Appearance
British larch ranges in colour from pinky-brown in the heartwood, to creamy-white in the sap band. Depending on the grade, there will be some or many dark brown knots and occasional resin pockets along the length of the board.
Weathering
British larch weathers relatively slowly, often taking two years to reach a silver-grey patina. Larch is quite consistent and is not reactive, and as such, will weather relatively evenly. Northerly elevations may weather to a darker grey than those facing South.
Desired service life
Occasionally wet 30 yrs. Frequently wet 15 yrs.
Movement class
Large
Resistance to impact
High
Working properties
Good workability. Takes fixings satisfactorily although can be prone to splitting.
Density
570 – 650 Kg / m3
Extractives
British larch contains resin rather than oil or tannin.
How to fix
Pre-drill and hand nail with stainless steel nails through the face. Do not attempt to secret nail through the tongue. We do not recommend first or second fix nail guns with larch, because it can be an unstable timber.
** Be sure to leave an expansion gap between machined boards**
