Thermal Conductivity Of Insulation Materials

The range of building materials used in construction continues to expand across various applications. This growing diversity underscores the need for making well-informed assessments regarding the properties of different materials and their adherence to standards. The scrutiny of building materials, including the evaluation of thermal conductivity in insulation materials, serves not only to ensure compliance with relevant laws and regulations but also to establish documented safety standards, thereby reducing liability risks for all stakeholders involved in construction projects.

Simultaneous Thermal Analysis (STA) proves to be highly suitable for the investigation and characterization of the thermal properties of building materials, including concrete, cement, mortar, and other mineral-based construction materials. STA allows for the analysis of critical factors such as the glass transitions of modified glass, binder burnout, decomposition behavior, cement hydration levels, and expansion and shrinkage tendencies.

One notable advantage of STA, in comparison to separate devices, lies in its capability to measure weight changes and calorimetric reactions simultaneously when evaluating the thermal conductivity of construction materials. The use of identical experimental conditions, including atmosphere and heating rate, for both thermogravimetry (TGA) and differential scanning calorimetry (DSC) results in considerably more precise examination outcomes, offering a wealth of valuable information for assessing the thermal properties of construction materials.

Dilatometry, on the other hand, offers crucial insights into the expansion and shrinkage behavior of building materials during their production and when deployed in their final location.

The determination of thermal conductivity in building materials using a HFM-Heat Flow Meter has become increasingly vital as the demand for insulation materials and energy-efficient solutions rises. It is for these reasons that many in the industry place their trust in Linseis for instrumentation used in the thermal analysis of construction materials.
