The Family Handyman recommends a clever way of determining the size of fence you need to ensure privacy. With this in mind, you can seek advice from a professional tradesperson about materials and design for a fence capable of withstanding high wind. This is likely to consist of more -- and longer -- fence posts with narrower panels.
Ask a friend to walk around your garden perimeter with a large piece of cardboard. Get your friend to hold up the card at various heights until you have determined the best height to ensure privacy. Measure the height of the card. This is the height of fence you need to build.
Use an anemometer to determine the wind speed in your garden on a typically windy day. As of May 2013, you can purchase one for about £15. Alternatively, use The Energy Saving Trust’s wind speed prediction tool for an approximate wind speed reading for your area.
Ask your fencing supplies merchant for advice on making your fence strong enough to cope with the wind level in your area. Explain that the fence needs to be at the height previously determined to ensure privacy. Purchase materials on the basis of advice from your fencing supplies merchant.
Mark the positions for posts on the perimeter with marking spray. The spacing will be determined by the width of the panels. Dig out the post holes. Place 10 to 20 cm of hardcore in the bottom of each hole. This will provide a key for the concrete and allow groundwater to drain away from the posts, thus helping to prevent rot.
Place the first post in the first hole. Ask your friend to support the post while holding a spirit level against it to ensure it is vertical. Fill the hole up to ground level with concrete. Proceed in like manner for all the fence posts. Allow the concrete to “go off” or cure. According to The Concrete Society, this could take up to three days.
Fix the fencing panels between the posts with galvanised fence fixing clips. Use the spirit level to ensure consistent height. Place clips around the edges of the panels and attach them to the posts with galvanised clout nails.
Buy pressure treated fence materials as they offer better protection against the rain. A desire for both privacy and a fence capable of withstanding high wind is slightly contradictory. Hurricane fencing -- also known as chain-link -- often withstands wind better as it blows through the gaps.
