Thermal Conductivity Of Wooden Floor

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.

Thermal conductivity of wooden floor.

The thermal conductivities differed according to the structure of the floorings. Laminate wood flooring exhibited the highest thermal. 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. For example the thermal conductivity of pine in the direction of the grain is 0 22 w moc and perpendicular to the grain 0.

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. Engineered parquet are usually laid on the heated base for good thermal conductivity. Thermal conductivity of wooden floors in the context of underfloor heating system applications 147 table 1. The thermal conductivity of wood is relatively low because of the porosity of timber.

One coating was 0 2 mm thick because of an additional overlay. 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. Springer link feb 6 2009.

The thermal conductivity was measured by using the guarded hot plate method. However because marble tiles are usually twice as thick as ceramic tiles they offer greater protection against thermal conductivity. The thermal conductivities differed according to the structure of the floorings. However the type of underlayment used with a wood floor can increase the overall r value considerably.

Tile floors such as marble and ceramic offer similar r values when compared based on the measurement. Details of analysed flooring elements no. The reverse side of each laminate flooring was not melamine but phenolic faced. Thermal conductivity and water vapour transmission.

Laminate flooring and solid wood flooring have high density as they are made of high density fiberboard hdf and thick solid wood respectively. The heat conduction rate is λ 0 15 0 17 w m 2 k depending on the thickness of parquet. With a hdf substrate here. The average thermal conductivity is as follows.

The thermal conductivity was measured by using the guarded hot plate method. When installing an underfloor heating system with a wooden floor thermal conductivity is an important factor to think about. Thermal conductivity declines as the density of the wood decreases. In the direction of the grain the thermal conductivity of wood is about twice what it is perpendicular to the grain.

Ensure the wood is as dense as possible for greater thermal conductivity.
