How to shield the walls and windows of a house

It is quite difficult to design a new building for high security applications; retrofitting an existing house to withstand a possible missile attack is a challenge. It is easy to conclude that placing a shield to an existing home will involve the use of high-tech materials such as Kevlar, but these materials are very expensive. Moreover, in many cases it is not necessary. The traditional building materials such as brick and stone provide excellent ballistic protection at a much lower cost, although it may require complete resurfacing of the exterior of the building.

You will need

  • Brick or stone veneer
  • Steel frames for windows
  • Bulletproof glass UL 752
  • Fiber panels bullet resistant glass (if necessary)


  1. Determines the nature of a possible threat. Before remodeling to place a shield, it is essential to define the threat to which you are defending. The materials need to withstand an attack by a gun small arms are much lower than to resist an attack from an M-14 rifle. Are you defending yourself against intruders or urban against a paramilitary terrorist threat? Make the determination and then searches for materials with a level of ballistic resistance of Underwriters Labaratories match the threat.
  2. Replace wood siding, aluminum or vinyl with a full brick or stone veneer. The stone and brick stop almost anything but Granada, and is much less expensive than other bullet-resistant materials. Furthermore, these materials provide a measure of the resistance to fire and explosion also. However, make sure you’re installing a thick material and not casting a thin veneer that looks like real stone or brick.
  3. Eliminates drywall interior wall panels and install fiber glass resistant to bullets, if remodeling the exterior of the house is impractical. Select a fiberglass panel that corresponds to your level of threat; the higher the thicker (and most expensive) the panel cost ballistic protection.
  4. Replace existing windows with bulletproof glass in steel frames. Again, the price and the thickness of bulletproof glass increases with the level of protection, so make sure you’re selecting materials that are compatible with your threat level.
  5. Replaces the windows that are required only for interior lighting with glass resistant to bullets privacy. Remember that removing a target is as important as stopping a bullet; proportions no potential aggressor you a clear view of the occupants if it’s not necessary.

Tips and Warnings

  • Consider whether the protection of the whole house is really necessary. If an attack is more likely to be done at night, for example, may be more cost effective to protect only the bedrooms of the house. If you’re protecting against invading your home, a secure vault room, steel doors can be more convenient.
  • If you need a high ballistic protection with minimal thickness ballistic steel panels are the best option. These are very expensive and difficult to install, so make sure you really need that kind of protection.
  • A bulletproof home is not necessarily a safe house. A security solution for integrated home should also involve appropriate and locks, door security cameras and alarm systems.
  • The bullet-resistant materials are designed to support only the power of the fire before they fail. No building material can provide ballistic protection without end. Replace any damaged wall or window material as soon as possible.
