Thermal and Acoustic Qualitiesof ONDULINE sheetsThermal and Acoustic Qualitiesof ONDULINE sheets

1) Thermal qualities :

• Thermal conductivity : λAbility of a material to conduct HEAT

• Thermal resistance : R Ability of a product to reduce HEAT conduction

(most of the time heat transmission coefficient K=1/R is recorded)

Examples (materials):• Expansed Polystyrène : 0.034 W/m.°C• Cork : 0.1 W/m.°C• Bitumen : 0.17 W/m.°C• Wood (pin): 0.36 W/m.°C• Fiber cement : 0.95 W/m.°C• Brick (Clay) : 1.15 W/m.°C• Reinforced concrete : 1.75 W/m.°C• Iron : 52 to 80 W/m.°C

Thermal conductivity λ :(Ability of a material to conduct HEAT)

The lower the λ value is, the lower HEAT

conduction will be.

Listen & compare

Customers testimonies :

Comfort Roof - Impact noise Absorption

No “drumming” effect at all under tropical rain

Onduline material being 3mm thick and relatively soft, sound of tropical rain is greatly reduced; there is no “drumming” effect at all
