Adequate insulation and air flow are extremely important to your air quality and utility expenditures. When it’s 115 degrees outside, it is likely 180 degrees in your attic. During the winter, a well-insulated attic, with proper ventilation, should maintain a slightly elevated temperature compared to the outside climate. Utility expenditures aside, attics are the most common place we find mold in the pacific northwest (depicted above). Additionally, attics typically have air ducts that need to be properly sealed and insulated to avoid contamination in your HVAC system and high utility costs.
