Durisol is a building system that uses recycled wood to form insulating concrete wall units. The wood is "mineralized" and formed into durable blocks with an open cell structure that provides insulation but does not burn, rot, or support insects. The lightweight blocks are dry stacked without mortar, then filled with concrete to form a monolithic concrete frame. Durisol walls can achieve high insulative values while offering construction cost and time savings compared to traditional methods. The blocks have been used internationally for over 60 years to construct a variety of buildings from houses to schools to high-rises.

16. Build Example: School
“The sound insulation is
fabulous! There is a noticeable
positive difference when you
walk through to the new part of
the school. The sound insulation
adds to a feeling of calm and
there is no echo, even in such a
lofty open space. This is
particularly good for classrooms
for young children as it adds to
the comfort of the space and
allows for calm and quiet as well
as discussion and play.
Thank you”

Teacher, Braunton School
