These fibers create air pockets that trap heat, preventing its transfer. Unlike other insulation materials, fiberglass does not settle or compress over time, meaning it retains its original thickness and maintains its R value.<\/p>\n<p>The performance of fiberglass insulation is consistent over its lifetime, giving homeowners and property owners peace of mind knowing that their investment in insulation will continue to provide energy savings and comfort for many years to come.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Related_FAQs\"><\/span>Related FAQs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"1_How_does_fiberglass_insulation_work\"><\/span>1.
