Baltic pine was used extensively in Melbourne house construction up until the 1950s. As a general rule of thumb the boards are either 150 mm or 100 mm wide, however there are various other uncommon sizes. The thickness of the boards depends on the era the home was built. Post World War Two homes generally have 19 mm thick boards. From the beginning of the 20th century to the end of WW2 the thicknes is normally 22 mm and prior to this time the thickness could be 22 mm, 28 mm or even 32 mm.
There are four common sizes of baltic pine found in Melbourne
150 mm x 22 mm ($18 per lineal metre)
150 mm x 19 mm ($14 per lineal metre)
100 mm x 22 mm ($9 per lineal metre)
100 mm x 19 mm ($7 per lineal metre)
Melbourne Recycled Timber Floorboards normally stock all these sizes, however supply does tend to fluctuate due to supply and demand. There is no doubt the amount of baltic pine on the market has diminished in recent years as the demolition of pre WW2 homes decreased.
