4x1.5" Planed Timber Internal Casing should be treated and fixed in place as soon as possible to help minimise any movement/­twisting and surface checking/­splitting that occurs naturally with changes in moisture content; 4" Softwood Internal Door Casings are not recommended for external use; External use of Moulded Redwood Door Casing is at your own risk - Timber life expectancy is increased with good timber treatment and protective finishing coats. It is better to use pressure treated timbers externally.
