Horizontal Window Blinds
Horizontal blinds are the most common window treatment around because they're just so practical. They're the one treatment that can absolutley go into every single room in the house and cover all various needs. They can make a room very dark and you can control just how much light you want in the room. They are also the most economical window treatment available in most cases.
Horizontal blinds come in 2 and 2.5 inch louvers and we've taken to the faux wood louvers because they'll never warp. We also have real bass wood horizontals but with the amount of heat and humidity here in Florida they will start to warp after several years.
Horizontal blinds are not really designed to be raised and lowered often however, they are very heavy treatments and lifting them puts a lot of stress on the strings. The one time I will reccomend the bass wood blind is if a customer really wants to raise and lower it often though, the wood is lighter than the faux wood.
When you have a whole house of windows to cover the cost can get up there pretty quick. One the best ways to stay in line with the budget is to put horizontals in guest bedrooms. Those tend to be rooms that don't get used as much and often with several different purposes. The blind is ideal here, it can make the room dark enough for when company visits but gives you plenty of light if you use it as an office or exercise room. Garages are another perfect place for a faux wood blind. The excessive heat and humidity can be tough on any treatment which really limits us to faux blinds, vinyl shutters, or a sunscreen roller shade. The price point of the blind trumps the other options while giving you all the privacy and light control needed.
