When choosing shutters for your home, there are many things to consider including:
-Louver sizes which range from 1 7/8" and go all the way up to 5 1/2" -Frame types from simple bull nose to detailed molding -Hinge types from surface mounted hinges to a higher end hinge which is a mortised hinge -Hinge colors ranging from silver, powder coated, painted, antique brass, bronze oil rubbed or even brass to name a few -Tilt options from a standard tilt rod to a hidden tilt rod otherwise know as "Clearview" -Header options from a simple "mouse hole" - no pun intended :) to a liberty arch cutout -Colors and stains - if you think it we can color it, we match any color and any stain out there -Panel configurations - there are many ways to configure your panels from cafe style to double hung, to bypass to bifold there are a large number of configurations that best suit your needs.
The bottom line is buy your shutters from a reputable company, the lowest price is low for a reason. Does the company have good ratings on the web, are they licensed contractors if that is required in your area, how long have they been in business, what is their BBB rating? These are all things to consider before making your purchase.
