Erosion Blanket - Single Net - WinterStraw

WinterStraw™ Single Net Products are short term, single top net erosion control blankets that are machineassembled
using 100% agricultural straw fibers. The straw fibers are evenly distributed throughout the entire area
of the blanket to a rough thickness of 3/8” and stitched to your choice of netting using high strength degradable
thread. Biodegradable thread is used on our Bio (Jute) products.
Each blanket is covered on the top with a single photodegradable polypropylene or jute. Net openings are
approximately ½” wide x ½” long and are stitched on 1 ½” centers for increased performance capabilities.

Netting options: Functional Longevity
Green Net – Standard photodegradable polypropylene netting. 12 Months
White Net – Rapidly degrading, polypropylene netting w/ UV degrader additive. 3 Months
Jute Net – Biodegradable jute fiber netting. 12 Months
All WinterStraw™ blankets are individually labeled and shrink-wrapped to protect against the weather and damage.

Performance Characteristics:
WinterStraw™ blankets are designed to provide temporary ground cover to reduce erosion, protect seeding, enhance
germination, and speed re-vegetation. Functional longevity is between 3 and 12 months depending on soil conditions,
climate, geography, and choice of netting. Testing shows SNG, SNW, and Bio blankets are suitable for the following

Slopes: up to 3:1

Channel flows: up to 3.5 ft per second

Shear Stress: up to 1.25 lbs/ft².

All figures are based on product at the time it is manufactured.

WinterStraw™ blankets are constructed of 100% Natural Straw fibers stitched to a single photodegradable
polypropylene net using degradable thread. WinterStraw™ Bio blankets offer biodegradable Jute netting and
high tensile biodegradable thread. Our blankets are designed to protect against erosion by providing temporary
ground cover while enhancing seed germination and assisting with vegetation establishment.
Functional longevity is as short as 45 days and up to 12 months depending on product used and site conditions.
Soil erosion is controlled by the root system, stem and leaf structure of the mature vegetation after the blankets
WinterStraw Single Net blankets are rated for channel flows up to 3.5 feet per second and 1.25 lbs/ft² shear stress.
Additionally, our blankets have a design C-Factor of .046 and are typically appropriate for up to 3:1 slopes.
