The short answer
Buy one half-sheet mat if you bake cookies, and keep parchment for everything else. A silicone mat is a reusable non-stick surface with a fiberglass core, and it works because it does not stick and because it evens out hot spots. The cost is browning: it insulates the underside, so roast vegetables come out pale and pastry bottoms stay soft. Nordic Ware publishes a 450F ceiling on its mat, which rules out high-heat roasting and every broiler job.

Nordic Ware Silicone Baking Mat
A published 450F ceiling, a 16 by 11 in half-sheet footprint and a 5-year warranty - three specifications most mats do not state at all.

What a silicone mat actually is
A sheet of food-grade silicone with a woven fiberglass mesh set inside it. The silicone gives the non-stick surface and the temperature tolerance; the fiberglass gives it dimensional stability so it lies flat instead of curling in the oven.
Nordic Ware publishes that construction plainly - food-grade silicone with an encapsulated fiber core, a 16 by 11 in cooking surface sized to a standard half sheet, a 450F maximum, a published instruction not to expose it to direct open flame, and a 5-year warranty. That is more than most makers in this category publish.
A wrinkle worth recording: the same page publishes both "dishwasher safe" and guidance to hand wash in warm soapy water and dry thoroughly. Both statements are the maker's. We have not resolved them and we are not going to pretend one of them is the real answer.
The trade-off nobody puts on the box
Silicone is a poor conductor. A mat between a hot pan and food is a layer of insulation, and it does exactly what insulation does.

A mat is a specialist. It is the best surface in the kitchen for four or five specific jobs and actively the wrong one for roasting, which is what most sheet pans are used for.
This is the same argument as sheet pan materials: what sits between the pan and the food changes the result as much as the pan does.
Mat against parchment
Buy a mat if
You bake cookies regularly enough that parchment is a running cost.
You make meringue, macarons, brittle or anything sugar-based that welds itself to a pan.
You want a surface that does not slide around the pan.
Stay with parchment if
You mostly roast. Parchment insulates less and tolerates more heat.
You want to lift a whole tray of something off the pan in one movement.
You line round pans, loaf pans or anything not rectangular.
You would rather not wash and store a floppy 16 inch sheet.
Silicone degrades above its rated ceiling: it can become tacky, discolor, and in the worst case give off an odor that transfers to food. The published number is the number.
450F is the Nordic Ware figure on the mat we have audited. Plenty of roasting is done at 425 to 450F, so this is a real constraint rather than a theoretical one.
Never under a broiler, at any rating. A broiler element radiates far above the oven's set temperature.
Never over direct flame, which Nordic Ware publishes explicitly.
Check the ceiling on any mat you buy. Where a maker does not publish one, that absence is the specification.
The broader material-safety question - what silicone is, what the FDA says about food-grade grades, and what the filler test tells you - is in is silicone bakeware safe.
Care, storage and the thing that ruins them
Wash with hot soapy water and dry completely. Trapped moisture under a rolled mat is how they start to smell.
Never cut on one. A pizza wheel or a knife severs the fiberglass and the mat delaminates from that point onward.
Store flat or loosely rolled, never folded. A crease becomes permanent.
Do not use aerosol cooking spray on one. It builds a sticky polymerized film that is very hard to remove - the same residue problem coated pans get.
If it goes tacky, a paste of baking soda scrubbed in and left for fifteen minutes removes most of it. If that fails, the mat is finished.
What we have not audited
We have published specifications for one mat. The other well-known name in this category publishes a temperature range and a use count, but its site was not reachable from our build machine when this page was compiled, so we are not quoting figures we could not read ourselves. For the wider category: half-sheet silicone baking mats.
Which to buy
One mat, most kitchens:a half-sheet mat and parchment for everything else.
You roast more than you bake: buy neither. Buy a second half sheet pan and use it bare.
You bake in round and loaf pans: parchment, cut to shape. A flat mat cannot help you.
Each write-up below gives the published specs, what the pan is genuinely good at, what it costs you, and who should skip it. The trade-off line is there on the top pick too — a recommendation with no downside is an advertisement.

Aluminum conducts at 237 W/m-K, which is why it browns evenly and a steel pan does not
The encapsulated steel rim is the reason it does not warp in a hot oven
Lifetime warranty on a pan this cheap
Not good
Nordic Ware does not publish a gauge figure, so thickness cannot be compared like for like
Bare aluminum stains and reacts with acid
Not dishwasher safe by the maker's own advice
The trade-off. Bare aluminum discolors and reacts with acid. It will look used within a month and Nordic Ware advises against the dishwasher.
Skip this if. You want a pan that stays looking new, or you will not hand wash. Buy an aluminized-steel coated pan instead and accept the coating as a wear item.
›Are silicone baking mats better than parchment paper?
For cookies, meringue and sticky sugar work, yes - they release better and they are reusable. For roasting and pastry, no: a mat insulates the underside, so you lose the browning parchment allows. Most kitchens want one mat and a roll of parchment.
›What temperature can a silicone baking mat take?
Nordic Ware publishes 450F for its mat, along with a warning against direct open flame. Ceilings vary by maker, so check the published figure - and never use any mat under a broiler, because the element radiates far above the oven's set temperature.
›Why don't my vegetables brown on a silicone mat?
Because silicone is a poor conductor and the mat is a layer of insulation between the hot pan and the food. Browning underneath needs direct contact with metal. Roast on a bare sheet pan instead.
›Can you cut on a silicone baking mat?
No. A knife or pizza wheel severs the fiberglass mesh inside the mat, and it delaminates from that point. Slide the food onto a board first.
›How do you clean a sticky silicone mat?
Hot soapy water first, then a paste of baking soda scrubbed in and left for about fifteen minutes for residue. The usual cause is aerosol cooking spray, which polymerizes into a film - avoid it on mats entirely.
