Thin Insulating Sustainable Application for Building Envelope. Wrapping For Better Energy-efficient Buildings

Over the past few years, energy consumption in the building sector has increased internationally, therefore the Net Zero Energy Building (NZEB) principle has become a feasible possible option for improving efficiency and reducing energy usage in buildings. However, building materials with energy-saving properties play a crucial role in achieving the NZEB objective and are becoming highly important in the building industry. To obtain energy savings in the building sector, the real challenge is to retrofit existing constructions. In addition, the application of conventional thermal insulation can be complex and critical specially in retrofitting old and historical buildings with restricted spaces. Moreover, the other significant factors for many users are accessibility, and affordability, and time- consuming of implementing of conventional insulations. The objective of this research is to identify and achieve an innovative form of thin reflective multilayer insulation that can transmit low possible heat transfer, achieving maximum efficiency with the minimum possible thickness that occupies the minimum possible area in existing construction, while providing users with affordable low-cost material solutions compared to existing conventional insulating materials. Thermal conductivity of all insulations including thin reflective multilayer insulation was measured by the Infrared thermography method. It was also evaluated according to the same conditions and environment.
