How to install snow fence
Principle of controlling a snow drift:
First and foremost, a snow fence is designed to CREATE snow drifts, not prevent them. Snow fences ultimately perform as windbreaks, causing the snow to be deposited as snow drifts when the wind slows down.
Basics of drift control are:
- Keep the wind blowing or moving.
- Slow the windspeed down with snow fence where snow drifts are wanted.
- The higher the snow fence is off the ground (still less than 2 ft.), the further away the drift will start. If the snow fence is placed on the ground, the snow fence will be buried with the snow drift.
- Proper installation is critical to success.
Previous Page Suggested Installation Instruction for Snow Fence:
- Snow fence should be positioned upwind of the desired drift area, noting the prevailing wind direction.
- Bury the fence posts 1/3 of their height, place the T-posts no more than 8' apart. (Note: Metal U-posts or rebar are not recommended as supports for snow fences.) Please note that when tensile strength is the biggest concern typically the posts are the weakest link in successfully controlling the snow drift.
- Pull the snow fence taught and secure to the posts with plastic fence ties (zip ties) with a minimum 5" gap at the bottom of the fenceto prevent burying. In addition, the snow fence should be attached on the upwind side of the post to prevent tearing. Loop the ties through the available holes or "teeth" in the post to prevent the snow fence from sliding down the post. Support wires should stabalize end post to prevent sagging.
- For additional longevity, pull the snow fence taught and secure between the flat side of the T-post and the wood slat. Or weave the slat through the fence mesh and use it as a tension bar to pull the fence snug. Then secure the slat to the post. Use plastic fence ties (zip ties) to secure the slat and snow fence to the T-post at the top, middle and bottom of the fence. Loop the tie through the "tooth" at the top and the bottom of the T-post to prevent the fence from sliding down the post.
- For the greatest longevity of the snow fence it can be suspended from a wire (plastic, metal, rope etc.), this is in addition to the securing method described in #2 and #3. The wire should be weaved through the upper openings of the snow fence and through the holes in the posts; the wire shall then be secured at both ends of the snow fence.
- To connect snow fence sections, overlap both ends by at least 6" and weave a wood slat through overlapping strands. Secure the joined area to a post.
Please note that if an engineer has specified snow fence installation for specific applications; those would supercede the above recommendations, assuming more strict requirements.
