R19 insulation is 6.25 inches thick. This type of insulation is typically made from fiberglass and is designed to provide substantial thermal resistance, with an R-value of 19. It is commonly used in residential and commercial buildings to enhance energy efficiency and comfort.
Asbestos insulation is usually greyish-brown or silver-gold and has a pebble-like appearance, making it tricky to differentiate from cellulose insulation.
To cut fiberglass insulation, use a sharp utility knife and a straightedge to ensure a clean, straight cut.
