Introduction
When comparing mass loaded vinyl barriers with a 1 lb per square foot density, two commonly considered options are the Soundsulate Next Generation and the TroyStudio Mass Loaded Vinyl. Both are positioned as dense, flexible sound barriers, but they differ in material composition, size format, vibration characteristics, and installation context. This comparison focuses strictly on what is stated in their respective reviews to clarify how each product is described and where their specifications diverge.
Key Decision Factors Identified From the Review Content
The review content highlights measurable differences in sheet size, thickness, STC rating, material construction, and vibration control capability, along with variations in environmental resistance and intended installation contexts.
- Material composition (PVC vs rubber/polymer blend with fabric backing)
- Sheet dimensions and total coverage per unit
- STC rating (27 vs 28)
- Vibration dampening support
- Waterproof and flame-retardant properties
Soundsulate Next Generation 1 lb Mass Loaded Vinyl Soundproofing Roll for Walls Ceilings and Automotive Overview
The Soundsulate Next Generation is described as a PVC-based mass loaded vinyl barrier with an area density of 1 lb per square foot. Each sheet measures 4 feet by 8 feet, providing 32 square feet of coverage and weighing 32 pounds. The listed thickness is approximately 0.12 inches (1/8 inch).
It carries a published STC rating of 27 and is positioned for use behind drywall, under floors, inside doors, and in automotive interiors. The review specifies that it is not intended to mitigate impact noise or structural vibration. Installation may require mechanical fasteners or acoustical adhesives, and full surface coverage is emphasized for performance.

TroyStudio Mass Loaded Vinyl Sound Proof Barrier 1 lb/sqft MLV Insulation Sheet Overview
The TroyStudio Mass Loaded Vinyl is described as a dense soundproofing sheet with an area density of 1 lb per square foot and a thickness of approximately 0.13 inches. Each sheet measures 1 foot by 8 feet, providing 8 square feet of coverage and weighing about 8 pounds.
Its construction includes high-damping rubber combined with polymer metal powder and a nonwoven fabric backing. The stated STC rating is 28. In addition to airborne sound reduction, the rubber composition is described as supporting vibration dampening. The product is also listed as waterproof and flame retardant with a B1 rating.
Further installation and application details are outlined in the full review of the TroyStudio Mass Loaded Vinyl.
Head-to-Head Comparison: What the Evidence Shows
Both products are rated at 1 lb per square foot and are positioned as flexible barriers for adding mass to walls, ceilings, and enclosures. However, their material composition differs significantly. Soundsulate is described as PVC-based, while TroyStudio uses a rubber and polymer metal powder blend with a fabric backing.
The STC ratings are close but not identical: Soundsulate is listed at 27, whereas TroyStudio is listed at 28. Thickness is also slightly different, at approximately 0.12 inches for Soundsulate and 0.13 inches for TroyStudio.
In terms of physical format, Soundsulate provides a larger 4 ft by 8 ft sheet totaling 32 square feet per unit, while TroyStudio comes in a narrower 1 ft by 8 ft sheet with 8 square feet of coverage. The reviews also distinguish their vibration positioning: Soundsulate is not intended for impact or structural vibration mitigation, whereas TroyStudio is described as supporting vibration dampening.
Environmental properties further separate them, as TroyStudio is specifically identified as waterproof and flame retardant with a B1 rating. Equivalent classifications are not specified in the Soundsulate review.

Which One May Be the Better Fit for Different Situations
Based on the review descriptions, the Soundsulate Next Generation may align with projects requiring larger sheet coverage in a single panel format, such as wall or ceiling assemblies, and where PVC construction is preferred. It is also explicitly described as not intended for structural vibration control.
The TroyStudio Mass Loaded Vinyl may be considered in scenarios where vibration dampening is a stated objective, or where waterproof and flame-retardant properties with a B1 rating are relevant. Its narrower sheet format may suit installations where smaller sections are needed.
