Upgrade Your Conservatory

  • Kindle the spirit of your conservatory again by upgrading it. With a revamp that keeps your conservatory an all-season space, you’ll no longer have to endure a freezing cold room in the winter and a sweltering suntrap in the summer.


    For a comfortable conservatory it’s important to regulate the temperature of the space. Luckily, at Crown Commercial Windows there are a few options available to you. Upgrade your windows with double or triple glazing, or keep the heat in with tiled roofing. You might even want to consider replacing your windows and doors entirely to prevent chilly draughts. 


    If your conservatory is old or has a few issues, think about a full upgrade and make the most of what our practical solutions can do to bring your conservatory back to life. After all, you’ve invested in the space, so you’ll want to make sure you’re able to use it as much as possible. To make your conservatory more projectly we can install lights for the evenings or make your windows a little tinted to prevent squinting on brighter days.

  • Upgrade your existing conservatory with a range of modern and traditional styles and colours – newly built or using your existing foundations and walls. Consider installing new performance glass panels that are better insulated and will boost your project’s energy efficiency. You could also choose a solid tiled roof to your conservatory’s pre-existing frame. Even making small tweaks can have a big impact – like adding new bi-folding doors out to your garden.

Common Questions

What are the best ways to upgrade my conservatory?

There are plenty of ways you can freshen up your conservatory by upgrading its components. To start, note what issues your conservatory has. Is it too hot or too cold? Do you feel draughts? Are the fixings on your windows in need of a replacement? Are UV rays wearing your furnishings down? Is your conservatory roof getting grubby? All of these are common issues seen by our team. Make a list, get in touch, and we’ll be able to advise you on the best way to upgrade your conservatory.

How can I upgrade my conservatory to make it more insulated?

You can reduce heat loss in several different ways. Old polycarbonate roofing has especially poor insulative properties, so we can replace this with a tiled roof, double glazed glass roof, or lantern roof — whichever design you prefer. We can also change single glazed windows to double or triple glazing to improve heat retention and reduce the cost of your energy bills. To discuss conservatory insulation in more detail, contact us today to chat to one of our friendly experts.

When should I upgrade my conservatory?

In 2006 alone, around 210,000 conservatories were installed. Unfortunately, most of these were substandard in their insulative properties. Many old conservatories don’t perform to a standard you’d expect or want in your project. If you’ve had yours for a while or if it was already installed when you bought your property, it might be time to think about getting a replacement (especially if it is made of old aluminium). Older uPVC conservatories can also experience issues but are easily upgraded by installing new windows and doors. If you’re noticing poor heat retention and draughts in your conservatory, these are also key indicators that an upgrade is needed.

How can I upgrade my conservatory to make it match my project?

Since construction materials have experienced many new advancements, upgrading conservatories has become progressively easier. We can take the design of your current project and make sure we upgrade your conservatory in line with your existing aesthetic. This is possible due to the fantastic range of uPVC finishes available to us.

For those who are interested in a conservatory upgrade involving tiled roofing, we will aim to match the tiles used to the ones already on your house. As for pillars and dwarf walls, we’ll do our best to find complementary brick or paintwork as well. Contact us today to discuss all the ways that we can make your project and conservatory work together.

As a local company we are proud to offer British Standards BS7412/PAS24 for enhanced security.

We refuse to compromise on quality

Our windows are made from British Made, high quality MarinespecTM components, with up to 25 years anti corrosion. They are built specifically for the more exposed areas of corrosion, such as coastal environments to give you worry free performance beyond your guarantee.  We believe spending more on components is worth every penny, and sets us apart from our competitors.

State of the art fabrication for best quality

We have invested millions of pounds into one of the most state of the art manufacturing facilities in the UK.  This enables us to provide you with consistently high quality products at exceptionally good prices. Our loyal factory workers are well trained and take pride in their work, they really care about quality.  Our machines are maintained according to a rigorous servicing regime to keep them in top condition.

Superior energy efficiency

Our ‘A’ rated energy efficient and triple glazed windows are tested by the BFRC, which will save you money on your heating bills. By law your windows and doors have to meet strict thermal performance regulations but you can be rest assured that our products exceed current requirements.

Energy saving is incredibly important and so is keeping your fuel bills down. We are continuously looking for ways to make our projects energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your project warmer, they will reduce your energy loss.

Don’t just take our word for it!

Our suppliers conform to strictly controlled and independently monitored Quality Management Systems such as ISO 9001, to ensure that everything is done correctly and according to best practise.

Our windows are tested independently by British Standards for security, weather tightness and strength performance. This means that periodically, we have to send them to independent test houses, in order to be tested to destruction.

These are just some of the many standards the products in our vast range conform to. Needless to say we take the quality of our products very seriously indeed.
