Helpful Information About Alustra Architectural

Before measuring, consider whether you want an inside or outside mounted window treatment. If inside, you’ll need to make sure your window is square by measuring horizontally at the top, center and bottom, vertically along both sides and center, and diagonally. Also measure the frame depth and take into account any window hardware that might obstruct the window treatment.

A helpful hint: Ask your local expert to measure all your windows, so the measurements are on hand for future projects.
