The best way to Flash a Vinyl Window

Vinyl windows that are flashing function toward the best and should begin in the base of the window opening. Doing this produces the overlaps required rather than allowing it to seep inside, to divert water. A typical mistake is setting the window in the opening too soon in the procedure. This compromises the usefulness of the sill flashing in the underside. Flashing another one goes much faster as soon as you properly flash a vinyl window. Obtain a sheet-metal flashing that is sill centered on the thickness of the wall framing, including flashing or 4 inches. Obtain materials listed under to flash a vinyl window and the flashing.

Sill Flashing

Measure the width of the window opening that is rough on the other side of the bottom, and include 4″. Mark and measure the sheet-metal sill flashing this size. Cut the flashing with sheet-metal cutters to size.

Make a 2 inch-long cut in the changeover bend — from broad to narrow. Bend the extensive parts at every end upward — reverse of the part that is slim — 90-degrees with pliers or sheet-metal benders.

Place the flashing on the underside of the window opening using the portion over the outside the opening. Extend both shortcut, or bend the ends of the part that is broad, as required, to get a uniform, comfortable fit.

Cut 1/4 inch off the tip of the plastic nozzle on a tube of flashing sealant using a utility knife. Insert the rod on a gun to the opening, and puncture the seal on top of the tube. Load the tube to the gun.

Install the flashing firmly.

Window Installation and Flashing

Close and latch the panels that are sliding . This guarantees while you set the window, the body stays square. Place the window in the opening in the outside the building. Push it in to place so the fins on leading and the sides of the frame are against-the-wall framing or moisture-management substance.

Ask an assistant to steady the window in the opening as you le Vel the bottom fringe of of the window — horizontal — with A24-inch-lengthy le Vel. Ask the assistant to support the the window le Vel.

Drive A6- penny nail a T every side through one of the upper-most holes in the fin, and partly to the wall framing. Recheck the base of the window with all the level. In the the lower facet of the window, pull the nail if required before the window is le Vel, and elevate that facet. Drive a nail completely to the upper most hole in the fin only at that side. Drive the nail in the side that is contrary.

Drive nails that are extra in the holes on the sides and leading of the body, and snugly in to the wood framing. Don’t nail the part of the flashing.

Measure the peak a-T one aspect of the windowframe and a DD 8″. Cut two-pieces of selfadhesive window flashing tape for this length with all the utility knife.

Fit one-length of the flashing in spot a-T one facet of the window. The conclusion extends completely within the slim part of the flashing, and one lengthy edge is butted from the aspect of the window body. The conclusion proceeds onto the facial skin of the header over the window.

Remove the protecting backing and press the size of flashing in to spot. Repeat the process and flash the reverse facet of the window of flashing using the remaining size.

Measure and minimize still another size of selfadhesive flashing that completely overlaps the edges of the flashing a T every side, and spans the very top of the window. Remove the protecting backing and press the flashing in to location. The exterior wall is prepared for siding and trim only at that window.
