Thermal Conductivity Of Wooden Floor

The thermal conductivities differed according to the structure of the floorings.

Thermal conductivity of wooden floor.

The average thermal conductivity is as follows. Laminate wood flooring exhibited the highest thermal conductivity because of its high density and thin layers compared to the other floorings. The thinner and denser the wood the quicker the heat up time. Thermal conductivity of wooden floors in the context of underfloor heating system applications 147 table 1.

When installing an underfloor heating system with a wooden floor thermal conductivity is an important factor to think about. The thermal conductivity and transfer performance of 21 replicates of wood flooring materials generally used in korea were measured. Thermal conductivity is a material property that describes ability to conduct heat thermal conductivity can be defined as the quantity of heat transmitted through a unit thickness of a material in a direction normal to a surface of unit area due to a unit temperature gradient under steady state conditions. Ensure the wood is as dense as possible for greater thermal conductivity.

The thermal conductivity of wood is relatively low because of the porosity of timber. The reverse side of each laminate flooring was not melamine but phenolic faced. The heat conduction rate is λ 0 15 0 17 w m 2 k depending on the thickness of parquet. In the direction of the grain the thermal conductivity of wood is about twice what it is perpendicular to the grain.

An engineered parquet might be glued to a wooden base or straight on the concrete using a special glue. Laminate flooring 0 115 w mk solid wood flooring 0 112 w mk modified engineered flooring 0 111 w mk engineered flooring 0 104 w mk. Laminate wood flooring exhibited the highest thermal. Thermal conductivity and water vapour transmission.

For example the thermal conductivity of pine in the direction of the grain is 0 22 w moc and perpendicular to the grain 0. With a hdf substrate here. However the type of underlayment used with a wood floor can increase the overall r value considerably. Code type and thickness of flooring elements cross section 1 a solid wood 22 mm oak 2 b three layer 14 mm oak 2 5 mm pine slats 9 0 mm.

Engineered parquet are usually laid on the heated base for good thermal conductivity. Table 1 shows the thermal conductivity of all wood based materials. Thermal conductivity declines as the density of the wood decreases. The thermal conductivity was measured by using the guarded hot plate method.

Laminate flooring and solid wood flooring have high density as they are made of high density fiberboard hdf and thick solid wood respectively. Tile floors such as marble and ceramic offer similar r values when compared based on the measurement. Springer link feb 6 2009. The thermal conductivities differed according to the structure of the floorings.
