Rotting SIP roofs in Juneau Part I: The Base Line Info

by Steve Andrews

SIP Manufacturers Respond

Mike Bryan, Premier Building Systems
"What I know is there were a number of Premier panels, back when we were
an
R-Control plant, that were installed in Juneau, and now we have problems
with the top layer of OSB turning to mush," said Premier's Mike Bryan.

"Last February through May, we sent three different people up on four
different occasions. During our investigations, we determined that there
were numerous problems with the installations. The builder's liability
insurance company paid the entire bill. The problems with the
installations
were so flagrant that they didn't have much choice. The good news is that
80%-90% of the people want replacement panels on their new roofs."

Fine. It does, however, illustrate
that there can be installation
problems,

That is the case with any construction method.

and I already mentioned the
potential for infestations.

Which is not a point in the UK, and will no longer be a point in the US.

Neither is intended to say that
this technology may not have some use,
but it is certainly not without its share of issues.

What isues are those?

When compiling a list of advantage and disadvantages the disadvantages are
few and far between.

In terms of the end result and the implications of putting it right,
it doesn't matter whether it is the material or the way it is
installed. However, it is clearly not as idiot proof as the
manufacturers would like to claim.

It is idiot proof if you follow the instructions. If you don't follow the
instruction with IKEA furniture it wobbles.

In any event, a manufacturer is hardly
likely to say that problems are
inherent in his product, is he?

An official report put it squarly with shoddy workmanship.
