VOISEN Sound Deadening Material for Generators
The VOISEN Sound Deadening Material features 4mm thick high density closed cell foam that effectively blocks up to 98% of radiant heat transfer. Its layered composition includes a strong adhesive backing for easy installation. Perfect for extinguishing generator noise and heat, this material also serves as a waterproof vibration deadener providing a quieter environment even in harsh weather. Covering a total area of 36 square feet, VOISEN’s foam mat can be applied to walls, enclosures, or any surface near your generator to reduce noise and temperature effectively.
Siless Liner 4 mm Closed Cell Foam Sound Deadener
Offering excellent value, the Siless Liner is a lightweight and flexible closed cell polyethylene foam designed to be oil and waterproof. It blocks 98% of radiant heat, shielding your generator from excessive warmth. Its adhesive backing ensures a secure fit that minimizes vibration and noise transmission. The foam’s compressibility and no-odor formulation make it an ideal, easy-to-install option for generator enclosures, reducing sound leakage and heat transfer comprehensively.
Soundsulate 1 lb Mass Loaded Vinyl Soundproofing Roll
The Soundsulate 1 lb MLV offers a proven sound blocking performance with a 26 STC rating. Each roll covers 100 square feet and is 0.1 inches thick. This mass loaded vinyl effectively reduces generator noise by blocking airborne sound waves while also acting as a moisture and air barrier. It is non-toxic and easy to cut for customized installations, suitable for large enclosures or walls to significantly lower noise levels.
Soundsulate 2 lb Mass Loaded Vinyl Soundproofing
The Soundsulate 2 lb MLV is a high-density soundproofing option with a 31 STC rating, providing superior noise blocking compared to lighter MLVs. Covering a large area of 520 square feet, it is thicker at 0.2 inches, ideal for heavy-duty noise reduction around generators. It also functions as an air and moisture barrier, which helps preserve the enclosure and enhances insulating properties. Its non-toxic nature makes it suitable for indoor and outdoor applications alike.
Second Skin Luxury Liner 1 lb Mass Loaded Vinyl Sheets
The Second Skin Luxury Liner provides mass loaded vinyl sheets designed for noise blocking with a 26 STC rating. Pre-cut into manageable 24” x 54” sheets, it fits well for building small soundproof boxes or generator enclosures. It is dense, limp, and designed to be airtight for maximum sound blocking. This makes it an excellent choice to create a calm environment around noisy equipment, effectively reducing airborne sounds and vibrations.
Buying Guide for Choosing the Best Sound Barrier for Generators
When selecting a sound barrier for your generator, consider the following key factors to ensure optimal noise and heat reduction:
Material Type and Density
Mass Loaded Vinyl (MLV) is proven highly effective at blocking airborne noise and vibrations due to its density and limpness. Closed cell foam materials are excellent for absorbing vibrations and reducing radiant heat. Choose a material based on your specific soundproofing needs—MLV for blocking sound waves, foam for vibration reduction and thermal insulation.
Thickness and Coverage
Thicker materials generally provide better insulation and soundproofing. MLV products range from 1 lb per square foot (about 0.1 inches thick) to 2 lb per square foot (0.2 inches thick), with higher thickness offering more noise reduction. Foam thickness usually ranges around 4mm. Ensure the coverage area matches the size of the generator enclosure or installation site.
Heat Resistance and Thermal Barrier Properties
Generators generate significant heat; thus, choose a sound barrier that also offers thermal insulation. Closed cell foam materials like VOISEN and Siless provide excellent radiant heat blocking which will help maintain manageable temperatures near the generator and protect nearby surfaces or materials.
Ease of Installation
Look for materials with strong adhesive backing for quick and secure installation. Flexible and lightweight sound barriers simplify handling and conforming to irregular surfaces common in generator enclosures.
Durability and Environmental Resistance
Since generators often operate outdoors, selecting waterproof, oil resistant, and moisture-resistant materials is crucial to prevent degradation. Closed cell foam liners and MLV barriers typically offer such protections to prolong lifespan and maintain soundproofing performance.
Noise Reduction Ratings
The Sound Transmission Class (STC) rating measures a material’s ability to block sound. Higher STC ratings (above 26) indicate better soundproofing. For heavy machinery like generators, materials with STC ratings of 26 or higher are advisable for significant noise reduction.
Application Specific Features
Consider the generator’s environment; for instance, if it operates near living spaces, a higher density sound barrier may be preferred. For smaller generators or enclosures, pre-cut sheets like Second Skin’s Luxury Liner can be convenient.
By evaluating these factors, you can select the best sound barrier that balances noise reduction, heat insulation, installation ease, and cost to create a quieter, cooler generator setup.
