In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

This roll of Reflectix reflective insulation covers 200 square feet in a single 4' x 50' roll, giving you enough material for a decent-sized attic or wall project without buying multiple rolls. The double-sided reflective facing works as a radiant barrier, bouncing heat away in summer and holding it in during winter, with an R-value ranging from R-3.7 to R-21 depending on how it's installed. It's also vapor retardant and formaldehyde free, making it a solid choice for attics and walls where moisture control matters as much as temperature control.

  • Coverage area: 200 sq. ft. (4' x 50' roll)
  • Thickness: 0.3125 in.
  • R-Value: R-3.7 to R-21
  • Vapor retardant, formaldehyde free
  • Energy Star certified
  • Made in the USA

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
