About Us

National Fiber has been producing cellulose insulation and hydro-seeding mulch in Belchertown MA since 1978.  Our service area covers the Northeast from Canada to Philadelphia and out to Rochester.  In 1997, the company was purchased by MacGregor Bay Corporation, and our equipment represents the leading technologies in the industry.

We make the highest quality cellulose insulation and hydro-seeding mulch in the Northeast.  How can we make such a bold claim?  It's simple.  We use primarily over-issue news, the finest, cleanest newsprint available, free from the trash and debris often found in other manufacturer's product.  We have invested significant capital in our modern factory to ensure we have the latest equipment and technologies.  We take advantage of cutting-edge techniques and hard-won experience.

But producing a quality product is only half the story.  We are also committed to providing the highest quality service and technical support.  Our team of experienced drivers understands the value of your time and delivers our products when you request them, with courtesy and professionalism.  Our technical manager and our technical sales reps are among the most knowledgeable and experienced in the industry.

This combination of long-term experience, modern technology, and dedication add up to a superior product value that can only be built from the ground up.  Our customers enjoy the benefits of that value every day of the year.
