Fiberboard, a plant that makes heat resistant insulation, makes more than $100 million in profit

A plant that uses hemp fiberboard for insulation made $100,000 last year in sales of its products, including insulation, fiberboard and insulation material, the company said in a filing Thursday.

Fiberboard is made from hemp, a highly fiber-reactive fiber, and the company reports that hemp insulation sold for $12.6 million in 2016.

Hemp, which is grown in California and Oregon, has been a mainstay of the construction industry since the early 1900s, but has since become an agricultural commodity.

It is a durable fiber, a byproduct of the fiber-making process, and is commonly used for insulating windows, doors and doors and other structures.

The company reports it has been in business for more than 30 years, with the latest product sales from last year being $2.5 million.

It also reported it had more than 1,400 employees in the United States, including 1,000 workers in the San Francisco Bay Area.

The company had revenues of $4.3 million in fiscal 2017, including $1.1 million from sales of fiberboard insulation.
