The whole house is much more comfortable. The temperature throughout the house is much more even. I appreciate your personal attention, flexibility and the work ethic of your crew.

Welcome to Farnum Insulators

 

Awarded "Most Thermal Savings" and "Most Projects" for a small company in 2016 by Efficiency Vermont's Efficiency Excellence Network

New England’s weather requires buildings to have a higher standard for insulation than many other parts of the country. With decades of building and contracting experience, we saw firsthand how poorly fiberglass insulation performs — leading to lost money, less comfort and wasted energy resources.

We work with homeowners, businesses, and institutions to:

  • Assess your building’s insulation needs through thorough diagnostic testing

  • Create the most cost-effective and non-invasive plan to increase your energy efficiency

  • Find all available cost saving incentives and grants to reduce your costs

  • Help you enjoy your home or place of business more than you ever have

Building Performance Institute certified and focused exclusively on insulating homes and businesses, we are the most trusted name in insulation. Contact us today to start saving money.

cellulose insulation

Cellulose is a great insulation material with a high R-value. It’s treated against fire, mold and pests as well as being made from recycled material. We can work in new or existing structures and we’ll help you choose the most cost-effective and non-invasive methods to meet your insulation needs.

foam insulation

Sometimes cellulose isn’t the best option. Damp basements, rim boards and some wall cavities are best insulated using this amazing spray-on foam. With high R-value, an ability to expand into a space and airtightness, we’ll advise you on which insulation is best for you.
