Like Anything in life, the higher-priced product is usually of greater quality – garage doors are not an exception to the rule. There are a number of factors that invariably affect the price of a garage door.
The level of waterproofing will more or less have a correlation with the price of the door. Manufacturers will often have little weatherproofing on canopy/retractable doors, but roller or sectional doors will protect against the worst elements.
The amount of insulation found in a garage door can have not only a dramatic effect on the temperature of your garage but on the temperature of neighbouring rooms. The amount of insulation that a garage door provides is represented by an international measurement called the R-value.
