Company History
1940's
The Inspiration
Historically, mud, sticks, leaves, straw and other materials have been used to seal the gaps and cracks in dwellings to prevent air movement in and out of the structure. Â In the 1940’s, it was common for people to glue newspapers to their walls to help with air infiltration and to keep their homes warm. Â This simple activity was the inspiration for cellulose insulation.
1949 - the late 1960's
In the Beginning
In 1949, as insulating homes became popular and the supply of quality cellulose insulation was minimal, our founder, Al Altenbernt, saw an opportunity and began creating his own cellulose to install – Nu-Wool Insulation. By the late 1960’s, the demand for Nu-Wool was significant so the company decided to stop installing and only sell to other contractors and retailers. Â
1970's
Recognition
Beginning in the 1970’s, Nu-Wool started receiving recognition for its innovative ideas due to our commitment to quality and to helping our customers reach their full potential. Our innovation has spread into all facets of our operation, beginning with our manufacturing process, raw materials, mechanical support, equipment fabrication, technical support and training of inside and outside sales staff.

Their son, Mark Henderson, joined the company in 1996, and took the reins as President in 1998. The company is currently owned by Mark and his wife, Valerie.
