Frequently Asked Questions

Is sunlight reflecting off my window glass?

 Windows are reflective. When sunlight hits a surface, such as window glass, it sometimes reflects onto another object. The amount of sunlight reflected by window glass is increased when it has a low-emissivity (low-e) coating, which is purposely designed as an energy saving device to decrease the amount of sunlight entering a home. The reflection of sunlight off low-e window glass indicates the glass is “doing its job.”

For more information, see MIWD’s Information Statement on Solar Energy Reflection.

Is a WOCD (Window Operating Control Device) available on the MI EnergyCore windows?

Yes.  The WOCD is available as a factory installed option on the double hung window.  On the XO slider and single hung the WOCD is externally mounted and is installed in the field.

I have received my measuring form, what do I need to do now? How will I know if I measured correctly?

If you have questions or concerns on measuring, please go to our video library on the website.  You will find videos that will assist you with measuring.  If you have a form, please complete it in its entirety (i.e. color, grids, quantity, etc.) so that we can ensure correct ordering of the product.  The forms also include measuring instructions and all orders are checked for accuracy.

How much can I save by switching out my old windows with new energy efficient windows?

The answer will vary upon several factors, including the characteristics of your old and new windows, house size, geographic location, and personal use. ENERGY STAR® has calculated some estimates for replacing single-pane or double-pane clear glass windows with ENERGY STAR qualified windows. Ask your builder or distributor for information on MIWD windows bearing the ENERGY STAR label.”
