Mass Loaded Vinyl

Installaon Guide

Mass Loaded Vinyl (MLV) is

a heavy, vinyl sheeng material

that is used to reduce sound

transmission and unwanted noise. The

weight and mass of MLV are achieved with

a proprietary formulaon giving MLV its heavy

density while retaining exibility. Mass Loaded

Vinyl is considered to be one of the most eecve

sound-blocking materials available.

Mass Loaded Vinyl is a safe, non-toxic, odorless barrier designed

to achieve maximum sound isolaon in a variety of soundproong

applicaons such as:

Instrucons

The installaon of Mass Loaded Vinyl is

very straighorward. However, there

are some recommendaons for opmal

performance. For best results when

installing in walls, it is recommended that

MLV be placed against the studs, under

the drywall installaon. Although not

necessary, it is suggested that MLV be

hung vercally. This method allows for the

easy taping of secons. Alternavely, MLV

can be placed over the exisng drywall.

Required Tools & Supplies • • • • • • • • • • Step 1 — Measure Wall Measure the distance between the ceiling or top plate and the floor. Subtract 1/8” - 1/4” from the measured length. Mass Loaded Vinyl Tape Measure Utility Knife T-Square or Straight Edge Drill or Impact Driver Drywall Screws & Washers or Cap Nails Seam Tape Acoustical Sealant Caulk Gun Installation Steps Step 2a — Measure & Cut MLV Roll out the Mass Loaded Vinyl and measure out the length you need to cut for the section you’re applying.

Step 2c: Hold the T-Square firmly in place as you make your cut to ensure a clean, straight edge on the MLV section. Step 3 — Hanging MLV Installation Steps With the help of another person, position the first length of MLV in the top corner of the wall. Ensure that the section of MLV is straight and that the cut edge is parallel to the ceiling. This will help ensure the seams of additional sections remain parallel.

Step 5 — Cutting Outlets Be sure not to cover electrical outlet boxes. It’s helpful to expose the outlet boxes as you install each length of MLV. Locate the electrical box in the wall and gently press the MLV against the box. Using a utility knife, carefully cut the opening tightly to the edges of the junction box. For an even better sound seal consider using a putty pad to seal the rear side of the junction box.

Dealing with seams and overlaps - continued from page 4 top plate Figure 1: When the sections of MLV meet together on a stud do not overlap. Butt the seams tightly together and fasten with screws and washers or Figure 1 capped nails in an alternating pattern every 8”-10” butt seam along the stud as pictured.

Step 8 — Caulking Hang drywall over the Mass Loaded Vinyl, vertically or horizontally. Caulk all seams along with all floor and ceiling gaps with Acoustical Sealant and a caulk gun. Installation Steps Anywhere there are air gaps, sound waves will easily pass through. Proper seam sealing is necessary to achieve the highest level of noise reduction. Step 9 — Mudding Finally, mud all drywall seams and finish the wall or ceiling as desired to achieve the finished look.
