Abstract
The paper focus of the influence of the climatic conditions on thermal state and heat transfer of the frame partitions insulated with loose wood wool. While it is well known that building materials change thermal conductivity depending on the operating temperature, the always question is how much it influences on the whole element. The paper presents the laboratory results from the hot box chamber investigation of the frame partition. These results are compared with the simulation results.
Highlights
Fibrous materials are characterized by good thermal properties and their great advantage is the possibility of using them as batt but as loose and bulk materials as well
Fibrous materials are characterized by high porosity, which increases with decreasing their thermal conductivity
This leads to an increase of air permeability, which may result in a counterproductive effect - natural convection in the material that leads to increased heat transfer in insulation
Summary
Fibrous materials are characterized by good thermal properties and their great advantage is the possibility of using them as batt but as loose and bulk materials as well. This means that they can be used to insulate almost each space except for places that are constantly wet, work is being carried out on the drying capacity of fibrous materials, cellulose fibers [1]. Fibrous materials are characterized by high porosity, which increases with decreasing their thermal conductivity This leads to an increase of air permeability, which may result in a counterproductive effect - natural convection in the material that leads to increased heat transfer in insulation. Particular attention should be paid to the protection of fiber insulation against air filtration
