[Strawbale] Alternative tightening materials

[Sara Tommerup]

Hello out there,

I would like to know if anyone has information on low embodied energy
Passive House DETAILS, such as alternative solutions to foam, tape and
membranes so often used in passive house construction. Straw bale is
obviously a brilliant choice to reduce the overall embodied energy,
however, how do you go about the air tightening for a 0,6 ach/h value
in a straw bale house or frame with another low tec natural insulation
if you don't want to use foam, tape and membrane (etc)?

Any references, personal experiences and inventions are welcome:O)

Kindly
Sara Tommerup
