Many homes feel uncomfortable in certain rooms because attics and crawl spaces act like open pathways for heat loss and heat gain. Working with an insulation company like First Defense Insulation can help by planning insulation upgrades and sealing drafts and leaks. Home insulation is often one of the most important upgrades because the attic affects how hard HVAC systems have to work. Spray foam insulation may be recommended depending on ventilation, existing insulation and comfort issues. Attic insulation can help support a tighter building envelope when installed correctly. In many cases, duct sealing should be considered along with insulation because gaps around penetrations and top plates can bypass insulation. Garage insulation can also play a role, especially when rooms over garages are uncomfortable. For older homes, insulation upgrades for older homes may be needed when insulation is dirty, damaged or compacted. A clear plan can include equipment choices that improve HVAC efficiency improvement and year-round temperature control. First Defense Insulation focuses on straightforward planning, correct materials and clean workmanship so each project supports a stronger building envelope and fewer drafts.
