The system complies with the most stringent of standards – from baseline building regulations through to Passivhaus*. The system is suitable for most external finishing
options including metal, clay or slate tiling etc. All components for the system are available below.

The System Sheet will show you all the components required and which bits go where. Please note that to benefit from the BBA certificate all the system components specified must be used.


*NB. Any system designed by NBT as Passivhaus should be verified using the latest PHPP software to ensure the Passivhaus standard can be met. Passivhaus Store does not warrant any such system as being able to achieve the standard.
