Weather
proofing is also a main concern when it comes to door
design. Our system has been tested at a UKAS accredited
testing station and passed the PAS23 weather test to extreme
weather conditions of over 300 pascals. Most systems on the
market are weather tight, with high performance rubber seals
and brush seals. However, there are some systems that have
little or no seals at all. One crude but easy test is to
close a folding door onto a sheet of paper and try to pull
the paper out. If it pulls out easily there is not a water
tight compression on the seals.
We
use 2 rubber EPDM seals on each side of each panel and high
performance seals on the top and bottom of the panel.
The
system also includes a tongue and groove feature to (1)
prevent water infiltration, (2)keep the system stable with
one panel interlocking with another and (3) to preventattack
by an intruder.
