Energy efficiency

Energy efficiency

Sandwich panels contribute to the energy efficiency of a building by saving energy to maintain a particular indoor climate and minimize maintenance costs over a long period of time. Thanks to the basic sandwich panel solutions from Technopanel, you can increase your building's LEED and BREEAM ratings as well as significantly reduce your heat and CO2 costs.
Thermal Insulation

Thermal Insulation

Sandwich panels have qualities at times higher than those of traditional building materials and fully meeting, and in many cases, exceeding the regulatory requirements for construction of different types of buildings. The excellent thermal insulation provided by the core of the panel and the density between the joints contribute to the high insulation efficiency provided by relatively thin sandwich panels. Polyurethane (PUR) has excellent thermal insulation properties and the lowest thermal conductivity of all commonly used insulation materials.
Mineral wool (MW), on the other side, is a non-combustible material and has excellent sound absorption properties. The polyisocyanurate (PIR) comes with the advantages of the polyurethane – already known and accepted material with extremely low weight, high structural strength, inherent adhesion to metal and excellent thermal insulation properties. In addition the cyclical ring structure of polyisocyanurate shows higher thermal stability, resulting in improved performance properties for both reaction to fire and fireproofing.

Therefore, it is possible to achieve high insulation performance with relatively thin sandwich panels. Their good thermal insulation properties are due both to the excellent performance of the insulation core and to the tight and precise joint connection between the panels.

One of Technopanel's main priorities is the quality of our products. To guarantee innovative products, we are committed to the continuous improvement of our technology. According to the findings of leading European experts, buildings constructed with thermal insulation panels are considered environmentally friendly. Both the sheet metal and the cores of the panels are recyclable materials. The cores have zero potential for ozone depletion and practically zero potential for contributing to global warming.

Aesthetic advantages

Aesthetic advantages

Sandwich panels give an aesthetic finish to buildings and their metal surfaces are easily combined with other materials. The structural applicability and height of the buildings are unlimited and the geometry of the buildings is limited only by the supporting structure. We can offer large color palette - 14 standard RAL colors and many additional special colors and decorative imitations. Thanks to sandwich panels’ application flexibility, the buildings could be easily expanded and renovated without serious interruption of the building activities. In principle there are no technical or economical limits to the complete movement of a building.

Saving space

Saving space

Sandwich panels are used for facades, roofs, partition refrigerators, partitions and ceilings.
Because of its thin wall construction, external and internal walls take up much less surface area with sandwich panel construction than with the solid method of construction. For the same thermal transmittance value (U), the sandwich panel is much thinner than a solid wall. For this reason, it is realized a measurable increase in the proportion of useable area to the total covered area when compared to the solid method of construction. To achieve the U=0.3(W/m2K) a polyurethane cored sandwich panel would need to be 80 mm thick, a rock wool cored sandwich panel – 100 mm thick, while a solid wall would need to be 365 mm thick with inside and outside plaster as well as additional 80 mm of external insulation. This wall structure leads to a total thickness of 465 mm.

Expenses and depreciation

Expenses and depreciation

Material and assembly expenses of construction with sandwich panels are similar to the alternative construction methods. But if operational and maintenance expenses are considered, sandwich panels have undoubted advantages which increase on account of energy saved. The design and structure of sandwich panels allows easier achievement of roof and wall enclosure impermeability compared to other solutions. Sandwich panel enclosing feature much less own weight compared to alternative methods which is leading to decrease of bearing structure expenses. Sandwich panels stand out with their very low maintenance needs. The high quality coating guarantees long-term corrosion protection.
