The building area is also called the building expansion area, which refers to the plane area of each floor measured on the peripheral horizontal plane above the foot of the exterior wall of a residential building. It is an economic indicator indicating the size of a building. The building area of each floor is calculated based on the horizontal section of the outer wall above the feet of the building. It includes three items, namely usable area, auxiliary area, and structural area. In mainland China, the regulations related to building areas include the "Rules for Calculation of Commercial Housing Sales Area and Allocation of Public Building Area" and the current "Rules for Calculation of Building Area". In Hong Kong, China, the calculation of building area and usable area must follow the "Code of Measurement Practice" issued by the Hong Kong Institute of Surveyors. In Taiwan, and China, there are construction technical regulations, and the volume control in Chapter 9 is the regulations on floor area ratio and building area.
The main difference between exterior wall insulation fiber mesh cloth and interior wall mesh cloth is the material.
Exterior wall insulation mesh cloth is generally made of medium-alkali or alkali-free mesh as raw materials, and then is applied in multiple layers and finally dried to form an alkali-resistant mesh cloth. This kind of product is very stable and strong, and it is also simple and easy to implement during our construction. Then its purpose is to effectively enhance the tensile strength of cement and wall buildings.
The mesh cloth for the interior walls is made of glass fiber as the main raw material and is made through multiple processes. This kind of interior wall mesh is an ideal material for GRC wall panels.
The unit weight of interior wall insulation mesh cloth is generally relatively light, usually around 50-60 grams, and the tensile strength of the mass is relatively small. The unit weight of exterior wall insulation mesh cloth is generally 80 grams. Depending on The type of building and the number of grams used are also different. It is better to use it on the exterior wall to resist tensile strength.
