The buildings, according to their use and surface, are divided into fire sectors. Each consists of a space demarcated by walls and ceilings of a certain fire resistance that prevent the spread of fire to other fire sectors.

The Technical Building Code (CTE), through section SI 1 (interior spread), establishes the maximum surfaces per fire sector based on the use of the building. The fire resistance required for the elements that make up each fire sector is reflected in table 1.2 of the CTE.

Compartmentalisation is a very important part of passive fire protection, as it prevents fire from spreading to the rest of the building. The fire is thus confined within the fire sector where it originated.

Objectives:

• Limit the spread of fire by enhancing the existing compartmentalisation.
• Distribution in limited areas to contain any fire that starts therein or, conversely, to prevent an outside fire from entering a fire compartment.
• Limit the spread of fire inside buildings and between adjacent buildings. The construction elements that restrict it must be fire resistant.

Perlita y Vermiculita has different constructive solutions for the compartmentalisation of buildings. A list of these solutions is attached below:

• Vertical sheet division
• Partitions
• False ceiling

The elements intended for compartmentalisation must have the fire resistance required by the CTE (Technical Building Code) for residential and non-residential building, or by the RSCIEI (Fire Safety Regulations in Industrial Establishments) for industrial-type premises.
