Design Engineering Boom Mat Deadening Spray
DESIGN ENGINEERING’s Boom Mat Deadening Spray offers superior noise reduction by addressing road noise, squeaks, and vibrations. Its versatility includes interior and exterior use, enabling treatment of trunk interiors, fender wells, undercarriages, rear quarters, and door panels. A key advantage is moisture sealing to prevent rust, contributing to longer-lasting performance in varied climates. The product dries quickly—about 20 minutes—and can be painted over within six hours, allowing color-matched or color-coordinated installations. It adheres to a wide range of surfaces, including non-coated materials, making it a practical option for both new builds and upgrades.
Features summarized: strong noise reduction, broad application areas, moisture sealing, fast drying, and paintability. When applying, ensure proper ventilation and follow safety guidelines for spray products. This solution aims to improve cabin quietness and audio clarity by minimizing structural vibrations that propagate sound through metal panels and panels’ seams.
BEEST FullStop Spray Foam Insulation Kit
BEEST FullStop is a comprehensive spray foam insulation kit designed for walls and attics, offering strong thermal insulation and notable acoustic benefits. The kit markets an impressive R-value of 8.14 with a 2-inch thickness and includes 12 spray cans, a professional-grade spray gun, a solvent-based cleaner, gloves, goggles, and a coverall. This kit targets hard-to-reach spaces and irregular surfaces, expanding to seal gaps, cracks, and joints. While primarily marketed for building projects, its high coverage and robust sealing capabilities can make a significant difference in reducing ambient sound transmission in enclosed spaces and structures, including basements or attics adjacent to living areas.
Important considerations include safety gear use and correct curing conditions to maximize performance. This option suits homeowners seeking broader acoustic and thermal control beyond automotive applications, especially in compact or irregular spaces where sound leaks are common.
Design Engineering Boom Mat Spray-on (18 oz, 3 Pack)
This three-pack brings Boom Mat spray-on sound deadening to multiple areas of a vehicle or project. The product is designed to reduce road noise and vibration, with a focus on interior applications. It is formulated to resist cracking or chipping and also aids in rust prevention. Its paintable surface in about six hours provides the flexibility to match interior aesthetics while maintaining acoustic benefits. The spray’s formulation emphasizes durable coverage across tight or irregular spaces, helping to create a more comfortable, audio-friendly environment inside the vehicle or space being treated.
ATAC Advanced Thermal Acoustic Coating
ATAC Advanced Thermal Acoustic Coating blends heat reflection with noise dampening using micro-sphere ceramic technology. The two-in-one approach aims to form a thermal barrier while dampening NVH (noise, vibration, and harshness). Coverage is listed around 75 square feet, making it a practical option for larger panels, floors, or trunk areas where heat transfer and noise infiltration occur. The spray-on ceramic formula is designed for flexible application on metal, fiberglass, and select plastics, easing treatment of hard-to-reach zones like firewall and transmission tunnels. This coating provides a balanced solution for reducing heat gain and sound transfer, contributing to a cooler, quieter ride or living space.
Design Engineering ATAC Advanced Thermal Acoustic Coating
ATAC is highlighted for its durable, 2-in-1 capability: it serves as both a heat-blocking and sound-dampening coating. The product leverages ceramic micro-sphere technology to reflect heat up to 375°F while reducing noise and vibration. It is positioned as a spot-treatment solution for tight, irregular spaces, leveraging its flexible adhesion to metal, fiberglass, and some plastics. Coverage per can is roughly 12 square feet, which supports precise, targeted application rather than blanket coverage. This makes ATAC suitable for professional-level, site-specific noise reduction in automotive or industrial environments where space and access are limited.
Design Engineering 050220 Boom Mat Spray-on Sound Deadening
This 18-ounce, six-pack variant of Boom Mat Spray-on is designed to reduce road noise and vibration, with a focus on hard-to-reach areas. It emphasizes durability, stating that the coating won’t crack or chip and can help prevent rust. The product’s paintable property after curing provides a flexible fit for aesthetic maintenance, especially in visible areas where an unobtrusive finish is desired. The six-pack offers extended coverage for broader projects, enabling a more comprehensive quieting approach across the vehicle or structure being treated.
Buying Guide: Key Purchase Considerations
- Target area and space: For automotive use, consider areas with high vibration and potential for sound transmission (doors, trunks, wheel wells). For buildings, focus on walls, ceilings, and attics where air leaks and sound travel are most evident.
- Coverage and can size: Larger spaces require higher coverage products (e.g., BEEST FullStop) or multi-can packs. For spot treatments, single cans or small packs (like Boom Mat or ATAC) are effective.
- Material compatibility: Check surface compatibility (metal, fiberglass, plastics) and whether the coating is paintable to ensure a uniform finish in visible areas.
- Thermal vs. acoustic balance: Some products emphasize heat reflection (ATAC) alongside noise reduction, while others prioritize acoustic damping with less emphasis on temperature control.
- Drying and curing times: Quick-drying sprays enable faster projects but ensure sufficient curing before handling or painting, typically within hours.
- Safety and ventilation: Spray products require proper ventilation and protective gear. Review safety data sheets and usage instructions for best results and safety.
- Durability and maintenance: Look for formulations that resist chipping, cracking, and moisture-related corrosion to maximize long-term quietness and structural integrity.
- Application versatility: Some products are suitable for interior and exterior use or for irregular surfaces, which expands potential applications beyond strict automotive use.
- Noise reduction vs. energy efficiency: In building applications, consider whether acoustic dampening is paired with thermal insulation to curb energy costs and improve comfort.
