THERMO-INSULATING PANELS
Topanel thermal insulation panels are prefabricated construction elements, consisting of two metal facings and an insulating layer of polyurethane foam (PUR), polyisocyanurate foam (PIR), or mineral wool. Also popularly known as sandwich panels, these construction systems ensure efficient thermal insulation, sound insulation, and high fire resistance, depending on the thickness and type of the insulating layer.
Topanel produces thermal insulation panels with support facings made of S220GD/S250GD steel sheet, with a minimum zinc coating of 200 g/sqm, stainless steel (inox), or composite material with fiberglass, adapted to the specific requirements of the project.
The panels are manufactured according to ISO EN 14509 standards, which regulate the performance and safety of sandwich panels, benefiting from all necessary certifications and declarations of conformity. They can be used in a varied range of industrial, commercial, logistics, agricultural, or livestock projects.
TYPES OF TOPANEL THERMAL INSULATION PANELS

PUR & PIR THERMAL INSULATION PANELS
They are construction solutions used for the enclosure or interior partitioning of industrial halls, commercial spaces, logistics centers, or agricultural buildings. Both PUR and PIR panels ensure high-performance thermal insulation, long-lasting mechanical resistance, and fast installation. In addition, PIR sandwich panels have a fire resistance (REI) between 15 and 30 minutes, depending on the foam thickness.

WHAT ARE THE ADVANTAGES OF THERMAL INSULATION WITH MINERAL WOOL SANDWICH PANELS
In addition to thermal insulation and fire protection, mineral wool thermal insulation panels also offer other important benefits:
- Ensure fire resistance ranging between 30 and 240 minutes, depending on the type, thickness, and mounting position of the panel; they have a fire reaction class A2 – s1d0
- Are quick and easy to install
- Offer very good sound insulation
- Are resistant to temperature variations and severe weather conditions
- Can be used for any type of building: industrial halls, commercial spaces, showrooms, cold storage rooms, or even residential homes
HOW ARE THERMAL INSULATION PANELS INSTALLED
PUR / PIR / Mineral Wool thermal insulation panels are fixed onto a secondary structure made of metal profiles (steel), wooden profiles, or onto metal inserts (in concrete) and are joined horizontally or vertically. Overlapping and fixing the panels is done with self-tapping screws. For maximum installation and thermal insulation efficiency, we recommend using thermal insulation accessories produced by Topanel - TOP PLAST skylights, TOP EVAC smoke and heat exhaust ventilation systems (SHEVS), and tinplate profiles made of the best quality galvanized steel.
