1. Introduction
Choosing between Frienda 1.33 x 13 ft Mass Loaded Vinyl Soundproofing Roll for Walls and Ceilings and AcoustiBlok MLV Review mainly comes down to how each product is positioned and specified in the write-ups. The Frienda roll is described with a fixed roll size and simple spec callouts (2mm thickness and 1 lb/ft²), while AcoustiBlok is described as a construction-focused product line with two variants (Blok16 and Blok32) and stated STC values.
- Form factor: Frienda is described as a flexible roll sized 1.33 x 13 ft (21 sq ft); AcoustiBlok is described as sheets/rolls commonly referenced at 54 inches wide and 30 feet long, with longer lengths available.
- Stated mass/thickness options: Frienda is described as 2mm and 1 lb/ft²; AcoustiBlok is described in two forms (Blok16 at 1/8″ and 1 lb/ft², Blok32 at 1/4″ and 2 lb/ft²).
- Ratings included: AcoustiBlok’s write-up includes STC values for Blok16 and Blok32; Frienda’s write-up does not list STC values.
- Installation context: AcoustiBlok is described as typically applied during construction/remodeling over bare studs; Frienda is described for joist, wall, ceiling, or floor installations with common fastening methods mentioned.

2. Key Decision Factors Identified From the Review Content
The review content emphasizes differences in stated specifications (thickness, weight per square foot, and the presence of STC values), the way each product is framed for installation timing (general installations vs. construction/remodeling over studs), and the physical format and sizing described (a smaller fixed roll vs. larger sheet/roll dimensions with longer length options).
3. Frienda 1.33 x 13 ft Mass Loaded Vinyl Soundproofing Roll for Walls and Ceilings Overview
The Frienda MLV Roll is described as a 1.33 x 13 ft mass-loaded vinyl barrier that provides 21 square feet of coverage. The write-up specifies a 2mm thickness and a 1 lb per square foot sound barrier, presented as a flexible roll intended for wall, ceiling, floor, or joist installations.
In terms of composition, the Frienda material is described as a rubber-based compound designed for high density and damping performance, in a black, flexible roll format. If you want to see the exact product listing referenced in the write-up, you can open Frienda alongside the specs described above.
4. AcoustiBlok MLV Review Overview
The AcoustiBlok MLV write-up describes the product as a viscoelastic construction polymer offered in two forms: Blok16 and Blok32. It specifies Blok16 as 1/8″ thick at 1 lb per square foot and Blok32 as 1/4″ thick at 2 lb per square foot, and it lists STC values of 26 (Blok16) and 32 (Blok32).
The content frames AcoustiBlok as typically applied during construction or remodeling, installed over bare studs for walls or ceilings before finishing layers are completed. It also describes the material as made from recycled plastics and benign minerals compressed into a sheet, black in color, and noted for high UV resistance with a chemical combination that disallows fungal and algal growth. For sizing, it describes sheets usually being 30 feet long and 54 inches wide, with longer roll lengths available (60 up to 350 feet), and references an approximate roll weight of 135 pounds for the 30 ft x 54 in size.
5. Head-to-Head Comparison: What the Evidence Shows
Specs and options called out: The Frienda write-up provides a single set of headline specs (2mm thickness and 1 lb/ft²) tied to one roll size. The AcoustiBlok write-up describes two variants with different thickness and weight (Blok16 and Blok32) and includes STC values for each.
Physical format and sizing described: Frienda is presented as a 1.33 x 13 ft flexible roll (21 sq ft coverage). AcoustiBlok is presented with “usually” referenced sheet dimensions (30 feet long and 54 inches wide), optional longer roll lengths, and a stated approximate roll weight at the typical size.
Installation timing/context: Frienda is described for joist, wall, ceiling, or floor installations with multiple attachment methods mentioned. AcoustiBlok is described as typically applied during construction/remodeling over bare studs, before walls/ceilings/floors are completed.
Material description: Frienda is described as rubber-based. AcoustiBlok is described as a viscoelastic construction polymer made from recycled plastics and benign minerals compressed into a sheet, with additional statements about UV resistance and preventing fungal/algal growth.

7. Which One May Be the Better Fit for Different Situations
Frienda may be more suitable when you want a single, fixed-size roll called out by the write-up (1.33 x 13 ft, 21 sq ft coverage) with a stated 2mm thickness and 1 lb/ft² barrier description. If that matches what you’re comparing, reviewing the listing for Frienda can help you confirm you’re looking at the same roll format described.
AcoustiBlok may be more suitable when you want variant options that are explicitly differentiated in the write-up (Blok16 vs. Blok32) with stated thickness, weight per square foot, and STC values. It is also positioned as being typically applied during construction or remodeling over bare studs, with commonly referenced sheet/roll dimensions and longer roll-length options described.
8. Frequently Asked Questions
Do both products list the same core specifications in the write-ups?
No. The Frienda write-up lists 2mm thickness and 1 lb/ft² tied to a 1.33 x 13 ft roll, while the AcoustiBlok write-up lists two variants (Blok16 and Blok32) with different thickness/weight values and includes STC values for each.
Is either product described with STC values?
Yes. The AcoustiBlok write-up lists STC 26 for Blok16 and STC 32 for Blok32. The Frienda write-up does not include STC values.
How do the write-ups describe installation context?
The Frienda write-up describes use in joist, wall, ceiling, or floor installations and mentions trimming and multiple fastening approaches. The AcoustiBlok write-up describes it as typically installed during construction or remodeling over bare studs before walls, ceilings, and floors are completed.
Are the materials described the same way?
No. Frienda is described as a rubber-based compound. AcoustiBlok is described as a viscoelastic construction polymer made from recycled plastics and benign minerals compressed into a sheet, with additional statements about UV resistance and preventing fungal and algal growth.
Do both write-ups provide clear roll/sheet sizing?
They provide sizing in different ways. Frienda is described as a 1.33 x 13 ft roll (21 sq ft coverage). AcoustiBlok is described with a “usually” referenced size of 30 feet long and 54 inches wide, plus optional longer roll lengths from 60 to 350 feet.
9. Closing Guidance
If your decision hinges on a single roll size and a straightforward set of stated callouts (2mm thickness, 1 lb/ft², and 21 sq ft coverage), the Frienda write-up presents the product in that format. If your decision hinges on choosing between two explicitly defined variants with stated thickness, weight per square foot, and STC values, the AcoustiBlok write-up is structured around that Blok16 vs. Blok32 choice.
