https://www.randrmagonline.com/articles/90866-mold-and-the-need-for-attic-restorationMore on Balance’s approach:
We prioritize the thoughtful alignment of a home's enclosure and mechanical systems. Balance recognizes that homes built two decades ago were designed to "breathe," allowing for natural airflow to regulate temperature and moisture levels. However, modern construction methods and materials have shifted towards creating tighter homes that are not meant to breathe in the same way.This shift presents challenges, as features like energy-efficient windows, cooler attic environments due to improved roofing materials, and encapsulated attics can inadvertently lead to increased moisture, humidity, and environments conducive to mold growth. These issues can arise when homes are not properly aligned with modern building practices, potentially resulting in discomfort, poor indoor air quality, and health hazards.
Marco's deep understanding of how homes are designed to perform allows Balance to address these challenges effectively. By identifying homes that are underperforming or straddling building codes, Balance can implement attic restorations that ensure optimal environmental control. This means creating spaces that are not only comfortable but also dry and healthy for occupants.
Through a combination of optimal insulation techniques, strategic ventilation solutions, and moisture management strategies, Balance helps achieve the perfect balance between energy efficiency and indoor environmental quality.
