In the budget for insulation work, there are two items: “Auxiliary project for metal sheet protection layer – steel strip installation” and “Installation of metal sheet nails”. The unit of measurement for both of these items is square meters. What areas do these refer to respectively? {:2_30:}
It refers to the area of the insulation layer (insulation material).
Surface area-----Area of the thin plates used for insulation
External surface area of the insulation layer, comprehensive consumption per square meter
When signing the contract, it’s possible to ignore these losses; one can simply specify the surface area in square units, with all requirements regarding steel strips, screws, etc. already taken into account.
You can check the relevant standards, which contain the corresponding requirements
