Passive EcoRoof is an advanced building system designed by Ecological Building Systems, combining the latest in sustainable technology with natural materials for energy-efficient and comfortable living spaces. Based on the renowned Passivhaus standard, this system ensures outstanding thermal performance, airtightness, and moisture control for a healthier, more sustainable environment.
At the heart of Passive EcoRoof is Gutex wood fibre insulation, Pro Clima Intello Plus intelligent vapour control membrane and Pro Clima Solitex Plus windtight membrane. These components work together to create a high-performance structure that maximises energy savings and minimises the risk of condensation, which is crucial in the UK and Ireland climates.
This flexible system was designed to allow specifiers to adjust frame depth and insulation thickness to meet various thermal resistance requirements, from the Passivhaus backstop of 0.15 W/m²K to 0.10 W/m²K. Whether used for new builds, timber-framed buildings, or retrofits, Passive EcoRoof ensures excellent thermal and acoustic insulation, meeting or exceeding Passive House standards.
Incorporating natural, low-carbon materials such as Gutex Thermoflex, Thermafleece sheep’s wool, or IndiBreathe Flex further reduces the system's environmental impact by lowering the embodied carbon of building materials. This, combined with its performance levels and flexibility, makes Passive EcoRoof a cutting-edge solution for energy-efficient and sustainable construction.
With comprehensive technical support from Ecological Building Systems, including U-value calculations, WUFI modelling, and construction details, Passive EcoRoof ensures optimal performance and compliance with building regulations.
About Passive EcoRoof
Passive EcoRoof is a forward step in sustainable construction. It was designed to offer the ideal balance of insulation, airtightness, and moisture control. The system includes a continuous layer of Gutex Multitherm external wood fibre insulation, to provide excellent thermal resistance that effectively eliminates thermal bridging via the frame timbers. The flexible Gutex Thermoflex insulation fits between timber studs, offering customizable thicknesses for varying energy performance needs.
In addition to its high thermal mass, which helps reduce summer overheating, Passive EcoRoof features Intello Plus airtight internal vapour control membrane sealed with Pro Clima airtight tapes. With the ability to achieve U-values from 0.10 W/m²K, Passive EcoRoof is perfect for achieving Passivhaus standards.
The use of natural materials, including wood fibre with a carbon negative production process, and flexible sheep’s wool or hemp insulation, also supports a sustainable, low-carbon approach to construction. Passive EcoWall® is an ideal solution for timber-framed buildings and modular homes, offering lasting energy efficiency, comfort, and environmental benefits.
Passive EcoRoof provides a low-carbon, energy-efficient building solution for roofs, combining airtightness, thermal performance, and moisture management with sustainable, natural materials. The use of a highly breathable external membrane reduces condensation and mould risk in the fabric of the roof, while the use of wood fibre insulation ensures excellent thermal and acoustic properties. The system is designed to reduce both operational and embodied carbon, making it a sustainable choice for new builds and retrofits alike. With customizable thermal performance, it ensures compliance with Passivhaus standards, offering a comfortable, healthy indoor environment year-round.
