About this file
This is a fabrication and installation instruction document from Armortex for bullet and blast resistant fiberglass products, related to a Washington County, Oregon Facilities Division contract opportunity to install transaction windows at the Law Enforcement Center. The Armortex product is a fiberglass reinforced plastic (FRP) manufactured by mechanically injecting woven roving ballistic grade fiberglass cloth with thermoset polyester resin, then pressing the impregnated material into flat rigid sheets using a hydraulic hot press. The Washington County project requires installation of two transaction windows—one for the Permits Department and one for the Civil Department—with consolidation of the Civil lobby entry to serve both departments. Work must be completed after business hours (Monday through Friday, 8 AM to 5 PM) to maintain lobby access, and background checks are required for all personnel.
The Armortex fabrication instructions detail cutting using standard carpentry tools (circular saws, table saws, panel saws, or saber saws) with specified RemGrit blade types and high-speed steel twist drills for drilling at slow speeds. Installation can be accomplished using industrial adhesive (mastic), screws, or bolts, with critical ballistic integrity requirements including 4-inch overlap strips (battens) at all seams to ensure 2-inch ballistic overlap on each side and 12-to-18-inch vertical strips for curved surfaces. The material accepts wood or plastic veneer using contact cement and can be upholstered or painted after surface preparation with sandpaper. Armortex recommends use of disposable respirators and Tyvek coveralls for prolonged cutting operations conducted in well-ventilated areas.

ARMORTEX® BULLET/BLAST RESISTANT FIBERGLASS
FABRICATION INSTRUCTIONS
PRODUCT DESCRIPTION
Armortex® Bullet Resistant Fiberglass is a fiberglass reinforced plastic (FRP). This material is manufactured by mechanically injecting woven roving ballistic grade fiberglass cloth with a thermoset polyester resin. The impregnated cloth is then placed in a hydraulic hot press and pressed into flat rigid sheets.
INSTALLATION
Cut Armortex® using ordinary carpentry tools. Circular saw, table saw, panel saw, saber saw, etc.
Use the following blades:
RemGrit® "Grit Edge"
GC 703 7" Circular
GC805 8" Circular
GC915 12" Circular
GJ18 Saber Saw
If continuous or prolonged cutting is anticipated, we recommend the use of a disposable respirator and Tyvek disposable coveralls. Always cut in a well ventilated area. Armortex® Bullet Resistant
Fiberglass may be drilled using high speed steel twist drills. Materials should be drilled at a slow speed.
Armortex® may be adhered using an industrial adhesive (mastic) and/or using screws or bolts. It is acceptable to adhere Armortex® to the front surface of the bench and cover it with a veneer. However, it is generally easier to cut appliques of Armortex® and adhere to the inside surfaces.
Any butt joints or seams create a ballistic weakness at the seam. To insure ballistic integrity, we recommend that you incorporate 4" overlap strips (battens). These strips insure a 2" ballistic overlap on each side of the seam. Conformity to curved surfaces can be handled by placing 12" to 18" vertical strips following the inside curvature of the surface to be protected. The same 4" overlap strips should be employed at each joint.
Armortex® easily accepts a wood or plastic veneer using contact cement. It may also be upholstered or painted. To paint we recommend "roughing up" the surface with sandpaper.
