GT Films offer traditional overwinter poly and as well as a new generation of overwintering protection with 1 year UV life.

 

1 year UV Life

Available in 3 or 5 mil thickness, clear or white, our 1 year film offers superior UV resistance of all Nursery films

3 mil Overwinter

This super strength overwintering film has improved tear strength, stronger folds and takes greater force to puncture than the 4-mil 'co-poly' that is traditionally used.  It 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, this film is also available in super strong 5-mil gauge.

 

    Overwinter films are available in a wide selection of stock sizes.
    The following minimums apply for custom Overwinter 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
