A Window Opening Control Device (WOCD) is an option available for some Wincore window systems. It is designed to restrict the opening of a sash to less than 4″ to lessen the risk of accidental falls. A WOCD can be released to allow the sash to fully open for emergency escape and/or rescue. Some IRC and IBC editions have minimum sill height requirements for certain window openings, with use of a WOCD as one exception. Building codes vary by jurisdiction and is the responsibility of the contractor/installer to ensure if a WOCD is appropriate for any application.
WOCDs are effective only when properly installed and remain engaged except in cases of emergency. Installers must follow Wincore’s installation instructions and ensure occupants are familiar with and follow Wincore’s important safety information. The Wincore WOCDs have been tested for compliance with ASTM F 2090.
Wincore offers a WOCD for the following window systems:

California’s Proposition 65 entitles California consumers to special warnings for products that contain chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.We are providing the following warnings in connection with products advertised on this web site:
WARNING: This product can expose you to chemicals including titanium dioxide, which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov.
WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood.
An R-value is the measure of resistance to heat flow. The higher the R-value, the greater the resistance. U-value is the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating quality. The R-value can be obtained by dividing 1 by the U-value.
Condensation is caused by excess humidity in the home and appears on the coldest area of a wall. That is why condensation usually appears on windows.. The warmer the air, the more moisture it will retain, therefore when the air comes in contact with the colder glass, the air is cooled and moisture is released on the glass.
Use exhaust fans in your kitchen, laundry room, and bathroom. Vent gas burners and clothes dryers to the outside. Use a dehumidifier to remove excess humidity from the air in your home. Air out your home by opening your windows for at least a few minutes every day.
Yes, the vinyl can be painted. However, we definitely do not recommend it. The warranty on the vinyl becomes void if the vinyl is painted or stained, or if the surface is altered in any way.
Since vinyl does not pit, peel, or flake over time, simple care and cleaning can keep your windows looking beautiful for years to come. Heavy rains will keep the vinyl fairly clean, but you can also clean them yourself if desired. Do not use a high pressure spray to clean your vinyl windows. The pressure can damage the caulking and cause your windows to leak. Use a mild detergent and soft cloth or brush instead. For dirt and stains that are difficult to remove, please see the warranty (Replacement / New Construction).
NFRC is the National Fenestration Rating Council, a non-profit organization supported by the Department of Energy that helps consumers compare the energy performance of windows and doors. Window manufacturers that participate in the NRFC program are required to label every window with its thermal specifications. The consumer is then assured that those products meet the thermal requirements for energy efficiency set by the NFRC. Being a member of the NRFC is not required for window manufacturers due to the extensive third party inspection and product testing; however, Wincore® Windows and Doors is a participant of the NFRC program.
Energy Star® is a government program, administered by the Department of Energy and the Environmental Protection Agency, that is designed to reduce the amount of fossil fuels used in heating and cooling through the energy efficiency of windows and doors. Windows and doors will only have the Energy Star® labels if they are tested by a third party laboratory through the NFRC program and meet predetermined U-value ratings. Wincore® windows meet Energy Star® performance guidelines.
Low E glass provides year-round energy savings. A thin, transparent metallic coating is applied to the glass and filters solar radiation. During the summer, Low E reduces heat gain and keeps your home cooler. In the winter, Low E keeps your home warmer by reflecting heat back into the home.
Argon offers a higher level of insulation. The Argon is located in the middle of the insulated glass unit. For air to insulate, it needs to be as still as possible because moving air carries energy. Argon is heavier than air, so it is less likely to experience convection or thermal movement.
The performance and lasting endurance of vinyl windows compares generously to other building materials. Vinyl offers low maintenance, energy efficiency, and lower cost while still creating an aesthetic appeal. Unlike other materials, however, vinyl does not shrink, swell, or bend during harsh weather conditions.
