Provided is a system and method for a providing exterior insulation and finishing for a building. More specifically, the system for providing exterior insulation and finishing for a building, includes: backing material to be affixed to an exterior wall structure, the backing material suitable to receive closed cell spray foam; a reservoir of closed cell spray foam to be applied by a sprayer to the backing material when adjoined to an exterior wall surface; at least one shaping device structured and arranged to shape the closed cell spray foam after application to the wall surface; and a reservoir of weather resistant barrier material to be applied by a sprayer to the shaped closed cell spray foam. An associated method of use is also provided.

The invention discloses an assembly type negative pressure isolation chamber, in which the necessary configuration of the negative pressure isolation ward is contained in a hexahedral chamber. The chamber forms an independent building assembly unit, which can be integrated into or removed from the building system. The chamber can also be disassembled and transported, and the switching of use functions can be realized through the flexible combination and simple modification of components. The indoor wall of the chamber is light Clean and washable materials are integrated with furniture. The air conditioning system adopts internal circulation return air and independent temperature regulating device. The sewage pre disinfection link is added to the sewage system. The negative pressure isolation chamber can help the medical isolation building system expand rapidly in case of respiratory infectious disease outbreak and can carry out space mobility with the transfer of the epidemic situation.

The present invention relates to the creation of thermally insulating materials derived from cellulosic materials by selectively depolymerizing the materials anatomy. Cellulosic materials may be comprised of three main biopolymers: lignin, hemicellulose, and cellulose. The present invention relates to the chemical and physical removal of lignin and hemicellulose, while leaving the cellulose unaltered to induce increased porosity within the material and the material’s macrostructure matrix for use as thermal and acoustic insulation. The increased porosity will be due to the creation of closed cell voids within the cellulosic matrix. These voids will increase the thermal and acoustic insulating performance of the cellulosic materials. The selective removal of secondary biopolymers from cellulosic materials allow for isolation of other value added products that can be regenerated through fewer reactions/steps. This is a novel advantage over other similar processes that dissolve cellulose completely, making it harder to extract and isolate secondary off-stream products.
