Highlights

Across Europe, regulations on the energy consumption of homes are becoming more stringent, for example the Near Energy Zero Building (NZEB) conctruction norms . Increasingly passive houses are also gaining popularity. To meet this increasing demand in the market Schiedel developed ISO-block® . This unique construction keeps all the heat inside the house, resulting in considerable energy savings. This system is ideal to include in the specifications for passive houses (and NZEB) and can be used for wall, roof, or floor penetrations. It includes a fire-safe roof penetration designed specifically for roofs featuring thick high-quality insulation layers. Additionally, it is suitable for use with roofs made of combustible materials, such as thatched or grass roofs.

NZEB Pass-through

Until now, when it comes to passing chimneys through the roof, a choice had to be made: ventilation in connection with fire safety or “plugging” the spaces around penetrations with the risk of fire. Which, especially with increasingly thick (insulated) roofs and walls of NZEB constructions, is not an imaginary danger. Moreover, a penetration breaks through the vapor retarding layer of a house, where condensation problems can occur. However...

Maximum Safety

The system features premium insulation material that helps you maintain a zero-centimeter distance from combustible materials, ensuring maximum safety and efficient usage of the available space. The ISO-block remains safe even under long-term thermal loading. The combination ISO-block® with Schiedel chimney systems offers a complete, safe and modern solution. ISO-block has been tested and approved by several independent test centers: VTT (Finland), ChimneyLab (Denmark), MPA NRW, TÜV (Germany).

Easy to Use

With its compact dimensions and lightweight design, this system is incredibly user-friendly. It is easy to finish and comes with a large variety of accessories for both indoor and outdoor installation. Additionally, it is compatible with AT and MF, ensuring seamless integration into your planned new build or retrofit installation setup.
