Insulated panels offer
for roofing and cladding across various building types.
Insulated panels
What are insulated panels?
Insulated panels are an advanced roofing and cladding product often used for commercial buildings designed for thermal efficiency and durability. Also known as ‘all-in-one’ or ‘sandwich’ panels, they are comprised of two 0.5mm thick steel sheets with a core of PIR (polyisocyanurate) insulation. Available in various thicknesses, insulated panels protect against moisture ingress and temperature variation and provide fire resistance. The outer steel layer offers robust protection against the elements, while the inner surface has a white liner that acts as the finished ceiling, enhancing light reflection and providing a clean, modern look.
These panels offer significant advantages compared to traditional roof systems comprising of multiple built-up layers. They simplify installation by combining insulation, structural support, and weatherproofing in one step, reducing construction time and labour costs. Consistent factory-controlled manufacturing of the panels ensures reliable thermal performance and a tight seal, which minimises air leakage and improves energy efficiency. Unlike built-up systems, which can require a complicated installation process, insulated panels provide a straightforward, durable solution, making them an ideal choice for energy-efficient building projects.
Key features
Cut-to-length
Panels can be supplied precisely cut to the specific length you require. Simply specify the exact panel lengths needed (up to a maximum panel length of 20 metres) and panels are cut to these dimensions, ensuring that each piece fits without additional adjustments.
Key benefits of cut-to-length panels:
• reduces on-site cutting
• minimises waste and labour time
• lessens the risk of errors during installation
Cut-to-length insulated panels are usually produced in 2 to 4 weeks, depending on stock availability and specific requirements. This can vary based on demand and production schedule.

Take-offs and installation guidance
We also provide a take-off service, assisting you with measuring and quantifying the materials needed for your project. Whether you’re working from architectural drawings or a quick sketch, we can help you stay on schedule and within budget.
Installation guidance is also available, giving you access to expert advice tailored to the specific needs of your project, whether you are a seasoned contractor or new to installing insulated panels. We can provide step-by-step instructions and best practice tips to ensure your panels are installed correctly, maximising their performance and longevity. With our support, you can avoid common pitfalls, reduce installation time, and enhance the overall quality of your build.
What are cut-backs?
A cut-back refers to the end of the panel where the insulation and liner sheet are factory cut at a shorter length than the top steel sheet. Cut-backs can be made at different lengths and need to be specified at the time of order.
There are two purposes for cut-backs:
1. To create a drip edge on the panel that ensures water run-off into a gutter. Gutter cut-backs are usually produced from 50mm to 75mm long.
2. To ensure a watertight overlap where two sheets join end-to-end. This could be two panels fastened together or where an insulated panel joins a rooflight sheet. We recommend a minimum end lap cut-back length of 150mm.
Please note: The overall length of the sheet is determined by the length of the top sheet rather than the liner sheet length, which will be shorter.
What is handing?
Insulated panels can be installed either from left to right or right to left. Each panel is manufactured with a side lap detail where the top sheet projects beyond the insulation and liner sheet; this will then lap onto the crown of the previously laid panel. Left to right or right to left handing must to be specified at the point of order. Panels should be installed with the overlaps facing away from the prevailing wind. This will determine the handing of the panels.
For standard-pitched roofs, it is common practice to order the panels ‘50% handed’; half laid left to right and half laid right to left.
Guarantees
