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.

  • Guaranteed authentic · No counterfeits, no gray-market resellers

About Product Overview

This Owens Corning R21 batt insulation is sized for standard 2x6 wall framing, with kraft facing built in to act as a vapor retarder for the living space side of exterior walls. Each batt measures 23 inches wide by 93 inches long, so it fits between studs spaced 24 inches on center without a lot of trimming or fitting work. The fiberglass construction delivers an R-value of 21, giving walls a solid thermal barrier against heat loss and heat gain.

One package covers 89.13 square feet, which helps when you're estimating how many bundles a wall section or room addition will need. This is a good fit for new construction, room additions, or wall cavities being opened up during a remodel where you want to bring insulation levels up to current standards. 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.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
