The energy efficiency of your new windows relies heavily on the quality of the installation. Every window installation is unique and we anticipate different challenges with each job. In addition to purchasing an energy efficient window, proper installation is extremely important. When we install windows we apply flashing properly in those areas where leaks may occur. In order to protect your home from water damage, it is critical that the flashing is applied properly to those areas that are often overlooked.
Wincore® vinyl windows are simple and easy to clean which makes maintaining them looking like new easy for many years to come.
The National Fenestration Rating Council (NFRC) is a nonprofit organization that empowers consumers who are IMG_1478in the market for energy efficient windows, doors, and skylights. When you see the NFRC label on these products, this is your assurance that it’s going to perform the way it’s advertised to perform.
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 Emissivity Glass (Low E Glass)
Low E glass is glass that has thin, transparent layers of metal oxide applied to the surface. This coating allows light to pass through, while reflecting heat rays and harmful ultraviolet rays from the sun. Because the Low E coating helps to control the heat transfer through a window or door, it lowers U-value ratings and increases R-value ratings. Having windows and doors with Low E glass helps to keep your home more comfortable year round by helping to keep cool, air-conditioned air inside during warmer months and heated air inside during colder months.
Most windows manufactured today feature dual-paned glass. That means there are actually two pieces of glass, separated by a spacer for uniformity inside each sash of the window or panel of the sliding door. The spacer between the panes is sealed to each piece of glass, creating an air space between the two. Temperature fluctuations cause air molecules to move around and transfer heat from one pane of glass to the other. This is known as convection and can result in heat gain in an air-conditioned room in your home, or heat loss in a heated room in your home. To minimize convection, Argon gas can be used to replace the air inside the insulated glass unit. Argon is a colorless, odorless, non-toxic gas found in the atmosphere. Argon’s molecular structure makes it denser than air, causing it not to be affected as much by temperature fluctuations. When Argon is used to fill the insulating glass unit instead of air, it helps to reduce convection rates and thereby improves the efficiency of your window or door.
Adding to the insulating performance of the window is created by honeycombed chambers inside the vinyl profiles. The chambers make the vinyl profiles stronger, not allowing the profile to sag or lose shape over time. But more importantly, because these chambers are small and airtight, they act as tiny pockets of insulation around the window or door, thereby increasing the unit’s overall efficiency.
The uniquely designed U-channel spacer system adds to energy performance by helping to reduce temperature transference between the two panes of glass inside the insulating glass unit. With conventional box spacers, temperature transference can occur through a direct path across the top of the spacer. This is known as conduction. Because the U-channel design eliminates this direct path and forces the transfer current down and around the spacer, the current is weakened because of the additional distance it has to travel.
To keep the edges of the glass warmer, the insulating glass unit is set 1/2” deep into the vinyl of the sash. By keeping the edge of the unit warmer and better insulated against temperature fluctuations, it improves the efficiency of the unit.
