Webster Groves Attic Insulation & Weatherization

Green Space Construction recently performed a weatherization audit on a home in Webster Groves (St. Louis, Missouri) and assessed the following issues:

• Attic knee wall spaces were poorly insulated.
• The interior walls exposed to the attic spaces had insufficient, old fiberglass batt insulation.
• The attic floor joists had a small amount of old fiberglass insulation, providing very little impact for the home's comfort.
• The exterior walls exposed to the attic spaces had exposed masonry units with many holes, gaps and cracks. These exterior walls were a main culprit of air infiltration into and out of the home.
  
• Attic spaces did not have adequate ventilation.
• Penetrations of plumbing stacks, electrical wiring and outlets, skylights, etc. were not properly sealed between the attic/exterior/floor joists and between the attic and the finished interior spaces.

As a result of this analysis, Green Space recommended and performed the following improvements:

• Remove all old fiberglass batt insulation from the interior walls exposed to the attic spaces.
• Install fiber mesh at interior wall studs, and dense pack with blown cellulose insulation.
• Install blown cellulose insulation in floor joists to a thickness of 16", providing an R-value of 30.
• Install rigid foam insulation over exposed masonry units. Sealed all air penetrations, gaps and seams with spray foam insulation.
• Installed roof turbines at each attic space, allowing for proper ventilation at each space.
• Sealed all penetration of plumbing stacks, electrical wiring and outlets, skylights, etc. between the attic/exterior/floor joists and between the attic and the finished interior spaces with spray foam insulation.
