Happy Labor Day from Chem-Pruf!

This upcoming weekend will mark the end of August, the end of summer vacation for students, and the winding down of a season. The first Monday of every September is always recognized as Labor Day and dedicated to the American workers that help this nation succeed and prosper. The weekend is usually celebrated with parades, grill outs, fireworks, and the last of summer festivities. In fact, did you know that the first Labor Day parade was actually on a Tuesday? The date was September 5th, 1882 and even though parade activities were in swing, the celebration was actually a protest march for safer working conditions, shorter hours and better wages. Though the night did end up being a larger celebration with dancing and evening fireworks, much like the fun and exciting celebrations we all know and love today.

Many Labor Day gatherings will take place at local parks and recreation facilities. With warm weather, food on the grill and great music,  public parks will be filled with families and friends enjoying the time off and relaxation. If you’re at a park this weekend you might just see a Chem-Pruf door. After all Chem-Pruf doors are commonly used in parks and recreational facilities because they maintain a level of decorum that is second to none and they hold up against harsh weather, chemicals and animal waste. Plus they never need to be painted and they are graffiti resistant.

So enjoy your Labor Day this upcoming Monday, and if you are going to be attending any cookouts or festivals, be sure to keep your eye out for a Chem-Pruf fiberglass door! Whatever your application, we have the perfect door for you!

FRP Doors for Hospitals and State Facilities

The CDC released data in March showing that 1 in 25 hospital patients in the U.S. is at risk of developing a healthcare-associated infection, and an estimated 721,800 occur annually. The most common infections are pneumonia, diarrhea and urinary tract infections. The sad truth of the matter is that hospitals are full of germs, and patients invariably pass infections on to each other – if not directly, then through the hospital staff with whom they come into contact. Patients can also contract infections from bacterial that live on devises. Frequent hand washing is essential and the basic foundation of all safe care. The CDC recommends hand sanitizers that contain at least 60% alcohol for use in hospitals.

Chem-Pruf fiberglass door has a finish that is impermeable against the daily contact of alcohol based hand sanitizers, thus making Chem-Pruf doors the ideal choice for Hospitals and State Facilities. Chem-Pruf’s fiberglass door is completely seamless, eliminating cracks, seams and gaps where bacteria can hide. This tough, hygienic door can stand up to daily washdowns and rigorous cleanings with harsh chemicals including: Clidox, Quatricide, Spor-Klenz and Chlorate.

Happy 4th of July from Chem-Pruf!

July 4th

July 4th marks our nation’s birth and a day that was declared for peace and freedom. As we gather with our family and friends, we can’t help but remember what this great nation stands for and its history of independence. This one day is set aside to enjoy with loved ones and spend time in the great outdoors. So as people get ready for their holiday plans, let’s all take a moment to remember our greatest July 4th memories and what make them special to us!

For my family, the 4th of July has always been a day of cooking out, spending time with relatives, and then gathering for the fireworks display. One of the greatest 4th of July celebrations I can remember was when I was a young child and my family decided to call every relative from out of town to come celebrate the day with us. There were a great amount of people having fun and enjoying the company of others, which is one thing this great holiday should have. Throughout the celebration I can remember the delicious scent of charcoal being burned on a grill and the sound of our favorite music coming from the family radio. Then after a wonderful dinner with the people I love, we all sat around a fire to roast some decadent s’mores and continue the celebration with the sun down. This most certainly was one of my greatest memories and something I think of every time Independence Day comes around.

So if you are spending time with your family this upcoming holiday, try to think of your greatest and most special memory. Maybe it’s spending the day with distant relatives or watching your local sports with friends, or maybe it’s enjoying all the delicious cuisine that fills our homes. Whatever your special celebration may be, Chem-Pruf wants you to enjoy the day and have a happy 4th of July!


Let the Sun Shine Down

In two days summer will officially be here! The flowers are blooming, the birds are chirping and the temperature is rising, so get out of the house and have some fun. To me, there is nothing that says summer is here other than spending an afternoon with friends and family at a park enjoying the fresh warm air. Especially with the temperature changing and also the weather.

I’m a little bit of a door geek, everywhere I go I try to see if our fiberglass doors are being used. The last time I was at my local park, I noticed how structured and intact the facility buildings were and thought about the conditions they endure throughout the year; snow, the beating sun and thunderstorms. The doors on these facilities are constantly being touched, swung open and slammed shut. Chem-Pruf fiberglass door systems incorporate premium materials, superior design and engineering processes to ensure every Chem-Pruf door can withstand harsh weather, nature and human beings. In fact, Chem-Pruf door systems are designed for these applications and will perform flawlessly and remain beautiful year after year. Plus, Chem-Pruf fiberglass doors are naturally friendly to the environment; longevity, cleanliness, strength and stability make it a sound choice for a “green tomorrow” and beyond.
