Obtain an R-WALL estimate

To calculate the Gross Square Meterage (Sqm) of the walls work out the length of the walls you wish to be constructed in R-Wall and multiply this by their respective heights. You may need to work this out in sections or over floor levels. If you have gables obtain the length and maximum height of this element and divide this figure by 2. Add all calculated areas together. For a visual demonstration click the diagram

To work out the total Square meterage of the openings take the window heights and multiply that by the window widths. Eg a standard window is 1.2 high x 1.2 wide = 1.44 sqm. Do this for all windows and door openings and add them together to obtain a total. Please click the diagram for a visual demonstration.

To work out the perimeter of the build measure the external meterage of the footprint. Click the image for a visual demonstration

To work out the square meterage of the floor area you must calculate length x width as per illustration;
