Insulating Your Long Island HomeWhere Should Insulation Be Installed in Your Long Island Home?

When you shore up insulating materials, you’re improving the envelope of your home. Your home’s envelope are made up of materials, systems and devices that seal off your living space from unconditioned elements outside your home. The unconditioned spaces under your roof and floor, and all other unconditioned building cavities outside your home’s envelope, should be the focus of your home insulation.

The types of insulating materials you use will depend on your preference, cost and location. You may consider other factors when choosing material types, such as sound dampening qualities that cellulose loose fill offers. Fiberglass insulating materials are practical options for attic spaces. This list outlines where to insulate and possible insulating material choices:

  • Finished attic rooms: Fiberglass fill or batts are generally used to insulate between wall studs. You should insulate floors and ceilings with unconditioned spaces located above.
  • Unconditioned attic space: Attic insulation should reach above attic joists. Fiberglass rolls and cellulose loose fill are popular choices.
  • Floor systems: Crawlspaces and basements are prone to moisture issues. So, use rigid foam board insulating materials rather than fiberglass.
  • Exterior wall cavities: All exterior walls should be insulated. You can check for insulating materials by removing outlet plates. You can also check your attic to see if wall cavities are accessible. If you’re not sure if your home’s walls are insulated to R-21, you can ask your HVAC contractor to conduct a heat gain/loss measurement using thermographic scans.
  • Windows: Efficient window treatments are important for reducing drafts and maintaining low energy bills. Practical window treatments include various types of shades, storm shutters, panels, layered draperies and blinds.
