Homes can feel uneven from one room to the next 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 identifying the biggest weak points and choosing the right insulation type. Home insulation is often one of the most important upgrades because the attic influences overall heat gain and heat loss. Spray foam insulation may be recommended depending on the home’s structure and budget. Attic insulation can help increase R-value and seal small gaps when installed correctly. In many cases, draft sealing should be considered along with insulation because unsealed pathways can make new insulation less effective. Crawl space insulation can also play a role, especially when floors feel cold, humidity is high or ducts run through unconditioned spaces. For older homes, retrofit insulation work may be needed when insulation is wet, moldy or contaminated. 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.
