Upgrade Your Conservatory

  • Transform your conservatory into a living space you can use all year round. Our conservatory upgrades are designed to be functional and beautiful for a fraction of the cost of replacing your entire structure.

    From the smallest tweak to a full upgrade, our practical and modern solutions will turn your draughty old conservatory into a fully insulated space that you can use throughout the year. 

    Whether you own a classic Victorian conservatory or a more contemporary style, we can help you integrate your conservatory into your year round living space. We use the highest quality materials and your upgraded glazing or roof will be bespoke manufactured in our state of the art South West facility. Each product then undergoes extreme weather testing so you can be comfortable in the knowledge your conservatory will continue to provide enjoyment for years to come.

    From smart lighting to tinted window films, double or triple glazing to a fully tiled roof, our conservatory upgrades will ensure your conservatory is better insulated and more energy efficient in the depths of winter and cooler in the height of summer. The result is a truly beautiful and usable space at a fraction of the cost of a new conservatory or extension.

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?

To decide on the best upgrades for your conservatory, think about the issues you have. If your conservatory is freezing cold in winter and sweltering in summer you might want to retrofit a tiled roof. If your conservatory isn’t performing efficiently because the seals on the windows have failed then opt for new triple or double glazing

If your conservatory roof is dirty and stained because it’s difficult to maintain, then consider a replacement with self cleaning glass. If you’re fed up with faded furnishings then we can fix that with UV resistant glass. Whatever the issue, at Otter Windows we have a solution, so contact us to discuss the best upgrades for your conservatory.

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

One of the best ways to add insulation to your conservatory is with a tiled roof which reduces heat loss from the moment it’s installed. If you prefer a glass roof, choose a replacement with a U-rating as low as 0.8 to keep you cosy through the winter. 

Another major culprit of heat loss in your conservatory are single glazed windows. An upgrade to double or even triple glazing will transform your conservatory into a space that’s usable all year round

When should I upgrade my conservatory?

If your conservatory is less energy efficient than it used to be then it could be time for an upgrade. Although it’s probably too late to rescue an old aluminium framed structure, there are plenty of upgrades you can make to your uPVC conservatory to make it a usable space all year round.

Replacing your roof, upgrading your double glazing or fitting next generation glass are all easy ways to bring your conservatory into the 21st century.

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

If you want to retrofit your conservatory to look as if it was built at the same time as your property, you can. At Otter Windows, we use the latest technologies and techniques to ensure that your conservatory integrates seamlessly with your home whether that’s with a tiled roof or the addition of dwarf walls and brick pillars that match your existing walls. We can also match your existing window and door finishes for an effortlessly streamlined look, so contact us today to find out more.

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.
