SmartSHIELD -5mm 48″ x50ft Reflective Foam Core Roll
This roll combines insulation with a radiant barrier and vapor/sound protection in a single layer. It reflects up to 95% of radiant energy, delivering an effective R-value up to 15.67 with a single layer. The product features a clean white surface that requires no painting and eliminates the need for additional insulation on affected ceiling areas. It’s designed for quick retrofit into basement ceilings where space is limited and ease of installation matters. The combined barrier helps suppress heat transfer from warm summers and cold winters while reducing moisture migration.
SmartSHIELD -3mm 48inx25ft Reflective Foam Core Roll
Designed as a versatile radiant barrier with vapor and sound protection, this 3mm roll provides effective reflectivity of radiant energy while maintaining humidity resilience. Suitable for mixed-use basement ceilings where moisture control and noise dampening are priorities, it functions well in indoor applications as well as sheltered outdoor installations. The product helps reduce temperature swings and can contribute to a more comfortable basement living area without requiring bulky additional layers.
SmartSHIELD -20mm 48″ X25ft Foam Core Roll
This thicker insulation roll delivers a high R-value (up to 23 with one layer and up to 29 with two layers), making it suitable for basements with significant cold exposure or where winter comfort is a priority. It also functions as a vapor barrier to reduce condensation and includes a fire-rated barrier suitable for standard building codes. Its robust aluminum-foil surface helps minimize radiant heat transfer and offers durable performance for ceiling installations in colder climates.
SmartSHIELD -5mm 24”X25ft Foam Core
With a 5mm foam core, this 24-by-25-foot roll offers strong radiant reflection, delivering up to a 15.67 R-value per layer. It also serves as a vapor barrier, protecting against condensation, and includes sound-damping properties to reduce noise transmission. Ideal for compact basement ceiling applications where space and performance are both critical, this option supports quicker installations and energy efficiency gains without sacrificing comfort.
SmartSHIELD -1.5mm 48″ x100ft Roll
This extended 100-foot roll expands coverage for larger basement ceilings while maintaining a radiant barrier, vapor barrier, and energy-saving design. It reflects up to 95% of radiant energy and helps lower heat transfer between floors and spaces. The product emphasizes moisture resistance and a cost-effective approach to achieving a more stable basement climate over time.
Halero 5mm Reflective Insulation Foam Core
Halero’s 5mm foam-core solution emphasizes a double-sided aluminum foil barrier with high radiant reflectivity. It supports both indoor and outdoor installations, including ceilings, walls, and roofing. The product highlights a variety of uses from residential basements to steel buildings, with an emphasis on energy savings and a compact, lightweight installation profile. Note that this option is included here for broader context, though it is not among the five primary selections above.
Buying Guide: Key Purchase Considerations
- Radiant barrier performance: Look for products that reflect a high percentage of radiant energy (usually around 95% or more) to reduce heat transfer from upper spaces to the basement.
- R-value per layer: Single-layer R-values around 15–23 are common for basement ceilings when using reflective foam-core panels; consider multi-layer options for harsher climates.
- Vapor barrier capability: Basements are prone to moisture; choose products with vapor barrier properties to minimize condensation and mold risk.
- Sound attenuation: If the basement is used as a living space, select materials with sound-dampening features to reduce noise transmission between floors.
- Fire safety and building codes: Check for Class A Fire Rating or equivalent, and ensure the product meets local standards for basement installations.
- Installation practicality: Foam-core and foil-faced rolls should be easy to cut and fit around joists, ductwork, and light fixtures; consider product weight and handling when choosing DIY-friendly options.
- Durability and moisture resistance: Outdoor-use capabilities can be beneficial in attach-and-forget installations, but ensure compatibility with indoor basement environments.
- Cost-to-performance balance: Compare R-values, barriers, and coverage to estimate total material costs and long-term energy savings for your space.
- Warranty and certifications: Look for supplier warranties and any third-party testing that confirms adherence to ASTM standards or building codes.
