Manufacture and Design an Apparatus for Measuring the Thermal Resistance of Building Materials

A good thermal design of buildings plays a key role in reducing the loads heating and air conditioning systems thus energy consumption. This study develops steady-state apparatus for measuring resistance building materials by using an absolute technique. The is designed to accommodate full actual size tested samples used Syrian market ease testing. Therefore, suitable do not have be built apparatus; measured many samples, results are compared with insulation code Arab Republic. show that difference between values obtained from experiments due local markets their non-compliance code. These need testing quality control during manufacturing process.
