ASBESTOS ENCAPSULATION
What makes an Asbestos roof.
Asbestos roofing is a matrix of Portland cement and
White Asbestos, the average content of White Asbestos is
10%, of the three types of Asbestos White, Brown and
Blue, White is considered the least dangerous, this is
due to the length of the fibres which need to be of a
certain length to form the matrix.
Asbestos as a roofing system
Asbestos is a very good material for use as a roofing
system as the material is fire proof and very long
lasting, in some cases well over 60 years. It is
susceptible to the freeze thaw cycle and the growth of
lichen, this is why an Asbestos roof will remain in
better condition along the coast as apposed to one in a
mountainous region, but an Asbestos roof can be
rejuvenated with WDG System 14 quicker and for far less
cost than replacement. As WDG System 14 is not affected
by the freeze thaw cycle and the growth of lichen, it is
also fire rated and very long lasting, making it the
ideal solution for anyone with the need to replace or
insulate an Asbestos roof.
Replacing an Asbestos roof
This involves a long and very expensive process, you
must engage a licensed contractor to comply with Health
and Safety regulations, the facility must be closed down
and sealed off, the Asbestos is then removed and shipped
off to be incinerated, this process can cost more than
the replacement roofing system which then has to be
installed, if this is to be an insulating system the
cost will rise even further. WDG System 14 is an
insulating system which can be applied in a fraction of
the time, with no down time for a facility and cost far
less than replacement, and because there is no direct
contact with the Asbestos during application, it
complies with the Health and Safety regulations.
What is Asbestos encapsulation
Some companies claim to insulate and encapsulate
Asbestos from the inside, the problem with this process
is, it requires the facility to close down during
application, it will not protect the Asbestos from the
elements, the Asbestos will continue to break down, the
freeze thaw cycle and lichen growth will speed up year
on year until the Asbestos breaks down completely,
plastic and rubber washers used on the metal fasteners
also break down due to UV radiation, then the roof will
have to be replaced.
Because WDG System 14 is applied to the outside there is
no need for a facility to close down during application,
business can continue as normal, after installation the
Asbestos is protected from the elements including the
plastic and rubber washers, thermal bridging is
eliminated and the roof is completely sealed with an
unlimited wind uplift guarantee. WDG System 14 is a long
lasting solution, while most roofing systems have
warranties between 10-20 years, WDG System 14 can be
guaranteed for up to 30 years, the insulation is
guaranteed indefinitely and unlike other systems, at the
end of the warranty period you simply re-coat the roof
with Silicone from WDG and the original warranty is
reinstated.
The benefits of encapsulation
WDG System 14 used for encapsulation is a huge benefit
to the building owner, it is quicker, cheaper and less
obtrusive than any other system, it is also fire rated
and very long lasting with a proven history of
performance, with warranties up to 30 years, it turns
your roof into an investment not a cost.
