December 22, 20241 yr I'll be fitting a (used) Bora hob soon as "flush" mounted in the worktop. I have the official "sealing tape" so hopefully the official dimensions for the rebate are correct. Just in case it sits a little low though... ...can somebody who has seen these fitted describe that the "height adjustment plates" look like please? (what material, what length/width/thickness and how many?) If it's just e.g. 0.5 mm plastic or soft metal (copper?) spacers I can improvise. 🙂 Thanks!
December 28, 20241 yr Author I mostly chickened out. But I did partially recess it. These sit on the steel frame bonded to the glass. There's then a seal between the glass and the worktop (plus an additional silicone strip if flushed in) Knock a 1.5 mm rebate in the worktop and you're left with 0.5 mm of silicone and 4 mm of glass; vs 6 mm of glass/steel plus whatever texture the worktop has. Marginal; but you'd be surprised at the difference between 4.5 mm and 6 mm visually. Recessing officially/ properly in laminate means routing out the back of the worktop, casting a rung of resin up to the back of the laminate top in place of the wood, then cutting I to that to mount the hob in a ring of resin. I wasn't that brave/bothered. 4 kg.of epoxy about €80 gets you a 3*4 cm ring fwiw.
December 28, 20241 yr Author Alloy tape avoids gluing the cooker to the worktop (instructions say no) for ease of future servicing. Expansion of borosilicate glass is minimal. 0.8 m length at +100C delta (across the whole thing) gives 0.3 mm expansion. The 0.5 mm thick seal can tolerate 0.15 mm in each direction.
