How to make a soundproofing curtain

Updated February 21, 2017

Making curtains of any kind requires only the most basic sewing skills and could, if necessary, be accomplished by hand -- though using a sewing machine will make the work faster and easier. A curtain is a flat panel of fabric, hemmed on the sides, the top and the bottom. In its most simple form, it hangs from a curtain rod or pole threaded through the top hem. A soundproof curtain is special because it must cover the door or window completely with about a 30 cm (12 inch) overlap on all sides. It must be hung high on the wall and reach the floor, and the curtain must be made of soundproof materials.

Decide on the placement of the curtain rod. Be sure to hang it as high as possible to eliminate noise leakage over the top. Plan to hang the curtain all the way to the floor. Measure the distance between curtain rod and floor. That will be the length of the finished curtain.

Add 20 cm (8 inches) to the length measurement. This will be turned under for hems on top and bottom.

Measure the width of the window or door to be covered. Add 60 cm (24 inches) to the measurement for the 30 cm (12 inch) overlap. Add 10 cm (4 inches) to the total width in order to turn under 5 cm (2 inches) for side hems.

Purchase the lengths of the thick soundproof MLV fabric in order to provide the width needed. For example, if the fabric is 150 cm (60 inches) wide and the curtain must be 250 cm (100 inches) wide, buy two lengths to sew together lengthwise. The result will be a panel 300 cm (120 inches) wide, which is just enough to create a little desirable fullness. Purchase additional lengths to create more fullness; it will improve the soundproofing quality of the curtain.

Turn under the 10 cm (4 inch) hems at top and bottom of the panel and sew. Turn under the 5 cm (2 inch) hems on the sides of the panel and sew. Thread the curtain rod or pole through one of the 10 cm (4 inch) hems, and hang the pole or rod. Arrange the fullness as desired. Secure the sides of the panel to the wall with hook-and-loop tape if desired.


Soundproofing can also be improved by hanging a double curtain by using a double rod intended for a valance or cafe panels. Simply hang one curtain over the other. Soundproof curtains may also be made from clear MLV yardage. This material admits light while the fabric MLV may restrict light almost completely. If curtain panels must meet in the centre, be sure to allow for a generous overlap of 30 cm (12 inches) or more. Secure closure of the overlap can be achieved with hook and loop tape.
