5 Common Materials Used for Capsule House Exteriors
A capsule may look simple from the outside, but its exterior is made from different materials. Note that the same exterior shape may have different types of materials and panel structure underneath. Actually, the exterior of a capsule house is decided based on several factors like design, durability, weather, and overall cost.
The exterior of a capsule house affects how your house looks and performs. Some materials are strong, others are lightweight yet strong. In this blog, we will discuss the most common material used for capsule house exteriors so that you can make a wise decision. Keep reading!
1) Solid Aluminium Panels
Solid aluminium is one of the most common and widely used materials for the exterior of capsule houses.
Why Aluminium Is Commonly Used
Aluminium is commonly used because it is lightweight and strong. Curved structures can be easily made with aluminium. Well, when the structure has curved and round walls, aluminium performs best. It offers a smooth and premium exterior shape. The house looks clean and modern from outside.
In addition, aluminium offers good resistance against corrosion. Therefore, it is suitable for outdoor environments. The level of protection depends on the surface treatment used for aluminium. Also, aluminium is lightweight. It reduces the overall weight of the outer part of the house.
Well, aluminium panels are available in different finishes and colours. You can choose the one that suits your project.
Coatings and Surface Finishes
The outer coating on the material plays an important role in the overall performance of the capsule house. Generally speaking, Fluorocarbon-coated aluminium is one of the best options available. Well, the coating improves the resistance of the aluminium against corrosion and weather. The surface can keep its look and shape for longer.
Aluminium comes in different gloss levels. Some offer a bright metallic appearance, others may offer a softer and understated look. So, when you compare different aluminium panels, consider the metal and its coating, as well. A good surface treatment can make more difference than you think.
2) Aluminium Composite Panels
How Aluminium Composite Panels Are Built
Aluminium composite panels are different from solid aluminium sheets. Actually, the aluminium is present around the core material. It offers a layered design. Also, it is lightweight and offers a smooth and premium exterior surface.
Here, keep in mind that the core material can vary from panel to panel. So, you can’t judge the panel by looking at its super aluminium surface. The construction has a direct effect on the stiffness, weight, and overall performance of the exterior.
For modern architectural designs, these panels are best. They offer a clean and flat surface, which is usually required for good finishing.
Main Considerations
One of the most important factors that you must consider before selecting aluminium composite panel is the material of the core. Different cores offer different levels of performance. Apart from this, you also have to consider the thickness of the panel. A thicker panel may offer different levels of strength and other characteristics.
Also focus on the surface finish of the panel. Some finishes are specially designed for the exterior. In addition, pay attention to the durability. If the panel is too inexpensive, it may not provide the level of durability you are expecting.
3) Coated or Galvanised Steel Panels
Main Characteristics
Steel is another great option for capsule house exterior. It is strong and long-lasting. But the thing is that it is heavier than aluminium. The additional weight of the steel can affect the requirements for transportation. Also, it can affect the structure of the house. Therefore, it is better to consider the full panel structure before selecting the steel.
Steel panels often offer a durable and solid exterior surface. These are available in different coated and painted finishes. Galvanised steel also uses a protective zinc layer to reduce corrosion. Other steel panels use other specialised coatings to protect the steel surface. Well, the right treatment is the one that suits the installation environment.
Surface Protection
When you use steel for outdoor purposes, it needs protection. Yes, moisture and other external factors can destroy the surface of steel if it is not protected. So, you can use galvanised steel. Additionally, painted and coated surfaces can also be useful.
Well, edges, joints, and connection points are also worth considering. If the protective layer becomes damaged, these areas become vulnerable.
Proper installation of the panel is equally important. Install well so that water may not get trapped around joints or exposed connections.
4) Insulated Decorative Metal Panels
Panel Structure
Insulated decorative metal panels provide an exterior surface and an insulation core. So, now the panel is serving two functions. The outer layer is building the exterior surface of the house, while the insulation core is helping improve the thermal performance.
The exact performance of the panel depends on its thickness and type. Also, the quality of insulation affects the final results. Well, when you want both insulation and appearance, these panels are best. They are also available in different styles.
Common Finish Options
Wood-look finishes are popular for capsule houses used in natural surroundings. They can create a warmer and more residential appearance.
Stone-look finishes can provide a different visual style. They may work well for resorts, gardens, and outdoor accommodation projects. Smooth metal finishes offer a cleaner and more modern appearance. Patterned surfaces can also add visual interest to the exterior.
These options allow you to match the capsule house with its surroundings. You can create a modern, natural, or decorative appearance.
What to Consider
You should check the insulation core before selecting an insulated panel. Different core materials have different thermal and fire-related properties.
Panel thickness is also important. Thicker panels may provide different insulation performance and structural characteristics.
Joint treatment deserves attention as well. Poorly sealed joints can allow water and air to enter the panel system. You should also inspect the quality of the exterior finish. A good finish should be suitable for long-term outdoor exposure.
5) FRP and Molded Composite Panels
Why Molded Composite Materials Are Used
Alright! FRP and molded composite panels are also used for this purpose. FRP stand for Fiber-reinforced plastic. It is a combination of reinforcing fibres and plastic resins. FRP and other composites can be molded into different shapes, simple or complex. So, this material helps you make unusual and extraordinary exterior designs.
They are relatively lower in weight. So, it offers a smooth and consistent outer surface.
Okay, so these materials are considered best for creating different shapes, curves, surface patterns, and textures on the surface of the exterior of a capsule house.
Main Considerations
When you choose FRP for your capsule house exterior, UV resistance becomes an important factor. As time passes, continuous sunlight can affect the material. Moreover, you should consider colour retention. Use a suitable grade of the material that can maintain its appearance during demanding outdoor conditions.
Surface ageing is another point to check. Different products can age differently depending on their formulation and coating. Repair methods also vary between composite panels. Minor surface damage may be repairable, while serious damage may require panel replacement.
Before buying, ask about repair procedures and replacement availability. This can make future maintenance of the exterior of a capsule house easier.
6) How to Choose the Right Exterior Material
The right choice of material depends on the location, design, budget, and maintenance plans. All these factors matter!
Climate and Weather
First, consider the environment where you have to install the capsule house. You know, coastal areas are usually exposed to salt and humidity. These conditions can increase the chances of corrosion. So, there’s a need for good moisture protection. Pay close attention to joints, drainage, connections, and surface coatings.
High-UV locations create another challenge. Strong sunlight can affect coatings, colours, and composite surfaces over time. Cold climates require materials that can handle repeated temperature changes. Expansion and contraction can affect panels and joints.
You should therefore choose materials based on your local weather conditions.
Appearance and Project Style
The appearance and style of the capsule house also depend on the material used. If you use metallic finishes, they create a futuristic and modern appearance. For contemporary capsule houses, they are best.
Wood-look finishes create a warmer look. If the location is somewhat like a forest, garden, or natural landscape, they may fit well.
Stone-look finishes can provide a more traditional or resort-style appearance.
You should consider the surrounding landscape before selecting a finish. The exterior should complement the location rather than compete with it.
Maintenance and Repair
Every exterior material requires some level of maintenance. However, the type and frequency can vary.
Regular cleaning helps remove dirt, dust, and other surface buildup. You should follow the manufacturer's recommended cleaning method.
Scratches and coating damage should also be addressed when necessary. Damaged surfaces can become more vulnerable to outdoor conditions.
You should also ask about replacement panels before buying. Matching an older finish can sometimes be difficult.
A material with simple repair options can save you time later. Easy access to replacement parts can also reduce maintenance problems.
Budget and Long-Term Use
The cheapest exterior material is not always the most economical choice. You should consider its complete cost over the capsule house's lifespan. Initial material cost is only one part of the calculation. Installation, maintenance, repairs, and replacement can also affect your total cost.
A more durable material may have a higher initial price. However, it could require fewer repairs over time. You should also consider how long you plan to use the capsule house. A temporary project may have different priorities than a permanent accommodation site.
Compare the initial cost with expected maintenance and replacement needs. This gives you a more realistic view of the investment.
