We now do Attic Insulation
We use the Certainteed InsulSafe Product. This Fiberglass insulation has the best combination of insulation characteristics, fire retardant, and dust retardant that we have found. It is not like the old itchy fiberglass or rockwool insulation from the past. This looks like a blanket of snow when it is installed in your attic. It does not itch and it does not create dust problems in the home like the Cellulose insulation does.
