The hempcrete wall: an overview - The Hempcrete Topic: Designing and Building with Hemp-lime - page 221

Angled window reveals are attractive within a deep hemp-
crete wall and maximize the amount of light.
Openings for doors and windows are created as part of the structural frame, or by an ad-
ditional framework secured to it. In either case vertical and horizontal timbers define the
opening and provide a fix for the window or door frame (see Chapter 13 ) . Shuttering, either
temporary or permanent, is constructed to run around the inside of this framework, so that
when the hempcrete is cast, that section of the wall is left open, with the framework for the
opening flush with the surface of the hempcrete in the reveal.
Where shaped reveals are desired, these can either be formed using the shuttering or the
hempcrete can be shaped after it has been cast (see Chapter 22 for more details).
