Fabric roofs vs polycarbonate roofs: what are the pros and cons?

Posted by Admin

Schools, hospitals, leisure centres and commercial businesses often install canopies as a cost-effective way to create extra space.

But the type of roof you choose for your canopy will depend on how you plan to use the new area.

Polycarbonate Roofs

Polycarbonate roofs are fitted to aluminium and timber-framed canopies of all shapes and sizes used as walkways, dining rooms, storage, entrances or outdoor play areas.

The canopy modular design means they are perfect for awkward or hard-to-reach spaces, such as courtyards and are easily tailored to meet your specific needs.

Plenty of light

Opal polycarbonate is our most popular choice for canopy roofs. It has a milky appearance to prevent solar glare but still allows plenty of light to come into the canopy.

Protection from the sun

The panels have a double UV-protective coating which blocks 98 per cent of all the most harmful UVA and UVB rays, making it ideal for multiple uses in various settings such as schools and hospitals.

Rainproof

A polycarbonate roof will keep you dry, however heavy the rain is, allowing you to use the canopy in all weather conditions and throughout the year.

Minimal maintenance

A polycarbonate roof needs minimal maintenance. You will need to remove any debris, like leaves or mould and mildew, as well as bird mess from the roof, just like with any other structure.

But the panels are very easy to clean with a soft brush and an eco-friendly detergent.

Produce your own energy

One of the biggest bonuses of our polycarbonate roofs is that they are strong enough to take solar panels.

So, they can be added at the time or retrofitted when budgets allow, helping you to reach your carbon-neutral journey and slash energy bills.

Fabric Roofs

Our fabric sail shades are often a talking point in schools and businesses because they come in various vibrant colours and striking designs.

They are ideal for small areas over a playground or in an outside space in a restaurant or rest area at a business, transforming a previously unused or underused area into an enticing area to sit in.

Making a statement

The wide variety of bright colours and shapes allows you to choose a design and colour personal to you.

You can opt for one or several shades to create an original and striking new area for customers, students or staff or choose colours that match and reinforce your branding.

Designs include triangular, square or rectangular shapes with posts in each corner; conic or umbrella sails suitable to cover large areas where the number of posts has to be kept to a minimum with a single supporting mast.

Finally, perimeter shade sails are often used in areas where it’s only possible to dig small foundations. They are supported by a steel framework underneath the fabric helping to put less tension on the posts.

Protection from the sun

Like polycarbonate roofs, fabric roofs provide you with 98 per cent UV protection.

However, the fabric doesn’t allow light to shine through to the area directly below, though plenty of light enters from the sides.

Not fully rain-resistant

If you want to use your sail shade in colder, wetter weather make sure you ask for the fabric to be waterproofed.

Also bear in mind not all areas underneath can be kept dry when it rains because of the design, which may make a shade sail less useful in colder months.

Low maintenance

While our steel frames are very low maintenance and will last for many years, you will need to look after the fabric panels to keep them in tip-top condition.

You can do this by cleaning any debris that collects there to stop sagging or damage. In extreme weather, you may need to remove them.

Extensive Groundworks

You will need more extensive groundworks for a sail shade than a polycarbonate roof canopy because they need larger foundations to make sure the posts are secured rigidly.

What is the main difference between fabric and polycarbonate canopy roofs?

 Polycarbonate roofs are rigid, fully weatherproof and allow diffused light through, making them suitable for year-round use in all weather. Fabric roofs, or shade sails, are more visually striking and come in a wider variety of colours and shapes but do not allow light to pass through directly and are not always fully waterproof without a special treatment.  

 

Do both roof types protect against UV rays?

Yes. Both polycarbonate and fabric roofs provide 98 per cent UV protection, blocking the most harmful UVA and UVB rays. However, polycarbonate panels achieve this while still allowing a good level of light into the space beneath.  

 

Can solar panels be added to a polycarbonate canopy roof?

Yes. Polycarbonate roofs are strong enough to support solar panels, which can be fitted at the time of installation or retrofitted when budgets allow. This makes them a practical option for schools or businesses looking to generate their own renewable energy and reduce running costs.

 

Are fabric shade sails suitable for use in wet weather?

Fabric shade sails can be waterproofed on request, but their design means it is not always possible to keep the entire area beneath them dry in heavy rain. They are best suited to drier seasons or as a complement to a polycarbonate canopy that can be used all year round.  

 

Which canopy roof type requires more groundworks?

Fabric shade sails require more extensive groundworks than polycarbonate canopies because they need larger foundations to ensure the posts are rigidly secured against the tension of the fabric. Polycarbonate canopies on modular aluminium frames are generally easier to install, including in awkward or hard-to-reach spaces such as courtyards.

 

Can fabric shade sails be used in commercial or hospitality settings as well as schools?

Yes. Shade sails are widely used in restaurants, cafes and rest areas in commercial settings where their vibrant colours and striking shapes can transform an underused outdoor space into an attractive area for customers or staff. They can be designed in colours that match or complement existing branding, making them a flexible and eye-catching addition to any outdoor environment.
