Take room measurements using a tape measure or a lesser measuring machine to determine the dimensions. Once you have the dimensions convert them into square meters and divide by the surface area of a standard gypsum board which is 2.88 square meters. I recommend a 9mm Gyproc gypsum board 8ft*4ft*9mm. Make sure you add some few sheets for wastage Because you can get great results with gypsum, you may wonder how much gypsum should be added to clay soil. We did some research so that you can leave out any guesswork. In most cases, you can add 2.2 pounds of gypsum for every 10 square feet. Or, add 40 pounds of gypsum for every 1,000 square feet of soil being amended. 1 lb m /ft 2 = 4.88 kg/m 2 . Note! - the weight of truss/rafter must be added to calculate the dead load of the roof. TABLE OF CONTENTS 2 3. CONSTRUCTION MARKET UPDATE General Overview 77 Construction Sector 79 4. FINANCIAL Philippines Key Data 89 Economic Highlights 90 To calculate the density of the plasterboard, establish the weight per square metre and divide it by its thickness (metres), e.g. 12.5mm Gyproc WallBoard weighs 8kg/m2, divide by 0.0125m = 640kg/m3. Accordingly, how much does a 8x4 sheet of drywall weight? While the weight of drywall at 5/8” thickness is about 2.31 pounds per square foot. hs3Pu.
