Advantages of Cellulose Contact

It’s not as cheap as fiberglass, but it’s much more reasonable than rigid and spray foam options.

Lowest Embodied Energy
Of all the types of insulation, cellulose takes the least energy to produce. It is recycled newspaper after all and often it is locally sourced and manufactured.

Fills all gaps
While batts will leave many gaps around electrical wires and boxes and will not always hug the studs, blown-in cellulose fills every available gap when installed properly.

Air Retarder
Air leaks in your homes walls and roof can cause significant losses in efficiency. Cellulose significantly resists the flow of air through your walls and maintains it’s rated R-value even in heavy gusts. This feature also makes cellulose a great fire retardant compared to batts.

Maintains R value
Cellulose is exceptional at maintaining its advertised R value. Fiberglass wilts in the face of wind and extreme temperature difference between inside and outside.

High thermal mass
It’s not called dense-pack for no reason. Cellulose adds thermal mass to your walls that has been proven to help a home maintain its temperature for days longer than a similar home insulated to the same R-values with fiberglass.

Energy Star

Retrofit Insulation

We offer loose fill and dense packed cellulose insulation for retrofit wall and roof applications. Long, flexible recycled paper fibers ensure void-free filling of the space to be insulated by sealing around wiring, plumbing, and other obstacles.

Reno/New Construction

Spray applied cellulose is a green alternative to foam for renovation and new construction applications. We also offer environmentally friendly fiberglass batting alternatives such as mineral wool and denim.

Flat Roof/Attic

The attic/cockloft is one of the largest sources of potential heat loss in a home and often one of the most neglected areas when it comes to insulation, especially in older brownstones & row houses.

Exterior Walls

Whether lathe & plaster or drywall, the walls of your home are arguably the most beneficial and important areas to insulate.


Insulate ceilings when you wish to acheive separate zoned heating. Floors over unheated spaces such as parking garages should always be insulated.
