4x2 Planed Timber External Door 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; 4x2 Planed Softwood External Casing can not be recommended for use externally without suitable timber treatment & weather-proof coating; External use of Moulded Redwood External 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.
