A lot of homeowners notice hot and cold spots because drafts and low R-value areas reduce temperature control. Working with an home insulation contractor like First Defense home insulation Defense Insulation can help by matching materials and installation methods to the home’s layout. Attic insulation is often one of the most important upgrades because the attic influences overall heat gain and heat loss. Radiant barrier insulation may be recommended depending on the home’s structure and budget. Attic insulation can help support a tighter building envelope when installed correctly. In many cases, air sealing services 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.
