The INSULATION MARKETPLACE SmartSHIELD -3mm Reflective Insulation roll is designed to improve window insulation by reflecting up to 95% of radiant heat, making it a strong radiant barrier. It’s made from 3mm thick closed-cell polyethylene foam, which is denser and more durable than typical bubble wrap insulation, sandwiched between reflective foil layers. This thickness helps add insulation and sound dampening, reducing outside noise effectively. The roll covers 625 square feet, sized at 48 inches wide by 25 feet long, providing ample coverage for multiple windows or a large area.

It’s lightweight, easy to cut and install, and resists moisture and humidity, so it can be used both indoors and outdoors without damage. This product does not have a sticky adhesive backing, so you’ll need to use tape or other fasteners to attach it to your windows or walls. The material is non-toxic and safe to handle, which is a plus for indoor use.

This insulation suits homeowners looking to reduce heat loss and noise with a durable, reflective barrier that’s easy to manage. For those seeking an all-in-one adhesive solution or explicit UV protection, other options may be more suitable.

The SmartSHIELD -5mm Reflective Insulation Roll is a comprehensive solution for various insulation needs, including window applications. Its primary strength lies in its ability to reflect 95% of radiant energy, boasting high R-values (up to 21.10 with two layers). This makes it highly effective for both summer cooling and winter heating, potentially reducing energy costs significantly. The material thickness of 5 millimeters offers robust insulation without being overly bulky.

It is both tear and puncture-proof yet easily cuttable with scissors, adding convenience to its installation process. The product doubles as a vapor barrier, preventing condensation and resisting humidity and moisture, which is particularly beneficial in varying climates. Additionally, it meets stringent ASTM standards, including a Class A Fire Rating, ensuring safety and durability. The engineered foil surface has a proprietary clear coating for corrosion resistance, adding to its longevity.

While it excels in radiant heat reflection, it lacks features like adhesive backing, which might necessitate additional materials for secure attachment on windows. The size of 48 inches by 50 feet provides ample coverage, suitable for larger projects but may require customization for smaller windows. The user-friendly nature, reflected in its non-toxic composition and wide range of applications, makes it versatile beyond just window insulation, including attics, walls, and floors.
