In public spaces where many people gather to meet, the importance of fire safety accentuates. Naturally, the fire classes required of materials are also more stringent. We test our solutions thoroughly. For example, the fire classes of our panels have been tested by Eurofins Expert Services. We can therefore offer products with the highest fire classifications on the market.
Depending on the fire safety requirements of a space, different weightings have to be considered when choosing materials. One option is to use a fibreboard as background material for spaces with the highest fire classification needs. MDF, on the other hand, is a lighter alternative to fibreboard. In addition to lightness, MDF has the advantages of easier perforability and flexibility. If the architect has drawn curved forms in the building, the materials also need to flex. This allows deviations from the fire classifications on certain surfaces. Our architect service has a solid understanding of the challenges of different spaces and the fire safety of surface materials - we can help you find the most suitable solution for your project.
Building materials are divided into classes depending on how they influence the ignition of fire, the spread of fire, and the production of smoke. EN standards are used as test methods and for classification. Fire classification for building products is made according to classification standard EN 13501-1.
The main classes for building materials (excluding flooring) are described using the following symbols: A1, A2, B, C, D, E, F.
Smoke generation and formation of droplets is expressed using the additional classification s and d. The classification of smoke production is s1, s2, s3 and of formation of droplets d0, d1, d2.
The results of the test methods for the main fire classes, EN ISO 1182 (non-combustibility) and EN ISO 1716 (calorific value), are not dependent on the way the product is installed and fixed.
Depending on the use case there's a variety of solutions to choose from. Here are the most common of those.
The super-safe, practically incombustible veneered interior panel in the A2 fire class is a high-tech solution developed first in Finland by Puucomp to meet the needs of demanding use.
The fire class A2-s1-d0 indicates excellent fire resistance and these kinds of panels are required in such places as the interior surfaces of building exits and stairwells.
Puucomp A2-s1-d0 -fire classification means that:
For many spaces, an interior panel in the B fire class is the right solution. In conventional use, an interior panel in the B fire class only has a small effect on the development of a fire.
Puucomp interior panel B-s1-d0 -fire classification means:
Lath elements are good solutions also regarding fire safety. A2- lath element can achieve A2-s1,d0 -level fire classification.
