About this item 100% Vinyl ATTENTION PLEASE READ. We can customize these 5% solar shades up to an 1/8th inch. Once you click your size and color you will see a "Customize Now" button on the top right. You then type inside the window frame mount or outside the window frame mount and you exact measurements to the 1/8th of an inch. You will also see 3 lift options. Order slightly larger sizes in the drop down. For example, if you need 24 1/2w x 48 1/2 order the 25w x 49h size and then customize if from there. For an inside mount, give us the exact measurement of the opening to the 1/8th inch and WE will take a 1/4 inch deduction off the exact measurement given so the shade will fit perfectly in that opening. The shade has to be slightly smaller then the opening to fit inside. Again we take the deduction so give us the exact opening. You need at least 2 inches of depth at the top of the window for an inside mount. For an inside mount you will have a slight gap on each side because the brackets take up a little over 1/2 inch on each side then you have the material. All widths include the brackets. So material width will be at least 1 1/4 inches smaller. Keep this in mine for an outside mount because you can go wider unlike an inside mount where you give us the exact opening to the 1/8th inch. All solar shades have 3 lift options. A continuous cord loop or cordless lift options are available. Any Width over 84 wide or 84 high will have to have a cord on the right or left side. These are 5% solar shades that block sun but still give you a view. These custom sunscreen solar shades come in every size from 15 to 96 inches wide. 5% solar shades have a lifetime warranty.
