If you are planning to replace your existing conservatory roof panels with insulated conservatory roof panels, accurate measuring is one of the most important steps. You may be asking yourself: ‘How do I measure for conservatory roof insulation panels?’
Correct measurements help ensure that the panels you order are suitable for your conservatory structure, fit properly once cut on site, and provide the best possible insulation result.
At Conservatory ThermoPanels, we supply insulated conservatory roof panels in standard panel sizes. Customers usually order the most suitable full-size panels for their project and then cut them on site to match their existing conservatory roof sections.
In this guide, we explain how to measure your conservatory roof panels correctly before placing an order.

How Do I Measure for Conservatory Roof Insulation Panels? From the Outside or the Inside?
When measuring for conservatory roof insulation panels, measurements should be taken from the outside of the conservatory roof, not from inside the conservatory.
This is because the panels sit within the external roof structure, between the glazing bars or roof sections. Measuring from the inside may not give you the correct size for replacement panels.
For each roof section, you should measure:
- The full length of the panel section
- The full width of the panel section
- The thickness of the existing panel
It is important to measure each section individually, especially if your conservatory roof has different shapes or smaller side sections.
Measure Between the Roof Sections
Your measurements should be taken between the roof sections or glazing bars where the existing panels sit.
For each panel section, measure the maximum length and width required. This will help you work out how many insulated panels you need to cover the full roof area.
Conservatory roofs often include a mixture of larger and smaller sections, especially on Victorian, Edwardian, P-shaped or irregular conservatory designs. For this reason, it is best not to assume that all panels are exactly the same size.
Measure each section carefully and make a note of:
- How many roof sections you have
- The length of each section
- The width of each section
- Any smaller or shaped sections that may need to be cut from a larger panel
Check the Existing Panel Thickness
Before ordering new insulated conservatory roof panels, you should check the thickness of your existing roof panels.
To do this, you may need to remove the end closer at the gutter end of the conservatory roof. This should allow you to see and measure the actual thickness of the current panel.
We usually recommend replacing like-for-like thickness where possible. This means choosing a new insulated panel that matches the thickness of your existing panel as closely as possible.
This is important because the panels need to fit into the existing conservatory roof structure, glazing bars and components. Choosing the correct thickness helps achieve a better fit and makes installation more straightforward.
Use the Existing Panels as Templates
One of the best ways to achieve an accurate fit is to use your existing conservatory roof panels as templates.
Once the existing panels are removed, they can be used to mark the required shape and size onto the new insulated panels before cutting.
This is especially useful if your roof has angled sections, unusual shapes, or smaller side panels. Using the original panels as templates helps reduce the risk of mistakes and allows the new panels to follow the same shape as the existing roof layout.
Our Panels Are Supplied in Standard Sizes
Conservatory ThermoPanels are supplied in standard full panel sizes and are designed to be cut on site to suit your project.
We do not offer a cut-to-size service. Customers should order the most suitable standard panel sizes and arrange for the panels to be cut during installation.
Our standard white PVC-UV insulated conservatory roof panels are available in a range of practical sizes, including smaller and larger panel options. Larger panels can often be a more cost-effective solution because they may cover multiple roof sections, including smaller sections that can be cut from the same panel.
This can be particularly useful for larger conservatories or roofs with several smaller panels.
Larger Panels Can Be More Cost-Effective
For some projects, ordering larger panels may help reduce the total number of panels required.
For example, if your conservatory roof has several smaller sections, these may be cut from a larger standard panel. This can sometimes be more cost-effective than ordering multiple smaller panels separately.
Before placing an order, it is useful to calculate how the roof sections can be arranged across the available panel sizes. This helps you make the most of each panel and reduce unnecessary waste.
For larger projects, we also recommend having two people involved in measuring and handling the panels. Larger panels are lightweight compared with many traditional roofing materials, but their size means they are easier and safer to measure, move and cut with two people.
Information We Need to Provide an Accurate Quote
To provide you with an accurate quote, we kindly ask you to calculate and provide the following information before submitting your enquiry:
- The total number of panels required
Please calculate how many panels you need to cover all roof sections of your conservatory. - The most suitable panel dimensions
Our panels are supplied in standard sizes and are cut on site by the customer or installer. Please check which standard panel sizes would be most suitable for your project. Larger panels can often be a more cost-effective option, especially if several smaller roof sections can be cut from one larger panel. - The required panel thickness
Please check the thickness of your existing roof panels. We usually recommend replacing like-for-like thickness where possible, as this helps the new panels fit correctly into your existing conservatory roof structure. - Your delivery address
Please provide the full delivery address, including postcode, so we can confirm whether our courier covers your area and advise the correct delivery cost.
Once you have this information, please submit it through the contact form on our website. Our team will then review your enquiry and get back to you with a quote.
Cutting the Panels on Site
Our insulated conservatory roof panels are supplied in standard sizes and are designed to be cut on site to suit your conservatory roof.
For the best results, we recommend using your existing roof panels as templates wherever possible. This can help achieve a more accurate fit, especially if your conservatory roof includes angled sections, shaped panels or smaller side sections.
The panels can be cut using a fine-tooth hand saw or an electric saw. For the cleanest and neatest cut, we would usually recommend using an electric saw with a fine-tooth blade. In general, the more teeth the blade has, the cleaner the cut will usually be.
A saw with a dust bag or dust extraction attachment can also be very useful, as it helps minimise dust while cutting.
Always take care when cutting and handling the panels. Make sure each panel is well supported while being cut, and for larger panels, we recommend having two people to help with handling and positioning.
