DIY Installation vs. Professional Installation – The Pros and Cons
Hopefully this section will give you some food for thought as to whether a DIY approach to this task is the best idea.
The DIY Approach
One of the most appealing aspects of a DIY approach is the potential for significant cost savings. By taking on the project yourself, you can avoid the labour expenses associated with hiring professionals, making it a more budget-friendly option. Additionally, there’s a deep sense of personal satisfaction that comes from completing a project with your own hands. The ability to work on your own schedule also adds flexibility, allowing you to tackle the insulation at your own pace.
However, there are some drawbacks to consider. Insulating a conservatory can be time-consuming, particularly if you’re unfamiliar with the materials or techniques required. Tasks that might take a professional just a couple of days could stretch into weeks for a DIYer. Not all aspects of insulation are straightforward; some require a higher level of skill and experience. Without this expertise, there’s a risk of making mistakes that could compromise the effectiveness of the insulation or even cause damage. Additionally, the quality of a DIY job might not match the precision that professionals can achieve, which could impact the overall success of the project.

Hiring Professionals
Opting to hire professionals brings several advantages, primarily their expertise and experience. Professionals are well-versed in the best materials and methods for insulating a conservatory, ensuring that the job is done correctly from the start. Their efficiency is another key benefit; a professional team can complete the project much more quickly than a DIY effort, minimising disruption to your daily life and providing faster access to a more comfortable conservatory. Furthermore, professional work often comes with a guarantee or warranty, offering peace of mind that any issues will be addressed at no additional cost.
On the downside, hiring professionals generally comes with a higher price tag. The cost of labor can make the project more expensive, which could be a concern if you’re working within a tight budget. Additionally, bringing in professionals means giving up some control over the project. You’ll need to coordinate schedules and trust that the work will meet your expectations. The presence of a work crew can also be disruptive, especially if the installation takes several days, requiring you to accommodate noise, mess, and the presence of workers in your home.
Professional installers also have access to specialist insulation panels that aren’t available to the general public. They combine both ease of installation and provide maximum thermal and acoustic efficiency.


Deciding whether to tackle conservatory insulation as a DIY project or to hire professionals depends on various factors, including your budget, time availability, and comfort level with home improvement tasks. If you feel confident in your abilities and have the time to dedicate, DIY might be a rewarding and cost-effective option. However, if you prioritise efficiency, guaranteed quality, and peace of mind, investing in professional installation could be well worth the additional cost.
The Different Types and Approaches to Conservatory Insulation
Here’s a list of conservatory insulation types which can be used on their own or grouped for maximum efficiency.
Roof Insulation

Insulated Panels are highly effective for conservatory roof insulation, providing excellent thermal efficiency with a low U-Value. These panels are durable, watertight, lightweight, and easy to install, making them suitable for most conservatories. They come in various finishes to help maintain or enhance your conservatory’s light and appearance.

Multi-foil Insulation: A reflective foil insulation that’s installed on the inside of the roof, often combined with other layers for added thermal efficiency.

Quilted Thermal Insulation Rolls are another effective option. These rolls, typically made from layers of reflective foil and insulating material, can be fitted under your existing roof to enhance thermal performance. They are lightweight, flexible, and easy to install, providing a cost-effective way to improve insulation without major alterations.

Tiled Roofing offers a traditional look and superior insulation. However, it’s important to ensure that your conservatory’s framework can handle the added weight. While tiled roofs can reduce natural light, installing skylights can help maintain brightness.

For a less invasive solution, Tinted Glass or Window Film helps manage heat and glare, reducing the greenhouse effect during summer. Though they offer minimal insulation benefits, they are straightforward to apply and maintain.
Thicker Polycarbonate Panels offer improved insulation over standard panels but may require adjustments to your roof structure. They are lightweight and allow plenty of light in but can be noisy during rain and degrade over time.

Triple Glazing provides a good balance between insulation and natural light, outperforming double glazing and polycarbonate panels. However, it may require a stronger framework and regular cleaning to maintain its clarity and effectiveness.
More Conservatory Insulation Options
- Window and Glazing Insulation
- Double or Triple Glazing: Upgrading to double or triple-glazed windows improves thermal efficiency by reducing heat loss through the glass.
- Thermal Blinds and Curtains: Specially designed blinds or curtains can add an extra layer of insulation to your conservatory windows.
- Floor Insulation
- Insulated Floorboards: Installing insulated floorboards beneath your conservatory flooring can prevent heat loss and make the space warmer.
- Thermal Underlay: A layer of insulating material placed under carpets or other flooring types to enhance heat retention.
- Wall Insulation
- Insulated Plasterboard: Similar to roof insulation, insulated plasterboard can be applied to the internal walls of the conservatory, reducing heat loss and improving energy efficiency.
- External Cladding: Insulating cladding applied to the exterior of the conservatory walls can help protect against heat loss and improve the overall insulation of the structure.
- Roof Insulation Inserts
- Polycarbonate Inserts: These are designed to fit into existing polycarbonate roofing panels, adding an extra layer of insulation while maintaining the original roof design.
- Thermal Paint
- Insulating Paint: Specially formulated paint that reflects heat back into the conservatory, reducing heat loss through the walls and roof. It’s often used as a supplementary measure in combination with other insulation types.
Each of these options offers varying levels of insulation and can be combined to achieve the desired level of comfort and energy efficiency in your conservatory.
Design Considerations
Aesthetic Impact
When upgrading your conservatory’s insulation, it’s important to consider how different options will affect the overall look and feel of the space. The insulation type you choose can influence both the interior and exterior appearance of your conservatory:
- Insulated Panels: These panels often come with various finishes, allowing you to customize the look of your conservatory. For a bright and airy feel, you can select panels with a reflective coating on the underside to bounce light around the room. Alternatively, matte finishes provide a cozy, ceiling-like appearance. On the exterior, insulated panels are generally sleek and modern, complementing many architectural styles.
- Tiled Roofing: Tiled roofs offer a traditional and elegant look, blending seamlessly with the rest of your home. While they provide excellent insulation, they can reduce natural light entering the conservatory. However, the addition of skylights can mitigate this effect, allowing you to maintain both aesthetics and brightness.
- Tinted Glass or Window Film: These options are less intrusive and preserve the glassy look of your conservatory while reducing glare and heat. They are a good choice if you want to maintain the transparency of your conservatory but can be less effective in insulating against temperature extremes.
- Thicker Polycarbonate Panels: Upgrading to thicker polycarbonate panels can enhance insulation while maintaining a similar appearance to your existing roof. Though polycarbonate allows ample light, its appearance can sometimes be less refined compared to other options.
Balancing aesthetics with functionality involves selecting insulation that complements your conservatory’s style while meeting your thermal needs. Choose materials that blend with your decor and enhance the overall ambiance without compromising on comfort.
Integration with Existing Features
Integrating new insulation with your conservatory’s existing features requires careful planning to ensure a seamless transition:
- Skylights: If your conservatory has skylights, you’ll need to consider how insulation will impact their placement and effectiveness. Insulated panels and multi-foil rolls can be installed around skylights, but ensure that the installation does not obstruct the light or view. For tiled roofing, adding skylights during the installation process will allow for optimal integration.
- Ceiling Fans: When installing insulation, ensure that ceiling fans remain functional and are not obstructed. Insulated panels and quilted thermal rolls should be installed carefully around fans to avoid interfering with their operation. If upgrading to a new roof, consider whether fan placement needs to be adjusted or if additional supports are required.
- Light Fixtures: Ensure that new insulation materials do not interfere with existing light fixtures. Insulated panels and other materials should be installed with adequate spacing to accommodate fixtures and prevent overheating. If you are installing new ceiling insulation, consider repositioning or updating light fixtures to fit the new setup.
Incorporating insulation while preserving the functionality of your conservatory’s existing features can enhance both its comfort and aesthetic appeal. By planning carefully and choosing compatible materials, you can achieve a well-integrated and visually pleasing result.
