Aluminum roofing and siding sheets are roll formed from hardened, tempered metal for maximum strength. Aluminum siding is very versatile, and features designs that mimic other materials, such as wood. This type of siding also comes pre-painted in your desired color, which saves on paint costs. Aluminum siding is very hardy and weather-resistant, and has an estimated lifespan of 20 years.
If a sheet must be bent, a gentle 90-degree bend is the maximum recommended. Metal should not be re-bent once it has been formed, nor should it be folded back on itself. When a metal roofing sheet must be installed on a curved roof, screws should be installed at every overlapping rib at the sheet ends to resist the natural tendency of the metal to spring back.
To make a cut parallel to the ribs, score the panel deeply with a sharp utility knife and bend back-and-forth along the score, breaking the metal off cleanly. For cuts across the ribs, use straight -cut tin snips, electric or pneumatic shears, a portable profile shear, or an electric nibbler. Some people prefer using a circular saw with a metal cutting blade. Light oil or soap on the blade will make cutting easier.
To get an impressive finish, you have to prepare the wall properly. Clean the walls to remove the dirt and debris like old paint, putty or caulking. If you find any nails on the walls, they should be hammered inside. Any small or big depression should be filled up with wedges.
The aluminum trim, metal base line and fixture boxes should be installed before the siding courses are fastened. This allows you to nail the fasteners without obstructions and to plum lines to follow for spacing purposes.
After placing the sheets of the siding on the wall, you have to fix them. The correct way to fasten steel panels with nails is to drive the nail through the top of the rib so the washer is compressed securely against the metal. Nail placement must be in the ribs for roofing applications to minimize the potential for roof leaks.
Over-driving the nail can split the washer and dimple the metal, causing leaks. Wood screws with combination metal and neoprene washers should be installed in the flat area of the panel adjacent to the ribs, and tightened such that the washer is compressed. This will ensure a lasting, leak-proof seal.
Be careful not to fix up the aluminum siding very tightly, as the siding may get bent due to temperature expansion and contraction. On every wall, a gap of three-fourth inches needs to be kept to fix up the corner caps.
When the installation of aluminum work is finished, you have to fit the corner caps on each corner of the wall. Slide the rims of the corner caps under the edges of the panels of aluminum siding and then fix them up with nails so that the sheets are joined together.
Once you have installed the aluminum siding, you are free from any kind of maintenance of the external wall of your house. All you need to do is to clean up the siding once every year and paint it once in maybe 5 or 6 years.
Benefits of Aluminum Siding
Aluminum siding is fireproof as well as waterproof. Aluminum siding can last for several decades and does not require much maintenance. It does not get rusted like steel siding. The cost of aluminum siding is much less as compared to other house siding like brick stone and wood siding. It provides more effective insulation to your house as compared to vinyl siding. As it is a good insulator of heat, it will assist your furnace or air conditioner to work at its maximum efficiency throughout the year.
As with any material, aluminum does have a few downsides as a siding product. First and foremost, it isn’t as tough as some of the other materials on the market. It can dent and scratch easily in the hands of careless homeowners. The other criticism of aluminum siding is that it has a tendency to corrode at times.
