How durable are vinyl windows? Are they strong?
Vinyl windows are very durable. There are tens of millions of vinyl windows installed in homes and commercial buildings across the country and around the world. In the United States, some vinyl windows have been installed as long as 25 years and are still working well. Many modern designs have superior wind load ratings to wood and metal windows.

Is the vinyl in your products just the same as everyone else’s?
No. Not all vinyl (PVC) window products are alike! Nor are all window and door vinyl extrusions/formulas equal, either. Chelsea’s advanced formula and proprietary compounds represent the best in vinyl products. Other ordinary PVC products may skimp on ingredients or use low-quality additives or formulations to deliver a low price vinyl. Unfortunately, this also tends to deliver a lower quality vinyl product that does not perform well over time. At Chelsea, our total quality management program and our statistical process control program ensures every segment of the product and manufacturing are right. Always insist on the quality of products made from Chelsea.

Can I paint my vinyl windows?
There are paints specifically made for use on vinyl. Consult your local paint supplier for the proper paint and surface preparation. It is important that you follow the paint manufacturers instructions.

Will vinyl windows melt in the hot sun?
No. Vinyl windows perform well in desert climates, like those of the southwestern U.S., where daytime temperatures can reach 125°F and surfaces in the direct sun can be heated above 165°F. It’s the multi-chambered design of vinyl products that help them handle excessive levels of heat. Vinyl is an excellent insulator. It does not conduct heat readily like aluminum and the hollow chambers in a vinyl frame reduce conduction even further. So while the outside surface of a vinyl window or door frame may get hot in direct sunht, the interior walls will experience limited heat buildup.

Why are vinyl frames hollow? Why aren’t they solid?
Vinyl frames are designed with multiple chambers to provide thermal efficiency, rigidity and strength without excessive weight. A solid frame would be exceptinoally heavy, difficult to work with, expensive, and wouldn't perform as well as the multi-chambered designs in today’s window and door products.

What kind of maintenance do vinyl windows require?
Vinyl windows are virtually maintenance free, requiring no finishing upon installation and no periodic painting or sealing like wood or metal windows. They also don't rot, rust, pit or corrode like wood or metal products and aren't impacted by moisture, salt air, pollution and airborne chemicals. If they ever require cleaning, simply wiping with a damp cloth is sufficient to return them to their factory fresh condition.

What can I use if I really need to clean my vinyl windows?
Usually a few drops of mild liquid cleaner in a bucket of water is sufficient to clean any dirt or grime that may have accumulated on the window. If you have more stubborn dirt, the following household cleaners work well based on a study done by the Society of the Plastics Industry: Formula 409, Ajax Liquid Cleaner, Murphy’s Oil Soap, Lysol Cleaner, Soft Scrub, or vinegar and water. The following cleaners or types of cleaners should not be used on vinyl: Clorox, Pine Power, Ivory, Grease Relief, Tide Detergent or nail polish remover.

Do vinyl products install and handle differently?
For the most part, installation of vinyl windows, doors and other products is similar to techniques used for installing wood or metal products. There are some key differences that should be noted in the handling and storage of vinyl units. These and the proper installation steps are available from the window manufacturer.

What is vinyl (PVC)?
It is one of thousands of plastics in use today. PVC’s technical name is poly vinyl chloride. It is unique among plastics in that it is composed of nearly 60 percent chloride that stems from the rock salt sodium chloride, and about 40 percent polymers stemming from natural gas and petrochemicals.

What is fusion welding?
Many of today’s vinyl window and door products feature fusion welded corner construction. Quite simply, it is the process of mitering the corners, heating them to above 200°F and bringing the heated corners into contact until they fuse together, forming an exceptionally strong joint and a permanently sealed corner that won't leak air or water.

What about vinyl windows in a fire?
Unlike many common building materials, vinyl will not support combustion. This means they can burn if they are completely enveloped in flame, but if the flame is removed, the vinyl will self extinguish. In fact, PVC has a higher ignition temperature, lower flame spread and lower heat released in a fire than a similar sample of wood, and any smoke produced by burning PVC is of the same range as that of most organic materials.

What is virgin vinyl? Do my products have it?
Virgin vinyl is the term applied to vinyl that is extruded for the first time. Regrind is the term given to vinyl that has been extruded, then the parts are ground up into small pellets and can be re-extruded. The implication is that virgin vinyl is purer or superior to reground vinyl. As a thermo plastic, PVC can be typically reprocessed three times with little degradation to the compound. After that, additional processing uses up some of the lubricants and other additives that are used in the extrusion process. All of your frame, sashes and other major window and door parts are extruded from virgin vinyl.

What is uPVC? Do my products have it?
Yes. Your products are processed with uPVC. uPVC stands for unplasticized PVC. It is an old term brought by European extruders. Older European PVC formulas contained plasticizers to aid in extrusion of the part. These plasticizers would often migrate out of a finished product over time, leaving it brittle. This was a problem with older European PVC products. Years ago, newer technology formulas were developed that did not use or require plasticizers in rigid extrusions. In Europe, to differentiate products made with the newer formulas, they began calling them uPVC.

Are vinyl windows earth friendly?
Yes. Vinyl windows and doors are a very smart choice. Less than half of vinyl’s weight is dependent on natural resources. Vinyl windows require only one-third of the energy needed to manufacture aluminum windows. Vinyl windows also help conserve energy and reduce home heating and cooling costs. Because vinyl windows and doors do not require painting or finishing, homeowners avoid vapor emissions and disposal problems associated with frequent application of certain paints and stains.
