Hempcrete Blocks

The ISOHEMP™ hempblock system is a high-performance, carbon neutral building material suitable for domestic or commercial construction projects and for retrofit or renovation.

As a medium-density building material blocks provide both insulation and thermal mass. The blocks can be cut easily with a regular hand saw, or appropriate power tool, to shape and fit around into irregular shapes in the structural frame, or existing walls.

Precast hempcrete blocks have become more popular in recent years, due to the predictability they bring to a hempcrete build. Cast-on-site hempcrete has a drying time on site which is dependent on a range of factors such as thickness, time of year, site exposure to the wind etc. Hempcrete blocks are pre-dried in the factory and laid in a thin layer of lime adhesive mortar, so walls are ready to finish a few days after the blocks have been installed. This means the schedule on site is much more predictable, making them more suitable for commercial scale jobs, or when building in the winter months.

Before building with hempcrete blocks, we urge you or your team to make use of the extensive ISOHEMP™ installation guides. You can find the official guide as well as instructional videos here.
