COMPANY OVERVIEW
In 1974, Chem-Pruf founder William V. Pitt designed, engineered and built the first successful industrial fiberglass door that would not bow, rack or warp. This remarkable door was made possible by a unique, now patented, one-piece fiberglass stile and rail system. Tough, corrosion-resistant fiberglass door plates which form the faces of the door were permanently bonded to the stile and rail to create the finished corrosion resistant door. With an idea, a feat of engineering and a wealth of manufacturing know-how, Bill Pitt founded not only Chem-Pruf Door Company but an entire industry.
Chem-Pruf continues to set the standards with industry "firsts":

All Storm Door models meet or exceed the standards set for large missile impact (ASTM-E1886/1996 missile level D), both positive and negative cycle pressure and wind load. From hotels along the beach to offshore oil platform to public facilities to marine transportation manufacturing Chem-Pruf has a fiberglass door that is designed to withstand the harsh weather that storms can bring. When required 90 minute UL label for fire rating is available.
Ballistic Doors
Chem-Pruf Ballistic Doors have successfully completed the test protocols in accordance with UL 752 and conform to UL752 "Standard for Safety and Bullet Resisting Equipment". Chem-Pruf's ballistic door models meet and exceed the standards set for large missile impact (ASTM-E1886/1996 missile level D), ballistic resistant protective materials (NIJ-STD-0108.01), and heat transfer properites of materials (ASTM C 518), and mechanical properties of fasteners (ASTM D1761).
Blast Doors
Chem-Pruf Blast Doors are designed to protect personnel and property from explosions and explosion borne missiles. Some applications include chemical, paint or hazardous material storage rooms, pharmaceutical facilities, bioscience and nanotechnology research buildings, nuclear power stations, ammunition depots and arsenal storage facilities. Chem-Pruf Blast Doors meet and exceed industry standard for Blast Proof Doors including AAMA, 920-03 specification for operating cycle performance of side-hinged exterior door systems, ANSI A250.4-2001 test procedure and acceptance criteria for physical endurance for steel doors, frames, frame anchors and hardware reinforcements, and NWWDA TM-7 test method to determine the physical endurance of wood doors and associated hardware under accelerated operating conditions. Please see certifications for a complete list.
FEMA Doors
Tornadoes, hurricanes and other violent weather can produce winds in excess of 250mph, turning items like cars and trees into deadly projectiles. Chem-Pruf's FEMA door can withstand these forces and have been tested and labeled in accordance with FEMA 320 / ICC 500 requirements for above ground storm shelters for design and construction. FEMA 320 states that swinging door assemblies should resist a static pressure of 1.37-psi for a 5-second period. The tornado test criterion uses a 3 impacts of 15-lb. 2"x4" wood board traveling horizontally at 100-mph, which corresponds to a 250-mph wind. The ICC-500 requirement states that the pressure test load should include a safety factor of 1.2. This pressure relates to a 250 mph ground speed tornado and the door installed in Zones 4&5 per ASCE 7-05 for a corner zone with the negative pressures being greater than the positive pressures.

Door Windows
The Chem-Pruf FRP (fiberglass) window frame systems are the finest in the industry. Our gelcoated, molded resin-transfer system produces a frame of unmatched quality and corrosion resistance. The 25 mil gelcoat finish molds the color into the frame. It never needs painting and is virtually maintenance-free. Frames can be manufactured to any specification and are available in a wide variety of styles.
Door Louvers
Chem-Pruf offers custom sized and colored inverted V louvers to be used in doors that best suit your application and air flow needs. Screens can be mounted to prevent bugs and other unwanted debris from entering. Chem-Pruf inverted V louvers are of flush construction. The gel coat layer is integrally molded as the part is made, and is the primary barrier against environmental and chemical attack. Pultruded glass products do not have the molded-in gel coat protective barrier. Resin transfer of the louver vanes ensures uniformity in color and size.
Door Sweeps
hem-pruf FRP accessories are designed and manufactured to complement all Chem-Pruf FRP doors and frames. FRP thresholds, astragals, and sweeps are also available in matching colors to complete your fiberglass door system for protection against corrosive environments.

{{this.show}} {{this.hide}} FRP Wall Windows
Style 5 Wall Window - Standard
Chem-Pruf has numerous wall window frames to choose from that will enhance the look of a wall window. These frames were engineered to be as corrosion resistant as can be made, and strong enough to survive far beyond that of any wall window frame made today. Our frames have a 25-mils gel coat as the outer surface, which is molded in. This provides the maximum corrosion resistance possible. Chem-Pruf wall window frames use various types of inorganic cores to reduce weight and provide structural rigidity. Chem-Pruf wall window frames are manufactured by resin transfer molding in closed rigid molds assuring uniformity in color and size. The wall window units are assembled at Chem-Pruf to assure that the unit is ready for installation upon receipt. When it comes to choosing colors for wall window frames, architects and engineers can select any of Chem-Pruf's standard colors, or the color can be custom matched. This is an advantage over standard aluminum window frames, which come in only a few colors. Chem-Pruf's gel coat finish is molded in at the time of manufacture. It is permanent, and about half the cost of paint and field painting. The gel coat finish is the first line of defense against chemical attack and is very cost effective. In comparison to painted type windows, which can be high maintenance and expensive, Chem-Pruf®'s gel coated products require minimal maintenance, and will never need painting. Below are three types of Wall Windows we have available:
STYLE 5 WALL WINDOW - STANDARD
Chem-Pruf's Style 5 Wall Window is a 1 1/4 inch profile, 5 3/4 inch wide single rabbet fixed window frame with a drainable stop. The drainable stop prevents buildup of dirt or trash on the sill.

Wall louvers
Corrosion-Resistant FRP Louvers
The perfect solution to a corrosive environment, Chem-Pruf FRP wall louvers provide years of low-maintenance, corrosion-resistant service. All parts - jambs, headers, sills, slats and vanes - are manufactured from gel-coated, fiberglass-reinforced polymers (FRP). Resins are tailored for the exact conditions where the louvers will be installed.
Louers are of a flush constructions, with a gelcoated outer surface of approximately 25 mills (equal to 50-60 coats of paint). The gelcoat is molded into the laminate and utilizes the same resin chemistry used in the glass resin substrate. Gelcoat serves as the primary barrier against corrosive attack and can be formulated in a wide variety of colors.
In the fabrication process, following the gelcoating, an envelope consisting of 2 ounces of continuous-strand fiberglass is infused with resin to form a completely solid, corrosion -resistant part. Bosses for securing and positioning the slats or vanes are integrally molded at one time as the jambs are formed.
All reinforcing resins contain halogenated additive or coreactants plus anitomy trioxide. Resins yield a flame spread of 25 or less per ASTM E-84 and are self-extinguishing per ASTM D-635. The use of ATH (hydrated aluminum powder) to lower smoke propagation and suppress ignitability is frequently used.

Textures and Finishes
Chem-Pruf uses only the highest quality gelcoat in the manufacture of our fiberglass products with 25 mil of the specified color integrally molded in as the part is made. The gelcoat is cured within a temperature range of 120oF to 170oF creating an impermeable outer surface, uniform color throughout and a permanent homogeneous bond with the resin/fiberglass substrate beneath. This superior finish offers the first line of defense against environmental and chemical attack.
