Sheers on doors are popular, but many people think they're too frilly, old-fashioned, do not want to always block their view, or are afraid they'll get the fabric soiled from dirty hands.
The key is to think of the door as a window, which happens to be in a door. It is usually best to use the same products as those already on windows in that room, for consistency. A blind or shade will work just fine, and can be easily fastened at the bottom of the door. It is common to use hold down brackets at the bottom so your product won't flop around as the door opens and closes. The product can be easily removed from the bracket whenever you want to raise it.
When you have a window with the view of a golf course, pool, mountains, etc., you should consider a product such as a shade, that pulls up as tightly as possible. Honeycomb shades are perfect. The Top-Down/Bottom-Up option is common.
Wood blinds have the bulkiest stack, with 1" having the worst because they have twice as much wood.
The most popular type of window treatment are honeycomb shades which fans into a semi-circle. While horizontal blinds can be made to fit arches, they are generally cost prohibitive.
Any product will work in a bay, but if there's no sheetrock between the windows be aware of possible gaps where the products "meet".
Consider using a highly efficient insulating honeycomb shade, which lets light in, but blocks heat and cold. The shades can move, with the help of an optional collapsible wand. Special shades can be ordered with side rails for support. Be sure to specify that your shade is for a skylight, since there's a surcharge.
If you want a shade, consider the Top-Down/Bottom-Up feature, which allows you to cover the bottom half of your window and not block your view. For instance, if your child is studying, he or she might not want to close off the outside view, but may feel more comfortable blocking people from seeing into the room.
Verticals are very popular for sliding doors, despite their diminishing popularity in general. They can be installed within the frame or over the glass, but don't necessarily choose a vertical if the other room products are something other than verticals. Consistency is important, too. Another possibility is a honeycomb shade that is essentially sideways and runs along a track by hand. You can also use horizontal blinds, but should consider putting two-on-one headrail, to make it easier to get out (you can raise one side and leave the other down).
Room darkening honeycomb shades provide superior insulation. The more honeycomb cells (the most is 3) and the larger the cell size (the largest is 1 1/2"), the better the insulation. When closing blinds, you'll maximize their insulation if you close the blinds with the leading edge up.
Whenever a window covering is extremely large, its weight makes it difficult to raise and puts unnecessary tension on the strings (which may cause the strings to break). You may need to consider a special control option. If the shade is very large, everyone will benefit from this option. The manufacturers have size guidelines that tell you whether the controls are suggested. One type is called EasyRise; another EasyUp. Small children and elderly people sometimes need this option even on smaller shades.
For blinds, consider dividing them up into multiple blinds on a single headrail, or order multiple blinds and install them side-by-side. Usually there are multiple windows within a single opening, so you should usually divide up the blinds to line up with the windows. When you do this, order ONE valance to span all the headrails to make it appear to be one single product.
Consider specifying extra long cords so you can open or close a product. Some honeycomb shades and blinds can be made with a remote control.
It is common to want the front of your home to be as uniform as possible-just how uniform is up to you. Most people just make sure that the front products are generally white. Most honeycomb shades have white backings despite their colored inside-facing fabric. Some aluminum mini blinds can be made as "duo-tones" which are white on the back.
If a stained room faces front and you're using wood shutters or wood blinds then you'll have to decide if it's acceptable visually. Most homeowners think this is fine.
The more symmetrical your home the more likely the products should be similar. People often use one product across the front; however, many also use one for the first floor and another for the second. It's your house, so whatever you feel is appropriate should be fine.
All quality products are water resistant. Even good wood blinds are varnished and perform well under humid conditions. If your window gets direct water pressure (it's located in a shower) only a 100% vinyl product will perform well.
To eliminate glare on a TV or computer monitor, or to prevent a bright security light from beaming in to your bedroom, use blinds with no route holes. One vendor calls this the De-Light feature and is excellent. The De-Light feature is optional on wood blinds, and comes standard on some aluminum blinds. Blackout shades are excellent, too.
If you have rambunctious kids in your home, you should get the highest quality, sturdiest products. Aluminum mini blinds come mainly in two gauges (8 and 6) - get the 6 gauge. We highly suggest blinds with spring-tempered aluminum that resist kinking better than all others. Some mini blinds have clutch systems on their tilting mechanisms preventing over-tightening. There are some blinds which have DustShield, to repel dust from collecting on your blinds.
Fauxwood blinds are an excellent choice because they are durable, resist abuse, and are easy to clean.
