Thermal And Fire Resistance: The foam contributes to cold protection and energy efficiency by reducing heat transfer. The material is designed to be waterproof and self-extinguishing, supporting safer use in various environments.
Sprayman Spraycoat Fire Rated Foam
Class-A Fire Rated & Energy Saving: A closed-cell polyurethane spray foam offering flame resistance (ASTM E84) and significant reductions in heating and cooling costs. Suitable for roofs, walls, basements, and tanks, it helps create a safer, more energy-efficient envelope.
Durability And Application: The foam cures into a rigid structure that resists cracking and settling, maintaining insulation performance over time. Includes a dual-nozzle system to simplify vertical and horizontal spraying, with paintable cured surfaces.
Owens Corning 703 Fiberglass Boards
Fiberglass Acoustic And Thermal Board: Sold as a 6-pack of 2-inch boards, these semi-rigid panels provide a reliable thermal barrier with a Noise Reduction Coefficient (NRC) of 1.0 for effective sound absorption. Useful for walls, ceilings, and other interior applications where space allows.
R-Value And Safety: The boards offer a strong heat resistance and contribute to improved energy efficiency, while maintaining fire-safe performance appropriate for building assemblies and retrofit projects.
SmartSHIELD -5mm Reflective Insulation Roll
Radiant Barrier And Vapor Control: This 5 mm reflective insulation roll reflects up to 95% of radiant energy, delivering an effective radiant barrier for both heat protection and condensation reduction. It acts as a vapor barrier for moisture control in various installations.
ASTM And Fire Standards: The product meets or exceeds ASTM C1313 Class A fire rating with a corrosion-resistant engineered foil surface, aligning with typical building code expectations for high-performance insulation projects.
Buying Guide: Key Purchase Considerations
- Application fit: Choose products based on your project—automotive heat and noise management vs. home or workshop insulation. Consider whether you need radiant barriers (foil faced) or bulk insulation (foam or fiberglass).
- Thermal performance: Look for R-values or radiant heat reflection capabilities. Closed-cell foams offer strong moisture resistance and higher density, while fiberglass provides good acoustic absorption with lower density.
- Acoustic benefits: If sound reduction is primary, prioritize high NRC values and denser foams or fiberglass with proven acoustic performance.
- Fire safety: For areas requiring fire resistance, select products with Class-A fire ratings or self-extinguishing features. Verify local code compliance where applicable.
- Moisture and durability: In damp environments, moisture resistance and waterproof properties matter. Closed-cell foams tend to resist water absorption better than open-cell options.
- Ease of installation: Self-adhesive liners simplify installation, while spray foams provide seamless coverage but require careful handling and curing guidance.
- Cost per area: Compare price per square foot and installation labor. Some products offer cost advantages at scale due to lower material costs or simplified installation.
- Compatibility: For vehicles, ensure materials adhere well to metal and existing panels without emitting odors or causing compatibility issues with plastics.
This selection aims to balance thermal efficiency, acoustic performance, and safety across automotive and home environments. When choosing, consider the specific climate, installation space, and whether radiant reflection, moisture resistance, or mass insulation best meets your goals.
