Many homes feel uncomfortable in certain rooms because air leaks and weak insulation let conditioned air escape. Working with an insulation company like First Defense Insulation can help by planning insulation upgrades and sealing drafts and leaks. Insulation is often one of the most important upgrades because the attic influences overall heat gain and heat loss. Blown-in insulation may be recommended depending on ventilation, existing insulation and comfort issues. Spray foam insulation can help reduce drafts and improve thermal performance when installed correctly. In many cases, draft sealing should be considered along with insulation because gaps around penetrations and top plates can bypass insulation. Crawl space insulation can also play a role, especially when there are musty odors and moisture concerns. For older homes, insulation upgrades for older homes may be needed when insulation is settled and no longer performing well. A clear plan can include energy audit services and targeted upgrades. First Defense Insulation focuses on measured upgrades that improve indoor comfort and reduce energy bills so each project supports a stronger building envelope and fewer drafts.
