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