There is nothing greater than opening a screened door or window to allow fresh air to filter into the house. Putting in a screen door used to be a huge process in that the entire frame would need to be replaced. However, today you can simply remove the old door and add another one on. If you do not already have a screen door, you will find that they are a wonderful way to cut down on cooling bills while letting fresh air in.
The first thing you need to do is measure the length of each piece of 2x4-foot framing and then adding those measurements together. The total of that measurement would be the amount of lineal footage of 1 1/2-inch base and cap that you will need. You also need to measure the length of each piece of 4x4 framing, again totaling that number. This total will then be the amount of lineal footage of 3 1/2- base and cap material to buy.
Next, measure the length of the framing members that need only one spline of the side and base, adding the measurements. Then, measure the length of the framing members that need the spline on both sides of the base. Again, total these measurements. Now you want to multiply the first set of measurements to the second set. The number you get is the amount of lineal footage of spline that you will need for your screen door.
Keep in mind that if you choose aluminum screen, you will need .160-inch spine but for fiberglass screen, you need .175-inch. The next step involves measuring the opening from the outside of the frame. You want to take the height and multiply it by the width to come up with the total square footage of screen you will need.
To install the screen in your new door, you will cut the base strips so they fit the door�s vertical framing members. Next, the base will be attached with one-inch screws to the framing members. Make sure the screws are not too tight or the base can be damaged. Now cut your base strips so they fit the horizontal framing members. Then attach them so they fit up snugly to the vertical base.
The screen will then need to be stretched very tight over the door opening. However, be careful with this process so the screen is not pulled so tight that it is damaged or deformed. With a concave wheel, you want to install the spline into the channel located at the base. When about six to eight inches of screen has been started, you can use a convex wheel to help push the spline into the channel securely.
Then with scissors made for screening, cut off the excess piece of screen, discarding. Keep working with the screen in six to eight inch pieces and when done, you want to cut the cap pieces so they fit into the vertical base pieces. Finally, use a rubber mallet to snap the cap into place and then cut and install the cap pieces for the horizontal base.
