FLOORING INSULATION OVER CELLARS, ARCADES AND NON-HEATED AREAS IN GENERAL

This type of flooring disperses heat coming from heated rooms above. The correct form of insulation, from a physical point of view, is on the surface beneath. This avoids condensates, keeps the floor above warm and maintains the cellar cool.

IN NEW BUILDINGS: 

Celenit panels are used as a permanent formwork in on-site flooring casting or in the insulation of Predalle-type prefabricated floorings. When used this way, the panels can be left visible. Furthermore, the ceiling is ready after the dismantling stage, and can be painted or left its natural colour. The non-plastered panels carry out their function to the full as insulators against sounds produced on site (cars, boilers, noisy games, etc) and as fire retardants. They allow the user to save on the cost of plaster while still obtaining a pleasant visual effect. 


IN EXISTING BUILDINGS:


a) the panels are fixed with screws or nails to wooden laths fixed to the ceiling, spacing being equal to the width of the panel. The space between the laths can be filled with other insulators.
b) the panels are fixed directly onto the ceiling using screw anchors.
c) as regards open spaces, such as arcades in residential buildings, car parks, etc, where excessive flooring heat dispersion and low floor temperatures can create discomfort to those living in the apartments above, acoustic and thermal insulation is achieved by mounting the panels on a framework of metal profiles.

HEATED CELLARS - WALL INSULATION

The walls of a cellar, which are generally made of reinforced concrete, must be insulated if the room is to be used. A very advantageous method of insulation consists in using panels as a permanent formwork on the internal and external surfaces, or even just on the internal surface if the room is only used occasionally. The external panels are to be treated with waterproofed mortar and covered with waterproofing membranes. Furthermore, it is advisable to use a layer of panels in order to prevent loose earth from scattering towards the scree placed as a protection of the wall. In existing buildings, the panels are fixed to the walls from the inside, using screw anchors.

Figure 2: Celenit N panels painted white are used here as permanent formworks in the first flooring casting: thermal insulation, noise absorption, fire protection, unlimited duration.

Figure 3: Cellar of a one-family house: the first flooring is a predalle, insulated with 35mm Celenit N panels: acoustic and thermal insulation, some amount of finishing required. The wall was subsequently insulated with 35mm Celenit P3 panels applied with screw anchors.

FLOOR INSULATION


In order to avoid excessive dispersion groundwards, the floor along the ground must be insulated. The panels are sunk in the floor casting or, in existing buildings, are placed on the floor with joggled joints and treated directly with the floor setting mortar.
