Wall structure for protection from ballistic projectiles

A method of constructing a wall system, comprising:

• erecting a plurality of vertical support members between a lower horizontal member and an upper horizontal member to form wall frame having a first side and a second side;
• mounting a first panel on a first side of the wall frame and mounting a second panel on a second side of the wall frame to form a plurality of cavities therebetween, at least one of the first panel and the second panel comprising a sheet of construction material and a sheet of metal adhered to the sheet of construction material;
• and
• filing the cavities with a granular filler material such that the granular filler material extends from the lower horizontal member to a level proximate the upper horizontal member.

• filing the cavity with a granular filler material.

A wall section comprising:

• a lower horizontal member;
• at least a first vertical member and a second vertical member, each vertical member comprising:
• a lower end mounted on the lower horizontal member;
• an upper end;
• a first side;
• and
• a second side;
• an upper horizontal member mounted on the upper end of the first vertical member and the upper end of the second vertical member;
• a first panel secured to the first side of the first vertical member and to the first side of the second vertical member, and a second panel secured to the second side of the first vertical member and to the second side of the second vertical member, the first panel and the second panel forming a cavity bounded by the lower horizontal member, the upper horizontal member, the first vertical member and the second vertical member, at least one of the first panel and the second panel comprising:
• a wallboard sheet;
• and
• a thin sheet of high-strength material attached to and covering at least one side of the wallboard sheet;
• and
• a granular filler material that substantially fills the cavity between the lower horizontal member and the upper horizontal member.
