Design for a more sustainable world
with HempWool® 

As architects, designers, energy modelers, and green building experts, we have a responsibility to do better.

Buildings and their operations are responsible for approximately 40% of our energy consumption and 40% of our carbon footprint. We can't keep designing with the same materials and expecting that we'll have different results

We must design more responsibly, with more sustainable materials. 

HempWool® is the only thermal insulation product that has a biogenic carbon uptake, while also maintaining the efficiency of the thermal envelope.



Learn why HempWool is the sustainable insulation.


At Hempitecture,
our insulation
begins with a

HempWool is created using the fiber from industrial hemp, grown sustainably in rural communities across the United States. These seeds grow into a crop that offsets 9.8 tons of CO2 per acre.

That's the equivalent of taking 2.1 cars off the road for a year.

The harvested fiber is processed and transported to our US manufacturing facility.

Our manufacturing facility, coming online in Q2 of 2022, will utilize renewable energy and a state of the art manufacturing process that is capable of producing millions of square feet of HempWool per year.

The resulting insulation
product is carbon negative.

A life cycle analysis conducted at our current manufacturing partners facility shows signs that HempWool is a promising solution for embodied carbon in the built environment. 

HempWool shows a biogenic carbon uptake greater than its biogenic carbon output. 

Meaning, HempWool is a carbon negative insulation that can drive more sustainable outcomes for your project.
