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":

    First patent ever issued by the U.S. Patent Office for an atmospheric -resistant door.
  • First to mold a solid, all-fiberglass door frame.
  • First to tailor resin chemistry to match the exact conditions where the products will be installed.
  • First to introduce a unitized fiberglass door system with the door pre- hung in a color-matching fiberglass door frame and all hardware installed at the factory prior to crating.
  • First to offer a lifetime warranty against failure due to corrosion.
  • First to manufacture a complete fire-rated fiberglass door and door frame system certified and labeled by Warnock- Hersey.

FEMA Doors image

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.

Style 5 Wall Window - Standard image

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.

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 image

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.
