Lumber and materials information
The playhouse walls and roof are covered with a 240mm wide x 7.5mm
thick (9 1/4" wide x 5/16" thick) cement fibreboard. Cement fibreboard
lap siding is now very obtainable and its popularity is growing fast.
It is easy to work with, very strong, resistant to fires, insects and
rot, and looks good.
One company that manufactures cement fibreboards in many countries
worldwide including North America, Europe, Australasia and Asia, is
James Hardie. Go to their website http://www.jameshardie.com to find a
stockist near you. There are also other companies that manufacture a
similar product or alternatively, you can use lumber boards (clap
board) in place of cement fibreboard.
Lumber sizes
The dimensions of the lumber used for this project are given in both
metric and inches. All dimensions are first written in millimeters,
followed by feet and/or inches in brackets.
The lumber used in this project is dressed (surfaced, smooth) lumber.
Therefore the actual size (width and thickness) of the lumber is less
than the nominal size. The nominal size is usually the size that you
refer to when purchasing the lumber, but the actual size is different.
