� Thermal Conductivity, K value λThermal conductivity is the amount of energy (heat flow) that passes a material with thickness of 1 m, size of 1 m2 and temperature difference on both sides of the material of 10Cλ K value measured in W/mK

� Thermal Transmittance, U valueThermal transmittance is the rate of transfer of heat (in watt) through 1 m2 of material or structure divided by the difference in temperature across the material or structureU value = 1 / R – measured in W/m2K

� Thermal Resistance, R valueThermal resistance is the measurement of temperature difference, at steady state, between 2 defined surfaces of a material or structure through a unit area, in which the material resist heat flow.R value = t / λ (t / K) - measured in m2K/W where t is thickness

EFFECT of WATER ABSORPTION

Degeneration of roof framing

High water absorption insulation material

• Corrode the steel framing

– rust can breed tetanus & inhalation of rust particles can cause

lung injury.

• Cause timber frame to decay

– promote growth of fungi and mold.

Growth of fungi and mould

• High water absorption insulation material would promote growth of fungi and mold

Roof spaces – for a roof structure consisting of a flat, uninsulated ceiling and pitch roof, the roof space

may be regarded as if it were a thermally homogeneous layer with a thermal resistance as given in the

following table.

3.10. Reflective Foil Products

3.10.1 Bubble sheet with aluminium foil facingThe thermal resistance (R value) of bubble sheet with foil facings consists of the resistance of the bubble sheet

and the resistance of air spaces on either one side of it or both sides where the resistance of air space(s) takes

account of the emissivity of the surfaces.

3.10.2 Multi-foil insulationMulti-foil insulation comprises products that consists of several layers of foil separated by other materials.

They are intended for applications with an air space on either side and the overall thermal performance includes

the effect of low emissivity surfaces facing these air spaces

4.8. Airspace Resistance

4.8.2 Unventilated airspaces, low emissivity surface

Low emissivity surface (e.g. aluminium foil) has no effect on the U value if not adjacent to an air space in the

construction.


22

BRE 443

For tiled faced products, with the foil adjacent to an unventilated airspace of

width at least 25 mm, the thermal resistance of the airspace may be taken as :

Low emissivity surface, heat flow horizontal (wall) 0.44 m2K/W

Low emissivity surface, heat flow upwards (roof) 0.34 m2K/W

Low emissivity surface, heat flow downwards (floor) 0.50 m2K/W

Insipient/Ignition – combustion begins

Growth – flaming combustion of an item, spread of fire

Flashover – condition in compartment changes to combustion/ignition of all exposed surface

Fully developed – all items/materials in compartment are alighted, maximum heat release

Decay – gradual decrease of fire due to decrease in fuel

75% of all fire deaths are caused by smoke inhalationSource: Hall, Jr. John R. NFPA Fire Analysis & Research, Quincy, MA. “Burns, Toxic Gases,

and other Hazards”.

Approximately 57% of people killed in fires are not in the room of the
