The thermal insulation of wood wool is excellent: wood offers a good thermal insulation by nature. The wood wool slab is the aesthetic finishing for a wall or ceiling. To improve the thermal performance we combine our wood wool panels with three types of thermal insulation with which you can fine-tune the thermal insulation to the exact thermal requirements.
Depending on the building application it is important to choose a solution and combine the wood wool boards with either a core of rock mineral wool, grey EPS or PIR.
What is thermal insulation? Thermal insulation is used to make buildings more energy efficient. A good thermal insulation supports lower energy bills for heating and air conditioning. The thermal performance of materials can be determined by looking at: thermal conductivity (lambda value) of the chosen insulation material and thickness.
The RC-value is the heat resistance value of the total construction. This is a sum of all Revenue values of all materials, corrected with, among other things, the influence of thermal bridges (such as wood and metal fixings).
RD is a declared calculation value, which is also called a Rdeclared value. The RD value indicates how great the heat resistance of the insulation material is. This RD only covers the stand-alone product. RD is indicated in the unit m2
RD [m2 K/W] = thickness [m] / λ [W/m.K]
The Rrevenue value is the calculation value of the heat resistance of each layer of which the structure is constructed, including correction factors.
The U- value (former K-value) indicates the thermal conductivity of a construction and is the inverse of the R value (U = 1/R).
The better the insulation package, the lower the U-value.
Formula: U value = λ value / thickness insulation.
The U value expresses the amount of heat that passes per second, per m² and per degree of temperature difference between one side and the other side of a wall or ceiling construction. The U value is also called heat transfer coefficient.
The value indicates the degree of heat conduction of a wall: a high U-value means a thermally poorly insulating wall, a low U-value means a thermally well insulating wall. The unit for the U-value is W / (m² · K).
