What is External Cladding?

What is External Cladding

External cladding is one of the most important elements in architectural design.
It defines the look and feel of exterior spaces and significantly affects a building’s performance.
Modinex is a specialty manufacturer and supplier of architectural cladding products.
If you’ve been wondering what external cladding is, Modinex has compiled this guide to assist.

Understanding Cladding

Cladding also forms an air cavity between the cladding material and the building’s structure.

This air cavity is crucial for thermal insulation and allows air flow within the walls, which prevents mould and rot.

While exterior cladding comes in many formats, most products serve the same purpose. Here are the functional purposes of exterior cladding:

The outside of a building experiences sun, storms, pests, dust and more. Cladding protects structural materials from damage due to moisture and weather.

Cladding is part of a building’s insulation schedule. The cladding layer creates an air gap and protects insulation materials from moisture and UV damage.

Building facades can reflect, absorb and transmit sound. If you live in a noisy area, exterior cladding can control sound and make your home comfortable.

Exterior cladding is the appearance layer, so it’s used to enhance the aesthetic of buildings. Cladding is often a key feature in architectural projects.

Common Types of Exterior Cladding

There are dozens of materials commonly used for cladding in modern buildings.
This is not an exhaustive list, but it includes some of the most popular options for residential and commercial projects.

Timber cladding is one of the world’s oldest and most popular materials.

These products use natural timber to protect your building against moisture, UV and pests.

While timber cladding comes at a premium, it’s a stunning material that can elevate an exterior design.

Modern products come in hundreds of formats, allowing you to achieve almost any architectural vision.

In addition to its beauty, hardwood timber cladding is incredibly durable, long-lived and suitable for harsh environments.

It needs slightly more maintenance than some alternatives, but it can set your project apart.

Fibre cement is a composite cladding material made of cement that has been reinforced with cellulose fibres.

 

While it was once a low-cost material for industrial buildings, it has become popular as an architectural finish.

Fibre cement cladding offers excellent mechanical performance.

It’s highly resistant to moisture, sun, pests, and bushfires and can last for decades in the Australian climate.

The major benefit of fibre cement panels is that they can be dyed and formed into a range of attractive products.

This makes it easy to add details such as shadow lines or coving to the outside of a building.

Aluminium cladding is a popular choice for residential and commercial projects.

It offers excellent thermal performance and can be manufactured to look like natural timber.

While exterior aluminium cladding often comes at a premium, it’s one of the most durable and long-lived solutions on the market.

It’s also available in timber-look, powder coated and anodised finishes, so it’s versatile enough to fit with most design aesthetics.

Brick is one of the most common cladding materials in Australia.

Traditional clay bricks can last almost indefinitely, and they provide excellent protection against Australia’s sun and storms.

The same can be said for natural stone cladding. Installing natural stone is particularly laborious, but it creates a striking appearance that pairs well with timber cladding.

Composite cladding (also called engineered cladding) is a product that’s a blend of wood fibre and plastic. Composite cladding is durable and low maintenance.

Because it’s a combination of materials, composite cladding may last longer than traditional timber cladding.

High quality composite cladding can be more expensive than the alternatives, but it looks fantastic and it offers some of the best mechanical performance on the market.
