What Are Sandwich Panels and How Do They Work?

INTRODUCTION
Sandwich panels are a type of modular building
material used to cover structures and buildings.
These panels are made up of two layers that serve
as the outer structure, ensuring form, weather
resistance, and rigidity. They have a core that
provides thermal and acoustic insulation.

POLYURETHANE SANDWICH PANEL PROPERTIES
The excellent insulation provided by polyurethane
sandwich panels is one of their most important
characteristics. The plates core provides low
thermal conductivity, resulting in better
insulation. As a result, it is frequently used in
building renovations, both on roofs and facades,
as well as in the construction of industrial
buildings. Sandwich panels are quickly
manufactured and installed. They are screwed to
the structure for assembly, and depending on the
finish, they can be visible or concealed screws.
As a result, the construction time is among the
shortest when compared to other systems. The
variety of shapes and finishes available on the
market is one of the most significant advantages
of sandwich panels as a construction element.
Depending on the building, various types of
panels are available. The finishes range from
rustic to modern, with imitation wood and
imitation tile panels among others.

WHAT ARE SANDWICH PANELS USED FOR, AND WHAT
VARIETIES ARE AVAILABLE?
The insulation board is typically 1,000 mm wide,
but in some models, it is 1,150 mm wide. The
length of the sandwich panel can be adjusted to
meet the needs of each project, with the most
common dimensions being 3 to 6 metres, but in
some cases, a maximum length of up to 16 meters
can be achieved. The thicknesses of these panels
can vary greatly depending on the final
application, with the most common values ranging
between 40 and 150-200 mm thick.

• FACADE SANDWICH PANELS

Sandwich panels for facades have been improved
for use in building enclosures in homes, schools,
hospitals, industrial parks, and shopping malls.
Sandwich panels are also available for interior
partitions that need insulation. The benefits
provided by these façade panels are heavily
dependent on the method of panel joining. The
fastening system is tongue-and-groove, ensuring
adequate protection and preventing heat and
humidity dissipation.

• ROOFING SANDWICH PANELS

Sandwich panels for roofs differ from façade
panels in that they must withstand large amounts
of snow, rain, and other climatic factors. They
are fastened to the structure with self-drilling
screws to prevent leakage in the event of rain or
humidity and are frequently combined with sealing
joints to expedite installation without
sacrificing the insulation layer.

PANELS THAT ARE REFRIGERATED
Sandwich panels can also be used as insulation in
cold rooms or freezers. In these cases, the
sandwich panel is made thicker than usual in
order to withstand negative temperatures. Special
attention must be paid to the joints between the
sandwich panels in order to maintain the extreme
temperatures required for the preservation of
fresh food products.

PUR and infrared panels
Sandwich panels provide excellent insulation
while being the thinnest. Because of their
excellent insulating capacity and mechanical
properties, they are an ideal ally for industrial
construction. On the market, there are two types
of polyurethane panels PUR (polyurethane foam)
and PIR (polyisocyanurate foam), both of which
provide excellent thermal insulation, with the
latter providing the best fire performance. Since
2014, White metal has provided polyester polyols
and systems based on recycled PET for the
production of sandwich core insulation panels
with PIR technology. All of this means that
Synthesia Technology, with its extensive
experience in this field, is committed to
recyclable, sustainable, and ecological
materials, thereby fostering the creation of a
circular economy for the future. Source
