To protect your home from cold weather, the door must be well-insulated. The most common choices are fiberglass, solid wood, metal. Make sure the frame has no leaks or gaps.
Temperature Spikes: Cold, Heat
The seal must be air-tight at all times. A storm door installed in front of the exterior one protects against hail.
Good insulation is also important in hot weather. Here, metal performs worse than wood or fiberglass, as it captures heat and gets hot. Alternatively, consider a screen door. It will allow you to open the front door and let some air inside during hot and humid days.
The term describes a special three-layer structure that prevents the transfer of heat and cold between the interior and the exterior. Doors with a thermal break contain two panels with a layer between them preventing the transfer of heat/cold.
In highly humid conditions screen doors are a great addition. You may also get a storm door for extra protection. Keep it closed when the weather is bad, and open up to the screen door when humidity is high. Metal and fiberglass will both retain shape. Wood performs poorly in general, but hardwood swells less often than the other types.
A well-insulated fiberglass door is resistant to sun damage. Metal gets hot, and wood becomes weathered. If the door gets a lot of direct sun rays, steer clear of glass (or make sure it is treated and insulated properly). Stained glass can reduce the amount of light that comes in.
These doors should be strong enough to withstand harsh weather. They should also be resistant to physical force.
Life Term and Durability
A good door will serve you for decades, but durability depends on the material. Wood, fiberglass, vinyl, and steel are the top four. Wood creates a traditional and cozy look, but it is less durable than steel or fiberglass. When the temperature fluctuates a lot, wood tends to shrink and swell.
Vinyl is more durable, and it is also UV resistant. Fiberglass doors never rust, warp, dent, or rot. They can also be insulated for severe weather conditions. Steel doors come with a wood frame with polyurethane foam inside as a thermal barrier. The quality varies greatly.
Only to Be Installed by Professionals
Front doors must only be installed by professionals. They should be hung perfectly well to guarantee insulation. An expert can also help you pick the right model.
Different materials are suited to different environments. Wood boosts the curb look, but it tends to swell and shrink in changeable weather.
Vinyl is durable. Such doors can be paired with windows in packages ensuring an aesthetic match and good performance. Fiberglass can provide the look of wood and can be painted. There is a wide range of textures.
A steel door consists of a wood frame covered or filled with a steel skin. The polyurethane foam provides insulation. The frame makes the slab stiff.
