Dura-Film® Winterguard

4-mil performance in a 3-mil overwintering film.
AT Films has developed the most advanced polymer blend available for our Dura-Film Winterguard products. These films are truly a new generation of overwintering protection. Since AT Films introduced this super strength overwintering film in 1997 thousands of growers, all over North America, have successfully switched from traditional 4-mil overwintering products to our 3-mil Dura-Film Winterguard film. This new 3-mil film has much better tear strength, stronger folds and takes greater energy to puncture than the 4-mil 'co-poly' that are currently available! Dura-Film Winterguard is also 25% lighter than standard 4-mil co-poly -- that's 25% less weight during installation and 25% less film to dispose of next spring.
When an even tougher film is required, Dura-Film Winterguard is also available in super strong 5-mil gauge.
Dura-Film Winterguard is available in a wide selection of stock sizes.
The following minimums apply for custom Dura-Film Winterguard products:
- For widths of 20' or less, a minimum of 2,000 lbs per order, per width, per gauge and per opacity is required
- For widths greater than 20', a minimum of 5,000 lbs per order, per width, per gauge and per opacity is required
