You might think that the steps on how to install interior metal wall panels at your home, office, or other space are hard. When, in fact, it is easy, and you only need to follow a few methods to have metal wall coverings for the interior.

If you do not know how to install interior metal wall panels, check out these easy steps and tips for panelized metal wall systems in your home.

6 Steps on How to Install Interior Metal Wall Panels

Here are six easy steps on how to install interior metal wall panels:

Step 1: Initial inspection

The first thing you should do is conduct an initial inspection before you install the metal sheet on the wall. Check if there are cracks on board and rotten areas. You cannot establish a metal wall paneling on a soft surface since it cannot carry its weight.

Aside from that, you should also check protruding objects such as electrical wirings, outlets, and pipes. This way, you can ensure they will not get damaged as you install the metal paneling for walls.

Step 2: Material preparation

Prepare the necessary metal wall covering materials as you finish the initial inspection. The primary materials and tools you will need are metal sheets, an impact driver or drill, metal screws, small metal drill bits, and a jigsaw.

Step 3: Removal of old deck, side, and underlayment

Remove the damaged parts you have seen during the inspection to prepare the surface where you will install the metal wall panels. You can get a crowbar to remove the rotten parts easily.

Step 4: Measure and cut door and window trim pieces

As soon as you clear out the area where you will install the metal wall panels, start measuring the door and window trim and cut them. Do this to ensure a correct fit before you secure the trimmings with the screws.

Step 5: Install the base trim

Install the base trim


To install the base trim, measure it first and ensure it is on your metal wall panel level before you secure it.

As you secure the pieces to the structure, you will see metal shards. Sweep off these particles on the metal surface to prevent rust formation.

Since the base trim will serve as the foundation, always check if it is on the right level as you secure it. It will make the structure sturdier and permanently in place.

Step 6: Steel wall panels installation

Down to the last procedure on how to install interior metal wall panels is the actual installation itself.

Ensure that the wall panels are leveled, plumbed, and squared before you attach them since they will be the cornerstone of all the other connected panels. Once the first panel is securely fastened on both edges, you can begin to install the other panels.

Using a spacer, check if there is equal spacing on each wall panel on the opposite of every screw. You should install the support flashing around the doors and windows to hold the steel wall panels.

Measure and cut the door and window openings from the steel panels. Again, tiny metal shards will appear as you cut them, so remove them immediately.

Lastly, fit the custom-cut panels around the doors and windows. You can test the fit to ensure the stability of the metal wall panel.

By following all these steps on installing interior metal wall panels, you can do it properly and finish it as you please.

Different Types of Metal Wall Panels

For additional information as you plan on how to install interior metal wall panels, here are the different types you can use:

Single skin metal

It is a cheap metal wall panel and the most commonly used. There are two types of single-skin metal, namely the concealed fastener and the exposed fastener.

The concealed single-skin metal has a higher quality and is often used by architects and designers because of its modern and clean look.

The exposed fastener is less expensive and offers fast and easy installation.

Insulated metal panels

As its name suggests, insulated metal panels or IPMs feature insulation properties that you can install easily and quickly.

The insulated sheet metal wall panels have interior and exterior finished surfaces to help you reduce the time, money, and effort of installing them.

You can often see IMPs on warehouses, cold storage, and architectural structures such as airports, hospitals, schools, and stadiums.

Metal-faced composites

This type of metal wall panel is from a thermoplastic core and is almost similar to IMPs. The only difference is that metal-faced composites do not have thermal value.

Most architectural structures use this type for more cost-effective designs.

Perforated metal

If you prioritize design in your interior metal wall panels, you should opt for the perforated metal. It uses perforated facades for decorative purposes. It combines aesthetics and technology to provide endless variations in patterns, styles, and sizes.

Plate panels

The plate panels are suitable if you prefer more freedom when working on your interior metal wall panels. Most designers use it because of its functionality. You can use it on different curves, depths, perforations, substrates, and tapers.

Benefits of Using Metal Wall Panels

The metal itself serves a lot of functionalities for construction purposes. Installing metal wall panels on your interior space also offers several benefits.

Easy installation

In building construction, time plays an integral part. If there is a slight delay, it can impact the project’s cost. Thus, builders and designers choose metal panels for faster installation than other materials such as bricks and Exterior Insulated Finishing systems (EIFs).

Low maintenance

Metal wall panels can last for an average of 20 to 30 years. During the period, you will also notice the lesser need for maintenance.

However, metal panels are still not susceptible to extreme weather conditions. In that case, you must apply preventive maintenance to prolong its quality.

Conduct regular inspections, wash the walls, and replace any damaged panels as soon as possible to prevent them from wearing down quickly.


Nowadays, sustainability should be of great importance and priority. Metal wall panels offer an eco-friendly building material since it is lost-lasting and recyclable as long it is still in good condition, resulting in lesser waste, especially in the construction and building industry.


Metal panels are also versatile. You can use and place it anywhere you please. It also provides endless design ideas ideal for those who love aesthetics.


1. Why should I use metal wall panels?

Metal wall panels are strong, durable, and offer insulated protection for different building purposes. Proper care and maintenance can increase its quality and life span from damaging factors such as air, corrosion, heat, vapor, water, and extreme weather conditions.

Because of these quality features, it is a good value for money, and you can also recycle it for your other building projects.

2. What is the difference between single skin and IMP panels?

Skin single metal panels are excellent for exterior walls, while IMPs are ideal for interior walls. Still, you can use either depending on the overall design and build you want for your wall panels.

3. What is the difference between exposed and concealed fastener panels?

Concealed fastener systems are more adaptable and flexible compared to exposed fasteners. However, exposed fasteners are more economical and easier to use.

4. What are my options for concealed fastener wall panels?

There are several options for concealed fastener wall panels you can choose from, such as MSR panel, FW panel, and Wave panel.

The MSR panel balances out aesthetics and strengths.

The FW panel is ideal for horizontal and vertical applications.

The Wave panel is more attractive and provides flexibility to adapt to any design. Similar to the FW panel, you can install it horizontally or vertically.

5. What types of coatings are available on metal panels?

There are three types of coatings you can use for metal panels. These are the anticorrosive coatings, paint coatings, and coatings for maintenance.

Anticorrosive coatings are ideal for aluminum, zinc, or a combination of these two metals. You should apply it directly on an uncoat metal surface to eliminate galvanization.

Paint coatings are for aesthetic purposes, but it also does add protection. You should use siliconized polyester when choosing a paint coating for metal panels.

Maintenance coatings, as its name implies, protect the metal panel from several damaging factors over time.
