TotalMass and ArrowZoom both sell mass loaded vinyl, but they package it for very different jobs. TotalMass is available in wide construction rolls with several surface-weight options. ArrowZoom’s current range focuses on a compact cut-to-fit sheet and pre-cut tiles marketed at 2 lb per square foot.
That difference matters more than the brand name. A large roll can cover framing bays or a broad wall with fewer seams, but it is heavy and awkward to lift. Smaller sheets are easier to carry, cut and position around irregular shapes, but covering a whole room with them creates more joints and usually costs more per square foot.
This comparison uses the manufacturers’ current specifications rather than the older ArrowZoom fabric product that is still described on some pages. It also separates standalone material ratings from installed wall performance. MLV can improve airborne-noise control when it is installed as a continuous barrier, but neither product is a magic fix for every sound problem.
Quick Verdict: TotalMass or ArrowZoom?
TotalMass is the better fit for large walls, ceilings, mechanical areas and construction projects. Its 4-foot-wide rolls provide 40 to 100 square feet of coverage, depending on the selected weight and roll size. It also gives you 1/2 lb, 1 lb and 2 lb choices instead of forcing every job into one density.
ArrowZoom is the more manageable option for a small section, door, enclosure, vehicle panel or irregular shape. Its 1-square-meter cut-to-fit sheet weighs about 22 pounds, while its 12-by-12-inch tiles let you buy and place smaller pieces. That convenience comes with more seams if you try to cover a large surface.
| Choose | Best reason to choose it | Main tradeoff |
|---|---|---|
| TotalMass | Wide coverage, fewer seams and three surface-weight options | Full rolls can weigh 42 to 122 pounds |
| ArrowZoom | Compact sheet or tiles for smaller and irregular areas | More joints and limited coverage per piece |
The short version is that TotalMass wins on large-project practicality, while ArrowZoom wins on small-piece handling. Sound performance still depends on the exact variant, the surrounding assembly and how completely you seal the barrier.

TotalMass sizes and weights
TotalMass offers more ways to match the barrier to the job. Its 1/2 lb material is listed as 1/16 inch thick in a 4-by-25-foot roll that weighs about 52 pounds. The 1 lb version is 1/8 inch thick and comes as either a 4-by-10-foot roll weighing about 42 pounds or a 4-by-25-foot roll weighing about 102 pounds. The 2 lb version is 1/4 inch thick, covers 4 by 15 feet and weighs about 122 pounds.
Those are substantial rolls. The 1 lb option is the most flexible starting point for a conventional wall or barrier, while 2 lb material provides more surface mass where weight, framing and budget allow. The 1/2 lb version is easier to bend and suspend for lightweight or irregular applications.
You can see the specifications and the limitations in our full TotalMass MLV review. The manufacturer also publishes its current dimensions and test information on the TotalMass product page.
ArrowZoom sheet and tile formats
ArrowZoom’s KK1146 is a 1-by-1-meter sheet supplied rolled. It covers roughly 10.8 square feet, and the seller lists a surface weight of 2 lb per square foot and a total sheet weight near 22 pounds. Its size makes it easier to cut around a door panel, machine enclosure, pipe, wheel arch or other shape that would be inconvenient to handle with a full construction roll.
The KK1246 version divides the material into 12-by-12-inch tiles. Packs of 1, 6, 12 and 24 tiles are shown, with each tile covering one square foot and weighing about two pounds. Tiles are convenient for spot coverage, but every joint becomes a potential sound leak. Plan to butt the edges carefully and seal them rather than treating the pieces like decorative acoustic foam.
ArrowZoom currently shows 1.2 mm and 2 mm selections alongside its 2 lb-per-square-foot wording. Because the combination of thickness, surface weight, pack size and marketplace variant can change, verify the selected specification before ordering. Our detailed ArrowZoom MLV review explains these buying checks and the difference between the roll and tiles.

Can You Compare the STC Ratings Directly?
No. A bigger number does not automatically make ArrowZoom or TotalMass the better sound barrier in your room.
TotalMass lists standalone ratings of STC 22 for its 1/2 lb material, STC 27 for 1 lb and STC 32 for 2 lb. Its current product information says the data comes from third-party accredited laboratory testing, with complete reports available on request. The same source also shows that the installed result varies with the wall or ceiling assembly.
ArrowZoom lists STC 31–33 for its 2 lb sheet and tiles, but its performance table identifies the figures as an internal engineering estimate under reference AZ-MLV-INT-REV01. That is not the same evidence as a linked independent laboratory report. The seller also states that actual performance depends on seams, fastening, perimeter sealing and the complete assembly.
For a fair comparison, look first at surface weight, verified coverage and installation quality. Then ask whether the quoted rating applies to the bare material or to a finished wall. A standalone sheet rating cannot predict exactly how many decibels will disappear in your home.
Coverage, Seams and Handling
TotalMass has the clear advantage on a large wall. A 4-foot-wide roll can span framing and reduce the number of joints that need sealing. Fewer seams make it easier to create the continuous, airtight layer required for reliable airborne-sound control.
The drawback is physical handling. A 102- or 122-pound roll is not a casual one-person ceiling installation. You need a safe lifting plan, temporary support and fasteners that distribute the load without tearing the vinyl. Even the 42-pound short roll can become awkward when it is unrolled against framing.
ArrowZoom reverses those tradeoffs. A 22-pound sheet is easier to carry to a vehicle, closet or workshop, and a two-pound tile is simple to position. However, a 100-square-foot wall would require roughly ten KK1146 sheets or one hundred one-square-foot tiles before allowing for waste. That creates far more seams than one TotalMass roll.
Installation: Neither Product Is Self-Adhesive
Older descriptions sometimes call ArrowZoom self-adhesive, but the current MLV listings do not include a built-in peel-and-stick backing. ArrowZoom’s own installation steps call for separate double-sided tape, construction adhesive, staples or screws. TotalMass likewise requires mechanical fasteners or a suitable adhesive for the application.
- Measure the surface and calculate coverage before ordering.
- Plan the fewest practical seams and allow material around edges and penetrations.
- Cut MLV with a sharp utility knife or suitable heavy-duty scissors on a protected surface.
- Support heavy sheets while fastening them. Use washers, cap fasteners or another method that spreads the load where required.
- Butt or overlap seams according to the assembly plan, then seal every joint, perimeter gap and penetration.
- Cover the barrier with the intended finish layer if the installation requires protection or a finished appearance.
Do not rely on a few pieces of ordinary tape to support a heavy overhead sheet. Adhesive compatibility, substrate condition, temperature and fire requirements all matter. For a wall or ceiling inside a regulated assembly, follow the project specification and local code rather than assuming that a general product-page statement proves compliance.
Best Uses for TotalMass and ArrowZoom
Walls and ceilings
TotalMass is usually the practical choice when you need broad, continuous coverage behind drywall or across framing. Its wider rolls reduce joints, and the three weight options let you balance mass against handling. ArrowZoom can cover a small wall section, but its compact format becomes inefficient as the surface grows.
Doors, enclosures, pipes and ducts
ArrowZoom’s cut-to-fit sheet can make sense for a solid, supported door panel, generator enclosure, workshop machine or irregular mechanical surface. TotalMass is still suitable, particularly when you have several items to wrap or want lighter 1/2 lb material. Do not overload door hinges, removable panels or thin covers without checking their capacity.
Vehicles
Both brands can be considered for vehicle applications; the old claim that TotalMass should never be used in automobiles is too broad. ArrowZoom is easier to buy in a compact amount and cut around contours. TotalMass gives you more weight choices if you are planning a larger build. In either case, account for total added weight, heat, moisture, fastener safety and interference with wiring, airbags, drains or moving parts.
Where neither one is the complete answer
MLV primarily helps control sound transmission when it forms part of a suitable barrier. It is not an acoustic treatment for reducing echo inside a room; absorptive panels are used for that job. It is also not a reliable standalone cure for footfall or impact noise, which usually requires isolation, resilient underlayment or changes to the floor-ceiling assembly.
MLV also cannot compensate for an open door gap, unsealed outlet, shared duct or other flanking path. Seal obvious air paths and understand the existing assembly before paying for more material.
What to Check Before Buying
- Surface weight: Compare pounds per square foot, not simply the roll’s total weight.
- Coverage: Include cutting waste, overlaps and the number of packs required.
- Exact variant: Confirm dimensions, thickness and quantity on the final checkout page.
- Installation supplies: Budget for suitable fasteners, washers, adhesive, seam tape and acoustical sealant.
- Supporting structure: Make sure walls, ceilings, doors and panels can carry the added load.
- Documentation: Request the applicable test report or certification file when a project requires verified performance or code compliance.
- Shipping and returns: Heavy MLV can be expensive to return, so inspect the listing carefully before ordering.
If TotalMass suits your project, check the current TotalMass MLV listing on Amazon. For compact ArrowZoom material, check the ArrowZoom MLV product family on Amazon. Prices, availability and marketplace variants change, so match the dimensions and surface weight to this comparison rather than relying on the listing title alone.
If neither format looks right, compare more roll sizes and manufacturers in our guide to the best mass loaded vinyl brands.
Pros and Cons
TotalMass
- Pros: Three surface-weight options, large coverage, fewer seams and published standalone ratings.
- Cons: Heavy rolls, more difficult overhead handling and potentially more material than a small repair needs.
ArrowZoom
- Pros: Compact quantities, manageable pieces and convenient formats for small or irregular surfaces.
- Cons: More seams on large areas, variant details need careful checking and the STC 31–33 claim is an internal estimate rather than independently verified data linked on the listing.
Frequently Asked Questions
Is ArrowZoom MLV self-adhesive?
No. The current KK1146 sheet and KK1246 tiles require separate double-sided tape, construction adhesive or mechanical fasteners. Do not confuse them with ArrowZoom foam products or mounting accessories that may be self-adhesive.
Is 2 lb MLV always better than 1 lb MLV?
Not always. The heavier material adds more surface mass, but it also doubles the nominal load per square foot and is harder to support. A well-sealed 1 lb installation in an appropriate assembly can be a better project decision than poorly installed 2 lb material.
Which product is easier for one person to install?
ArrowZoom’s tiles are the easiest pieces to handle, followed by its roughly 22-pound sheet. TotalMass rolls cover more area but commonly require at least one helper, especially on walls and ceilings.
Can I leave MLV exposed?
That depends on the location, appearance, durability requirements and applicable code. MLV is commonly concealed in finished wall assemblies. In utility areas it may be exposed when the product and installation are suitable, but it still needs secure support and protected edges.
SPD Verdict
Choose TotalMass for a large, continuous construction barrier. Its roll widths, coverage and 1/2, 1 and 2 lb options make it easier to specify for a full wall, ceiling or multi-surface project.
Choose ArrowZoom when compact handling matters more than square-foot efficiency. The current sheet and tile formats suit a door, enclosure, vehicle section or other small and irregular area. Just remember that they are not self-adhesive and that the advertised STC range is an internal estimate.
Whichever product you choose, continuous coverage and careful sealing matter more than the logo on the vinyl.
Good luck and happy soundproofing!
