Attic Insulation Photo Album: Uncomfortable Attic In Hurricane, WV.
This photo shows an attic space insulated with aging fiberglass insulation spread across the attic floor. The insulation appears unevenly distributed and compressed in several areas, which can reduce its effectiveness and allow heat to escape during the winter and enter during the summer. The exposed roof decking and framing members indicate a traditionally vented attic design, where air movement through the attic can impact overall home comfort and energy efficiency. Areas of settled insulation and gaps in coverage may contribute to temperature fluctuations, drafts, and higher heating and cooling costs.
The thing is, 85% of homes attic insulation looks like this, and the homeowner doesn't know.
