Sierra Pacific Windows is a division of Sierra Pacific Industries. SPI is a private California corporation owned by the Emmerson family, with forestlands and manufacturing facilities in northern California and Washington. Sierra Pacific Industries was started in the 1940s by A.A. (Red) Emmerson and his father R.H. (Curly) Emmerson with one sawmill employing 8 to 10 people in Humboldt County. Sierra Pacific Industries has grown to be one of the top manufacturers of lumber, millwork, wood windows and doors in North America, employing approximately 4000 employees. Sierra Pacific is also the largest owner of private industrial forestlands in California.

All of the 1.9 million acres of forestlands owned and managed by Sierra Pacific meet or exceed the Sustainable Forestry Initiative standards. Sierra Pacific is committed to the practice of sustainable forestry – meeting the needs of the present without compromising the ability of future generations to meet their own needs. To achieve this, Sierra Pacific Industries is dedicated to a land stewardship ethic, which integrates the reforestation, management, growing, nurturing and harvesting of our forests with the conservation of soil, clean air, water and habitat for fish and wildlife. As a participant in the SFI program, they have pledged to use only sustainable forestry practices that are economically, socially and environmentally responsible.
