In modular buildings, the insulated sandwich panels used in walls and ceilings have excellent structural stability. These sandwich panels are formed by covering an insulating core with metal sheets, and they also possess some unique advantages in buildings such as warehouses, factories, hotels, poultry houses, etc.

When there are different types of sandwich panels available for selection – PUF (polyurethane foam), PIR (polyisocyanurate), EPS (expanded polystyrene), etc. –What is the reason that PIR panels have become the most popular choice in construction.

PIR is what?

PIR is in short of polyisocyanurate,one of the most thermally efficient insulation materials available in the industry.PIR is a thermosetting polymer material that combines isocyanates and polyols. This means that it will not melt when heated. Depending on the manufacturing process and the standards , the quality and performance of PIR may vary. That's why it's important to check the required certifications when making a choice.

PIR panel is what?

Of course PIR sandwich panel is in short of polyisocyanurate sandwich panel, consist of three layers: a high-density rigid polyisocyanurate foam, which is covered on both sides with a galvanized or aluminum plate coating.

These PIR panels have excellent thermal insulation properties, as well as the capabilities to bear mechanical loads and high wind speeds, so they can be used as building materials in buildings that require high fire resistance. In fact, its thermal conductivity is lower than 0.023 W/(m·K).

PIR panel advantage is what? 

☆Excellent Thermal Insulation Performance

PIR panels, with thermal conductivity < 0.023 W/(m·K), reduce heat transfer, stabilize indoor temps, cut heating/cooling energy use, and lower utility bills.

☆High Fire Resistance

PIR, a thermosetting polymer, has good fire - resistant properties. PIR panels slow fire spread, aid evacuation, and suit fire - safety - crucial buildings.

☆Good Mechanical Properties

PIR panels possess strong mechanical strength, endure loads and high winds, and maintain building stability in diverse conditions.

☆Moisture Resistance

PIR panels' great moisture resistance stops moisture, averting mold, corrosion, and extending building & component service life.

☆Lightweight

PIR panels' lightweight nature eases transportation, installation, reduces building weight, benefits foundations, and boosts construction efficiency.

☆Long Service Life

Due to stable chem props & env resistance, PIR panels have long lifespan, need less replacement/maintenance, and save long - term costs.

☆Versatility

PIR panels are versatile for building applications, customizable in size/thickness, providing flexibility in design and construction.

PIR panel application is what?

☆Building Envelope Systems

Walls: PIR panels, used in exterior walls, offer thermal insulation, cut heat transfer, and enhance building energy efficiency in new or retrofit projects.

Roofs: PIR panels, ideal for roofing, offer thermal resistance, work on various roof types, and protect against moisture damage.

Floors: PIR panels are used in floor insulation, crucial for thermal comfort in basements and upper floors, and also help cut inter - floor noise.

☆Cold Storage Facilities

 PIR panels, popular in cold storage, maintain low temps, cut fridge energy use, and form insulated parts for storage needs.

☆Industrial Buildings

 In industry, PIR panels insulate factory buildings, workshops & warehouses, offer strength, and benefit workers & stored items.

☆Prefabricated Buildings

PIR panels are favored in prefab/modular building. Their light weight eases transport/assembly, cutting time & costs while providing insulation.

☆Clean Rooms and Laboratories

 In clean rooms and labs, PIR panels ensure thermal stability, blocking heat & moisture for equipment and experiments.

☆Marine and Transportation

 In marine and transport, PIR panels insulate ship areas, trucks & trailers, offering heat control and fire safety.

☆Acoustic Insulation Applications

PIR panels, though mainly for heat, also aid acoustic insulation, reducing noise in studios, offices, and noisy - area homes.

So PIR panels are preferred in modern construction due to their excellent insulation, strength, versatility, and cost - effectiveness.
