How to Install Quality Insulation
- 1). Select the appropriate insulation batts from your local hardware or construction store. Insulation comes in a variety of lengths and is measured in R-values. The batt widths are sized to fit the majority of wall framing applications. Use R-30 or R-38 if filling ceiling or attic spaces, whereas R-13 to R-21 is used for wall insulation. As most walls are spaced at 12, 16 or 24 inches and either 8 or 9 feet high, you can easily pick out what you need. Measure the space between your wall framing and the height and select what you need based on this measurement.
- 2). Remove the insulation from the package by cutting it lengthwise through the side panel. Avoid cutting into the insulation panel.
- 3). Remove the panel and gently push it into the cavity in the wall so that it is firmly in place. The edge of the insulation should be snugly touching the corner and edges. Pull the panel forward so that it fills the entire depth of the cavity. Make sure the vapor retarder or backing is facing the interior space. This is the space that you are trying to insulate.
- 4). Line each panel on top of the other one until they reach to the top of the ceiling. Staple the flanges of the panels together to keep them in place. Perform the same steps for the insulation panels in the other wall dividers. Don't stretch the flanges too tight when stapling as it could compress the insulation panel or create a gap.
- 5). Cut the insulation so that it is about an inch wider for floor installations. Use a utility knife for this task.
- 6). Secure the floor insulation with wire fasteners. This will connect the floor insulation pieces so that they bow up against the floor and don't compress. Compression can reduce the R-value of the insulation. The fasteners should fixed about 6 inches from the end of the panel and about 12 to 24 inches apart.
