Fiberglass insulation remains one of the most widely used and cost-effective insulation solutions, available in various formats including pre-cut batts, rolls, and loose-fill for blown-in applications. Professional installation ensures proper handling and placement critical for performance, addressing common DIY mistakes such as compression (which reduces R-value), gaps around obstructions, and improper facing orientation that can lead to moisture problems. Our installation techniques include careful cutting around electrical boxes and plumbing, complete filling of wall cavities, and proper depth measurement in attic applications to achieve specified R-values appropriate for your climate zone. Modern fiberglass products offer improved performance over older generations, with higher density options providing better R-values (typically 3.1-4.3 per inch) and reduced air permeability, though comprehensive air sealing is still recommended as a complementary service for optimal efficiency. Beyond its favorable cost-to-performance ratio, fiberglass offers excellent fire resistance, does not settle significantly over time, and provides effective sound attenuation when properly installed, making it suitable for most residential and commercial applications.
