Having a conservatory can be a great way to extend the space available in your property and also give a new dynamic to the home – connecting you to your outside space. Uses for conservatories vary from home to home, but one issue almost everyone has is the difficulty of changing temperatures due to a lack of good insulation. Maintaining and upgrading conservatory windows is vital when making sure that you get the best comfort, aesthetics, and energy efficiency from your space. If you’re thinking about replacing, covering, or resealing your conservatory windows, this guide will help you with practical information to make the most of your space.
Can I replace conservatory windows with panels?
One option for replacement conservatory windows is upgrading them to insulated roof panels. Unlike traditional glazing, which can often lead to excessive temperature changes, panels are designed to regulate temperatures, improve energy efficiency and make the conservatory usable year-round in different weather conditions.
Benefits and considerations
Replacing existing conservatory windows with insulated panels can offer several benefits, particularly in terms of temperature regulation. Panels are generally better at reducing heat loss compared to glass, making it easier to maintain a comfortable temperature without cranking up the heating. They can also block some of the intense sunlight in summer, preventing the conservatory from becoming too hot.
However, this approach may impact the view out of the top of the conservatories, so if retaining a clear view through the roof and maximising natural light is a priority, look into a solution that allows for insulation without fully covering all of the windows. CosyPanels offers a range of options that allow homeowners to maintain the openness of their conservatory while adding a layer of insulation. Read more about the warm roof options in the CosyPanels’ blog.
Types of panels to consider
When choosing insulated panels, look for those specifically designed for conservatory use. Aluminium or uPVC window frames are commonly used, as they are both lightweight and durable. Thermal panels come in various finishes and colours, which can allow you to personalise the look and feel of your conservatory.
Panels like those offered by CosyPanels® provide much higher levels of insulation than glass or polycarbonate. With up to 50mm of high-density foam insulation inside, they are significantly better than your existing conservatory roof at keeping the heat in.
How to cover conservatory windows
Covering conservatory windows is a popular way to add privacy, control light, and improve insulation. Window coverings come in a wide variety – from traditional blinds suited to older conservatories to more modern conservatory window options like shutters and tinted window films. The key is to find something that balances the look and function of the covering with the overall appearance of your existing conservatory while working within your budget.
The best blinds for conservatory windows
Blinds are an adaptable and efficient way to cover conservatory windows and breathe new life into your space. They come in various styles and materials, each with pros and cons worth considering for a seamless design:
- Venetian blinds: Offering good control over natural light and privacy, Venetian blinds are easy to adjust and available in different materials, such as wood, aluminium, and PVC.
- Vertical blinds: Ideal for larger conservatories, vertical blinds provide good coverage and light control. They’re especially useful for tall windows and can be adjusted to provide UV protection and reduce glare.
- Pleated blinds: These soft fabric blinds create a refreshed look with a cosy feel and are often made with thermal backing, providing some insulation as well as style.
For those interested in eco-friendly or sustainable conservatory blinds, sites like Blinds2Go offer various options that can help with energy saving.
Other conservatory window covering ideas (Curtains, Shutters)
Curtains are another option to consider, especially thermal curtains that can help block out drafts and add warmth during colder months. Floor-length curtains give a traditional, homely touch, although they may take up more space and need more regular cleaning than blinds.
Shutters are another popular option for conservatory windows, adding a classic look while also offering excellent light and privacy control. Made-to-measure shutters are available from suppliers such as The Shutter Store and come in various materials suitable for newer and older conservatories, such as PVC, which withstands humidity and sunlight exposure well.
How much does it cost to replace conservatory windows?
The cost of replacement conservatory windows depends on different factors ,such as the type of glass, frame material, and the size of the conservatory. It’s always important to get multiple quotes to compare prices and ensure you’re getting good value.
Factors affecting replacement conservatory window costs
Several elements impact the overall cost to replace your windows, including:
When it comes to selecting the frame material for your conservatory, the choice between aluminium and uPVC is a big factor in determining the overall cost. Aluminium frames tend to be more expensive than uPVC frames, primarily due to their better durability and long-lasting performance. While uPVC windows are a more cost-effective option, they may not offer the same level of strength or resistance to the elements as aluminium. Aluminium, being a sturdier material, is more resistant to corrosion and wear, making it a better choice for those who want a conservatory that will stand the test of time, even in harsher climates.
The type of glazing used in the conservatory also plays a key role in its insulation and overall cost. Older conservatories often have single glazing, which can be more cost-effective, however there are other options to consider. Double or triple glazed glass is often chosen for its insulation properties, offering a more energy-efficient option compared to single glazed glass. These types of glass offer better energy efficiency by reducing heat loss and helping maintain a comfortable temperature inside the conservatory. Not only that, but double or triple glazed glass can greatly improve the conservatory’s thermal performance. However, these types of glass do come at a higher price than single glazing. The added cost of the more advanced glazing types can be an important consideration, especially if thermal performance or reduced energy bills are a priority for the homeowner.
The size and design of the conservatory are other key factors that affect the overall cost of replacement. A larger conservatory with custom window shapes or unique designs will typically cost more to replace than a standard, smaller conservatory. Customisation often requires additional materials, labour, and specialised designs, which can drive up the cost. The larger the existing space, the more expensive the replacement will be due to the increased materials and work required to fit the new conservatory structure. Homeowners looking to upgrade to a more expansive or intricately designed conservatory should be prepared for a higher cost compared to a simple, more straightforward design. Additionally, older conservatories may require additional work to create a seamless design, especially if you’re adding more modern elements.
For example, replacing all glass windows in a small conservatory with basic uPVC window frames and single glazing might cost around £3,000, while the cost to replace high-quality aluminium frames with triple glazing could be upwards of £8,000.
Example costs for conservatory window replacement
There are many factors involved in costing up window replacement: number of windows, type, glass quality, access, locks, etc, so it can be hard to provide a standard figure. Here are some estimated costs for entire conservatory window replacement:
To replace uPVC double glazed panels
£300 – £500 per window.
To replace aluminium double glazing panels:
£600 – £800 per window.
To replace triple glazing options:
Add an extra 10-20% to the double-glazed prices.
Further to this, Checkatrade estimates that you pay an average of £500 a day for two double glazing installers to fit the windows.

How to reseal conservatory windows
Conservatories require regular maintenance, especially older conservatories. Over time, conservatory windows may develop drafts or even leaks due to ageing seals. Resealing your windows can help keep the space comfortable by stopping cold air from entering and warm air from escaping.
Step-by-step guide for resealing:
- Clean the area: Begin by cleaning the area around the existing seals to ensure the new sealant sticks properly.
- Remove old sealant: Using a utility knife, carefully remove the old, damaged sealant from around the window frames. Be careful to avoid scratching or damaging the frame or glass.
- Apply new sealant: Choose a high-quality, weatherproof sealant suitable for conservatories. Apply it evenly along the frame, filling any gaps for a tight seal.
- Smooth the sealant: With a damp cloth or tool, smooth the sealant for a clean finish and allow it to dry as per the manufacturer’s instructions.
For a more detailed guide on resealing, see CosyPanels’ article on preventing condensation and drafts (how to stop condensation).
Common issues to watch out for
While resealing is a straightforward DIY task, there are common problems to be aware of, such as incorrectly applied sealant or using a sealant that isn’t weatherproof. Both issues can cause water to seep in or drafts to return, making it essential to use quality materials and follow instructions carefully.
Roof insulation may be the best option for energy efficiency
While replacing or covering existing conservatory windows can improve the space’s comfort and energy efficiency, insulating the roof will provide the most significant impact. Conservatory roofs account for a large portion of heat loss, so by insulating the roof, you will retain warmth more effectively than by only addressing the windows.
CosyPanels offers a great range of conservatory insulation solutions, helping homeowners achieve a comfortable, usable space without needing a full conservatory replacement or losing the garden view (explore CosyPanels case studies.)
In the end, whether you opt for window replacement, covering options, or a conservatory roof upgrade, each approach can help improve your existing conservatory’s usability. Keep in mind the balance between looks, comfort, and budget to create a space that suits your personal preferences and style. By understanding your upgrade options, you can enjoy a year-round conservatory that truly complements your home.
