PRINCIPLE OF RADIANT HEAT BARRIERS:

The bright surface of aluminium foil has the ability not to absorb but to reflect 95% of the infra-red rays which strike-it. Since aluminium foil has such a low mass to air ratio, very little conduction can take place, particularly when only 5% of the rays are absorbed. The amount of radiation emitted is a function of the emissivity factor of the surface.

Emissivity is the rate at which radiation (Emission) Is given off. Absorption of radiation by an object Is proportional to the absorptivity factor of its surface which is reciprocal of its emissivity:

Silair Radiant Shield blocks radiant heat transfer that faces an air space, upto 95 % of heat radiating down from a hot roof.

Conventional types of insulations, consisting of fibers or cells entrap air or contain a gas to retard heat conduction. For these types of insulations the ability to reduce conductive and radiant heat transfer is determined by their 'R'-value. Non-solar heat is often measured by terms as 'U' value i.e. energy measured in watts per sqm. per degree of temperature difference.

Radiant barriers reduce only radiant heat transfer.

Silair Radiant Shield provides a polyethylene bubble pack between two foils on either side which further restricts the flow of heat from either side during change of atmospheric conditions which alter the direction of heat flow.

INSTALLATION:

Reflection and Emissivity by surfaces can only occur In space. The ideal space b any dimension 20 mm or more. Smaller spaces are effective, but decreasingly so. Where there is no air space, we have conduction through solids. When a reflective surface of a material is attached to a ceiling or wall, that particular area ceases to have radiant Insulation value at the points in contact.

The placement of the radiation barrier shall be in a manner to allow an air space below the roofing sheets or between vertical cladding. The hotter the climate, the more beneficial the radiant barrier installation becomes.
