  • Why Buy Indow Windows?

    Q: Why use Indow Windows over purchasing new windows?

    Original windows match the home’s character and are difficult to replace without losing the aesthetic – at least not without considerable expense. Our product provides thermal insulation and increases your homes efficiency without construction.

    Q: I have old, drafty single pane windows, can Indow Windows help or do I have to buy new windows?

    Indow Windows window inserts can help! Adding Indow Windows will boost your current window performance to the equivalence of standard double pane window performance at about 15-20% of the cost.

  • Design and Function

    Q: How do Indow Windows stay in place?

    Indow Windows are held in place with our patented Compression Tube which expands into the space between the custom cut acrylic panel and the window frame.     

    Q: What colors do Indow Window’s come in?

    The Indow Window’s edging currently comes in white, brown and black. The brown is comparable to Benjamin Moore’s French Press.  For large commercial jobs, custom colors are available in any of the Pantone colors.  

    Q: Why do you use acrylic over film or glass?

    Acrylic is strong, light weight, and insulates very well. Acrylic has superior noise muting properties over film and is a better insulator than glass. Most films appear cloudy and are easily pierced by sharp objects. Glass is heavy and can shatter or chip easily. Indow Windows made from acrylic sheets are far easier to handle and store than glass.

    Q: Acrylic glazing? I’m concerned with how acrylic will look in my window frame.

    Acrylic is highly transparent and allows more light transmission than glass. When Indow Windows are installed, they are almost unnoticeable.

    Q: How noticeable are Indow Windows?

    Unlike cloudy film glazes and bulky framed interior storm windows, Indow Windows are frameless, composed of highly transparent acrylic glazing and practically disappear from sight when installed into a window frame.

    Q: What are safety straps used for?

    Safety straps are used in the event of high wind pressure from the outside of leaky exterior windows. Indow Windows create such a tight fit that air pressure can build up and work to push the Indow Window out. During high wind events, some of your Indow Windows might vent air pressure in the corner or along a side. This is normal and you can simply push the corner or side back into place. The straps are designed to prevent the Indow from falling completely out of the window frame, which is unlikely to happen.

    Q:  What if I want to open any of my windows while Indow Windows are installed?

    Indow Windows remove easily and reinstall just as easily. 

    Q: How do I remove and reinstall Indow Windows? Is this difficult?

    Indow Windows remove and install very easily. Remove by simply pulling the small tab and unhooking the safety strap (if present). Reinstall by lining each corner up with the window frame and pressing it into place. Tip: We generally try to put the bottom corners in first to align the Indow, and then the top corners followed by the top and sides.

    Q: Will the inserts trap condensation?

    Thermal window inserts should greatly reduce or entirely eliminate condensation on existing single or double pane windows. The Compression Tube effectively stops warm moist air from reaching the glass. Most clients find that they can see outside their kitchens for the first time during dinner in the wintertime. There will be times when the acrylic will start to fog up but not nearly as severe as the glass would. If condensation is repeatedly appearing inside the glass or fogging up the acrylic, then there is most likely an existing condition in the wall that should be addressed and remedied.

    Q: How do I tell which Indow Window goes into which frame?

    We use a laser engraver to mark the backside of the bottom left corner of each Indow Window to denote what window frame the Indow goes into. Our numbering system starts on the left immediately entering the house at #1, proceeding from left to right. Each room is also individually denoted.

    Q: Can you mount them on the outside?

    Indow Windows are made for the interior of your home.

    Q:  Do you make Indow Windows for screen doors?

    Indow Windows does not currently manufacture Indow Windows for screen doors.

    • Features a low profile design that almost disappears when installed, allowing your home’s own beauty to shine through

    • Enhances your home’s resale value, preserving the initial investment
    Q: I live in a noisy urban area; will Indow Windows help reduce any of the noise?

    Standard Indow Windows will reduce noise coming through single pane windows by up to 50%, Acoustic Grade Indow Windows dampen sound by up to 70%.  This is one of the most important benefits for some of our customers! Demonstration

    Q: Will Indow Windows add any benefits to double pane windows?

    Indow Windows added to your double pane windows will boost efficiency, increasing thermal performance and noise reduction. 

    Q: Where would you recommend Museum Grade (UV filtering) & Commercial Grade (scratch resistant)?

    Many clients order Museum Grade for areas where direct sunlight is a concern to protect furniture, art, carpets or kids from the damaging effects of the sun’s UV rays. Commercial Grade is generally ordered for areas near the kitchen sink where it will be washed or wiped off more often or removed frequently. A pet or child with a sharp object will still be able to damage Commercial Grade Indow Windows.

    Q: Will Indow Windows add to my mold problems?

    Window mold is generally caused by window condensation. Condensation happens when moist air comes into contact with a colder surface, such as a window. Indow Windows help prevent window condensation through insulating the warm home air from the cold outer windowpane.

    Q: Will the inserts trap condensation?

    Thermal window inserts should greatly reduce or entirely eliminate condensation on existing single or double pane windows. The Compression Tube effectively stops warm moist air from reaching the glass. Most clients find that they can see outside their kitchens for the first time during dinner in the wintertime. There will be times when the acrylic will start to fog up but not nearly as severe as the glass would. If condensation is repeatedly appearing inside the glass or fogging up the acrylic, then there is most likely an existing condition in the wall that should be addressed and remedied.

    Q: I’ve had exterior storm windows in the past and wasn’t satisfied with their performance.  Will Indow Windows be able to outperform storm windows?

    Exterior storm windows are designed to protect against rain and, sometimes, against strong winds. Indow Windows are designed to insulate windows from cold and heat, reduce sound transmission and provide better thermal and acoustical insulation than traditional storm windows. If you’ve used exterior storm windows in the past, you’ll easily be able to feel/see the difference with Indow Windows.

    Q: What is “R Value”?

    R-value measures the thermal resistance of walls, windows, and other parts of a building. An Indow Window combined with a single pane window provides 94% of the thermal insulation of a standard double pane window. Look closer

  • Durability

    Q: How long do Indow Windows last?

    Indow Windows should last over ten years. Check out our warranty statement for more detailed information.

    Q: Doesn’t acrylic turn yellow over time?

    The acrylic we use to make Indow Windows does not yellow, crack or discolor from exposure to UV radiation or simple aging.

    Q: Doesn’t acrylic scratch very easily?

    If not cared for properly, especially with storage and cleaning, acrylic will scratch. Many scratches can be buffed out with an acrylic repair kit. If scratching is a concern, we offer a Commercial Grade Indow that has a durable, scratch resistant coating.

    Q: How durable is the edging and will it fade?

    The edging is similar to the material used to make silicone oven mitts and cooking spatulas. It was chosen for it’s durability and it will not fade from exposure to UV or be affected by heat or cold.

    Q: Will the acrylic crack?

    The acrylic glazing has a high strength to weight ratio and will not crack if handled properly.

  • Where They Work

    Q: Which types of windows/frames will Indow Windows work with?

    Indow Windows can be fitted to square, rectangular and other polygonal windows. Each window frame is precisely measured which allows us to create the precise shape of your window even if the window is not perfectly square. Custom shapes such as arched windows are available in select markets. For a proper fit, there must be an unobstructed flat edge within your window frame with a depth of at least 5/8” that runs the entire perimeter of the window.  

    Q: Will Indow Windows work with curved windows?

    Yes, Indow Windows can be made to fit curved windows.

    Q: My windows are not standard size; can I still use Indow Windows?

    Yes, each Indow Window is custom made to fit each window.

    Q: My windows are out of square.  Will Indow Windows still work?

    Indow Windows work very well with out of square windows without any modification to the windows themselves.

    Q: What’s the largest window size Indow Window will work in?

    Size restrictions have many variables according to width, height, window function and air leakage. If you have windows larger than the sizes we currently offer, please call to inquire. We may be able to meet your needs.

    Q: Will Indow Windows work with my blinds and curtains?

    Indow Windows will work with various window treatments if the curtains or blinds are mounted to the face of the window frame rather than to the inside. 

    Q: Is there any construction required for installing Indow Windows?

    Aside from the safety straps, which install with one screw, there are no additional nails, adhesives, or screws involved in the installation and no construction required to the window frame itself.

  • Upkeep & Care

    Q: I see fog or moisture collecting on the inside of Indow Windows, what do I do?

    Indow Windows almost always dramatically reduce condensation on the original single (or double) pane windows.   If condensation does occur, it often indicates a problem with moisture build up in the walls.

    Q: How do I clean my Indow Windows?

    Indow Windows can be easily cleaned with a microfiber cloth with or without a mild soap mixture. See our Care Guide

    Q: Can I repair scratches?

    In some cases, it may be possible to lessen the appearance of scratches by using a plastic polish such as Novus 2 or 3 which can be found at most major hardware stores. Be careful to follow the manufacturer’s directions as the incorrect use may damage your Indow Window.

    Q: How do I store my Indow Windows?

    Many Indow Windows can be left in place year round. If an Indow Window is removed for an extended period proper storage is essential. We make high quality custom-fitted, clear storage sleeves made from a 5mm nylon-poly blend. If you choose to make your own sleeves be sure to consider the abrasiveness of the material to avoid scratching. The best option is to store them flat on the floor with the largest on the bottom, no more than 3 high to prevent bowing or warping.
