Wood Insert Faceplates, Surrounds & Trim Kits: How to Choose and Measure

Updated August 11, 2026

When you put a wood insert into an existing fireplace, there's almost always a gap. The insert is a box, the fireplace opening is bigger than the box, and the difference is a ragged margin of old brick and dark space around the edges. A faceplate — also called a surround, a surround panel, or trim — covers that gap. It's the flat panel that frames the insert and makes the whole thing look like it was meant to be there instead of stuffed into a hole.

It's mostly a finishing piece, not a performance one. But it's not optional in the way it sounds, because without it you're looking at the rough fireplace opening and, depending on the install, an air gap that shouldn't be left open. Everything below is from our Insert Faceplates & Liners collection, where the full lineup lives.

Cut-to-fit versus fixed size

There are two approaches, and which one you need depends on how predictable your fireplace opening is.

A cut-to-fit faceplate comes oversized, in lighter-gauge steel, and you trim it down to match your opening. This is the one to get when your fireplace is an odd size or out of square, which masonry fireplaces often are. The tradeoff is you're doing the cutting, so it takes a little more work and a steady hand with the right tool. We carry a 32 by 50 inch cuttable faceplate in 18 gauge for the Drolet Escape 1800-I, and a 32 by 44 inch cuttable faceplate for the Englander Blue Ridge 150-I.

A fixed-size faceplate with a trim kit comes ready to mount and looks more finished, often with a nickel or black trim edge that frames it cleanly. This is the better pick when your opening is a standard size the panel already matches, or when the insert is designed to pair with a specific surround. We stock these in a couple of sizes, like a 29 by 44 inch and a larger 32 by 50 inch, both with nickel trim.

Which insert surround fits your model

Every panel we stock, in one place. "Fits" comes straight from the manufacturer's fitment — if your insert isn't listed, or you're not sure, send us the model number and we'll confirm before you order.

Measure before you order

This is where faceplate orders go wrong. Measure the actual fireplace opening, height and width, and have your insert model number handy. The faceplate has to be larger than the opening so it overlaps and covers the edges, but not so large it runs past the usable wall around the fireplace. With a fixed-size panel, if your opening is bigger than the panel, it won't cover, and you're stuck. With a cuttable one you have more room for error since you're trimming to fit.

If you're matching a faceplate to a specific Drolet or Englander insert, the model determines what fits. And if your insert is an Enerzone or Osburn — built on the same SBI platforms — send us the model and your opening dimensions and we'll tell you which panel works before you buy, because returns on the fixed-size panels are a hassle nobody enjoys.

The liner that goes in with it

A faceplate finishes the front of an insert install — the chimney liner makes it work. Insert manuals call for a full-height stainless liner from the insert's collar to the top of the chimney, so most people order both at once. The 25-foot and 35-foot insert liner kits cover standard chimney heights, the hook-up liner system makes the collar connection on the Escape 1800-I and Blue Ridge 150-I/300-I/500-I, and the offset liner adaptor handles a flue that doesn't line up with the collar. Full sizing and install detail is in our chimney liner guide.

Every faceplate and liner kit ships with No Sales Tax, and orders over $250 ship free in the lower 48.

Common questions

Do I need a faceplate for my insert? If the insert sits inside a larger fireplace opening, almost certainly yes, to cover the gap and finish the look. Some inserts come with a surround included, so check what's in the box first.

What's the difference between a faceplate, a surround, and a trim kit? They're mostly the same idea with different names. The faceplate or surround is the flat panel covering the gap. A trim kit is the edge framing, sometimes sold with the panel, sometimes the finishing strip that cleans up the outer edge. In practice you're buying the panel that fits your opening, whatever it's called.

What size surround do I need for my insert? Measure your fireplace opening's height and width. The surround must be larger than the opening on every side so it overlaps and covers the edges — the standard panels we stock are 29 by 44 and 32 by 50 inches, and the cuttable versions give you margin on odd-sized openings. Match it to your insert model, not just the opening.

Can I cut a faceplate myself? The cuttable ones, yes, that's what they're for. They're lighter gauge so a jigsaw or angle grinder with a metal blade handles it. The fixed-size trim kits are not meant to be cut, so size those carefully.
