Damaging Weather Sweeping through Hawaii


This weekend will bring damaging winds and heavy rain to the coast of Hawaii. As Hurricane Iselle drew near the coast of Hawaii’s Big Island, it was downgraded to a tropical storm. Being the first tropical storm to hit the state in 22 years, Iselle brought only strong winds and a large amount of rain fall. Precautionary methods were taken for impact and citizens prepared themselves for the worst possible outcome. Many flights were closed during the harsh weather and local grocery stores are full of customers looking to stock up on necessities.

These types of storms leave damaging conditions, power outages, and high gusting winds and debris. With 65 mph winds, Iselle lowered itself from a hurricane to a tropical storm. This time of the year can be a tough time for certain parts of the country especially in coastal conditions.

Chem-Pruf has a product specifically designed for the damaging conditions one would find in a Hurricane. Our Hurricane/FBC rated storm doors have received Florida Building Code (FBC), IBC and Texas Dept. of Insurance (TDI) approval for installation in high wind coastal conditions as well as 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. Along with certification for Large missile impact (TAS 201), Uniform static air pressure (TAS 202), and Cycle wind pressure load (TAS 203), our doors will provide years of corrosion-resistant service and will withstand corrosive salt air.

Chem-Pruf fiberglass doors are designed to be installed in the worst atmospheric conditions. From coastal applications to Wastewater Treatment Facilities to Pharmaceutical Manufacturing Facilities, our doors are able to hold up against harsh environments. Rust is never an issue with fiberglass doors. Along with our profound quality, we offer a lifetime guarantee against failure due to corrosion. So if your facility is on the coast or in an area with high wind conditions, check out our Hurricane/FBC rated door.

The Choice for a Green Tomorrow

There was an interesting article in an earlier issue this year of Building Design and Construction magazine that discussed the top green movements in the modern industry. The article was by senior editor Julie S. Higginbotham and she was able to layout some great new ways companies are making the switch to more environment friendly features. She goes on to explain how the green building movement in North America will continue to grow and is showing no sign of slowing down.

Chem-Pruf is committed to protecting the environment and to preserving resources by producing products with long service lives and minimal or no upkeep requirements – and that includes no need ever to paint, eliminating possible adverse environmental impact from that activity. Chem-Pruf fiberglass doors have a lifetime guarantee against corrosion, so unlike hollow metal doors, Chem-Pruf doors rarely if ever reach landfills. Plus, Chem-Pruf doors come in a variety of colors and finishes. Below are some of the finishes that are available.

Do you know why you should choose Fiberglass Doors over Hollow Metal Doors for Corrosive Environments?

Hollow metal doors and frames have limitations in high-use, heavy-duty or corrosive environments. In these types of environments they rust, dent and deteriorate. They have so many maintenance issues that their lifespan is considerably shortened. It is a well-known fact that moisture is the enemy of every hollow metal door. Hollow metal doors have a welded design, the seams are visible and have a potential for a gap. The interior of the door will trap the moisture, permitting the door to rust from the inside out. Typically, a hollow metal door will begin to rust the day after they are manufactured. Therefore, metal doors must be painted after installation and the paint needs to be maintained year after year (or sooner in some cases). If the door is not painted on a regular basis the doors will deteriorate. Plus the interior of the door can harbor dust, dirt and bacteria.

Fiberglass doors are the only choice when corrosion is a concern. Fiberglass doors do not break down or corrode the way hollow metal doors do when exposed to water, corrosive materials or heavy usage. Chem-Pruf fiberglass doors are chemically welded assemblies, they have a monolithic design so there are no seams, gaps or cavities for bacteria or dirt to enter the interior of the door. FRP doors are manufactured with a permanent gel-coat finish, they provide a high degree of quality, consistency and reliability and the panel is virtually maintenance free.

Fiberglass door cores are typically electrically non-conductive and therefore eliminate galvanic corrosion, including concerns connected with coastal environments. They can also be appropriate for indoor water exposure in buildings such as car washes or facilities that require regular wash-downs. Do you know where else a fiberglass door should be used?

How to Maintain a Fiberglass Door

The beauty of maintaining a fiberglass door and frame is essentially non-existent. Why you ask, because our fiberglass door is highly corrosion resistant and it’s structural integrity and light weight characteristics contribute greatly to its low maintenance. Maintenance for the most part is associated with the accessories and hardware attached to the door and frame. Brown Fiberglass Doors

The door should always swing freely and smoothly, so it is important to check all hinges for loose attaching screws, hinge pin wear or other notable defects. Service the hinges or remove defective parts and replace per the hinge manufacturer’s recommendations. Check all latch-sets for loose attaching screws, latch wear or other notable defects. Self-latching devices should always function freely and smoothly as the door swings into the closed position. Silencers should be replaced when latch operation is compromised by wear. The strike should be firmly attached to the frame or inactive leaf of a pair of doors. Check for loose screws and or other notable defects. Service or remove and replace per the manufacturer’s instructions. Check all overhead devices for loose attaching screws, linkage arm, pin wear, fluid leaks, or other notable defects. The primary and secondary closing speed adjustments should also be set and maintained per the manufacturer’s instructions. The device should allow the door to operate freely and smoothly throughout its entire swing range and positively latch, when so equipped, or remain in the closed position.

A general visual inspection of the door and frame finish should be periodically conducted. Excessive surface defects should be sealed or repaired. Periodically check the interior and exterior of the door for damage. If the surface is punctured, a patch may be applied to effectively seal the door. The exterior may be maintained with an occasional non-abrasive application of wax similar to what you would use on an automobile or fiberglass boat. Chemical spills and splashes should be cleaned in a timely manner to protect the finish from fading or discoloration. Graffiti may be cleaned using non-abrasive non solvent based cleaners suitable for fiberglass gel coat surfaces. Visually inspect the gasket or weather-stripped areas such as perimeter seals, threshold seals, door bottoms etc. Inspect for signs of deterioration such as splitting, cracking, or deforming of flexible components.

The windows should be checked for cracks and or missing pieces. The lite kit mounting frame should be checked to assure all attaching screws or other means are tight, and the unit is securely attached to the door. Service the window or remove defective parts when required.

For more information on how to maintain a fiberglass door please consult the factory, your maintenance manual and you’re the manufacturer’s hardware manual.


Why are Fiberglass Doors better than Steel?

Steel doors have been commonplace for many years, and often are specified by architects and designers as the “standard” for commercial building service doors. Unfortunately, while they are economical, galvanized steel doors have their share of problems over their lifetime, including rusting and corrosion, maintenance needs such as painting, unsightly dents that cannot be removed, and fairly short, limited warranties. This begs the question: isn’t there something better? As it turns out, fiberglass doors are a much better solution. They offer the same look and functionality as a steel door while eliminating many of their concerns. For example, fiberglass doors…

  • Are Highly Resistant to Damage: Fiberglass is extremely strong and will not dent. Chem-Pruf doors are the strongest available in the industry, and will withstand the impact of 2′ x 4’s as specified in the Florida Building Code “Large Missile Impact Test”! This strength provides for a much better appearance throughout the years and improved occupant protection.

  • Are Durable: Fiberglass doesn’t corrode, and is therefore better suited for highly corrosive environments, coastal areas, and frequent exposure to harsh cleaning chemicals. Chem-Pruf doors will NEVER rust and our manufacturing method creates a completely sealed door, which provides the highest long-term structural integrity. This is extremely important if you need a wind load or fire rated door. Since steel doors corrode from the inside out, once you see rust on a steel door it is already structurally compromised and may not provide the level of protection it was purchased for.  Since Chem-Pruf FRP doors will not rust or rot, your certification remains intact throughout the life of the door.

Fiberglass or Steel

  • Require Less Maintenance: Fiberglass doors typically have a post-applied gel-coat color, which is more durable than the paint on a steel door. Chem-Pruf doors are the only doors to have an integrally molded-in gel-coat, not a post-applied one. This finish method is far stronger than a post-applied finish and can easily withstand corrosive environments and frequent cleaning with harsh chemicals while retaining it’s beautiful finish for life. A Chem-Pruf door will never need painting, significantly reducing maintenance costs. In fact, they are so durable that we warranty our doors for life!
  • Offer Custom Sizing: Unlike many steel doors, Fiberglass doors can be made to almost any dimension. Chem-Pruf does a lot of custom fitting and will work with you to design the perfect-fitting door for your facility. Bring us your toughest challenge!
  • Offer Better Long-Term Value: While they may have a higher initial cost, Fiberglass doors are an investment that lasts. Chem-Pruf doors are built to be so durable that they are warrantied for life against corrosion. This is a huge value in food processing or drug manufacturing environments needing to meet FDA requirements. If your steel door is starting to rust, it won’t pass an FDA inspection, leading to down time and unexpected costs. By installing a Chem-Pruf door you will save yourself the cost of frequent painting and replacement of corroded doors. Over 25 or more years, these become a significant cost!

Do yourself a favor and look to Chem-Pruf the next time you’re specifying or replacing a metal service door. We take great pride in building the best fiberglass doors on the market that will serve you well for years to come.
