SCREENS: REPLACEMENT AND RESCREENING

 

PLEASE SELECT YOUR SCREEN ATTACHMENT TYPE:

 

WINDOWS WITH PERMANENT SPLINED IN SCREEN:

SCREEN REMOVAL: Remove all the clamp ring screws and take the window out of the wall.  Working with the window on a flat surface, loosen the screen spline at a corner using long nose pliers.  The spline will come out in pieces. You will need new spline of a like diameter, available from home centers or glass shops.  The damaged screen mesh will then pull out easily.

NEW SCREEN INSTALLATION: Cut a piece of screen mesh about two inches larger than the maximum screened area. Center it over the area to be screened.  Using the new spline and a narrow wheel screen roller, spline the screen into the screen mullion. Keep adequate tension on the screen mesh as you go, but make sure not to cut the mesh with the roller.  After the straight section is in, start working around the remainder of the frame.  Do not stretch the spline. If the screen begins to bunch or distort, you can pull the spline out and start over, as long as you have not damaged the mesh. If possible, keep the screen mesh square in the frame. That is, do not let the weave of the mesh angle up on a side. After you are finished, check that the tension on the screen mesh is satisfactory. After insuring that you have not damaged the window flange seal, reinstall the window in the hole.  If the flange seal must be replaced, there are several good window sealants on the market.  If using a liquid sealant, choose one that will not harden or become brittle.  If using a foam tape, choose the closed cell type, and be sure it will compress adequately to allow proper clamp ring installation.  Follow package directions if new sealant is needed.

 

 WINDOWS WITH “HANGING TRACK” SCREENS:

SCREEN REMOVAL: Open the window and screen fully. With a lifting motion, raise the screen frame until it clears the bottom screen support clips. On shorter height windows, it may be necessary to bow the screen sides slightly.  Be careful. Do not bend the screen frame so much that it takes a permanent “set.” Working with the screen frame on a flat surface, loosen the screen spline at a corner using long nose pliers.  When the spline has been loosened, it can be pulled out intact. Be careful not to damage or sever it. The damaged screen mesh will then pull out easily. 

NEW SCREEN INSTALLATION: [NOTE: There is a tendency to spline screen in too tight, causing the sides to bow inward.  Two ways to avoid this are: (1) Order a complete new screen assembly, or (2) block the inside edges of the frame with flat wood or metal strips nailed to the worktable surface, so that the screen frame sides remain parallel. Cut a piece of screen mesh about two inches larger than the maximum screened area. Center it over the area to be screened.  Using the old spline and a narrow wheel screen roller, spline the screen into the screen frame. Keep adequate tension on the screen mesh as you go, but make sure not to cut the mesh with the roller.  After the straight section is in, start working around the remainder of the frame.  Do not stretch the spline. If the screen begins to bunch or distort, you can pull the spline out and start over, as long as you have not damaged the mesh. If possible, keep the screen mesh square in the frame. That is, do not let the weave of the mesh angle up on a side. After you are finished, check that the tension on the screen mesh is satisfactory. Replace the screen frame onto the window by reversing the procedure above.

 

 

 WINDOWS WITH METAL WIRE SPRING CLIPS:

SCREEN REMOVAL: Using a suitable Phillips head screwdriver remove the operator knob or crank and screw. Pry the screen frame from the backframe carefully using a thin, stiff putty knife.  Be careful not to mar the window frame. [NOTE:  For windows with a center operator, the operator shaft protrudes through the screen mesh in a formed grommet.  You may elect to replace the screen mesh without the grommet by making a small cut in the screen.  Overall, for a better look and longer screen life, we recommend that you order a new screen assembly, rather than trying to reuse the old screen frame. ] Working with the screen frame on a flat surface, loosen the screen spline at a corner using long nose pliers.  When the spline has been loosened, it can be pulled out intact. Be careful not to damage or sever it. The damaged screen mesh will then pull out easily.  

NEW SCREEN INSTALLATION: [NOTE: If necessary for working space, carefully remove the spring clips, and set them aside.] There is a tendency to spline screen it too tight, causing the sides to bow inward.  Two ways to avoid this are: (1) Order a complete new screen assembly, or (2) block the inside edges of the frame with flat wood or metal strips nailed to the worktable surface, so that the screen frame sides remain parallel. Cut a piece of screen mesh about two inches larger than the maximum screened area. Center it over the area to be screened.  Using the used spline and a narrow wheel screen roller, spline the screen into the screen frame. Keep adequate tension on the screen mesh as you go, but make sure not to cut the mesh with the roller.  After the straight section is in, start working around the remainder of the frame.  Do not stretch the spline. If the screen begins to bunch or distort, you can pull the spline out and start over, as long as you have not damaged the mesh. If possible, keep the screen mesh square in the frame. That is, do not let the weave of the mesh angle up on a side. After you are finished, check that the tension on the screen mesh is satisfactory. If otherwise OK, install the metal spring clips into the screen frame, snap the screen frame back onto the window frame, and reinstall the operator knob and screw.

 

 

 WINDOW WITH SCREEN SLIDING IN WINDOW FRAME:

SCREEN REMOVAL: Open the window and screen.  Press upward on the screen frame top, pushing the frame deeper into its pocket.  This will compress the springs and allow the screen frame bottom to rotate out of the bottom track. Be careful with the plastic screen springs, so that they can be re-used. .  Working with the screen frame on a flat surface, loosen the screen spline at a corner using long nose pliers.  When the spline has been loosened, it can be pulled out intact. Be careful not to damage or sever it. The damaged screen mesh will then pull out easily.

If otherwise OK, replace the screen into its channel.  Check for proper installation by sliding the screen back and forth.

 

 SQUARE SCREENS WHICH SLIP INTO THE WINDOW FRAME:

SCREEN REMOVAL: The screen frame sides are exposed on the interior, while the top and bottom are held behind the window frame. Supporting the frame sides with the thumbs, lift the screen frame straight upward until the bottom clears the bottom of the window frame. Rotate the screen frame out of its opening. Working with the screen frame on a flat surface, loosen the screen spline at an end using long nose pliers.  When the spline has been loosened, it can be pulled out intact. Be careful not to damage or sever it. The damaged screen mesh will then pull out easily.
