Top 5 Reasons to Choose Sandwich Roof Panels

In recent years, sandwich roof panels have become a game-changer in construction. These panels are self-supporting and serve two main purposes, they act as partitions for roofs or walls and provide thermal insulation. The sandwich panels differ by: 

• Thickness (40 to 230 mm)
• Length (2 to 18 m)
• Profile ( micro-profile, smooth, grooved, clearline, etc.)
• Core type (EPS, polyurethane, mineral wool) Cladding colors (both external and internal)
• Protective coatings (SP polyester Mat Pearl, polyester SP, aluzinc, Clear PUR 55)

Each panel has several layers, a core for thermal insulation, steel layers on the outside and inside, and coatings that protect against damage and rust. Read the article till the end to know more.

Reasons to Choose Sandwich Roof Panels

Reason 1 – Time is Money 

Let us compare as an example two common methods for building warehouses. The first method uses double brick walls for the outer partitions, while the second method uses sandwich panels.
With the brick wall method, we need to build the walls, add thermal insulation, and then install an external layer. This process is time-consuming and expensive.
With sandwich panels, the process is much simpler, faster, and cheaper. The sandwich roof panels are ready-made and easy to install, often on a steel structure.
In today's construction market, saving time is crucial for reducing costs. The faster a building is finished, the less we spend on construction services, which have become more expensive. A quick construction process also means the building can be used sooner by improving the return on investment for business projects.

Reason 2 – Three Specialized Cores or Solutions for Specific Needs

There are three main types of sandwich panels each with a different core material. The cores can be made of polyurethane, mineral wool, or EPS (expanded polystyrene). Each type is designed to meet specific needs.

Polyurethane-core sandwich panels

Polyurethane is the top choice for thermal insulation. It has replaced older materials like mineral wool and EPS in residential construction. These panels, made of hard polyurethane foam called Thermano, offer excellent thermal insulation with a lambda value of 0.022 W/mK which make them ideal for reducing heating costs.
Another advantage is that these panels save space inside buildings. Because they insulate so well, walls can be thinner than those made with other materials while still providing the same level of insulation.
Additionally, the core material has a low density (40 kg/m3), which makes installation easier. You do not need special tools or equipment to install these panels as it simplifies the construction process.

Sandwich panels with a mineral wool core 

The second type of panel offers two main benefits: fire resistance and soundproofing. Mineral wool panels are great in fires. Some panels have an EI 240 rating, meaning they can keep out fire and stay sealed for 240 minutes. This gives people enough time to leave the building safely and reduces fire damage.
These panels also prevent excessive noise. The best versions can soundproof up to 33 decibels by making them effective at blocking noise.

Panels with an EPS core 

The use of EPS (polystyrene) marked the beginning of sandwich panel history. Over time, EPS cores have been replaced by mineral wool and, especially polyurethane.
When comparing the three types, EPS panels offer moderate thermal insulation which falls between mineral wool and polyurethane. However, EPS is not as fire-resistant as mineral wool.
EPS-core sandwich panels are a cost-effective option. They work well when fire resistance or high thermal insulation is not a top priority.

Panel Joints 
You can also connect the panels together. This applies to panels with polyurethane or mineral wool cores. You can do this with panels that have visible fasteners (standard type) or hidden fasteners (plus type). 

Reason 3 – Connects Multiple Colors 

In addition to their main functions, industrial buildings are now also focusing on aesthetics. How our business looks? Whether it is a warehouse, factory, shop, or car showroom often influences how much trust people have in our brand. That is why adding a unique style to our project has become so important.
You will get many interesting options including different profiles, coatings (like matte finishes), and colors (over 30 to choose from). You can mix and match these designs to create a unique look that suits your business, whether it is classic or modern.
Sandwich roofing sheet is easy to clean because they have a smooth surface. You can use a standard pressure washer to clean them. The coating is resistant to water, so regular cleaning will keep your building looking new for many years.

Reason 4 – All Materials from One Manufacturer 

Panels come with a variety of accessories. These include flashings (available in any color, matching the panels) and different types of fasteners for fitting panels to different surfaces (like steel, concrete, or wood). You can also choose from a range of seals and gaskets to ensure the panels are tightly sealed.
When choosing sandwich panels, it is important to consider how much natural light you want. You can add small polyester windows, which come with matching flashings. This creates an attractive and well-protected structure that can withstand different weather conditions.

Reason 5 – Imagination is the Limit 

Sandwich panel structures are flexible in design. The material is easy to work with as it allows buildings to have windows and gates placed wherever needed. 

Conclusion 

Sandwich roofing panels are an excellent choice for any building project. They are durable, energy-efficient, water-resistant, and more. They are also easy to install and need little maintenance which makes them cost-effective. Whether you are building a new home or renovating a commercial building, you can consider using sandwich roofing sheet from Roofmate for your project.
