What is the exterior wall cover method?
This page will explain the recommended points, precautions, and costs related to the exterior wall cover method!
The exterior wall cover method is a construction process that overlays a new exterior wall on top of the existing one.
It can be applied to various types of exterior walls, including ALC walls, ceramic siding, and mortar walls.
The materials used for the exterior wall cover method are generally lightweight and durable metal sidings.
While the costs are higher compared to exterior wall painting, this method of exterior wall renovation has various advantages and is gaining attention year by year.
Why is the exterior wall cover method so popular?
Here are the “five points” that explain why Kakeru Koumuten’s exterior wall cover method is well-received!
Point 1 Super high durability!!
Metal siding offers an overwhelmingly high expected lifespan compared to exterior wall painting.
There are different types of metal siding, including galvalume steel, SGL steel, and aluminum, and with aluminum, you can expect a lifespan of over 40 years!
Additionally, unlike ceramic siding or mortar walls, it does not crack or break, making durability one of its advantages!
If high-durability sealing materials are used, maintenance may not be needed for nearly 30 years!
Point 2 Improved insulation!!
The metal siding used in the exterior wall cover method comes with integrated insulation.
Moreover, by installing battens before the metal siding, a ventilation layer is created, significantly enhancing insulation performance!
This improvement in insulation is arguably the greatest benefit of the exterior wall cover method!
Point 3 Comprehensive warranty for peace of mind!!
While many construction companies offer their own warranties for exterior painting, manufacturer warranties are generally not included.
Metal siding comes with solid manufacturer warranties such as coating and perforation guarantees, making it a reassuring choice for long-term exterior renovations!
Point 4 Improved waterproofing!!
The double layer of exterior materials significantly enhances waterproofing by preventing rainwater intrusion.
Applying waterproof paper before construction further increases waterproofing effectiveness!
Point 5 Enhanced design!!
Various designs of metal siding, including wood grain and tile patterns
Metal siding allows for a finish that resembles a new construction, which is impossible to achieve with exterior painting.
There are various designs available, from simple styles to tile and wood grain patterns.
You can choose from a variety of designs to match the atmosphere of your building and your personal preferences!
What should you be aware of when it comes to exterior wall cover work with metal siding?
Next, we will explain the “three points to be cautious about” when using the exterior wall cover method with metal siding!
Caution 1 Few contractors can perform the work
There are significantly fewer contractors capable of performing the metal siding cover method compared to exterior painting contractors.
Many inexperienced contractors exist, leading to potential issues and price variations.
If you are considering the metal siding exterior wall cover method, be sure to obtain estimates from at least three companies and carefully review the details!
Caution 2 Prone to dents and scratches
Metal siding can develop dents from impacts when objects hit it.
Additionally, susceptibility to scratches is one of its drawbacks.
If noticeable scratches occur and are a concern, you can request repairs from a specialized repair contractor!
Caution 3 Long construction period
The exterior wall cover work is arguably the most extensive renovation among exterior renovations.
While exterior painting typically takes about 2 to 3 weeks, the exterior wall cover work can often take nearly a month.
The lengthy construction period can be a source of stress for residents, making it one of the drawbacks.
