PIR/PUR multilayer panels are advanced insulating materials used in construction for insulating roofs, walls, and floors. Their structure ensures effective protection against heat loss while providing resistance to moisture and mechanical damage. These panels consist of multiple layers, including a core made of polyisocyanurate (PIR) or polyurethane (PUR) foam, surrounded by external protective coatings. This article will discuss the structure of a PIR/PUR multilayer panel's cross-section,...

Steel purlins are structural elements used in roof construction, designed to transfer loads from the roofing to the truss. Their proper placement is crucial for the stability of the entire structure and ensuring safety. When planning the layout of purlins, many factors need to be considered, such as the roof span, loads, or the type of material. Steel purlins are available in the offer of e-PROJECT21. Let’s take a closer look.

Modern construction focuses on solutions that combine speed of execution, durability, and cost efficiency. In this context, steel purlins for construction systems are gaining increasing popularity, offering numerous advantages that contribute to optimizing the construction process and achieving high-quality structures. Steel purlins are thin-walled steel profiles with an open cross-section, most commonly in the shape of the letter C or Z. Thanks to their specific design, they are...

Skirting boards made of galvanized sheet metal coated with a polyester layer are increasingly chosen for outdoor applications. This is due to their exceptional properties, making them an ideal solution for protecting and finishing buildings.

Steel C profiles are versatile structural elements widely used in construction, especially for the installation of sandwich panels. They are characterized by high strength, light weight, and ease of installation. Thanks to their specific shape, resembling the letter "C," these profiles offer excellent load-bearing properties, making them an ideal solution for the construction of walls, roofs, and other building components. Their versatility makes them a key element in modern industrial and...

There are materials on the market that can be used for constructing various types of facilities. Examples include PIR and PUR sandwich panels designed for cold stores and freezers. These panels are characterized by high gas tightness, resistance to mechanical damage, as well as moisture and fire resistance. What distinguishes these two types of panels from each other? Where can they be purchased? Read on!

Simple, practical, and enhancing the aesthetics of the exterior façade. It’s no surprise that shelters are so popular. However, before construction, they need to be properly designed, and steel profiles are commonly used for this purpose. Which ones should you choose?

This question has often been asked by people looking for information on the most popular methods for finishing garage roofs. Depending on the needs, sandwich panels with a core made of polyurethane foam (PUR) or polyisocyanurate foam (PIR) are most commonly used. Both types have similar properties, but there are some differences between them. What are they? Read on!
