Double Door

There are several benefits to using a double door:

Aesthetics: Double doors can add a stylish and elegant look to the entrance of a building or room.

Space-saving: Double doors take up less space when open, as they open inwards or outwards rather than swinging in just one direction. This can be especially useful in smaller spaces where a single door would swing into the room and take up valuable floor space.

Improved insulation: Double doors can provide better insulation than a single door, as there is less space for air to leak through. This can help keep a room warmer in the winter and cooler in the summer, leading to energy savings.

Increased security: Double doors can offer an additional level of security, as they are more difficult to break through than a single door.

Enhanced functionality: Double doors can be used in various settings, including as a main entrance to a home or commercial building, as a partition between rooms, or as a way to separate outdoor and indoor spaces.

Steel Double Entry Doors
Steel entryway doors are the most popular choice because they provide security, durability, and quality. Other factors that make steel doors desirable include their weather-proof characteristics and the fact that they don’t warp, rust, or become disfigured over time. Despite all the advantages of steel doors, they are relatively inexpensive compared to glass double entry doors.

Fibreglass Double Entry Doors
Fibreglass double entry doors are also quite durable and secure, making them ideal for cold Canadian winters. In fact, they’re so efficient that they require little to no maintenance. Built to last, they are typically used for exterior applications. One of the most notable benefits of fibreglass doors is that they can be manufactured in virtually any shape and texture.

Wooden Double Entry Doors
Wooden doors can create beautiful entryways, but homeowners often prefer to use them as interior doors since they require more maintenance. They can give your home a vintage appeal, especially when combined with glass panels. Additionally, they can be painted or varnished in any color.

Glass Double Entry Doors
Glass double entry doors are undoubtedly the most elegant option, adding an element of class to your home. They also allow natural light to flow into your entryway. Double entry doors can be made entirely of glass or combined with other materials in the form of glass panels.

Step 1: Using a 4' or 6' level, draw a plumb line about 1/2" from the rough opening on both sides of the wall. This will allow you to plumb, level, and square both pairs of doors together.

Step 2: Screw the EZ-Hang brackets to the back of the jambs: one under each hinge and one centered on the top. Place 1/2" blocks under both door jambs if you are installing carpet on the floor. This will allow the carpet to be tucked under the jambs while providing some vertical adjustment to match the heights of both doors.
If installing on a finished hard surface floor, check it for level and trim one side of the jambs accordingly if needed. A good tip is to place a block under both doors to hold them even and prevent sagging against each other. This block should be approximately equal to the distance from the door to the floor when measured by the hinge.

Step 3: Insert the doors and jamb into the rough opening. Starting at the top hinge, align one of the bracket lines with the level line drawn in Step 1. Screw the door to the wall using the drywall screws provided. Work your way down the side of the door, ensuring that you use the same reference line for each of the three hinge brackets.
There are two lines on the brackets; be sure to use the same line for all the brackets on the hinge side. Move over to the opposite side of the door and repeat, starting at the top again. Next, check the clearance between the frame and the doors at the top, as well as the gap between the doors themselves.
Make sure these gaps are equal. If not, slightly loosen the screws and adjust as needed to achieve an acceptable visual appearance.

Step 4: Remove the top center hinge screw and replace it with a matching color 2-1/2" long screw that will penetrate into the wall framing. Do not tweak or over-tighten this screw, as it could pull the doors apart. Stop when the screw makes contact with the hinge. This screw keeps heavy doors from sagging over time.

In the context of double doors, the metal bar running vertically between them is called a mullion. This term is commonly used in the door industry and refers to a vertical or horizontal element that separates and supports panes of glass, as well as sections of metal or wood.
A mullion is an essential component of commercial door hardware that provides structural support for large glass or metal panels. It is usually made of aluminum or steel and is designed to fit between the two doors, creating a seal to prevent air and water infiltration. The primary function of a mullion is to provide structural stability and support for the doors. It helps distribute the weight of the doors evenly and ensures that they remain in their proper position. Additionally, mullions provide a visual break between the two doors, creating a more aesthetically pleasing appearance.
Mullions are used in situations where large doors need to be divided into smaller sections. They are commonly found in commercial settings such as shopping malls, airports, and office buildings. Mullions are also used in residential settings for patio doors or large windows.
When installing a mullion, it is important to ensure that it is properly aligned and securely fastened to the doors. This will help ensure that the doors remain stable and do not sag or bow over time. It is also essential to ensure that the mullion is properly sealed to prevent air and water infiltration.

At first glance, you may think that French doors and double doors are the same type of fixture, and in many ways, they are. However, there are some differences between the two that you may not notice.
One of the main differences is the material from which they are crafted. Double doors are often made of solid wood, whereas French doors typically feature panes of glass that help flood the space with natural light.
Doors made solely from wood are not as durable or secure as those crafted from UPVC or aluminum, which means that French doors can be more secure and last longer than their wooden double door counterparts.
French doors usually open outwards into an exterior space, allowing for more room in your home and making them ideal for smaller rooms that struggle with limited space.
