The bottom line: buy this if you want a light, strong insulation that reflects up to 97% of radiant energy and doubles as a vapor and sound barrier. It is especially valuable where radiant heat is the main problem, such as attics, roofs, radiant floors, and metal buildings, and the review found it straightforward to cut, fit and tape during install.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRadiant reflection:\u003c\/strong\u003e Reflects up to 97% of radiant energy so interior spaces stay cooler in summer and retain heat in winter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh R-value:\u003c\/strong\u003e Provides up to R-15.67 with one layer and improves to about R-21.10 with two layers for improved thermal performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVapor barrier:\u003c\/strong\u003e Acts as a vapor barrier to prevent condensation and is unaffected by humidity and moisture, protecting assemblies from dampness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound dampening:\u003c\/strong\u003e The closed cell foam core also reduces airborne noise, making it useful as a sound barrier in walls and ceilings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable construction:\u003c\/strong\u003e 5 mm closed cell polyethylene foam is sandwiched between pure aluminum on both sides for a strong but lightweight commercial-grade panel that is easy to cut and install.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety and comfort:\u003c\/strong\u003e Fire rated Class 1\/Class A and non toxic, so it will not irritate skin, eyes or throat during handling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe SmartSHIELD roll is best for homeowners, builders and HVAC professionals installing insulation in attics, roofs, steel buildings, pole barns, radiant concrete floors, crawl spaces and retrofits where a reflective barrier is important.
