If you have a large sliding door with no window covering, the best option for window coverings is vertical blinds.
Vertical blinds, free hanging wide blinds that run floor to ceiling rather than horizontally, are a popular and usually economical solution to covering a hard-to-cover window. Experts also recommend vertical blinds, which are generally more durable than regular mini blinds, for high traffic areas with children and pets.
Vertical blinds block light efficiently and handle the job of insulating against heat and cold well.
PVC is the material of choice for the least expensive vertical blinds. You can also purchase vertical blinds with free-hanging fabric blinds or blinds where the fabric is inserts into PVC. These are the most expensive, but allow the homeowner a certain amount of customization to blend the blinds into the home decor.
Because purchasing the fabric vertical blinds are expensive, most homeowners who want the fabric look opt instead for fabric draperies or get the inexpensive neutral verticals, and then add fabrics around in a swag style for a more custom look.
As with any blinds, it is important to measure your window well. For vertical blinds, it is best to plan for an inside mount, which refers to blinds that are mounted inside the opening of the window or slider doorway.
This is the most popular mount of blinds today and provides for a clean, open look. If you choose to add fabric panels or another covering on top of the vertical blinds, using the inside mount for the blinds allows more room for the fabric hardware.
To measure, use only a steel measuring tape, since a fabric tape can stretch and give you inaccurate measurements. To measure the width, measure the width of the window opening in three places (bottom, middle and top). Round to the nearest 1/8 inch and take the smallest of the three measurements. This is the size you will order for the width.
For the height measurement, measure the window opening height in three places as well (right, middle and left) and round those measurements to the nearest 1/8 inch. Then take the largest measurement and use that for your height measurement. If you will be adding carpet or other flooring, be sure to factor in that before placing your order.
