Laminate confusion

[LeeST]

Hi guys,

My little extension is almost complete so will be looking at flooring very soon

Now I have laid laminate a few times and do ok with it, but am looking for advice on the best way to finish it against some internal doors.

Basically I have added another room onto my existing living room. The new room will have oak bi folds that came with a threshold 20mm high. I have bought laminate floor but 2 different colours. One for each room. I want to lay the boards so the short (cut) ends are up against the threshold, same in both rooms

Now threshold is 20mm high, floor is 12mm thick with 5mm insulation. Giving me a 3mm step. ( threshold could be raised a few more mm if required).

What’s the easiest and smartest way to tidy it up where it meets the threshold? One guy (who isn’t a joiner suggested laying the boards the other way round and butted up against the threshold with the tongue cut off , I don’t want them this way round.

He also suggested cutting them leaving a small 5mm gap and filling with silicone.

Both these seem a complete bodge.

Can’t seem to find any other suggestions on google?! Bearing in mind it’s likely to be walked on a fair bit so has to be durable

The existing (or soon to be) threshold for the bifolds has to be there and cannot be taken away

Thanks!

Quadrant moulding that will hide the cut gaps, or cut very carefully to length with some suitably coloured sealant to hide any differences?

A transition strip where they meet? That means your end cuts needn't be perfect and also functions as an expansion joint as well as (some) being able to take out minor differences in height. The door casings I'd carefully undercut with a multitool

With a small lip you could edge the threshold with cork expansion strip giving a neat edge and pack underneath where boards meet threshold to leave it all flush .
Or fit an extra wide threshold over the top of current to hide any expansion gap and the cuts.

Thanks guys.

Have attached a picture this time to see if it’s more clear.

The threshold in the middle is 20mm high, this can’t be covered with anything as doors attach to this.

The floor height both sides is 12mm + 5mm underlay so that’s 17mm.

Floor colour at one side is like a brown and other side is a grey (or will be).

So kinda want something to cover over the expansion gap and somehow blend in a little bit.

Threshold is also 2.4m wide so could do with something on one piece.

Perhaps cork to fill the gap and some strip wood glued to the top of the cork so the floor floats underneath?

Unless the floor track can be designed with a profile that will cover the cut ends of the flooring, the only alternative would seem to be a wooden or plastic moulding, attached to the side of the track with sealant or adhesive thus permitting expansion.

I'm a real glutton for punishment but I would cut a 10mm deep, 13mm high rebate under that threshold (multi-tool and angle grinder), stop the underlay a bit away from the threshold and the laminate will go under. Alternatively, screw some decent quality brown plastic 20mm angle to the threshold and fit laminate under.
My old house had similar style 1" thresholds at the bottom of every doorframe and I have done both of the above, the easiest was the plastic angle, I managed to find some good strong stuff about 3mm thick.
