Pinch-resistant garage doors feature a design that pushes fingers out of harm's way should they accidentally be set too close to a closing door. Tamper resistant bottom brackets moderate the chance of harm from garage door components under tension. The polyurethane insulation even provides better fire safety because this type of insulation lowers the number of smoke and fires in case of the fire. The thermal property of insulation is expressed as an R-value. A higher R-value reduces external noise and enables the door function more softly. Many Insultated Doors are constructed using polystyrene or polyurethane foam.
