Why fiberglass still makes sense in Grafton
Blown fiberglass is a clean, lightweight way to top up an attic, and it does not absorb moisture. We seal the attic floor first so the new insulation works as intended.
When older homes are opened up for renovation, fiberglass batts in the open walls, combined with air sealing, bring them much closer to new-construction performance.
Grafton is minutes from our Westborough, MA headquarters, so estimates and follow-up visits are easy to schedule.
- Pairs well with air sealing
- Code-compliant for walls, floors and attics
- Fast install for builders
- Non-combustible glass fibers
Applications
The best uses for fiberglass in Grafton
These are the fiberglass jobs builders and homeowners ask us for most in Grafton.
Attic floors
Blown fiberglass tops up attics to recommended depth after sealing.
Kneewalls
Batts with an air barrier insulate cape and bonus-room kneewalls.
Additions and renovations
Open walls and ceilings in remodels get insulated before drywall.Local homes
Grafton homes and what they need
Grafton has historic homes around Grafton Common and in villages such as North Grafton and Fisherville, plus newer subdivisions built over the last few decades.
Grafton's villages, including North Grafton, South Grafton, Fisherville, Farnumsville and Saundersville, grew around mills on the Blackstone and Quinsigamond rivers, while newer neighborhoods spread out from Grafton Common. That mix means we often see antique homes and newer colonials on the same street.
Worcester County homes heated with oil or propane often see the fastest payback from sealing air leaks, because every gallon saved is money that stays in the house.

FAQ
Fiberglass questions in Grafton, MA
Does fiberglass absorb moisture?
The glass fibers do not absorb water, but wet insulation loses performance, so leaks should be fixed first.
Fiberglass or spray foam?
Spray foam seals air as it insulates and costs more. Fiberglass costs less and works well with separate air sealing. Many projects use both.
What is blown fiberglass?
Loose fiberglass blown into attics. It is light, resists settling and covers large areas quickly.
Faced or unfaced batts?
It depends on the location and the vapor control needed. We follow code and manufacturer guidance.
Can fiberglass go in an existing wall?
Not easily. For closed walls, dense-pack cellulose is usually the better choice.
Do you install fiberglass for builders?
Yes. We quote from plans and schedule around your framing, mechanical and drywall work.
How soon can you start a fiberglass project in Grafton?
