Installing security doors is quite simple, and you can DIY. You must know the proper steps and avoid doing rework. 

Step 1- Take the Right Measurement.

The first and necessary step of buying a new screen door is to measure your doorway frame correctly. Security screen doors are available in multiple sizes, color options, designs, and types. 

If required, you may also consult a professional to be sure before making any significant changes. To fit your home door and serve the purpose, the security door must be the right size and style. 

Step 2- Follow the Instructions

Never skip this step. If you are doing it yourself, make sure you go through the manufacturer’s instructions very carefully before installing the door. 

To make installation more manageable, you can separate all the screws and keep them divided according to the type of door and places where it will fit in the door. 

Step 3- Install the Locks, Handles, And Hinges.

According to most door installations, you will have to attach both backing plates onto your door after you have taken the right measurement of where to install the lock and handles. 

Post this, and you must attach the inside handle and the locking lever to the internal backing plate. You can now attach the backing plate and handle assembly onto the lock body.

Types of Security Doors

There are a variety of security doors that function differently. Let’s find out what are the most popular types. 

Inswing or Outswing

The most common security doors amongst residential complexes are the inswing doors. However, they are not as secure as the outswing doors. The outswing doors are more airtight and durable. 

In most areas, the structure of the building determines whether you can install an inswing or an outswing door.  

Openwork or Screen Security Doors

The openwork security door is also considered a screen door, mostly installed right in front of any entry or exit door. It is a secure system, but it’s unlike a true security door

The openwork security doors are usually made of an aluminum frame or decorative steel and grille with a layer of inlaid tempered glass. It gives out a look that is similar to the wrought iron or glass door. 

Reinforced Security Door

To add extra security to the door, the interior of the doors must be reinforced with either aluminum or steel. This will prevent it from being kicked open or bent. 

The exception to this is a solid wood security door that does not need any interior reinforcement, as the hardwood adds extra strength and prevents it from pushed open. 

Prehung Security Door 

Most security doors are sold prehung as the framework is an essential component to the door’s security. Most security doors don’t have a wood frame but instead have a frame made of aluminum or steel. As these security doors come prehung, they contain the necessary security hinges. 

Steel security doors are also available in slab form, and they do not come with hinges or frames. You can replace a damaged security door with the security door slab, and do not worry about the frame as that is already intact.
