Snow fences are used to redirect snow away from roads, driveways, and walkways. They are designed to slow down the wind, causing a drift to pile up on the downwind side of the fence, instead of in areas that need to be kept clear. Snow fences are usually made of plastic or wood, with holes or slats covering much of their surface. The ideal snow fence is 40 to 50% porous, meaning these openings cover about half the surface area. When installing a snow fence, it is important to consider the direction of the prevailing winds in your area, as well as the length and height of the fence, and the distance between the fence and the area you want to protect.

What You'll Learn
Planning and research
Research the direction of the prevailing winter winds in your area. This information can be found in meteorological data from weather stations, by examining drift features in aerial photographs, and by checking the orientation of vegetation, such as bent trees. The fence should be placed upwind of the area it is protecting, roughly perpendicular to the wind direction. For example, if the wind blows from east to west, you will need a snow fence on the east side of the area, running north-south.
Calculate the distance between the fence and the protected area. A snow fence slows the wind enough to deposit the snow in a drift downwind of the fence, so the fence must be far enough away from the protected area to prevent making the problem worse. As a general rule, a snow fence will cause a drift up to a distance of 20 times the height of the fence, so this is the minimum distance you want between the fence and the protected object. If you need to keep the area completely clear of snow, install the fence at a distance of 35 times the height of the fence.
Check the fence porosity. The ideal snow fence is 40 to 50% porous, meaning these openings cover about half the surface area. A fence with a much lower or greater porosity will be much less effective. Each hole or slat is usually 2 to 2.5 inches (5–6 cm) wide. Openings wider than 6 inches (15 cm) are not effective.
Determine the length of the fence. To ensure maximum protection, multiply the height of the fence by 20 to extend the length of the fence in both directions. This compensates for the fact that the ends of the fence are less effective at blocking snow. For example, if you are building an 8-foot (2.4m) fence, extend it by 200 feet (61m) past the protected area in both directions.
It is important to note that the exact size and placement of your fence depend on local weather conditions. A thorough knowledge of the problem is needed to estimate a sound solution.

Choosing the right materials
Fence Material
Plastic snow fences are a popular choice due to their lightweight, economical, and easy-to-install nature. Look for fencing made from high-density polyethylene, as it is durable, flexible, and won't become fragile in cold weather. This material is also UV-stabilized, ensuring it remains stable under prolonged sun exposure. Additionally, seek out fencing with 40-50% porosity, as this level of openness allows for effective snow control while maintaining structural integrity.
Posts
While plastic fencing can be attached to various types of posts, steel T-posts are recommended for their strength and durability. These posts provide robust support and can withstand high winds when properly installed. If you prefer a more natural look or are concerned about cost, wooden posts are also an option, though they may require more maintenance over time. For optimal stability, plan to space your posts no more than 6 to 8 feet apart, and insert them at least 1.5 feet into the ground.
Fasteners
To secure the plastic fencing to the posts, use cable ties or recycled plastic baling twine. Cable ties provide a strong and secure connection, especially when combined with wood slats. If you opt for twine, wrap it in a barber pole fashion for a secure connection. Additionally, consider using plastic cable for additional security; lace it through the apertures at the top and bottom edges of the fence.
Post Driver
A post driver is an essential tool for installing your snow fence. It helps you securely insert the posts into the ground, ensuring they are firmly anchored and able to withstand wind and snow loads.
By carefully selecting these materials and following installation guidelines, you can construct a plastic snow fence that effectively redirects snowdrift and protects your property from harsh winter conditions.

Installing the fence posts
Installing fence posts for a plastic snow fence requires careful planning and consideration of the local weather conditions. Here is a step-by-step guide to installing the fence posts:
Step 1: Research and Planning
Before installing the fence posts, it is crucial to understand the prevailing wind direction in your area. Meteorological data from weather stations, aerial photographs, and vegetation patterns can help determine the wind direction. The fence should be positioned perpendicular to the wind direction, with the fence posts placed upwind to prevent tearing. Additionally, calculate the distance between the fence and the area you want to protect, ensuring it is sufficient to allow snow drifts to form at a safe distance.
Step 2: Determining Fence Length and Placement
The length of your plastic snow fence will depend on the height of the fence and the extent of the protected area. For maximum protection, multiply the fence height by 20 to determine the additional length needed on each side. Consider the terrain and any obstacles that may affect wind flow, and adjust the fence placement accordingly. The fence posts should be spaced no more than 8 feet apart, with end posts placed 6 feet or less from the adjacent posts to facilitate bracing.
Step 3: Installing the Posts
Use a post driver to insert T-posts securely into the ground. For added strength, consider using steel T-posts with wood slats. Place the posts in a zigzag pattern, ensuring they are inserted at least 1.5 feet into the ground and no more than 8 feet apart. The height of the posts will depend on the desired height of your plastic snow fence, typically starting at a minimum of 5 feet above the ground.
Step 4: Attaching the Fencing
Attach the plastic fencing to the upwind side of the posts, sandwiching it between the flat side of the T-post and a wood slat using cable ties. Pull the fencing taut and secure it with ties placed every 1 foot on metal posts or with nails or staples on wood posts. For added security, lace plastic cable through the apertures on the top and bottom edges of the fence.

Attaching the plastic fencing
For additional security, you can use plastic cable, lacing the cable through the apertures in the top and bottom edges of the fence. To connect fence sections, overlap the two adjoining ends by at least 6 feet and weave through the overlapping ends, securing with ties. Pull the fence taut and fasten the net to the support structure with plastic ties placed every 1 foot on metal posts. For wooden posts, use nails or metal staples.
It is important to note that the fence should be placed perpendicular to the wind direction for optimum drift control. The fence should be positioned upwind of the area it is protecting, roughly perpendicular to the wind. For example, if the wind blows from east to west, the fence should be placed on the east side of the area, running north-south.

Maintenance and upkeep
Plastic snow fences are low-maintenance compared to their wooden counterparts. They are resistant to moisture and weather-related elements, such as sleet and hail, and do not require treatment with stain or paint. When cared for properly, a plastic snow fence can last for several years.
However, to ensure optimal performance, it is essential to conduct periodic maintenance checks. These checks should include inspecting the anchoring system and looking for any missing or damaged parts. The fence posts should be strong, firmly anchored, and spaced no more than 8 feet apart for 4 ft. snow fences. End posts should be placed 6 ft. or less from the adjacent post to facilitate bracing.
Additionally, pay attention to the fence's porosity, which refers to the open area of the fence. A porosity of 40-50% is recommended to ensure the fence functions effectively. Each hole or slat should be 2 to 2.5 inches (5–6 cm) wide, and openings wider than 6 inches (15 cm) are considered ineffective.
When not in use, plastic snow fences should be properly removed and stored for the season. Unlike wooden fences, plastic snow fences cannot be easily repaired if they break and will likely need to be replaced.
