Can energy savings pay for my new windows?

With Dayside Windows with Cardinal glass – we think it can!

Here is an example:
A savings of up to 30% can be realized when changing from single glazed wood windows to double glazed vinyl windows with “Cardinal” Low-E glass.

Say you spend $250 monthly on average on your energy bills, your annual spending would be about $3000. If 30% of energy is lost because of energy inefficient windows, the annual savings would be about $900. Over a ten year period that would amount to a $9000 savings!

That can pay for a lot of windows!

Enjoy greater savings with optional triple pane windows.

Maintenance Tips

Insulating Glass

Use a non-abrasive glass cleaner and a soft cloth

Low-E Glass

Since the Low-E coating is applied to the inner surface of the window pane, you can clean it the same way you clean insulating glass—non-abrasive glass cleaner and a soft cloth.


Use a non-abrasive, mild cleaner and a soft cloth.


Use a soft cloth or soft bristle brush for light cleaning
Use a household cleaner to remove difficult dirt and stains
If you use an abrasive cleaner, you could do damage to the frame
Do not use cleaners containing aggressive organic solvents (e.g., chlorine bleach)

Do I need new windows?

If there are no obvious signs that your windows need replacing—cracks in the frames, broken panes, water damage, mould, etc.—you can check to see how airtight your windows are easily. Simply hold a lit match to the edge of each window on a windy day. If it blows out and the smoke wisps away, you may want to invest in new windows with superior weather stripping.
