Crosstech®
The Crosstech® (Type 2C), from W.L. Gore, is both the most breathable
and durable moisture barrier product available today. The enhanced PTFEbased bicomponent
membrane technology incorporated within the Crosstech® moisture barrier improves
upon the already superior performance capabilities of Gore’s “original” Crosstech®
moisture barrier. Among the improvements, the primary benefits to the user are increased
total heat loss and an overall greater durability – both of which are still provided
in conjunction with the already superior thermal stability performance of Gore’s
expanded PTFE Teflon based products. It is Morning Pride by Honeywell’s position that the Crosstech®
moisture barrier is the preeminent moisture barrier available today. While we do
not recommend any particular outer shell or liner material as the best choice for
all customers, we DO recommend the improved Crosstech® barrier as the moisture barrier
of choice (it offers such significant and field proven advantages) to ALL our customers.
While slightly more expensive than alternative moisture barriers, the Crosstech®
barrier product offers compellingly better properties and, with its comparatively
better durability, is almost assuredly a lower life cycle cost product than products
of lower initial cost (but with less durability).
RT7100®
This alternative PTFE-based moisture barrier is a product of W.L. Gore. It incorporates
Gore PTFE technology, however, NOT the enhanced bicomponent technology that is part
of the new and improved Crosstech® moisture barrier, nor the technology that was
used in the “original” Crosstech® barriers. This alternative product is intended
as a thermally stable, price competitive alternative to NFPA compliant polyurethane
based moisture barriers without the superior product benefit advantages of the Crosstech®
moisture barrier. While the Crosstech® moisture barrier, discussed above, continues
to be the market’s premier moisture barrier for excellent performance, not all departments
are able to justify the slightly higher investment. The Gore RT7100® moisture barrier
was specifically designed to meet the demands and cost considerations of many in
the fire service. Its thermal stability and non-cracking, non-flaking performance
is unmatched in its price range.
