Thing's You Will Need

Step 1: Inspect Interior Walls
First of all, you need to inspect the interior walls when it comes to installing the rigid foam insulation. Look over for any moisture problem on the interior walls before applying a waterproof paint on the affected area. If the problem that you have come across while inspecting the interior wall is major, then it is important to take the help of a professional.
Step 2: Attach The Strips
After inspecting the interior wall and successfully dealing with the moisture problem, if any, you now need to attach the furring strips. The furring strips may be composed of wood or metal particularly designed to support surfaces once installed. With the help of adhesive or a ramset, attach or secure the furring strips against the walls 16-inches separated from each other. This kind of strip will give you a level surface in order to attach the insulation and any covering drywall or paneling you are looking to use.
Step 3: Level The Surface
It is certain to happen that walls have irregularities, therefore, it is important to use a shim material in order to level and correct the irregular walls. Shims are generally thin wood wedges that are sold cheaply or recycled scraps of wood, however, they can be metal as well. Shim the furring strips in order to level them into place.
Step 4: Install The Panels
Now, with the help of a measuring tape, take the measurement of the rigid foam insulation panels before marking the size needed. Trim the foam with the help of a knife or saw & use the mark as guide. Look over whether the panels conveniently fit with the installed furring strips. After that, press the panel in betwixt the strips. Make sure that there is no space or any gap left in betwixt the insulation boards as a protection for your boards. Apply an adhesive tape or caulks on wall areas having spaces or gaps.
Step 5: Secure The Foam Insulation Boards
The plastic insulation perform duties or services as added protection to your rigid foam insulation panels. This will help prevent the water vapor from penetrating the panels in order to avoid further damage. In stapling the plastic insulation do this with utmost care and prevent tacking it on the furring strips thereby pierce and making a hole in it unnecessarily. You can now protect the insulation with drywall or paneling by securing them to the furring strips.
