Begin installing insulation beneath vinyl siding by choosing an appropriate insulation. Follow the instructions of the siding manufacturer to know the type and thickness of insulation required.

Then, ensure that the siding does not show any signs of damage due to water. Also, take out nails that are loose, and hammer them flat in place.

To mark the baseline, first identify the lowest spot of the home using a level and a measuring tape. Then, consult the instructions of the siding manufacturer, and determine the distance upwards from this point to know where the siding installation must start. Mark this spot using a pencil, and with a chalk and a level, mark the baseline around the home.

When cutting the insulation panels, make a half-cut into the panel's thickness, and snap the panel. Then, gently move the knife along the bend to cut the panel into two pieces.

To install the cut panels, use ring-shank nails that are resistant to corrosion and come with a plastic cap. Position nails at a distance of 16 inches from one another along the panel's width and length. After installing the insulation in all the required areas, install the vinyl siding.
