Doppelhaus

The Company

Doppelhaus develop sustainable, non-woven materials for the fashion industry. Their first material Cloudwool® uses undervalued British wool and bonds it through a novel non-woven process, resulting in a lighter, more flexible felt fabric for apparel and footwear. 

R&D Focus 

The BFTT project focused on developing and manufacturing the non-woven textile at an accessible price point and with strong aesthetic and functional appeal that could have a positive environmental impact through mass market applications. 

Through creative R&D, Doppelhaus successfully developed a fully traceable supply chain for British wool and improved the performance attributes of the non-woven material through partnerships with innovative technology providers.  

Doppelhaus have since collaborated with British shoemaker Grenson, to develop a shoe made from Cloudwool®, launched in Spring 2023.
