Question: How do I Install an EcoShield Window?
Answer: Instructions on installing EcoShield Windows can be found on our website under "Customer Service" Installation Instructions.
Question: How do I make sense of an NFRC label on EcoShield vinyl windows?
Answer: NFRC stands for National Fenestration Rating Council. The NFRC is an independent non profit organization which tests and certifies windows to certain performance ratings to help consumers compare the performance of one window with the performance of another window. The windows are tested using computer simulation and physical testing at laboratories accredited by the NFRC. The NFRC label provides the results of this testing using various standard ratings. On EcoShield vinyl replacement windows and new construction windows the NFRC label contains the U-Factor, Solar Heat Gain Coefficient, Visible Transmittance, and DP Factor. The U-Factor measures the rate at which heat transfers and is an indicator of how well a window insulates so the lower the U-Factor the better the window insulates. According to Energy Star U-factor values generally range from 0.25 to 1.25. The Solar Heat Gain Coefficient (SHGC) measures the solar energy that is transmitted through the window. This measurement is scaled from 0 to 1 and is an indicator of how well the window blocks heat that is caused by sunlight. Again, the lower the number the less solar heat is transferred through the window. According to Energy Star the SHGC values typically range from 0.25 to 0.80. The Visible Transmittance rating's range is from 0 to 1 and measures the light that is permitted through the window. The higher the Visible Transmittance value the better the window allows light to pass through it. According to Energy Star, values generally range from 0.20 to 0.80. The last value found on the NFRC label of EcoShield vinyl replacement windows and new construction windows is the DP or Design Pressure rating which tests the ability of the window to survive a certain amount of positive or negative pressure per square foot. The DP rating required for different applications varies based on many factors which will be outlined in the local building code. The higher the DP rating the better the window will stand up to design pressure criteria.
Question: How do I measure for a western blind stop storm window?
Answer: To correctly measure the width, take a measurement between the inside square edges of the outside casing at three points: head, meeting rail, and sill. Use the smallest measurement. To correctly measure the height, take a measurement from the bottom of the square edge of the top casing to the top of the sill in front of each blind stop on the jambs. Use the smallest measurement. For a drop sill, if the sill has a drop of over 3/4" specify the drop sill height on your order and indicate whether the drop sill has or has not been included in the overall height dimension.

Question: How do I measure for an eastern overlap storm window?
Answer: To correctly measure the width, take a measurement between the inside edges of the outside casing at three points: top, meeting rail and sill. Use the smallest measurement. To correctly measure the height, take a measurement from the bottom of the top casing to the sill along the face of each side casing so as to include the slope of the sill. For a drop sill, if the sill has a drop of over 3/4" specify the drop sill height on your order and indicate whether the drop sill has or has not been included in the overall height dimension.

Question: How do I tilt in my EcoShield window to clean it? Instructional Video
Answer: EcoShield single hung and double hung windows are designed for easy cleaning by tilting the sashes inward so the outside of the window can be cleaned from the inside. To tilt a window in for cleaning, first unlock the security locks on the sash. Each window comes with two tilt latches on each operating sash. Raise the bottom sash about three inches. Using both hands, disengage the tilt latches on both sides simultaneously. While holding the latches with your thumbs, gently pull the top of the sash toward you until the latches are clear of the frame. Holding the top of the sash, continue to lower it until you pass 90 degrees. This will lock the balance shoes in place. To tilt the top sash (on the double hung), lower the sash about three inches and follow the same procedures. To return either sash to its operating position, swing the sash back up and push the top of the sash gently until the tilt latches snap back in the side jambs.
Question: How do I use the ventilation lock feature?
Answer: Most EcoShield single hung and double hung windows have ventilation locks on the top sash vertical rails. Since they are spring-loaded, simply push in against the lock and slide upwards. The lock will protrude out as pressure is taken off. Once the lock has been extended, raise the bottom sash until it catches the ventilation lock.
Question: My double or single hung sash slipped out of the window before the balance shoes were locked in place. How do I place the sash back in the window? Instructional Video
Answer: Please view our instructional video for directions on how to correctly install an EcoShield double hung or single hung sash after either the sash was not lifted the required six inches before removal or the balance shoes slipped out of place when the sash was removed.
Question: What are new construction windows?
Answer: A new construction window is a window that is designed to be installed during the construction of a new building or addition. The new construction window has a nailing fin which allows the window to be nailed or screwed to the buildings wall before siding (or other exterior finish) is applied which allows for a tighter fit. Once the new construction window is installed the siding can be installed over the nail fin.
Question: What are replacement windows?
Answer: A replacement window is designed to fit easily and be secured in the opening that is left after removing an old window from a building. While a new construction window must be installed before finishing the exterior of the building a replacement window is designed to be installed so as not to damage the existing siding (or other exterior finish) while installing.
Question: What does the R-Value of an EcoShield vinyl window mean?
Answer: The R-Value refers to the rating system used in the building and construction industry to describe the thermal resistance of a window. The higher the R-Value the better as it will indicate a better thermal resistance. The R-Value refers to the thermal resistance of the window as a whole meaning the frame, the glass, and any other parts combined.
Question: What does the U-Factor of an EcoShield vinyl window mean?
Answer: The U-Factor measures the rate at which heat transfers and is an indicator of how well a window insulates. The lower the U-Factor the better the window insulates. According to Energy Star, U-Factor values generally range from 0.25 to 1.25.
Question: What is a bay window?
Answer: A bay window is similar to a bow window in that it projects outward from the building walls to allow for a better view than could be achieved by a flat window. The bay window typically consists of a large center picture window which is parallel with the wall of the building and two smaller windows on either side which angle out from the building walls to provide the projection. The two angled windows are often configured as a double hung or casement window to allow them to open for ventilation but they can also be fixed.
Question: What is a bow window?
Answer: A bow window is similar to a bay window in that it projects outward from the building walls to allow for a better view than could be achieved by a flat window. The typical bow window consists of three to five of the same sized windows which are angled to project outward from the wall of the building in more of a curve than the bay window which is more angular. The windows which make up a bow window can be configured as fixed windows or casement windows to allow them to be opened for ventilation.
Question: What is a casement window?
Answer: A casement window consists of a sash which opens outward on hinges along the side of the window frame similar to a door. A casement window usually uses a crank to open and close the window and keep it from closing or flying fully open from gusts of wind.
Question: What is a double hung window?
Answer: A double hung window consists of two separate sashes, a top sash and a bottom sash, which slide vertically in their own tracks to allow both sashes to be opened. The top sash can be opened fully while the bottom sash is closed fully, the bottom sash can be opened fully while the top sash is closed fully or both sashes can be opened half way at the same time. In any of these configurations the double hung window will provide a maximum face opening of half the total window area. The double hung window is equipped with either balances or springs which act as a counter balance to allow either of the sashes to remain stationary in any position when they are opened. Many double hung windows will operate in such a way as to permit the sashes to tilt inward to allow for cleaning on both the inside and outside of the glass from the inside of the building.
Question: What is a hopper window?
Answer: A hopper window consists of a sash which opens outward on hinges along thee bottom of the window frame similar to a hopper door. A hopper window usually uses a crank to open and close the window.
Question: What is a patio door?
Answer: A patio door is a sliding glass door made of at least 2-lites, one which is stationary while the other slides.
Question: What is a picture window?
Answer: A picture window is a large fixed window. The picture window is primarily to allow for an unobstructed view and does not open in any way to allow for ventilation.
Question: What is a rolling/sliding window?
Answer: A sliding, or rolling window consists of at least two sashes in a side by side (2-lite) configuration. Depending on the model of the window one sash may be stationary while the other sash opens by sliding horizontally or both sashes may open horizontally. In a 3-lite configuration there are three sashes, one stationary center sash with two outer sashes which operate horizontally to allow for ventilation.
Question: What is a sash?
Answer: Sash refers to the part of the window that secures the glass in the main window frame while still allowing the glass to be repositioned so that the window can be opened. For example, in a double hung window there is typically one main window frame which attaches to the wall to secure the window to the building and two smaller frames (the sashes) which hold the glass. One sash is positioned in the lower half of the window while the other sash is positioned in the top half. The bottom sash can then be slid upward or the top sash may be slid downward to open the window. Depending on the window style, a sash may be opened in other ways as well such as sliding horizontally, swinging outward like a door, or tilting upward like an awning.
Question: What is a single hung window?
Answer: A single hung window consists of two separate sashes, a stationary top sash and a moveable bottom sash. The bottom sash moves vertically to open or close the window and is equipped with either balances or springs which act as a counter balance to allow the sash to remain stationary in any position when it is opened. Many single hung windows will operate in such a way as to permit the sash to tilt inward to allow for cleaning on both the inside and outside of the glass from the inside of the building.
Question: What is an awning window?
Answer: An awning window consists of a sash which opens outward on hinges along the top of the window frame similar to an awning. An awning window usually uses a crank to open and close the window and keep it from closing.
Question: What is egress and how do I determine if it is necessary?
Answer: Egress or "means of egress" is defined as a continuous and unobstructed path of travel from any point in a building or structure to a public way. Building codes usually require at least one emergency escape exit and rescue entry way besides the doorway for any bedroom and also for inhabited basements. If a window is used as the "means of egress" then the building code has certain requirements that the window must meet such as the ability to be opened without tools by people on the inside and minimum opening area to allow people to escape out or rescuers to enter in through the window. EcoShield egress rated new construction windows and replacement windows meet "The National Building Code" or BOCA requirements for egress which are used in most building codes; however, the local building code should be consulted to determine what rooms require egress windows as well as required egress openings, window placement, hardware etc as building codes can vary from community to community.
Question: What is low-E glass?
Answer: Low-E stands for low emissivity which basically means that the glass is designed to reflect heat back to its source. This is accomplished by coating the glass with a very thin metallic layer allowing the short wave radiation which is the light from the sun to shine through while filtering out a percentage of the infrared light which is the heat. This process helps to keep your house cooler in the summer by reflecting some of the sun's heat energy back outside. It also helps keep your house warmer in the winter by reflecting heat from inside your house back inside. Low-E glass is available on all our new construction windows and replacement windows.
Question: What is the difference between vinyl and fiberglass windows?
Answer: The performance and energy efficiency of vinyl windows compares favorably to fiberglass; however, vinyl windows offer considerable cost savings when deciding between the two. To insure the longevity, performance, and energy efficiency of your vinyl windows, EcoShield replacement windows and new construction windows are backed with a lifetime warranty.

Question: Why do I get condensation on my windows?
Answer: Condensation is a common problem on windows, even highly energy efficient windows. This occurs more often in the winter but really any time the temperature of the glass reaches or goes below the temperature of the dew point of the air inside the house. The dew point is the temperature at which the air will no longer hold the moisture that is in it. Generally the more dry the air the lower the temperature of the dew point which is why condensation on windows actually tends to be more prevalent in newer houses or in houses with new highly energy efficient replacement windows. Older houses tend to be more drafty and as a result, the mixing of the dry air that seeps in from outside with the more humid inside air keeps the overall inside air dry enough to prevent condensation. Over the years houses have become better sealed to keep the warm air in and the cold air out in the winter. While this more efficient sealing of houses lowers the cost of heating it will also tend to keep the moisture in the house when the house is not ventilated properly or contains a lot of moisture producers. The condensation then occurs because even on a highly energy efficient window the temperature of the inside pane of glass will be somewhat cooler than the air inside the house being heated by the furnace. When the wet air inside the house creates a high dew point temperature and comes in contact with the cooler glass on the window the moisture in the air is drawn out and forms condensation on the glass. The solution to this problem is to reduce the moisture contained within the inside air so that the dew point is lower than the temperature of the inside pane of glass. The moisture in the house can be reduced by using exhaust fans in your bathrooms and kitchens and venting clothes dryers or gas burners to the outside which all expel a substantial amount of water vapor. It is also a good idea to make sure that the outside sensors on your furnace humidifier are set up properly so that the humidifier is not putting too much water in the air.
