outdoors indoors again as soon as possible!


Polycarbonate conservatory roof replacements unfortunately do not block out sound from the outside world effectively.

The nature of the plastic material, combined with its lack of density means that noise from outdoors can easily penetrate through, and be audible within your conservatory.

If you live in a busy, urban area, this isn’t ideal for a living space that’s normally intended to be quiet and relaxing!


Home Logic Conservatory Insulation can effectively soundproof your conservatory roof, and keep disturbances at bay.

The nature of the product – a layered multi-foil insulation material that has air pockets incorporated within its structure – means that sound is absorbed by your roof’s covering, and is unable to pass through into the room.

Having Home Logic Conservatory Insulation installed can greatly lower noise levels and ensure your conservatory stays peaceful so even if you want to nap, you can do so in peace.

The Question On Everyone’s Lips: Longevity

A combination of all the benefits of polycarbonate mean that it has a fairly impressive lifespan. Normally, the answer to, how long does polycarbonate roofing last, would be between 10 and 15 years.

However, this can extend to around 25 years with the right maintenance, and a high-quality product.

Of the maintenance required to keep a polycarbonate roof in excellent condition, and protect your conservatory as whole, conservatory insulation is essential. For a conservatory that you can use all year-round, in any weather, insulation is your key to success.

The Future of Your Conservatory: The Long-Term Aim

Conservatories are a great way to add value to your home, up to around 10%, but only if they are built to last, and a usable space. Today, it’s insulation that makes a conservatory a truly appealing space – banishing cold winters and blistering hot summers.

To continue the longevity of a strong and stable conservatory roof, multi-foil conservatory insulation is the way to go, giving you the best benefits and a lifespan that will ensure your conservatory is going to keep you toasty warm in the winter, and nice and cool in the summer, for years to come.

Multi-foil insulation is a form of blanket insulation, where multiple layers of different insulation material are installed together, for optimum heat regulation. Contained behind a stunning conservatory roof covering, it bolsters the appearance of the conservatory roof, whilst introducing heat and sound insulation.

Polycarbonate Roofing and Multi-Foil Insulation: Like Peas In A Pod

Multi-foil insulation can work perfectly with polycarbonate roofing to provide a strong roof with fantastic insulation properties. The insulation is also very well suited to glass roofing, providing a much better alternative to keeping a conservatory warm, than replacing the entire conservatory.
