Wood is an incredibly important material, it has been used in building construction, furniture making, for fuel, and in many other applications throughout history. Today, wood is still seen as a viable, renewable source for many of our construction needs. Understanding the thermal properties of wood is necessary to model thermal transport in buildings constructed with wood, and is crucial to predicting how wood will burn as a fuel. Since wood is a highly anisotropic material, the Hot Disk TPS is an ideal instrument to test the thermal conductivity as it has an anisotropic testing module for this very purpose. The application pages linked below are excellent examples of how the Hot Disk TPS has been used to study the thermal properties of both oven-dried and green wood, and provide an idea of the variety of projects the equipment can be applied to when it comes to timber products.
In this page, we discuss a paper in which six samples of oven-dried birch are tested to determine the effects of anisotropy, density, and porosity on thermal conductivity. Read more here.
The Hot Disk Transient Plane Source (TPS) technique allows for precise thermal conductivity measurement of a huge array of materials ranging in thermal conductivity from 0.005 to 1800 W/m∙K . TPS is capable of measuring bulk and directional thermal properties of solids, liquids, pastes and powders.
Introduction In 1990, Maurice Ward debuted his miraculous invention on the British TV show ‘Tomorrow’s World’ by demonstrating how an easily applied paint could protect an egg from cooking after being heated by a blow torch. To the amazement of all viewers, the egg...
The Building Envelope Insulative paint can be applied to the interior and the exterior walls of a building to increase the thermal insulation. Any structure that separates the outside and the inside of a building is called the building envelope which includes...
