Get Started

Stonehenge focusses on a whole-home energy evaluation to make recommendations on how you can improve the building envelope of your upstate New York home. The building envelope is the basement floor and walls, the above grade walls, doors and windows, and the ceiling or roof. It’s what you depend on to keep you sheltered from the weather and temperature extremes.

Many contractors focus on improving only the insulation value of your home, but that’s not the only part of that needs improving. A crucial step to improving home comfort is air sealing, which gets rid of cold drafts and heat loss through air leakage.

Insulation Is Not “One Size Fits All”

All insulation has an ‘R-value’ which indicates how much resistance it has to heat flow. The higher the R-value, the better the material is at resisting heat flow.

All insulation does one thing very well: it slows the rate at which heat moves from a warm side to a cold side. Some insulations also do a good job of being an air barrier or a vapor barrier. Others also provide great sound insulation.

Insulation comes in several forms:

  • Fibrous insulation (fiberglass, cellulose or mineral wool) can be in batts, loose fill or blown in blankets.

  • Foam insulation (expanded or extruded polystyrene and polyurethane, to name the most common) comes in boards or spray foam.

Different insulation types suit different applications, below grade floors or walls, above grade walls and exposed floors, flat attics or sloped ceilings.

The Right Insulation Has to Be Installed Properly

At Stonehenge, when we specify a type of insulation, we know it will be the right one for your home’s needs. Attic insulation has to perform well under very different circumstances than interior insulation on your basement walls, for example.

For existing homes, our comprehensive energy evaluation will determine the best insulation levels so you can take advantage of the Home Performance with ENERGY STAR program. For new homes, the insulation levels will meet code compliance or ENERGY STAR certification requirements for your New York climate zone.

Once we have finished our energy analysis on your new or existing home, we work closely with our team of expert Insulation contractors to ensure that the installation is done properly.
