01
What a wall can do
Hemp-lime can buffer changes in indoor humidity. Finishes influence that exchange, but it does not remove cooking pollutants or replace a designed fresh-air supply.
PRACTICAL HEMP GUIDES
Breathable walls still need fresh air
Moisture buffering and ventilation do different jobs.

Moisture buffering and ventilation do different jobs. This is educational planning guidance, not a construction specification.
02
What ventilation does
A suitable ventilation strategy manages indoor air as part of the whole-home design. Air leaking randomly through construction is not a reliable substitute.
03
Coordinate comfort
Insulation continuity, heating, shading and ventilation all affect experience inside the home. A material choice cannot guarantee freedom from condensation or overheating.
04
When a home has problems
Investigate water ingress, cold surfaces and ventilation alongside heating and use. Damp and mould can harm health; address causes promptly and seek relevant professional advice rather than relying on a miracle-material claim.
