Trusted Insulation Contractors in Haverhill, MA

As everyone knows, heat rises. When the lower part of your house is nice and warm because your furnace is chugging away, the warm air is wafting up, up and away, into the attic and out the roof. Experts agree that the attic is arguably the greatest single area for heat loss in the home.

Batt, blown-In, and spray foam insulation are particularly effective means of insulating walls. They save energy, reduce heating and cooling bills, control noise, and even reduce condensation and rot.

All types of insulation have their place.a. Closed cell foam is great for air sealing and R-value where there are space constraints, moisture concerns, etc. Also, closed cell foam increases the strength of the structure.b. Open cell is good at air sealing and R-value where there is enough depth to use it. Open cell is also good for sound attenuation.c. Cellulose is good where there is enough depth to reach desired R-value and is great for sound attenuation. Cellulose does not have great air sealing capability, but it will slow/resist airflow if dense packed into walls. Cellulose is even fire, mold/mildew, and rodent resistant. Cellulose is also considered one of the most environmentally-friendly types of insulation due to its embodied energy.d. Rockwool is very similar to cellulose, except it has better fire-resistant properties and moisture properties and a little bit more R-value per inch.e. Fiberglass is the last one we measure because it is the least effective. The main pros for fiberglass are that it will get you to the desired R-value, if there is enough depth, and it is inexpensive. Fiberglass does not have air sealing capabilities, and it gets ruined and grows mold easily if it gets wet. Pests love to nest in it! The kraft paper backing/vapor retarder is flammable and not supposed to be left exposed, and the fiberglass fibers are a known and measurable contaminant to the atmosphere, and thought to be a carcinogen.+

Formaldehyde is a colorless poisonous gas synthesized by the oxidation of methanol and used as an antiseptic, disinfectant, histologic fixative, and general-purpose chemical reagent for laboratory applications. The use of formaldehyde in fiberglass insulation stopped in 2015.

Unfortunately the insulation world is an unlicensed and an unregulated industry. Make sure to ask for licenses, certifications, insurance, and references when choosing an insulation company. Not only do we have our HIC, ICLS, Lead-safe and BPI licenses and certifications, we are one of the few companies in the area that can boast SPFA master installers on our team. This means they have passed extensive training and exams and have completed at least 500,000 board feet on insulation experience!
