Sandwich panels are modular building materials designed to cover buildings and structures. These panels consist of two specific layers that form the outer structure and ensure form, weather resistance and rigidity. They contain a core that provides thermal and acoustic insulation properties. From durability and energy efficiency to versatility, ease of installation and lower cost, you’ll see why these panels are becoming a go-to choice for architects, builders, and property owners alike. So, whether you’re planning to construct a new building or extend an existing one, read on to discover why sandwich roofing panels should be at the top of your list. 

How Big Is a Sandwich Panel? 

The width of the insulation board is usually 1,000 mm, and, in some models, it is about 1,150 mm wide. The length of the sandwich panel can also be adjusted according to the needs of each project, the most common dimensions being between 3 and 6 metres, but, in some cases, a maximum length of nearly 16 metres can be reached. The thicknesses of these panels can vary enormously depending on the final application, the most common values being between 40 and 150-200 mm thick depending on the application. 

The Several Reasons to Use Sandwich Panels:

Effective insulation makes a building completely comfortable for the users of the interior spaces and helps to increase its property value. Furthermore, it minimizes the environmental impact of the construction activity. 

Besides good insulation, sandwich panels also have other diverse features that make them a useful solution: 

1. mechanical resistance to the stresses 

2. fire reaction and its resistance 

3. lightness and the ease of installation 

4. resistance to wear and tear in the weather 

5. possibility of being mounted on top of the existing roofs 

6. versatility of solutions: the panels for curved, inclined, and flat roofing 

7. variety of finishes to suit different architectural styles 

 

The Thermal Insulation of Sandwich Panels:

Sandwich panels make for a consistent insulating surface, minimising the risk of thermal bridges. Thanks to their high insulating performance, they are extensively used in sustainable construction and buildings designed specifically for energy savings. 

Depending on their thickness and the material used in the core, the panels’ thermal conductivity and insulation values can change significantly. This allows the size to be correct based on the specific requirements. 

 

Benefits of Sandwich Roofing Panels:

 

• Durability & Long Life:

One of the most significant advantages of sandwich sheet roofing panels is their durability. These panels are made from high-quality materials that withstand harsh weather conditions like stroms, heavy rains, strong winds, and extreme temperatures. They are also corrosion-resistant so that they won’t rust or deteriorate over time. This makes them an excellent choice for buildings in harsh weather conditions. With newer technology like edge protection and weather-shield from Pronto, the life and durability of these panels increase multifold. 

Sandwich sheet roofing panels are also known for their long life. Since they are made from durable materials, they can last for decades with minimal maintenance. This means that you will be okay with replacing your roof sometime soon, which can save you much money in the long run. 

 

• Energy Efficiency:

Another benefit of sandwich sheet roofing panels is their energy efficiency. These panels are designed to provide highly excellent insulation, which means that they can help keep your building warm during winter and cool in summer seasons. This can help you save money on your energy bills, as you won’t have to rely as heavily on heating and cooling systems. 

Sandwich sheet roofing panels are also great at reducing heat loss, which can help you create a comfortable environment for your building’s occupants. This is particularly important for commercial buildings, such as offices and retail spaces, where the comfort of customers and employees is crucial to the business’s success. 

 

• Heat Resistance Insulation:

Another great benefit of sandwich sheet roofing panels is their ability to resist heat. It’s 1 lac times more insulating compared to ordinary metal roofing sheets. The insulation layer between the metal sheets helps to prevent heat from penetrating the roof, which can helpto keep your building cool in the summer. This is particularly important for buildings in warm climates, where excessive heat can make the indoor environment uncomfortable. 

Sandwich sheets can also help reduce the heat absorbed by your roof, which can help extend its life. Excessive heat can cause roofing materials to deteriorate over time, leading to leaks and other problems. 

 

• Water Resistance: 

Sandwich panels are also highly water-resistant, making them an excellent choice for buildings in areas with heavy rainfall. These panels come with a watertight, interlocking mechanism that helps to prevent water from seeping through the roof, which can help prevent leaks and other water damage. 

The insulation layer between the metal sheets also helps to prevent the water from seeping through the roof. This is because the insulation layer creates a thick lock that allows water to penetrate these panels, preventing it from entering the building. 

 

• Sound Insulation:

In addition to providing excellent thermal insulation, sandwich sheet roofing panels also reduce sound transmission. This is because the insulation layer helps to absorb the sound waves, preventing them from passing through the roof and into the building. 

This makes sandwich sheet roofing panels an excellent choice for buildings located in noisy areas, such as near busy roads or airports. They can also be a good choice for buildings where noise reduction is essential, such as music studios or conference rooms.
