How to Insulate a Conservatory: A Comprehensive Guide

A conservatory can transform a home’s living space, without a doubt. For it to do that all year round, especially for older conservatories, insulation is the key to success. With so much glass and PVC and of course the UK’s unpredictable weather, it can be a real challenge to keep an ideal temperature without new technologies like modern insulation or roof enhancements.

That doesn’t mean it’s an impossible challenge. There are numerous ways to massively improve your conservatory’s insulation in the UK. After all, doing it enhances comfort, and reduces energy costs in the process, both of which can be game-changing for your conservatories life span and usefulness.

Here are just some of the changes that could make a difference for your conservatory.

 

1. Consider a Tiled Roof Replacement

One of the most impactful changes you can make is to replace your existing PVC or glass roof with a tiled conservatory roof. According to the Conservatory Association, homeowners can save up to 40% on heating costs by upgrading to a tiled roof

This upgrade not only enhances the aesthetics of your conservatory but also significantly improves its insulation properties. Tiled roofs are designed to provide better thermal efficiency, keeping the heat in during winter and preventing overheating in summer. 

Additionally, tiled roofs require less maintenance than their glass counterparts, making them a long-lasting solution that can save you time and money in the long run.

2. Roof Insulation Options

If a complete roof replacement isn’t feasible, there are still effective ways to insulate the existing structure. One option is to add roof insulation using advanced materials like our Eco Hybrid conservatory insulation.

This type of insulation is lightweight yet highly effective at reducing heat transfer. A study by the National Energy Foundation suggests that proper roof insulation can reduce heat loss by up to 25%. 

By installing a false ceiling, you can create a layer of insulation around the roof, helping to maintain a more stable temperature within the conservatory. This method not only improves comfort but also contributes to energy savings by reducing the need for heating and cooling.

3. Upgrade Your Glazing

Another essential factor in conservatory insulation is the quality of your glazing. If your conservatory features single glazing or even older double glazing, consider upgrading to double glazing. 

According to the Energy Saving Trust, replacing single glazing with A-rated double glazing can improve thermal efficiency by up to 40%. Double-glazed windows have an insulating layer of gas trapped between two panes of glass, which greatly improves thermal efficiency. This upgrade can significantly reduce heat loss in the winter and minimise heat gain in the summer.

It’s also very much worth noting here that regular maintenance of existing windows and doors is crucial too. Ensure that seals and frames are in good condition, as damaged seals can lead to drafts and energy loss. If your conservatory has older glazing, it may be worth consulting a professional to assess whether replacements or upgrades are needed.

4. Floor Insulation

The floor of your conservatory can also contribute to heat loss, so adding insulation here is essential. Insulation boards can be installed directly onto the floor, creating a barrier against cold from the ground. 

According to the Department for Business, Energy & Industrial Strategy, around 10% of heat loss in a home can occur through uninsulated floors. If you’re considering floor insulation, underfloor heating can also be a practical solution, providing warmth without taking up valuable space.

5. Use Curtains and Blinds

In addition to structural improvements, soft furnishings can also play a significant role in insulation. Heavy curtains or thermal blinds can help retain heat during the winter months and block excessive sunlight in the summer.

A report from the University of Salford indicates that proper use of curtains can reduce heat loss by up to 15%. Investing in high-quality thermal blinds can make a noticeable difference in maintaining a comfortable temperature in your conservatory.

Bonus Tip: Consider Solar Control Glazing

If you’re looking to manage heat gain during the summer, consider solar control glazing. This type of glass is designed to reflect more sunlight while still allowing light to enter, keeping your conservatory cooler during hotter months. 

According to Pilkington, using solar control glass can reduce solar heat gain by up to 50%, making it an excellent option for those sunny summer days.

Conclusion

With the potential to save on heating costs and improve the overall energy efficiency of your home, insulating your conservatory can be essential. With multiple options available to you and technology on the market now that can truly transform an older conservatory, it’s a great time to go about it. Whether you’re hosting guests or enjoying a quiet evening, a well-insulated conservatory will provide a comfortable and inviting space for years to come.
