Spray Foam Insulation
Portsmouth, NH 

Did you know that Anderson Insulation maintains the largest fleet of spray foam dedicated trucks in the Northeast? For 75 years, we’ve been known as the regional spray foam powerhouse. Spray foam is an excellent insulation option for new construction or remodeling projects—we work with both open-cell and closed-cell spray foam to ensure you get the best choice for your project. We work with Huntsman Building Solutions and Carlisle Spray Foam. Spray foam is an excellent insulation option as it adheres to most surfaces and expands after application to create a seamless, airtight barrier. 

Fiberglass Insulation
Portsmouth, NH 

As one of the most common insulation types, Fiberglass is made up of tiny particles of glass and is an effective insulation material for various applications. At Anderson Insulation, we utilize Manville Fiberglass and Knauf Fiberglass manufacturers. Fiberglass is a great option to provide incredible thermal and acoustic protection, creating a quiet, cozy atmosphere year-round. It also protects against mold growth and moisture build-up, perfect for homes near water or in rainy climates. If you’re unsure what insulation to use, our installers can help you decide which option suits your project. 

Blown-In Insulation
Portsmouth, NH 

Back in the 1970s when Anderson Insulation was just starting out, many homes were built with little or no insulation. We utilize Nu-Wool Insulation, an environmentally friendly option made from recycled paper, to get these homes adequately insulated without any extreme renovations. This material can be blown-in from either the inside of the outside, and in many cases it’s utilized to insulate the attic. With its boric acid coating, it is a fire resistant material. It also helps with noise reduction, great pest control, and discourages mold growth. We’re committed to providing you with sustainable insulation solutions.
