Pinch-resistant garage doors feature a layout that pushes fingers out of harm's way should they accidentally be put too close to a shutting door. Tamper resistant bottom brackets moderate the chance of injury from garage door parts under tension. The polyurethane insulation even provides better fire safety because this sort 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 outside noise and enables the door function more quietly. Many Insultated Doors are constructed using polystyrene or polyurethane foam.
