The present invention relates to an acoustical and thermal decoupling system (10) in a form of a polymer tape that includes a closed-cell foam layer (12) having a front side and a reverse side, a pressure sensitive adhesive (14) coated on the reverse side of the closed-cell foam layer (12), and a release liner (16) covering the pressure sensitive adhesive (14) on the reverse side of the closed-cell foam layer (12). The acoustical and thermal decoupling system (10) may be installed directly to a structural member of a building by removing the release liner (16) from the reverse side of the closed-cell foam layer (12) and pressing the reverse side of the closed-cell foam layer (12) against the structural member, allowing the pressure sensitive adhesive (14) to bond the closed-cell foam layer (12) directly to the structural member.

A structure system that enables heat, sound and moisture insulation without having a thermal bridge and has its own load-bearing elements, and a production method is disclosed. The structure system has at least one main load-bearing system, and at least one filling material that partially or completely surrounds the main load-bearing system and has an insulating feature. The production method of the structure system has the steps of placing the main loadbearing system in at least one mould in a way that there is a space between the main load-bearing system and the surfaces of the mould, wherein the filling material does not adhere to the mould and the mould limits the filling material so as to shape it, filling and drying the filling material in the space so as to partially or completely surround the main load-bearing system, and removing the mould after the drying process is completed.

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.
