The reclaimed wood we sell has many layers beyond the resource itself. We break our lumber down into 3 classifications based on properties and sizing. Lumber through time changed from old growth fir to second/third growth fir to the SPF of today. In general, reclaimed wood has the lightest footprint of all building materials and using it has a huge positive environmental impact.
R4S (Pre-1920s )
-
Old Growth fir
-
R4S – Rough sawn on 4 sides
-
True dimensional – a 2×4 is 2”x4” (sizes vary due to the historical milling)
R2S (1920-1945)
-
Old Growth Fir
-
R2S – Rough sawn on 2 sides (though can be smooth occasionally)
-
Large dimensional (a 2×4 is 1 3/4”x3 3/4”)
S4S (1945-1980s)
-
Typically Old Growth fir into the 1970s
-
S4S – smooth on 4 sides (Vancouver Island wood has rough sawn into the 1970s)
-
Modern dimensions (a 2×4 is 1 1/2” x 3 1/2”)
