Use and Care Manual

APPLICATION
This is the most important step in your new entry system selection process. Protecting it properly can
lower maintenance, improve performance and extend the life of your new MMI DOOR entry system.
Every exterior door requires protection and there are many factors to consider such as exposure to
natural elements, color choices, storm door use and the degree of homeowner maintenance required.
All these factors must be evaluated to determine your final choice.
Door Type:
Wood doors need the most protection and will require the most maintenance depending on exposure.
Fiberglass and steel doors can tolerate more exposure but still require adequate protection.
Overhang:
In short, every exterior door—Entry, Patio or French Doors—should
have an overhang to protect the unit from natural elements, lowering
care and maintenance and extending the life of the unit. Overhangs
should extend at least four feet wider (two feet each side) than the
door unit and at least five feet out from the house. In extreme
exposures (facing south or west) or climates (desert or coastal)
overhangs should be double that size.
Inadequate overhang protection can lead to color fading, component
damage and water related issues such as warping, wood failure or
leakage. Adequate overhangs increase your choice of door types,
design, colors and specifications. They also ensure years of
dependable performance.
Colors:
The effect of natural elements, especially the sun, is generally underestimated. The face of an exterior
door can exceed 120 degrees Fahrenheit in many applications. Prolonged exposure at these
temperatures can quickly deteriorate the finish and physically damage the door.
Remember—light colors reflect heat; dark colors absorb heat. Consider sun exposure and overhang
protection when selecting a color for your door. Your choice of colors can directly affect your door’s
health. Choose wisely.
Storm Doors:
Storm doors are a double-edged sword. Yes, they can protect your new door, but in hotter climates
they can also harm an entry system quickly. The temperature behind a storm door can exceed 200
degrees Fahrenheit in many applications. Sun exposure, color choice and overhang protection should
be evaluated when considering a storm door. Make sure you evaluate thoroughly.
Please follow these guidelines to ensure years of maximum performance from your new MMI DOOR
Entry System.
