Fire safety in buildings is one of the basic requirements for construction products in the EU Construction Products Regulation, CPR.

Fire safety in buildings primarily concerns personal safety, but also includes the protection of material values. Data from fire accidents indicates that smoke and toxic gases cause the majority of deaths. Smoke and toxic gases kill long before the temperature has risen or flames have developed. Consequently, the main design requirement from a personal safety perspective is that buildings are constructed and configured to ensure that people can get to safety and the emergency services have the capacity to respond in the event of a fire.

The requirements for the materials used and the structures are determined by the building use, size, fire load and operation. Fire safety requirements in the national building regulations are often based on fire development (standard fire curve).

This information is intended for builders and architects and is a guideline only. Please contact your planning officer and/or your fire officer before proceeding with your project.

Fire Classifications

Fire safety requirements in the national building regulations are often based on fire development (standard fire curve). The requirements for the materials used and the structures are determined by the building use, size, fire load and operation.

Euro class Example
A1, A2 Stone wool, gypsum board
B Painted gypsum board
C Gypsum board with paper-based wallpaper
D Wood
E Fire-retardant EPS
F Non-tested materials, EPS
Additional classes for smoke development
s1 the structural element may emit a very limited amount of combustion gases
s2 the structural element may emit a limited amount of combustion gases
s3 no requirement for restricted production of of combustion gases
Additional classes for smoke development
s1 the structural element may emit a very limited amount of combustion gases
s2 the structural element may emit a limited amount of combustion gases
s3 no requirement for restricted production of of combustion gases

Class A1 is non-combustible and the requirement level and cannot be combined with any additional class.

Class A2 is also classified as non-combustible as no flashover occurs for the application of the products in these classes.

For classes A2 to D there are additional classes for smoke development s1, s2 or s3, and the amount of burning droplets emitted d0, d1 or d3 (e.g. A2-s1, d0).

Class E only has additional class d2.

Class F means that the product is not documented, the product does not meet the criteria for any class, or the manufacturer has not provided the fire properties for the product. Class F cannot be combined with any additional class either.
Fire classification of buildings

At the beginning of a construction project, during the planning phase, the designer must determine the operational and building technical class that the building must comply with. In many cases there is no alternative, but sometimes you can choose from multiple classes.

Teckwood’s wood plastic composite cladding carries a classification of B-s2,d0.

Teckwood’s wood plastic composite luxury vinyl flooring carries a classification of B-s1.
