| Brattice Cloth Selection |
One of the most important physical characteristics of nearly
any brattice cloth application concerns its tear strength. Both
weight and tear strength can be altered by varying the raw material
components (scrim or substrate, adhesive and film layers). Heavier
does not necessarily mean stronger. The actual scrim utilized
will normally have the most impact on the ultimate tear strength
of each fabric.
An inexpensive brattice cloth selection does not make the choice
necessarily cost-effective. Let a Sales Engineer answer your
ventilation questions and provide assistance in making the proper
product selection to meet your specific requirements. |

 VentaTex®
and VentaLene™Knitted Scrim |
 |
Conventional - Weft-Insertion Knitted Scrim
VentaTex® and VentaLene™ (VL) fabrics incorporate
a base of synthetic scrim between two sheets of virgin vinyl.
Overstitching a non-woven web produces the scrim, it is then
introduced to the vinyl. These layers are subsequently laminated
together using adhesives, coupled with various temperature and
pressure changes. The result is a strong, tough, low-maintenance,
waterproof and fire resistant fabric. These fabrics are excellent
choices for Brattice Cloth and Flexible Tubing applications. |

RipStop - Weft-Insertion Knitted Scrim
VentaTex® and VentaLene™fabrics with the RipStop feature
are manufactured similarly to the conventional style. However,
RipStop refers to a fabric with heavier yarns laid in regular
intervals in both the warp and fill directions. The benefit
of this heavier yarn is it can block a small tear from developing
into a major tear. As the tear moves through the fabric, it
pushes the yarn behind it. These yarns continue to stack up
against one another, each adding its strength to the pile.
This is called bundling and it creates enough resistance to
stop the tear from progressing further.
VentaTex®RipStop is manufactured under U.S. Patent
#4,615,934 and Canada Patent #1,254,758.
