Insulated Roof Panels

Insulated Roof Panels

Metal insulated roof panels are a practical and cost-effective way to make a building energy efficient as well as regulating temperature throughout the year – keep the internal environment cooler in summer and warmer in winter. In addition, the insulation can help reduce condensation, which provides health benefits to occupants and workers by reducing mould and damp, whilst protecting the building fabric from corrosion.

Insulated roof panels consist of an external and internal metal sheet, which are usually made of galvanised painted steel. Standard sheet thicknesses tend to be between 0.4mm to 1.0mm, which offer a variety of strengths as required. Insulation is available in both polyurethane and polyisocyanurate (PUR and PIR) as well as rockwool (also known as mineral wool). When choosing the type of insulation, flammability and resistance, or structural characteristics such as thermal and moisture protection, should be considered.

Insulated roofing sheets often have a trapezoidal box profile structure. There is an alternative option of corrugated profile and traditional tile-aesthetic. These provide metal roofing panels with extra rigidity whilst creating an appealing aesthetic and reduced installation times.

Gordian Building Solutions offer a wide range of insulated metal roof panels with up to a 40 year guarantee – assured longevity for most buildings. This provides you with the confidence that you are making the best investment in terms of long-term energy efficiency and low maintenance.

Gordian Building Solutions provides insulated roof panels from the leading suppliers including; Kingspan, Tata, Joris Ide and many others. Some of the benefits from using insulated roofing sheets as opposed to traditional roofing alternatives are as follows:

Cost Effective:

25% of all heat can be lost through poorly insulated roofing, which results in increased costs that are reflected on your energy bills. Insulated metal roof panels also offer rapid construction, incredible durability and energy efficiency, driving down overall installation and operating costs.

Design Flexibility:

Insulated roofing panels are supplied in various profiles, colours and custom modular widths, providing aesthetically pleasing design options for horizontal installation. They are available for concave and convex roof designs.

Ease of installation:

Insulated roofing panels are available in a wide range of thicknesses to meet building regulations and achieve the required u-values. They are easy to install and are less labour-intensive compared to traditional, built up and twin skin metal roofing solutions which usually have several layers and components. The ‘one layer’ or one component aspect of insulated roofing sheets means that a larger area can be covered in a shorter time.


Galvanised painted metal components not only last longer, but they age well too. Insulated Roofing Panels are manufactured from the highest quality of materials, using state-of-the-art production equipment and rigorous quality control standards to ensure long term reliability and service life.

Healthy buildings:

Gordian Building Solutions’ Insulated metal Roof Panels offers effective solutions for combatting condensation on the underside of roofs. When temperature and humidity conditions reach the dew point, moisture in the air condenses on the underside of uninsulated metal roof sheets. These droplets can fall causing damage to the contents below or accelerate corrosion of the building structure. Our insulated wall panels tackle this issue by ensuring the temperature on the panel never reaches dew point. A range of ventilation accessories also ensure constant circulation of air to reduce relative humidity and create healthier buildings.

Acoustic performance:

In certain kinds of building such as schools, factories and agricultural sector eliminating reverberation across the roof caused by high winds is a necessity. For example, animal welfare or health and safety reasons in a busy manufacturing environment. Our Insulated Roof Panels are proven to help in this area.
