Typically, a U-value target of 0.15 W/m²K is sought after to ensure excellent thermal performance on flat roofs. Traditionally, meeting this target on an inverted roof situation required a substantial 240mm thickness of regular XPS insulation. However, there's an exciting development that can help streamline the insulation process.
Introducing PLUS300, an advanced insulation solution that allows you to achieve the same U-value target with a reduced thickness of just 180mm! 🎉
Using Jackodur XPS insulation, specifically the PLUS300 (lambda value of 0.027) and the new Jackodur Evo (lambda value of 0.032), offers significant benefits from both a design and carbon point of view. Here are the advantages:
Optimal Space Utilisation: The exceptionally low lambda values of Jackodur PLUS300 and Jackodur Evo allow for up to 25% more square meters (M2) of insulation to be loaded onto a single truck. This maximises the utilisation of transportation capacity and reduces logistical costs, making it more efficient to deliver insulation to construction sites.
Thinner Insulation Profiles: The low lambda values of Jackodur XPS enable insulation thickness to be reduced by up to 25%. This reduction is particularly valuable for inverted flat roofs where space is limited. By utilising thinner insulation profiles, designers can achieve the desired thermal performance while minimising the overall height of the construction, optimising space usage and providing flexibility in design.
Simplified Installation: one notable advantage is the wide range of thickness options available. Jackodur offers single sheet thicknesses ranging from 30mm up to 400mm. eliminates the need for double or triple layering to achieve the desired insulation thickness and U-value. This simplifies the installation process by reducing the number of layers required and streamlining the overall construction timeline while also minimising human error
Energy Efficiency: The excellent thermal insulation properties of Jackodur XPS contribute to enhanced energy efficiency in buildings. By reducing heat transfer through the building envelope, it minimises the need for heating and cooling, resulting in lower energy consumption and reduced carbon emissions. This energy-saving aspect helps to mitigate the environmental impact associated with buildings.
Lower Embodied Carbon: Jackodur XPS panels have a low embodied carbon footprint. Embodied carbon refers to the total greenhouse gas emissions generated during the manufacturing, transportation, and installation of a material. By choosing Jackodur XPS with its low lambda values, architects and builders can minimize the carbon emissions associated with the insulation's life cycle, contributing to a more sustainable construction process.
Reduced Transportation Emissions: The ability to load up to 20% more insulation on a single truckload due to the low lambda values of Jackodur PLUS300 and Jackodur Evo translates to fewer transportation trips. This reduction in transportation requirements leads to lower fuel consumption and associated emissions, further reducing the carbon footprint of the project.
Durability and Longevity: Jackodur XPS insulation is known for its durability and long lifespan. By using a reliable and long-lasting insulation solution, the need for insulation replacement is minimized. This longevity reduces waste generation and the environmental impact of disposal, contributing to a more sustainable approach.

In summary, the use of Jackodur XPS insulation, such as the PLUS300 and Jackodur Evo, offers design benefits such as optimal space utilisation and thinner insulation profiles, especially valuable for inverted flat roofs. From a carbon perspective, it provides energy efficiency, lower embodied carbon, reduced transportation emissions, and enhanced durability. By leveraging the lowest lambda values available in the market, Jackodur XPS enables architects and builders to optimize space, reduce costs, and contribute to a more sustainable and environmentally friendly construction process.
