Installaon Steps
Step 7 — Taping
Using MLV seam tape, seal all seams where the MLV
bus together and on overlapping seams. This will
further reduce the transmission of unwanted noise
by eliminang air gaps between secons of the MLV
material.

Dealing with seams and overlaps
- connued from page 4
Figure 1: When the secons of MLV meet together
on a stud do not overlap. Bu the seams ghtly
together and fasten with screws and washers or
capped nails in an alternang paern every 8”-10”
along the stud as pictured.
Figure 2: When the secons of MLV don’t
meet together on a stud, overlap the secons
approximately 2” and fasten each secon along the
closest adjacent stud with screws and washers or
capped nails as pictured. Fasten the overlapping
seam together with MLV seam tape.
Figure 3: Where secons of MLV overlap it is
important to notch them at the top and boom
plate so that they lay at for drywall installaon.
Start by cung through both layers of overlapped
MLV parallel to the top and boom plates. Then cut
through both layers of MLV, where they cross the
top and boom plates, perpendicular to the oor
and ceiling. This will create an L-shaped notch when
you remove the cut-out material from the top-most
overlapping layer of MLV. Finally, secure the newly
created bu joints, where they cross the wall plates
in the L-shaped notch, with screws and washers or
capped nails as pictured. Finish the notch by taping
over all seams with MLV seam tap.
