Cellulose Insulation in Swanzey NH

For attics, we recommend cellulose. It’s made from recycled materials, blown in to fill the complete attic floor, and adapts well to irregular framing. The result is uniform thermal coverage throughout the entire space.

Frequently Asked Questions

What insulation do most homeowners in Swanzey NH need first - attic or basement?

It depends on the property, and that’s exactly what the initial assessment determines. Attic insulation with cellulose is often the highest-impact first step. Basement spray foam addresses air infiltration and moisture from below. At Farnum, we assess both areas and recommend where to start.
There is almost always room to improve. Efficiency Vermont and Energy Star recommend R-49 to R-60 for attics and R-15 or higher for basement walls. Many homes built in the 70s, 80s, and 90s fall short of current targets. Our team measures your actual levels and shows you exactly what the gap looks like.
Most residential insulation projects are completed in a single day. Attic cellulose and basement spray foam are efficient processes when the property has been assessed properly in advance. We confirm a realistic project timeline during the initial walkthrough.
Yes. Insulation reduces sound transmission through walls, floors, and ceilings, not just heat loss. Air sealing, which we incorporate into every project, further reduces noise infiltration from outside.
