I wouldn't use flame guns as they burn fossil fuel, quite a poor environmental choice, especially factoring in the need for repeat treatments.
Glyphosate, the basic weedkiller, is what you want. Keep pets away for an hour then get on with life as usual
Weighed against the impact manufacturing Glyphosate how does the flame gun stack up?
Or we could go much deeper, what is the overall environmental impact of the manufacture, shipment, use (including other required equipment), waste disposal, residuals etc.
Although Glyphosate is the better choice for the job, the argument is possibly a poor choice.
I'm well-versed in Environmental Impact Assessments and Life Cycle Analyses... this is my balanced view on things! Given the longer lasting result from weedkiller, the manufacture, transport and disposal of propane cannisters, short-lived results and fuel use, not to mention the labour requirement.
But the same arguments can go against glyphosate, with the exception of longer term weed reduction.
The manufacture of the chemicals most likely uses more fossil fuel than the manufacture and use of the propane canister ( and I’m leaving out the various transport legs of each product ). You would need more of each.... so the environmental argument is a poor one when considering a few weeds between some paving flags.
I assumed by labour requirement you meant application of weedkiller v flame

You'd be surprised how efficient the manufacture of glyphosate is!
Flame guns don't even kill weeds...just burn the leaves. They grow back.
I've done my own analysis and I have firmly chosen the best method. Given 100ml can treat a full 100m2, which when spot spraying driveways could be ten driveways... tiny amounts are required for full and total weedkill
id start with using a pressure washer to get rid of any soil build up (most weeds will go with the soil) then any ones that are left growing i'd pour boiling water over them.
In my experience, tho the results are very good, pressure washers make a lot of mess especially if the paved area has slow drainage. It would still be the best option in winter because there's not enough light and it's too wet for glyphosate which needs 8 hours of dry to be absorbed down to the roots and be effective.

After pressure washing, or even strimming the weeds down, one of these will do the trick - https://www.worldofwolf.co.uk/categories/multi-change-tools/product/wolf-garten-multi-change-garden-scraper/FKM~FKM and then a choice of short, medium or full length handles.
