I keep stacking projects up, but I really need to address this one sometime this year.

I have three entry doors that are not ideal.

Front door:  It’s solid original 1930 construction. I’ve tried, it’s not caving in from a kick attack. Problem is,  it’s of an old lock design (easily picked) and I don’t even have a key. Problem #2, it leaks air around all four sides and the wood is not blocking the single digit cold weather from radiating in.

Side door was replaced at some point. It’s got a pine frame and glass next to the deadbolt. No question I could kick it in. It’s also uninsulated.

Garage door:  It’s from 2017, but same as the side door but with less glass. Kicking it in won’t be a challenge, even though I did reinforce the frame at the dead bolt a little. Uninsulated.

I really want a level IIA door on the front, but I need something better now, not when I can afford such fancy things.

Needs to be hard to kick in (I live in the hood), needs to have minimal glass (or none for the front door), needs to be at least not conducting cold.

What is out there?

What about adding a storm door outside the existing door (look on Home Depot etc,  LINK some are made with burglar bars some places ) and installing a single cylinder Medico deadbolt and better strike plate LINK Add some weather stripping to control air leaks.  
You can always screw expanded steel or aluminum over the window in the side door to slow them down.  Make sure the hinges are not on the outside if they are then pin them by drilling both sides install a nail with the head cut off so that it prevents a closed door from lifting off the hinge.

Some burglars don't like to break glass it cuts you and makes noise and is very noticeable in front,  on the sides and in back it's more concern.

I have security doors on the house doors (the wrought iron type), but a chain and a pickup truck can yank those off.

City code won’t let me add new ones, so the garage is out on it’s own.

All doors swing in, countering the pin attack method (which is an easy way to open doors).

I was gonna replace the front security door with the impact glass version. Can’t chain to it easily.

I was going to switch to Mul-T or Protec2 locks with the new doors.

I to have an almost similar issue

Did you fabricate them brackets yourself?  Any dimensions if someone wants to make them theirselves?

What are they called if you dont mind me asking?
