Specification Brand : ZSTARR BulletPoint1 : 【Material】:ZSTARR Cordless Roller Blinds are made of 100% polyester fabric with a reinforced insulating coating that is soft and smooth to the touch. Easy to clean, our blackout blinds effectively block sunlight and UV rays, and their insulated backing reduces indoor heat loss and protects against the cold that passes through your windows in winter and summer, helping to lower your energy bills. BulletPoint2 : 【NEW DESIGN】: These are bottom-up lampshades, not top-down lampshades. Can be stretched at will to stop at any position, very light, children can also operate, and the traditional drawstring curtain contrast, this is safe because we upgraded to cordless BulletPoint3 : For in-frame installation:Please fill in the custom form with the exact measurement of the opening to 1/8 inch, or if your window opening is a full inch, select 0/0 so the shade will fit perfectly in the opening. The shade must be slightly smaller than the opening to fit inside. We do not make any deductions, so give us exactly 1/8 inch for the opening. For interior installations, you need a minimum depth of 2.95 inches at the top of the window. BulletPoint4 : For exterior sash installations: we do not make any deductions - provide us with the exact size you want the sash to be when you fill out the custom form. Traditionally, exterior mounts are installed above the window opening and are slightly wider than the window opening by at least 2.5 inches or more when choosing a width dimension so that the sash will block the light perfectly. BulletPoint5 : 【Important】The width of roller shades for windows includes side brackets or valance edge (which takes up to 0.5'' on each side), so the actual fabric width is 1.1'' narrower, which sometimes will let the light come in if the shade is inside mounted to the window frame. To solve the light leakage, we also offer the light blockers at ZSTARR store.
