Here's a little tip that I would like to relate. If and when you
settle on a system (e.g., Nederman), be sure to specify the name and
model in all the appropriate project documents. *Do not* let the
architect include a clause that says, "or equivalent." The
contractor may use this as a license to install a cheap substitute
cobbled together from off-the-shelf parts. The result will not come
close to a commercially available model in terms of performance or
design. You could end up with an installation that sounds like a
central vac, is embarrassingly crude to look at, and cannot be made
useable with any amount of retrofitting (e.g.,  fiberglass
insulation "soundproofing"). Insist on a brand name and don't budge
an inch. At least then you'll have some recourse if it doesn't meet
your expectations.
