Construction wall, ceiling elements

The structural elements of a building consist of the envelope elements (external walls, floors, ceilings, roof) and internal constructional elements (internal walls). All these opaque (not light transmitting) elements are referred to as walls in this section. Translucent elements are referred to as windows. 

The fully developed fire is affected by (a) the size and shape of the enclosure, (b) the amount, distribution and type of fuel in the enclosure, (c) the amount, distribution and form of ventilation of the enclosure and (d) the form and type of construction materials comprising the roof (or ceiling), walls and floor of the enclosure. The significance of each phase of an enclosure fire depends on the fire safety system component under consideration. For components such as detectors or sprinklers, the fire development phase will have a great influence on the time at which they activate. The fully developed fire and its decay phase are significant for the integrity of the structural elements. 

When use of SWP by the construction element is considered, most of it is applied externally (as external walls and facades, 56%), followed by roof insulation (30%) and for ceilings, internal and partition walls (14%). SWP can also be installed as wall panels with integrated windows, for various indoors separations, as acoustic roof panels and as construction accessories (variable connecting SWP panels to connect individual wall and roof panels) and in prefabricated housing and shelters.
