Window Fitters Guide to Window Installation 115 ©2022 AWDI, LLC Do not reproduce without permission Installing Replacement Doors The key to replacing an old door with a new, energy efficient, weather-resistant door is to remove the old door and prepare the opening to be plumb, square, level and with a firm sur- rounding frame that you can properly mount the new to. Look through this book at both the window and the door installations to match your wall construction. Once you have determined what the wall construction is, remove the old door as carefully as possible to maintain the integrity of the structural surround and the weather barrier continuity. When the old door is removed, the proper integration of the 5 Barriers (see elsewhere in this book) has been destroyed and it will be tough to reconnect the comparable barriers in the new door system to the remnants of the same barriers in the wall. Lastly, old doors often are mounted in openings that have suffered water intrusion. Use impel rods in the frame where water has been and may still reside to prevent mold, mildew, rot and insect damage. Impel Rods are placed into holes drilled in wood at key locations. As the Rods dis- solve, the borate preservative migrates to areas of highest moisture and concen- trates where wood is most susceptible to decay. If the wood dries the Rods stop dif- fusing. The residual preservative remains in place. When the moisture content rises the Rods resume diffusion. Depending upon conditions of moisture, Impel Rods need not be replaced for years. A chart included in each package that shows rec- ommended rods sizes and spacing for each type of installation. There are three easy steps to installing Impel Rods: 1. Drill appropriate sized holes to accommodate the predetermined number and size of Impel Rods required. 2. Insert the suitable size and number of Impel Rods into the holes. 3. Seal the holes with treated wooden dowel, wood filler (like wood putty or caulk). Paint if desired.
