- Calculate the surface area for your decking Multiply the length (L) of your decking area by the width (W): L x W = Decking Surface Area (DSA) in m2 10 x 6 = 60m2
- Work out the coverage of your deck boards Add your deck board width (DBW) to the expansion gap length (EGL), then add the deck board length (DBL) to the expansion gap width (EGW). Then multiply these numbers. (DBW + EGL) x (DBL + EGW) = Single Board Coverage (SBC) 0.144m + 0.005m = 0.149m 2.4m + 0.003m = 2.403m 0.149 x 2.403 = 0.358m2
- Calculate the number of deck boards you need Multiply the SBC by 1.1 to allow for 10% wastage. Then, divide the DSA by the SBC. DSA / SCB x 1.1 = Total number of boards required 60m2 / 0.358m2 x 1.1 = 184.36 boards – so round up to 185 so you’re not left short.
Canonbie
Canonbie (population 390) is a little village in Dumfriesshire within the local authority location of Dumfries as well as Galloway in Scotland, six miles south of Langholm and two miles north of the Anglo-Scottish border. It is on the A7 road from Carlisle to Edinburgh, as well as the River Esk flows with it. There are frequent referrals in older files to it as Canobie. Canonbie was immortalised in a poem by Sir Walter Scott entitled Marmion. A renowned section covers the exploits of young Lochinvar. Having swiped the hand of the new bride of Netherby Hall, about 3 miles south of Canonbie, the rushing knight is chased with Canonbie, yet makes good his escape.
