Composite cladding panels or systems have been present since the 1930s when American architects Frank Lloyd Wright and Alden B.Dow used these panels in their construction projects. In modern, modular construction, prefabricated sandwich panels are being utilised in various sizes, configurations, thickness, finish, profiles, and edge details to meet the requirements. They are particularly useful in high-performance construction and offer unique advantages such as thermal insulation, fire resistance, structural strength, low weight, and much more.
If you are looking for prefabricated roofing panels and want to choose the right one, then you will find all your answers here. So, let’s get started!
A sandwich panel is a three-layer construction material that consists of a thermo-insulating core with metal sheets on both sides. Primarily used for external cladding, sandwich panels can be used for walls as well, ceilings, as well as roofs.
Usually, the outer sheet of the panel should be resistant to fluctuating temperatures caused by weather, wind, sun (UV rays), and other physical or chemical effects. The inner sheet on the other hand is not affected by similar factors as the outer sheet but has to be resistant to internal conditions such as chemical gases or condensation.
When selecting wall sandwich panels, customers usually consider factors such as strength and fire resistance whereas, for roofing panels, load-bearing capacity and long life are more relevant. Moreover, since roofing panels need to have air-tight capability, panels with a special profile of external facing in the form of ridges are usually recommended.

Sandwich panels can be of the following types depending on the core material:
These core materials vary based on their thermal insulation, fire resistance, sound insulation, etc. and you can make a choice depending on your construction need. Additionally, the outer surfaces are made of metals including pre-painted galvanized steel, stainless steel, aluminium, or zinc.
PUF-insulated panels have become an attractive choice in modern, modular construction, especially in prefabricated buildings, warehouses, cold rooms, and others.
Here are some of the reasons why PUF panels are the future of construction!
The energy efficiency of a sandwich panel depends on its core and the air-tightness of the locks. PUF panels offer high thermal insulation which means they can help maintain ambient or the required temperature inside the construction. This translates to energy savings!
The sandwich structure of PUF panels ensures effective acoustic shielding. Since they don’t let the sound pass through, PUF panels are particularly useful in the construction of theatres, auditoriums and construction near or on highways or busy roads.
PUF panels are anti-corrosive and can withstand extreme weather conditions including winds, rainfall, or snowfall to keep the structure protected. These panels are also low-maintenance and thus can be built in different geographical locations.
PUF insulated sheets are light in weight and are easier to transport and install. Especially, on the construction site, the handling is easy and requires comparatively less manpower for installation. This means savings on labour and resources! Plus, with PUF panels, it is much easier to dismantle, move, or expand the construction. Its reusability thus makes it a sustainable option.
Since PUF sandwich panels are low-maintenance and weather-resistant, they ensure sturdy and durable structures with a long life.
Some other features that make PUF insulated panels a great choice for construction projects include:
PUF sandwich panels find applications in the following:
Below are the general steps but can vary depending on the manufacturer and the project requirements.
1. Prefabricated sandwich panels are transported to the site of construction with the required components.
2. The materials are then unloaded with appropriate construction handling equipment.
3. The subframes and secured using beams, purlins and posts.
4. Protective films are removed from the PUF panels.
5. Sandwich panels and subframes are fastened using appropriate fasteners.
6. The joints between the PUF panels are sealed for air and water tightness.
Unlike conventional modular construction that requires costly transportation, Rinac’s clean modular construction (CMC) is truly modular and is completely prefabricated and knocked down.
Our PUF sandwich panels are cost-effective, lightweight yet sturdy, easy to maintain and construct, as well as have high-temperature and sound insulation properties and come with the following features:
