BLOWN-IN INSULATION IN WOODLAND HILLS, CA

The heat profile of Woodland Hills is more extreme than nearly anywhere else in Los Angeles. The neighborhood regularly records temperatures 10 to 15 degrees above those in coastal areas and the eastern Valley on the same day, and that difference persists through the night because the terrain traps heat. An attic in Woodland Hills on a hot July afternoon may be 30 to 40 degrees hotter than an attic in the same climate zone closer to the coast. The insulation in that attic needs to perform at the upper end of what Climate Zone 9 demands.

The 1960s and 1970s suburban construction that built out most of Woodland Hills used fiberglass batt insulation installed to the standards of its era. Those standards were a fraction of current recommendations. The batts that are still in place in attics from that period have been compressing and shifting for decades. Blown-in insulation over a properly prepared attic floor restores uniform, full-depth coverage and adds the R-value these homes need to perform in today’s climate.

Blown-in also has a specific advantage in homes where attic access has been disturbed by renovation work. Every HVAC replacement, electrical upgrade, or plumbing repair that requires attic access creates the potential for displacement of existing batt insulation. Blown-in material is more forgiving of disturbance and easier to restore to full coverage after work is completed.
