You'll find that using quality, cheap film treatments and coverings are excellent strategies to save money and provide a shield of protection from the elements.
- Blinds
When it comes to saving money, cellular blinds will definitely provide you with an insulation barrier. In fact, they're very effective at keeping heat in or out of your home.
In the summer, you'll find these blinds do a great job of keeping the sun from beaming through your windows; keeping your home cooler and keeping your AC bills low.
In the winter, they'll help keep heat in your house; putting less strain on your furnace or
geothermal unit.
The best blinds will be light colored and face the outside of your home to better reflect away the suns heat.

- Shades
We use vertical roller shades and love them. Cost wise, they're cheap window shades which do a fantastic job of keeping our home insulated. They're a great heat reflector and they're close to the glass.
These shades can also be reversed. One side is dark with the other side light.

- Awnings
When it comes to energy efficient window coverings, awnings deserve an honorable mention. They're a great way to shade your home from direct sunlight to prevent it from heating up in the summer.
You'll find the two main types of awnings to be either hood or venation. Venation awnings are retractable which block perpendicular sunlight. If you go with the hood awnings, they have folded sides which block the sun from entering your windows from the sides.
You'll benefit more from the venation awnings because they're retractable. You can have these awnings overhang to block the sun in the summer and retract them to allow more sunlight into your home in the winter.
- Energy Saving Window Film
You can further insulate your home using plastic film, also called window kits. These will come in handy for a drafty window or one that isn't double pained. You'll find this to be an extremely budget friendly window insulation technique.
You can purchase these window kits at your local hardware store.
