People think they’re only supposed to have to do insulation once, and it should last the life of the house.

You’ve probably heard all about replacing your windows, but never about insulation. It’s not adequate to throw fiberglass batts up in the attic – having your insulation done properly can generate a huge return for your energy savings.
Cellulose works for so many things – reducing heat loss & carbon emissions, saving money, soundproofing, keeping bugs and insects out, etc.
How flammable is your insulation? Watch this NFPA Fire Test to rate your choice.
You will see the three most common types of insulation. The first is cellulose with borate—the type Dolphin uses. When exposed to flame, it chars, then burns out.
The second type is common fiberglass® with paper backing; when it catches fire, it burns. The third type—spray foam—is the most common type of insulation; the video shows that it burns brightly.
Now which type of insulation would you specify?
Both NStar and National Grid will Rebate you 75% up to $2,000 for this work to be done. And the Federal Government will give you a tax credit of 30 % of the cost, up to $1,500. For insulation to qualify, its primary purpose must be to insulate. (example: vapor retarders are covered, insulated siding does not qualify)
