Silva Select Prestige VG is the ultimate in wood cladding. What makes it so special is the fact that it is produced exclusively from old growth vertical grain Western Red Cedar. Also known as ‘quarter sawn’, vertical grain boards are cut so that the growth rings are vertical (or at an angle greater than 45°) to the face of the board.
Normally Western Red Cedar cladding is mixed grain, meaning that some boards will be vertical grain and others will be flat grain. Now Silva has gone the extra mile to source raw material that is 100% vertical grain. Simply put, it’s the best of the best – the ultimate in appearance and performance.
For centuries builders have recognised that vertical grain timber has superior properties to flat grain, particularly when it is being used in severe exposures. In New England for example, there are many examples of homes, barns and churches built from vertical grain Western Red Cedar that are over 100 years old and still going strong.
With flat grain wood, the growth rings run roughly parallel with the face of the board, so when they shrink, boards have more of a tendency to cup. Vertical grain boards tend to shrink across the thickness so they remain flat with virtually no movement, meaning very low surface cracking and checking.
Wood scientists have proved that vertical grain wood has better finish absorption and retention qualities than flat grain wood. This means that finishes last longer so won’t need re-applying as frequently, and thus maintenance costs will be reduced. Also, the absorption rate - and therefore the appearance and performance - of the finish will be more consistent, since it is only going into vertical grain wood. As a result, a project will look good for longer.
