PerfectFIT DuoShade Chocolate Thermal Blind

Measure the visible glass area of your window. Measure from the inside edges of the frame where the glass meets the rubber bead. Our conservatory blinds fit neatly inside the frame of your window or door to effectively cover the visible glass.

For accurate measurements, make sure you use a metal tape; cloth and plastic ones can stretch, leaving you with inaccurate readings.

The frame depth of your window is the 'thickness' of your PVC frame, from the glass out to the front of the frame.

The brackets we send with your blind will need to protrude far enough from the glass to clear the frame, so we offer a range of bracket sizes to cover a variety of frame depths. Simply choose the option from the drop-down that matches your window's frame depth.

An easy way to check your frame depth is to place a credit card or store card over the corner of the frame, then measure out from the glass to the edge of the card.
