The lime present throughout the cast material helps to protect the various elements within
the finished wall from rotting when exposed to moisture, and also inhibits insect attack.
Hemp shiv is not, in any case, an attractive food source for insects.
Hempcrete provides a means of creating walls, ceilings and floors that are insulating, yet
are made from sustainable materials (hemp is a renewable, locally grown plant, while lime
is derived from abundant naturally occurring material and has a lower embodied energy
than cement). It is particularly relevant to those wanting to build in a low-impact, sustain-
able way, and for upgrading the thermal performance of historic buildings in a way that
works harmoniously with the original fabric of the building.

Although the oldest hempcrete building is only a few decades old, there is no evidence
to suggest that properly maintained hempcrete will not last for the lifetime of the average
