Wrap Window Treatments
Most window openings that will be exposed to dust should be entirely covered with plastic. But for windows you need to open, cover the window treatments in plastic instead of removing them. Removing window treatments is risky business: Parts disappear; metal slats bend; fabric rips or gets dirty. And replacing damaged treatments can get expensive?if you can even find one that matches, that is. Tape plastic to the top of the casing, then tuck the plastic up underneath and behind it. Open the window to tape the plastic on the back of the treatment to the top jamb.
Don't forget to remove the screens. Screens and construction don't mix. One of the very first tasks of any remodeling job is to remove all the screens from any window or door that could be in harm's way. Label each one so they all find their way back to the right place. Wrap them in plastic and put them in some safe out-of-the-way location.
Friction-Fit Dust Barrier
Every remodeler knows that building a temporary wall covered in plastic is a great way to keep dust from migrating to other parts of the house. But here's how to do it in a finished room without damaging the surfaces. Wedge strips of R-11 insulation (3-1/2 in. thick) between the framing and the ceiling and the walls. The insulation creates a friction fit and holds everything in place without fasteners. The insulation also allows a little air to flow but acts as a filter.
Start by setting the bottom plate on the floor where you want it. Hold up the top plate with insulation on top of it. Have a helper wedge a couple studs between the top and the bottom plates every 4 ft. or so. Cut the studs 3-3/8 in. shorter than the wall. That allows for the thickness of the plates and leaves a 3/8-in. gap to squish the insulation. Install the plastic with a staple gun rather than a hammer tacker so you don't knock the wall over. Double up the plastic at the top for a more secure hold. Write 'Don't Lean on Wall' with a marker to prevent unfortunate accidents.
