Solid Protection for My Outdoor Kitchen

This 42-inch wall panel from Sunstone is a great addition to my outdoor kitchen setup. The 304 stainless steel feels really sturdy and I can already tell it's going to hold up well to the elements. Installation was pretty straightforward, and it definitely helps keep the heat off the back wall.

Good Heat Barrier, Minor Quibbles

I picked up this Sunstone grill wall panel for my new built-in grill. The heat protection is excellent, exactly what I needed to protect my siding. My only minor complaint is that the smoke deflector could be a little more pronounced for my particular grill, but it still does a decent job.

Does the Job, A Bit Pricey

The 42-inch stainless steel panel does exactly what it's supposed to do – protect the wall behind my grill. The quality of the 304 stainless is evident. I just feel like the price point is a little high for what is essentially a piece of metal, even if it is premium.

Steven M.★★★★☆October 19, 2009
Essential for Built-In Grills

As a contractor, I always recommend a good quality heat barrier for outdoor kitchens, and this Sunstone panel fits the bill perfectly. The 42-inch size is versatile for many grill setups, and the smoke deflector is a nice touch for keeping things clean. It's a solid, professional-grade product.

William D.★★★★★March 17, 2011
Perfect Finish for My BBQ Area!

Wow, this 42-inch Sunstone grill wall panel totally completed my outdoor cooking space! The 304 stainless steel looks fantastic and the smoke deflector really works to keep my stone backsplash from getting stained. It was super easy to install and feels incredibly durable. Highly recommend for any serious outdoor chef!

Questions & answers

5 questions answered

Q
Will this Sunstone panel be compatible with my 40-inch grill, or is it strictly for 42-inch models?Asked by Sunstone Support Team
A
While the Sunstone® 42" 304 Stainless Steel Grill Wall Panel is named for its 42-inch width, it's designed to provide heat and smoke protection for a range of grill sizes. For a 40-inch grill, this panel will offer excellent coverage, providing a bit of extra protection on either side. Just ensure your overall island opening can accommodate the 42-inch panel dimensions.
