Quiet Walk Flooring Underlayment
 Quiet
Walk® underlayment is the "hallmark" product, produced by
Midwest Padding, a leading american producer of flooring underlays.
It's Quiet Walk, flooring underlayment not only smoothes
out small sub floor imperfections, but also quiets impact
sound and floor to ceiling noise transmission. It reduces
sound that would typically migrate into the room below.
In laboratory tests it has been shown to have noise
reduction characteristics consistent with traditional
acoustical rubber underlay and cork, but at a significantly
better price point.
Typical Price: .32-.45$/sq.ft
As a side benifits the fiber content provides an "R"
value of .5, offering a warmer installation particularly on
below grade applications.
They have incorporate an EPA registered anti-microbial compound
in QuietWalk® to control mold or bacteria on the treated product
and a vapour barrier for a 2 in 1 application... although
its downside is that it is necessary to fully tape the seams
to create a continuous vapour imperious barrier.
The competing Solid Walk LT - 2 in 1 underlay (Solid Sound
Flooring-Pak Lite Inc) is nice, because for a few extra pennies
it has an overlapping polyethylene film with a peal and stick
seam to elimate the cost and labour of secondary taping.
Midwest Padding does produce a number of more economical
padding, but with much less sound reduction capabilities.
Its traditional foam underlayment is called Polyfoam, and
is much in line both in price and characteristic to most others
on the market.
 DuoFoam
is its 2 in 1 line that has a laminated Polyfoam & Polyethethylene
film to provide both cushioning and a built in vapour barrier
in one product. Like the Solid Walk, it is nice because it
has an overextending band of plastic film to allow vapour
barrier lapping and a peel and stick strip to hold it in place.
