Upgrade Your Conservatory

  • If your conservatory is looking tired, is too hot in the summer, or too cold in the winter, Kayvex can help. We can offer you a conservatory upgrade, for better energy efficiency and to add modern features.

    Conservatories can become less energy efficient over time, so if you’re having trouble regulating the temperature in your conservatory, there are options for improvements. We can take out your single glazing and add double, or even triple glazing, which keeps the space warm in winter and cool in summer. You can also add a tiled roof, which is a sure-fire way to help with insulation.

    Kayvex can also give you a full upgrade with modern features that make an older conservatory look brand new. Adding new lighting around the edges of the structure can make your conservatory a nice place to sit at night, or if you get too much bright sunlight at certain times of day, then adding tints to your window can help.

    We build and upgrade conservatories in a wide range of styles, from sleek, contemporary looks, to classic Victorian and Edwardian style structures. Our team are experts on conservatories, so if you’re thinking of a conservatory upgrade, we can give you advice on what can be done with the current building. If parts need to be manufactured, we can make them in our UK-based factory, so you get the perfect finish.

  • 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 home’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?

Each conservatory is different, and so you’ll need different techniques to make your conservatory feel new again. First, identify the issues your conservatory has; have you noticed draughts or cold spots? Are your window fixings old and rattling? Are your furnishings pale and faded from exposure to the sun’s UV rays? Perhaps your roof is dirty and stained, or you simply want better insulation to be able to enjoy your conservatory all year round. If you have one, or all, of these issues, then contact us today and we can find the best way to upgrade your conservatory.

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

Making a conservatory more insulated is what we do best at Kayvex. We can replace your old roof for a thermally efficient glass one, or a tiled roof for ultimate heat retention. If your conservatory has single glazing, then we can fit double or triple glazing instead which will make a huge difference to heat retention, as well as reducing the amount of condensation you’ll find on the windows in the morning!

When should I upgrade my conservatory?

If you don’t think your conservatory is performing at its best, you’re not alone. Over 200,000 conservatories were installed in UK in 2006, and none of them are anywhere close to the standard levels of insulation today. These substandard conservatories are freezing in winter and sweltering in summer; simply put, they don’t perform well enough to be a useable extension to your home. Unless you have an extremely old aluminium frame, it’s not necessary to completely replace your conservatory; we can fit double or triple glazing into existing uPVC frames, or put a tiled roof on your existing conservatory for increased insulation. Contact us today to find out more about how you can upgrade your conservatory.

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

We want your conservatory to look – and feel – like an integral part of your home, and modern technology has made that easier than ever. If you want to upgrade to a tiled roof, then we can match our lightweight tiles to those of your home. Or, if you want your conservatory to match the frame style of your windows, our wide variety of colours and finishes can make that easier than ever. 


For orangeries or conservatories with dwarf walls, we’ll do our best to match the brickwork with that of your existing house, so that your extension looks like it was always meant to be there.

Features and benefits

Guarantees you can depend on.

We have built up a great reputation over years of delivering a first class service and excellent products, all from our local, no nonsense all-about-you company.

From characteristic country cottages to contemporary town houses, we’re confident that our products will offer a style and finish to truly transform your home. Through constant innovation the quality, durability and security of our products is genuinely second to none. 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 homes energy efficient and one way is to choose new PVCu windows and doors. Not only will they help to keep your home 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.

The styles available are endless and the choices to suit your home are bigger than ever before. Traditional, contemporary or modern; our versatile window and door designs will create the look you want to complement and enhance your home.
