Trademark Soundproofing 1lb MLV — 4′ x 25′ (Outdoor-Ready)
Product overview: A dense mass-loaded vinyl barrier designed for walls, floors, ceilings, and outdoor installations. Features a 1/8 inch thick rubberlike composition with a density of 1 pound per square foot, delivering solid sound reduction. The material is described as environmentally safe, non-toxic, and made from virgin materials with no regrind or recycled content. Its 27 STC rating (as stated) makes it a reliable choice for exterior boundaries where wind-driven noise, traffic, or equipment noise penetrates.
Trademark Soundproofing 1lb MLV — 4′ x 25′ (Outdoor-Ready) Details
Key specs: 1 lb per square foot density provides substantial mass for barrier walls and outdoor fences. Uses virgin material, designed to avoid odors, and is described as suitable for long-lasting exterior use where wind and weather are considerations. Installation typically involves attaching the MLV to existing structures in outdoor boundaries or as an interior layer behind weatherproof panels.
Trademark Soundproofing 1lb MLV — 4′ x 10′ (Outdoor)**
Product notes: Similar 1 lb/sq ft density with a 27 STC rating, optimized for wall, floor, and ceiling soundproofing, with a focus on non-toxic virgin material. This variant comes in a more compact panel size, which may suit smaller exterior projects or retrofit work on fences and sheds where larger rolls aren’t practical.
VinylX Reinforced MLV — 48″ x 16′ Roll
Product highlights: A premium VLV roll rated for outdoor use, designed to deliver strong noise blocking with a stiff but flexible formulation that can adapt to outdoor fencing, walls, or other exterior barriers. Includes a reinforced scrim and a durable gray embossed finish for a professional look. Features an ASTM Class B fire-rating advisory for safety in utility spaces. This option is intended for robust exterior sound barriers where high mass and outdoor resilience are needed.
TroyStudio Mass Loaded Vinyl — 1′ x 8′ Sheet
Overview: A compact outdoor-capable MLV solution with 1 lb per sq ft density and a 1/8 inch thickness, offering a high STC rating around 28. The sheet form factor is practical for DIYers working on fences, utility enclosures, or small outdoor noise barriers. The product emphasizes vibration damping, flexibility, and suitability for both outdoor and indoor installations, with a flame retardant and eco-friendly profile.
EnviroFlex 1 LB MLV — 4’ x 10’ Roll
Notes: EnviroFlex presents a 26 STC rating in a 1 lb/sq ft density roll, sized 4×10 feet for flexible outdoor installations—fences, exterior walls, or vehicle housing. It emphasizes professional-grade soundproofing with easy-cut, screw- or adhesive-installation compatibility. The roll format supports quicker coverage of longer exterior boundaries.
Tönnen Mass Loaded Vinyl — 4’ x 20’ Roll
Product details: A premium density MLV variant rated at 1.23 lb/ft², offering a STC rating of 32 for superior sound blocking. The larger 4×20 roll targets broad exterior surfaces, with a noted advantage of higher density delivering greater noise reduction per square foot. The packaging emphasizes strong surface compatibility and installation ease for walls and enclosures exposed to outdoor noise.
Buying Guide: Key Points When Choosing Outdoor Mass Loaded Vinyl
- Sound Transmission Class (STC): Higher STC numbers indicate better noise reduction. Outdoor environments benefit from higher STC ratings, especially near traffic or industrial noise sources.
- Density and Thickness: Common densities range from 1 lb/ft² to around 1.23 lb/ft². Greater density means more mass and better sound blocking, but heavier rolls may be harder to handle.
- Roll vs. Sheet Format: Rolls are ideal for lengthy exterior barriers, fences, or walls; sheets suit retrofit work or smaller projects with precise cuts.
- Weather Resistance: Look for materials advertised as outdoor-ready or UV-stable. Outdoor installations require durable, weather-resistant backing and sealers as needed.
- Installation Method: Most MLVs install with screws, staples, or strong adhesives. Ensure substrate compatibility and consider vibration dampening needs for exterior structures exposed to wind vibration.
- Fire Rating: Some products include fire-class ratings (e.g., ASTM Class B). For exterior enclosures or utility areas, fire safety considerations may be required.
- Environmental Considerations: Virgin-material formulations are often preferred for odor-free use and long-term stability in outdoor settings.
- Cost vs. Coverage: Compare price per square foot and total project coverage. Heavier rolls may reduce the frequency of seams but require more handling.
- Compatibility with Surroundings: For visible exterior barriers, aesthetic finishes and finishes that blend with outdoor environments can matter.
In outdoor installations, combining MLV with other barriers (e.g., weatherproofing membranes, fencing, and decoupling structures) can enhance performance. Always follow manufacturer installation guidelines and local building codes for outdoor noise barriers.
